Electronic door latches must release reliably on command, including in a crash, when conventional mechanical latches can jam. They demand compact actuator electronics, reliable power delivery, and sufficient energy storage to support controlled operation under normal and emergency conditions, resisting the shock and vibration of a collision event.

Vishay's power MOSFETs drive the solenoid or motor that releases an e-latch mechanism, while capacitors provide the reserve energy needed to actuate the latch even if primary power is interrupted. Our Automotive Grade resistors, connectors, diodes, and protection components provide building blocks for switching, power management, and transient control for the low latency control circuit an e-latch depends on.

Behind e-latch reliability is The DNA of tech.®
