International Rectifier Introduces 20V Microelectronic Power IC Photovoltaic Relays with 50 Percent Lower On-State Resistance

International Rectifier » PVN012A

International Rectifier, a world leader in power management technology, today 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 percent reduction of AC/DC on-state resistance (RDD-ON) and 37.5 percent 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.
