The relays are normally open SPST switches. Allowing for simple customisation, the devices feature a modular construction consisting of a GaAIAs 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 a high isolation test voltage of 5300V/min, while devices in the smaller SOP-4 offer an isolation test voltage of 3750V/min. All relays offer low typical on-resistance of 22Ω, high load current of 140mA, load voltage of 400V, and very low turn-on current of 0.25mA 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 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 solid-state relays are available now, with lead times of eight to 10 weeks for large orders.
