SanRex introduces 17mm Low Profile Rectifier Modules
Osaka Japan, --- October 19, 2006 -- Sansha Electric Manufacturing Co., Ltd. the parent company of SanRex Corporation introduces two new device types.

SanRex expands its Three Phase Rectifier Bridge and Dual Rectifier families to include modules with a Low Profile height of 17mm. The new DF-AC series and DD-AB series are designed for applications requiring low profile converter-inverter circuit designs.

Thanks to the 17mm flat case height design, the new DF-AC series and DD-AB series can be connected with IGBT or MOSFET modules at the same 17mm case height. This advantage typically reduces needed parts and manufacturing cost. It also enables level parallel connections for larger capacity, contributes to reducing stray inductance, improving high efficiency and reliability.

The new DF-AC series also features very low maximum peak forward voltage (VFM) up to 11% lower and very low thermal resistance, Rth(j-c) up to 14% lower compared to conventional devices.
