Vishay Intertechnology Introduces New Family of Hybrid Solid-State Relays Offering High-Reliability Replacements for Mechanical Relays
Three New 1 Form A, Single-Channel Relays Provide Noiseless Switching, Feature Current Limit Protection and High Input-to-Output Isolation
MALVERN, Pa. — Sept. 15, 2015 — Vishay Intertechnology, Inc. (NYSE: VSH) today introduced the first three devices in its new VOR family of hybrid solid-state relays designed to deliver high reliability and noiseless switching for telecommunications, industrial, security system, and metering applications. As replacements for traditional mechanical relays with lower reliability and shorter lifetimes, the new Vishay Semiconductors 1 Form A VOR1142A6, VOR1142B6, and VOR1142M4 provide high input-to-output isolation, current limit protection, and low power consumption.
The relays released today are normally open single-pole, single-throw (SPST) switches. Allowing for simple customization, the devices feature a modular construction consisting of a GaAIAs (gallium aluminum arsenide) IRED actuation control and MOSFETs for the switch output.
The single-channel relays are offered in DIP-6 (VOR1142A6), SMD-6 (VOR1142B6), and SOP-4 (VOR1142M4) packages. Devices in the SMD-6 and DIP-6 packages offer high isolation test voltage of 5300 V / 1 min, while devices in the smaller SOP-4 offer isolation test voltages of 3750 V / 1 min. All relays offer low typical on-resistance of 22 Ω, high load current of 140 mA, load voltage of 400 V, and very low turn-on current of 0.25 mA typical. The devices are VDE and UL certified to meet reinforced insulation requirements for most applications.
Electronically isolated, the VOR1142A6, VOR1142B6, and VOR1142M4 offer clean, bounce-free switching over an ambient temperature range of -40 °C to +100 °C. Typical applications will include line, load, ground, signal, and alarm switches; I/O cards; ground isolation; electro-mechanical noise isolation; automation; automatic test equipment; and motor drives.
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 1 Form A solid-state relays are available now, with lead times of eight to 10 weeks for large orders.
