STQ1NC45R-AP Description

Short technical summary and product information.

The STQ1NC45R-AP is an N-Channel Power MOSFET from STMicroelectronics, part of the SuperMESH™ series. It is designed for high voltage applications with a drain-source voltage (Vds) of 450V and a continuous drain current of 500mA (Tc=25°C).

 

Key electrical characteristics include a maximum on-resistance (Rds On) of 4.5 Ohms at 500mA and 10V gate-source voltage, and a gate charge (Qg) of 7nC at 10V. The device also features a gate-source voltage range of ±30V and a threshold voltage (Vgs(th)) of 3.7V at 250µA.

 

This MOSFET is suitable for switching applications such as switch mode low power supplies, low power CFLs, and low power battery chargers. It is packaged in a TO-92-3 (TO-226-3) through-hole package, with a maximum power dissipation of 3.1W (Tc=25°C) and an operating temperature range of -65°C to 150°C.

 

The SuperMESH™ series offers extremely high dv/dt capability and is 100% avalanche tested, making it a reliable choice for demanding applications.
