SSDI Upgrades SDA312 Series of Three Phase Bridge Assemblies
New SDA312 bridge assemblies deliver 50% increase in output current
and 50% improvement in thermal resistance

 La Mirada, CA – June 14, 2012 – Solid State Devices, Inc. announces their enhanced SDA312A - SDA312G and SDA312AF - SDA312GF series of three phase bridge assemblies. These bridge assemblies deliver 15 Amps of forward current and a maximum thermal resistance of 3.5°C/W, which equates to a 50% increase in output current and a 50% improvement in thermal resistance over their previous versions. The high reliability, ultraminiature packaging consists of glass passivated void free hermetically sealed discrete rectifiers in an electrically insulated aluminum case for maximum thermal conductivity.

Both series feature a blocking voltage range of 50 to 1000 volts and a low reverse leakage current of 5 µA. The SDA312A - SDA312G series includes standard reverse recovery devices with a maximum rating of 5 µsec, and the SDA312AF - SDA312GF series are fast recovery devices with a maximum rating of 200 nsec. Contact the factory for ultra fast and hyper fast recovery versions.

The SDA312 bridge assemblies are available and can be screened at TX, TXV, or S level. Screening is based on MIL-PRF-19500 and screening flows are available on request. Contact SSDI today for more information and product samples.
