NFVA23512NP2T

Overview

The NFVA23512NP2T is a 3-phase, 1200V, 35A automotive intelligent power module (IPM) designed for hybrid and electric vehicle inverter output stages. It integrates optimized IGBT gate drivers to reduce electromagnetic interference and switching losses. The module features built-in high-voltage integrated circuits (HVIC) requiring only a single supply voltage to convert logic-level signals into high-voltage drive currents. Key electrical specifications include a 1200V collector-emitter voltage rating and a 35A continuous collector current capability.

Feature Summary

• Integrates optimized IGBT gate drivers with HVIC technology to minimize electromagnetic interference and switching losses while simplifying control signal interfacing through single-supply operation.
• Incorporates comprehensive protection mechanisms including under-voltage lockout, over-current shutdown, thermal monitoring of the driver IC, and fault reporting capabilities.
• Utilizes low-loss, short-circuit rated IGBTs on an aluminum oxide direct bonded copper substrate to achieve low thermal resistance and enhanced heat dissipation efficiency.
• Features independent negative IGBT terminals for each phase to support diverse control algorithms and includes open-collector pins on low-side IGBTs for dedicated three-phase current sensing.

Applications

• Hybrid electric vehicle traction inverters
• Electric vehicle motor drive systems
• Automotive e-Compressor air conditioning units
