International Rectifier has released a CD-based microelectronic relay designers manual featuring a selection guide, application notes, datasheets and design tips on the company’s portfolio.
The company’s MERs include both MOSFET- and IGBT-based photovoltaic relays and photovoltaic isolator products. The MOSFET-based devices are solid-state relays suitable for switching AC and DC loads and sensory signals from a few milliamps to several hundred watts in industrial controls, instrumentation, peripheral telecom devices, computer peripherals and office equipment.
Devices in the portfolio featuring power MOSFET outputs in a DIP6 package with centre-tap output configurations allow for added design flexibility for AC/DC- and DC-only parametric choices.
The IGBT-based photovoltaic relay is suitable for switching industrial loads up to 400 W or 280 VA. Available in a DIP14 package, the device is designed as a drop-in replacement for mercury-wetted reed relays.
The photovoltaic isolators offer single- and dual-channel, optically isolated outputs that can be used for directly driving the gates of discrete power MOSFETs and IGBTs, allowing designers the flexibility to create custom-made solid-state relays capable of controlling loads of over 1000 V and 100 A.
