Product Introduction

The NCEP4040Q uses Super Trench technology, uniquely optimized to deliver the most efficient high-frequency switching performance. Thanks to the very low combined RDS(ON) and Qg, both conduction loss and switching loss are minimized. This device is ideal for high-frequency switching and synchronous rectification applications.

Core Advantages

  • Ultra-low on-resistance and gate charge, excellent FOM; 40V/40A in DFN3.3x3.3; EAS=115mJ; 100% UIS tested; ideal for high-frequency switching and synchronous rectification

Key Features

Excellent FOMbalanced conduction and switching losses, both low under high-frequency operation, ideal for high-frequency switching and synchronous rectification;
Small package, high currentDFN3.3x3.3-8L ultra-compact package, 40A continuous current, still 28.3A at 100℃ case temperature, 160A pulsed peak current, suitable for high-density power boards;
Full reliability screening100% UIS and 100% ΔVds factory testing; single-pulse avalanche energy EAS=115mJ, good device consistency, withstands inductive load pulse surges;
Fast switching and good reverse recoveryshort switching delay and rise/fall times; body diode reverse recovery time Trr typically only 11ns with low reverse recovery charge, reducing diode freewheeling loss and ringing in synchronous rectification.

Alternative Products and Reasons

  • Infineon: BSZ040N04LS G;
  • AOS: AON7240;
  • Vishay: SiS434DN. Replacement reason: matching parameters, compatible package, no PCB redesign required, enabling localized cost reduction.
