Vishay releases 1500V SSR for 800V battery monitoring systems
Vishay Intertechnology has 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 VORA1150 combines a high 1414 Vpeak repetitive isolation voltage with a low maximum leakage current of 1 µA.
The 4-pin design of the relay 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, 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.
