Product details

40 V, 120 A N-Channel Power MOSFET in TO-220

The 40 V Vdss rating places this part in the low-voltage MOSFET class, suitable for 12 V or 24 V bus systems where margin against transients is needed. The 120 A continuous current rating is at a case temperature of 25°C; real-world derating applies as the junction warms up, and the 150 W power dissipation ceiling (at Tc=25°C) sets the thermal budget for the heatsink. Gate drive voltage is specified at 5 V and 10 V for achieving the minimum and maximum Rds(on). With a gate charge of 181 nC at 10 V, the driver must supply enough peak current for fast switching without excessive switching losses. The TO-220 package with through-hole mounting suits designs where heatsinking through the tab is straightforward.

Frequently asked questions

What is a direct replacement for STP160N4LF6?

No official direct replacement or cross-reference part number is listed by STMicroelectronics for STP160N4LF6. A functionally similar N-channel MOSFET with 40 V Vdss, 120 A Id, and TO-220 package would need to be evaluated for Rds(on), gate charge, and thermal performance to confirm fit.
