Vishay expands its VOR family of hybrid solid-state relays

  • Hybrid Solid-State Relays Provide Fast Operation, Wide Temp. Range, and High Load Voltage

  • Single- and Dual-Channel 1 Form A Devices Switch AC and DC Loads, Are Manufactured on Highly Integrated Production Line

Vishay Intertechnology today expanded its VOR family of hybrid solid-state relays with four new devices designed to deliver superior electrical characteristics for telecommunications, industrial, security system, and metering applications. Compared to similar solutions, the new Vishay Semiconductors 1 Form A VOR1121A6, VOR1121B6, VOR2121A8, and VOR2121B8 provide faster, bounce-free switching and a wider operating temperature range, and are more cost-effective.

hybrid solid-state relays, Vishay IntertechnologyThe relays released today are single-channel (VOR1121A6 and VOR1121B6) and dual-channel (VOR2121A8 and VOR2121B8) normally open single-pole, single-throw (SPST) switches. The devices’ hybrid architecture enables fast typical turn-on and turn-off times of 0.20 ms and 0.03 ms and an ambient temperature range of -40 °C to +100 °C. A high-efficiency GaAIAs IRED enables low forward current on the input side. On the output side, high-performance MOSFET switches provide low on-resistance of 12 Ω to reduce power dissipation. The VOR1121A6 and VOR1121B6 can be figured for DC-only operation to reduce the on-resistance.

The VOR1121A6 and VOR2121A8 are offered in DIP-6 and DIP-8 packages, respectively, while the VOR1121B6 and VOR2121B8 feature the SMD-6 and SMD-8. All four devices offer a high isolation test voltage of 5300 VRMS and load voltages of 250 V. The solid-state relays are VDE- and UL-certified to meet the insulation requirements for most applications. All devices are manufactured in-house on a highly integrated production line.

The VOR1121A6, VOR1121B6, VOR2121A8, and VOR2121B8 offer clean, bounce-free switching, current limit protection, and low power consumption. Typical applications will include alarm and telecom switches, I/O cards, automation, battery management systems, and automatic test equipment. Available in tape-and-reel and tube packing, the devices are RoHS-compliant, halogen-free, and Vishay Green.

Samples and production quantities of the new solid-state relays are available now, with lead times of four to six weeks for large order
