NVH820S75L4SPC

Overview

The NVH820S75L4SPC is a single-side direct cooling 6-pack power module from the VE-Trac/C0116 Direct family, designed for hybrid and electric vehicle traction inverters. It integrates six Field Stop 4 (FS4) 750 V Narrow Mesa IGBTs with fast recovery diodes in an SSDC33 package. The module supports a continuous DC collector current of 600 A at 175°C junction temperature and handles pulsed currents up to 1640 A. Key electrical parameters include a maximum blocking voltage of 750 V, isolation voltage of 4200 V DC, and stray inductance of 8 nH. Thermal performance features a junction-to-fluid thermal resistance of 0.11°C/W for the IGBT and 0.185°C/W for the diode under specified cooling conditions.
