The new relays include the single-channel (VOR1121A6 and VOR1121B6) and dual-channel (VOR2121A8 and VOR2121B8) normally open single-pole, single-throw (SPST) switches. The hybrid architecture of the devices 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 SMD-6 and SMD-8 packages. 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.
Typical applications include alarm and telecom switches, I/O cards, automation, battery management systems and automatic test equipment.
Samples and production quantities of the solid-state relays are available now, with lead times of four to six weeks for large or
