Overview
The NVXR17S90M2SPB is a Silicon Carbide (SiC) power module from onsemi's EliteSiC family, designed for traction inverter applications. It features a 6-pack configuration with a 900 V drain-to-source voltage and a continuous DC drain current of 620 A at 175°C junction temperature. The typical on-state resistance is 2.1 mΩ at 25°C and 2.3 mΩ at 175°C. Operating within a -40°C to +175°C range, the module utilizes direct cooling via an integrated pin-fin heatsink baseplate. Key electrical parameters include a gate threshold voltage of 2.7 V, total gate charge of 2.4 μC, and isolation voltage of 4200 V AC.
Feature Summary
- Direct cooling capability with an integrated copper pin-fin heatsink baseplate
- Automotive-grade silicon carbide MOSFET technology compliant with AQG324 standards
- High-reliability sintered die attach technology for thermal performance
- Six-pack topology with press-fit signal terminals for simplified assembly
Applications
- Hybrid electric vehicle traction inverters
