PD414010

Overview

The Powerex PD414010 is a POW-R-BLOK dual diode isolated module rated for 1000 Amperes average forward current and up to 4000 Volts repetitive peak reverse blocking voltage. It features an electrically isolated heatsink design with a metal baseplate, allowing direct mounting on common heatsinks without additional insulation components. The module utilizes compression bonded silicon elements to ensure low thermal impedance and high current capability. Key electrical ratings include a maximum non-repetitive surge current of 48,300 A at 60 Hz and a junction-to-case thermal resistance of 0.029 °C/W per module.
