IR Introduces Photovoltaic Relays with 50% Lower On-State Resistance

September 24, 2006 by Jeff Shepard

International Rectifier Corp. (IR)® introduced a series of photovoltaic relays for applications including computers and computer peripherals, power supplies and power distribution, audio equipment, and instrumentation. Compared to its predecessor, the PVN012A family offers a 50% reduction of ac-dc on-state resistance (RDD-on) and a 37.5% increase of maximum ac-dc load current rating at full (100%) duty cycle. The new series is also rated for maximum pulsed (surge) load current.

"With extremely low on-resistance and high volumetric load current density in such a small package, the PVN012A family exceeds the performance capabilities of traditional electromechanical relays," said Andy Serkuczewski, Product Manager, Energy-Saving Products. When compared to traditional electromechanical relays, the PVN012A family offers a smaller footprint, high input-to-output isolation, bounce-free operation, solid-state reliability, stable on-resistance over life, and greater input sensitivity.

These new 20V single-pole, normally open, solid state relays utilize a HEXFET® MOSFET output switch, driven by a unique integrated photovoltaic generator circuit. The output switch is controlled by radiation from a GaAlAs light-emitting diode (LED) that is optically isolated from the photovoltaic generator. The new series is available in 6-pin DIP, 6-pin SMT, and in tape and reel.

All in 10,000 unit quantities, pricing begins at US $3.59 each for the PVN012APbF, $3.62 for the PVN012ASPbF and $3.67 for the PVN012AS-TPbF. Production orders are available immediately. The devices are RoHS compliant.
