New 1500 V AEC-Q102 solid-state relay targets 800 V BMS and EV isolation monitoring with strong isolation and low leakage.

The VORA1150 is a 1 Form A solid-state relay in a 4-pin SMD-8 package designed for 800 V battery monitoring systems. It pairs a high repetitive isolation voltage of 1414 Vpeak with a low maximum leakage current of 1 µA, plus a 5 mm creepage distance on output pins to meet DIN EN-60644-1 requirements. The device is AEC-Q102 qualified, meets hipot test requirements for 800 V EV architectures, and offers an isolation test voltage of 5300 VRMS, CTI 600 mold material, and an operating range of -40 °C to +125 °C, which supports automotive-grade reliability needs.

Key dependencies and risks include system-level verification that the specified leakage and isolation hold under real-world stress and assembly conditions, and integration of the 4-pin layout into existing BMS PCBs without compromising creepage in end designs. Lead time of eight weeks affects near-term adoption. Monitor availability of production samples now, qualification feedback from OEM BMS suppliers over the next several months, and any published datasheet test matrices; these will clarify fit for safety-critical monitoring and time-to-deployment for automotive and energy-storage customers.

AEC-Q102 Qualified Device Offers V_IORM of 1414 V_peak, Low Max. Leakage Current of 1 µA, and 5 mm Creepage Distance on Output Pins

MALVERN, Pa., Nov. 25, 2025 (GLOBE NEWSWIRE) -- Vishay Intertechnology, Inc. (NYSE: VSH) today introduced a new 1500 V Automotive Grade 1 Form A solid-state relay in a 4-pin SMD-8 package. Designed for 800 V battery monitoring systems in automotive, energy storage, and industrial applications, the Vishay Semiconductors VORA1150 combines a high 1414 V_peak repetitive isolation voltage with a low maximum leakage current of 1 µA.

The innovative 4-pin design of the relay released today allows the device to provide a 5 mm creepage distance on its output pins, as required by the DIN EN-60644-1 standard for isolation monitoring applications in 800 V battery monitoring systems. In addition, the VORA1150 meets hipot test requirements for 800 V battery architectures in electric vehicles (EV).

The AEC-Q102 qualified device enables isolation and leakage current monitoring in battery management systems (BMS), pre-charge relays, and on-board chargers; energy storage systems (ESS); industrial HVAC systems; and solar panels. In these applications, the relay’s high repetitive isolation voltage and mold material with a comparative tracking index (CTI) of 600 provide increased reliability, while low maximum turn-on and turn-off times of 150 µs and 250 µs, respectively, ensure fast operation.

RoHS-compliant, halogen-free, and Vishay Green, the VORA1150 offers an avalanche current capability of 0.9 mA, isolation test voltage of 5300 VRMS, and operating temperature range of -40 °C to +125 °C.

Samples and production quantities of the new 1 Form A solid-state relay are available now, with lead times of eight weeks.
