Vishay's VO1400AEFTR solid-state relay

Vishay Intertechnology Inc. has announced the VO1400AEFTR, a miniature 1-Form-A solid-state relay (SSR) with on-resistance of 5 ohms, trigger current of 1mA and load voltage of 60V. Using an optical medium, the new device provides clean, bounce-free switching for indoor security, instrumentation and industrial control systems.

Packaged in the 4-pin SOP, the new device's 4.7-by-7.4mm footprint provides up to 75 percent space savings on PCBs, the company said, enabling smaller form factors for passive infrared sensors, electronic access controls, test instruments, circuit board testers and semiconductor test equipment.

Its low input trigger current makes it easy to interface the device to standard logic circuits, while the low output on-resistance and load voltage parameters benefit systems designed for low power operation, said Vishay. The device is rated for an isolation test voltage of 1500V. Solid-state construction results in arc-free switching, magnetic interference immunity and a longer operating life compared to electromechanical reed relays.

Samples and production quantities of the VO1400 are available today, with lead times of six to eight weeks for larger orders.
