International Rectifier has introduced the PVT412A series microelectronic relays. They have twice the load current capability at ±400 V off-state blocking with less than a quarter device on-resistance than the earlier PVT412 series MERs.
The relays can replace electromechanical relays, enabling gains in operational life and reliability over electromechanical relays, with smaller size and higher sensitivity.
Other benefits include bounce-free (noiseless) switching, reduce power consumption through lower actuation currents and high levels of immunity to shock and vibration.
Typical applications include on/off hookswitch, ringer injection, ground start and general switching.
In addition to telecom applications, the PVT412A devices can replace electromechanical and reed relays in applications where high reliability and low on-resistance are required, such as remote utility metering and high voltage AC and DC industrial load switching.
The devices are rated for AC/DC load switching applications up to 240 VAC RMS and 300 VDC at 240 mA, and DC-only loads up to 300 V at 360mA.
