BSB053N03LPG Description

Short technical summary and product information.

The BSB053N03LPG is an N-Channel power MOSFET manufactured by Infineon Technologies. It is designed for high-efficiency power management applications requiring low on-resistance and high current handling capability.

Key electrical specifications include a drain-source voltage (Vdss) of 30V, continuous drain current of 17A at 25°C ambient temperature (Ta) and 71A at 25°C case temperature (Tc), and a maximum Rds(on) of 5.3mOhm at Vgs=10V and Id=30A. The gate charge (Qg) is 29 nC at Vgs=10V, and input capacitance (Ciss) is 2700 pF at Vds=15V. The device operates over a junction temperature range of -40°C to 150°C.

The MOSFET is housed in a surface-mount 3-WDSON package (MG-WDSON-2, CanPAK M) and requires a drive voltage of 4.5V or 10V for optimal performance. It is suitable for applications such as DC-DC converters, power supplies, and motor control circuits where efficient switching and low conduction losses are critical.
