AEC-Q200 Qualified Device in Compact SOT-227B Package Offers High Pulse Handling Capability and Power Dissipation to 200 W

MALVERN, Pa., April 23, 2025 (GLOBE NEWSWIRE) -- Vishay Intertechnology, Inc. (NYSE: VSH) today introduced a new AEC-Q200 qualified thick film power resistor in the compact, low profile SOT-227B package for mounting on a heatsink. Available with an optional NTC thermistor for internal temperature monitoring and pre-applied Phase Change Thermal Interface Material (PC-TIM) for more efficient mounting, the Vishay MCB ISOA200 offers high pulse handling capability and high power dissipation up to 200 W at an 80 °C bottom case temperature.

Built on an exposed alumina substrate instead of a metal tab, the device released today lowers costs and weight for automotive, industrial, and avionics, military, and space (AMS) applications, in which it will serve as a precharge, discharge, active discharge, or snubber resistor. For applications subject to high and repetitive pulse surges, the resistor can handle high energy pulses up to 140 J for 0.1 s and is multi-pulsed tested. Additional custom testing options for the device are also available.

With the option to integrate an AEC-Q200 qualified, temperature cycle tested NTC thermistor inside the resistor package, the ISOA200 simplifies designs and saves board space, while its optional PC-TIM streamlines installation in production. The device’s high power and high energy dissipation further simplify designs while lowering costs by reducing the need for power components.

The ISOA200 features a resistance range from 10 Ω to 1 MΩ, with tolerances of ± 5 % and ± 10 %, and TCR of ± 100 ppm/K and ± 150 ppm/K. The resistor offers a maximum operating voltage of 1500 V, an operating temperature range of -55 °C to +150 °C, and dielectric strength of 4000 Vrms. The RoHS-compliant device offers a non-inductive design and can include two different resistors.

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