STW46NF30 Description

The STW46NF30 from STMicroelectronics is a high-performance N-channel MOSFET designed for demanding power management applications. Built using advanced STripFET™ II technology, it offers a robust 300V drain-to-source voltage (Vdss) rating and a continuous drain current (Id) of 42A (Tc) at 25°C. With a low on-resistance (Rds(on)) of 75mOhm at 17A, 10V, this device minimizes conduction losses, enhancing efficiency in high-power circuits. The MOSFET operates reliably up to 175°C junction temperature (TJ) and features a ±20V gate-to-source voltage (Vgs) tolerance, ensuring durability in harsh environments. Packaged in a TO-247 through-hole format, it is ideal for applications requiring high thermal dissipation.

STW46NF30 Features

• Low Rds(on): 75mOhm @ 17A, 10V reduces power losses and improves efficiency.
• High Voltage Rating: 300V Vdss for robust performance in high-voltage circuits.
• Fast Switching: Optimized gate charge (Qg) of 90nC @ 10V and input capacitance (Ciss) of 3200pF @ 25V ensure efficient switching performance.
• Thermal Performance: 300W (Tc) power dissipation and TO-247 package enhance heat management.
• Reliability: ROHS3 compliant, REACH unaffected, and MSL 1 (Unlimited) for long-term stability.
• Wide Operating Range: -55°C to 175°C TJ for versatile industrial use.
