Vishay Intertechnology, Inc., through its Vishay Semiconductors division, has introduced two new industrial-grade 1 Form A solid-state relays housed in compact SOP-4 surface-mount packages. These devices — the VO1401AEFTR and VOR1003M4T — offer a combination of high load current capability , isolation voltage of 3750 VRMS , and low leakage current of less than 1 µA , making them ideal for a wide range of industrial and commercial applications 2.
The VO1401AEFTR supports a continuous load current of 550 mA at up to 60 V , while the VOR1003M4T delivers up to 5 A at 30 V 6. Both relays are designed to replace traditional electromechanical relays, offering contactless optical switching that enhances reliability by eliminating mechanical wear and sensitivity to vibration 2.
These solid-state relays are especially well-suited for use in harsh environments , thanks to their high isolation voltage , which ensures safe operation even under extreme conditions 9. Their fast switching performance — with typical turn-on/turn-off times of 1.3 ms / 0.15 ms (VO1401AEFTR) and 0.5 ms / 0.1 ms (VOR1003M4T) — makes them suitable for time-sensitive applications such as:
- Industrial automation systems and controls
- Security and surveillance equipment
- Medical instrumentation
- Broadcasting and audiovisual systems
The ultra-compact SOP-4 package helps save valuable board space, while the ultra-low leakage current ensures higher system efficiency by preventing unintended activation of sensitive loads on the output side 7.
With these features, Vishay continues to expand its portfolio of space-saving, high-performance semiconductor solutions tailored for modern industrial and electronics applications.
