Vishay Intertechnology XClampR® Bidirectional Flat Clamping TVS in DO-218AC Package Deliver Low Clamping Voltage, High Power Density

Vishay launches a 15-part XClampR TVS family combining 11 kW-class pulse capability with low clamping ratio for automotive and industrial designs.

Rhea-AI Summary

Vishay Intertechnology (VSH) introduced the XFD11KxxCA series of bidirectional XClampR® flat clamping transient voltage suppressors in a surface-mount DO-218AC package.

The 15 new devices, offered in commercial-grade and AEC-Q101 qualified versions, deliver peak pulse power dissipation comparable to 11 kW conventional TVS at 10/1000 μs while maintaining a low clamping ratio (VC/VBR) near 1.0. They provide stand-off voltages from 33 V to 85 V, breakdown voltages from 36.7 V to 104 V, and maximum clamping voltages from 40.6 V to 104.0 V, supporting 12 V, 24 V, and 48 V automotive powertrains. The series offers peak pulse current up to 207.1 A at 10/1000 μs and 8/20 μs surge capability up to 2140 A, over -55 °C to +175 °C, with leakage current up to 10 μA at stand-off voltage. The RoHS-compliant, halogen-free TVS are available now, with lead times of 12 weeks.

News Explained

Compared with conventional DO-218-compatible devices, Vishay’s new TVS offer lower clamping voltage at the same stand-off voltage and approximately 1.6x higher peak pulse current, which the company says can allow lower-voltage downstream components, smaller design guard bands, and lower system costs.

4 terms

transient voltage suppressors technical

"new series of bidirectional XclampR® flat clamping transient voltage suppressors"

Transient voltage suppressors are electronic components that protect circuits from short, sharp voltage spikes by quickly diverting or absorbing excess electrical energy to keep downstream parts safe. They matter to investors because manufacturers and users of these parts supply many industries that need reliable power protection—so sales and product demand can signal strength in electronics, automotive, telecom and industrial markets. Think of them as a pressure-relief valve for electrical systems.

aec-q101 technical

"both commercial-grade and AEC-Q101 qualified versions"

AEC-Q101 is an industry qualification standard that tests discrete semiconductor parts (like diodes and transistors) to ensure they can survive harsh automotive conditions such as heat, vibration and electrical stress. For investors, a part certified to AEC-Q101 is like a car tested for extreme road and weather conditions—it signals lower supply and reliability risk for companies that design or use those components, which can affect production, costs and product credibility.

moisture sensitivity level technical

"feature a moisture sensitivity level (MSL) of 1"

A moisture sensitivity level is a classification that tells how susceptible an electronic component or packaged device is to damage from absorbed moisture during standard manufacturing steps like soldering. Investors should care because a higher sensitivity can increase the risk of production defects, extra handling or storage costs, slower assembly lines, and potential product recalls—factors that affect manufacturing yield, delivery schedules and profit margins.

peak pulse power dissipation technical

"peak pulse power dissipation comparable to 11 kW"

Peak pulse power dissipation is the maximum instantaneous electrical power a device can absorb and convert to heat during a short, high-energy surge (a pulse) without failing. It matters to investors because it describes a component’s ability to withstand spikes—like lightning or switching transients—and so signals product reliability, performance limits, and potential warranty or liability exposure; think of it as the ‘sprint tolerance’ of an electronic part.

Commercial-Grade and AEC-Q101 Qualified Devices Feature Clamping Ratio Near 1.0, Stand-off Voltages from 33 V to 85 V, and Peak Pulse Power Dissipation of 11 kW

MALVERN, Pa., Sept. 10, 2026 (GLOBE NEWSWIRE) -- Vishay Intertechnology, Inc. (NYSE: VSH) today introduced a new series of bidirectional XclampR^® flat clamping transient voltage suppressors (TVS) in the surface-mount DO-218AC package. The industry’s first such devices to provide peak pulse power dissipation comparable to 11 kW conventional TVS at 10/1000 μs — while maintaining a low clamping ratio (VC/VBR) close to 1.0 for high power density — the Vishay General Semiconductor XFD11KxxCA series features 15 devices in both commercial-grade and AEC-Q101 qualified versions.

The TVS released today provide maximum clamping voltages from 40.6 V to 104.0 V, breakdown voltages from 36.7 V to 104 V, and a wide stand-off voltage range from 33 V to 85 V, which supports 12 V, 24 V, and 48 V automotive system powertrains. Compared to conventional devices in DO-218-compatible packages, the XFD11KxxCA series provides lower clamping voltage at the same stand-off voltage, while delivering approximately 1.6x higher peak pulse current — up to 207.1 A at 10/1000 μs.

The TVS feature low and stable clamping and breakdown voltages over a wide temperature range of -55 °C to +175 °C. This allows designers to select lower voltage downstream components — such as MOSFETs and capacitors — to reduce voltage overshoot and enable smaller design guard bands, lowering system costs. The devices provide 8/20 μs surge capability up to 2140 A, supporting low dynamic resistance and flat clamping performance. In addition, they feature low leakage current of 10 μA maximum at stand-off voltage (VWM) to minimize power loss.

The XFD11KxxCA series is designed to protect sensitive electronics against voltage transients induced by inductive load switching and lightning. Automotive applications include ADAS, autonomous driving control units (ADCU), on-board chargers (OBC), DC/DC converters, traction inverters, battery management systems (BMS), body control modules (BCM), park distance control (PDC), oil pumps, camera systems, and automatic air conditioning systems. In addition, the TVS will be used in energy storage systems; industrial servo motor systems, EPS, lighting systems, and automation controls; server power and AI server hot swap; telecom power supplies and T-Box DC/DC power conversion; and radar power supplies.

RoHS-compliant and halogen-free, the devices feature a moisture sensitivity level (MSL) of 1 in accordance with J-STD-020, with a maximum peak reflow temperature of 245 °C. Their matte tin-plated leads are solderable per J-STD-002 and JESD 22-B102.

Samples and production quantities of the new TVS are available now, with lead times of 12 weeks.
