Microelectronic Relay designers manual
from IR to simplify design
International Rectifier has made available of a CD-based
Microelectronic Relay (MER) Designers Manual featuring a
selection guide, application notes, datasheets and design
tips on it's extensive portfolio of MER products.
IR's offering of MERs includes both MOSFET- and IGBT-based
photovoltaic relays and photovoltaic isolator products.
IR says the MOSFET-based devices are solid-state relays
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 packages with center-tap
output configurations allow for added design flexibility
for AC/DC- and DC-only parametric choices. The IGBT-based
photovoltaic relay is for switching industrial loads up
to 400W or 280VA and available in a DIP14 package, the device
is designed as a drop-in replacement for Mercury-wetted
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 of creating their own, custom-made
solid-state relays capable of controlling loads over 1,000
volts and 100 amps says IR.
"International Rectifier offers a range of MER products
with attractive top-of-the-line packaging, semiconductor
switch technology and electrical specification combinations
particularly for industrial control applications. The designers
manual is a convenient resource for selecting and designing
MER products from IR's extensive portfolio," said Andy
Serkuczewski, IR's director of MER product marketing.
IR's MER products are lead-free and RoHS-compliant.
