Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The BSZ440N10NS3G is an N-channel power MOSFET introduced by Infineon, belonging to the OptiMOS™ 3 series, and is packaged in a PG-TSDSON-8 package. This device is specifically designed for high-efficiency, high-power-density power conversion applications, featuring low on-resistance, fast switching capability, and high reliability.

BSZ440N10NS3G Product Features

Low on-resistance: RDS(on) as low as 1.1 milliohms, significantly reducing power loss and improving system efficiency.

Fast switching capability: Low gate charge (Qg = 9.1 nC @ 10 V) supports high-frequency operation scenarios, reducing switching losses.

High current handling capability: Continuous drain current (Id) up to 18 A (Tc), pulse current (Idp) up to 660 A.

High reliability: Complies with the automotive electronics industry standard AEC-Q101, ensuring stable operation in harsh environments.  

Environmental compliance: Complies with RoHS standards and is halogen-free.  

Compact packaging: Uses PG-TSDSON-8 packaging, which is small in size and saves PCB space.
