Photovoltaic relays reduce on-resistance

Photovoltaic relays suit applications such as power supplies, power distribution, audio equipment, and instrumentation, computers and computer peripherals.

International Rectifier has introduced a series of photovoltaic relays for applications including power supplies, power distribution, audio equipment, and instrumentation, computers and computer peripherals.

Compared with its predecessor, the PVN012A family offers a 50% reduction of AC/DC on-state resistance and 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.

When compared with 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 use 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.

The PVN012AS-TPbF is RoHS compliant and production orders are available immediately.
