STWA40N95DK5

STWA40N95DK5 Description

The STWA40N95DK5 from STMicroelectronics is a high-performance N-channel MOSFET designed for demanding power applications. Built using advanced MDmesh™ DK5 technology, it offers a robust 950V drain-to-source voltage (Vdss) rating and a continuous drain current (Id) of 38A at 25°C (case temperature). With an ultra-low on-resistance (Rds(on)) of 130mΩ at 10V gate drive, this device minimizes conduction losses, improving efficiency in high-power circuits. The TO-247 through-hole package ensures reliable thermal dissipation, supporting a maximum power dissipation of 450W (Tc).

STWA40N95DK5 Features

• High Voltage & Current Handling: 950V Vdss and 38A Id make it ideal for industrial and automotive applications.
• Low Rds(on): 130mΩ @ 10V reduces power losses, enhancing efficiency.
• Fast Switching: Optimized gate charge (Qg = 100nC @ 10V) and input capacitance (Ciss = 3480pF @ 100V) ensure minimal switching delays.
• Robust Construction: ±30V maximum gate-source voltage (Vgs) and TO-247 package provide durability and thermal stability.
• Compliance: ROHS3 and REACH compliant, with MSL 1 (unlimited) moisture sensitivity for extended shelf life.
