NVVR26A120M1WST

Overview

The NVVR26A120M1WST is a Silicon Carbide (SiC) half-bridge power module from onsemi's EliteSiC family, designed for traction inverters. It integrates two 1200 V SiC MOSFETs in an AHPM15-CDA package with single-side cooling. Key electrical parameters include a maximum drain-source voltage of 1200 V and a continuous DC current rating of 400 A at 175°C junction temperature. The typical on-state resistance (RDS(on)) is 2.6 mΩ at 25°C and 4.6 mΩ at 175°C. The module features ultra-low stray inductance of approximately 7.1 nH and utilizes sintering technology for die attach to enhance reliability.

Feature Summary

• Integrates M1 SiC technology for high current density and robust short-circuit withstand capability
• Utilizes Aluminum Nitride (AlN) isolated substrate for superior thermal conductivity and basic isolation
• Employs sintered die technology for enhanced mechanical stability and thermal performance
• Features ultra-low stray inductance design to minimize switching losses and voltage overshoot

Applications

• Automotive EV/HEV Traction Inverter

Procurement Notes
