Product details

650 V N-channel in a DPAK — switching supply workhorse

The STD65N160M9 is an STMicroelectronics N-channel power MOSFET from the MDmesh M9 series, built for high-voltage switching applications.

Rds(on) is specified at 160 mOhm maximum with 10 A drain current and 10 V gate drive — the 10 V drive voltage is the recommended rail for minimum on-resistance. At 17 A continuous drain current and 25°C case temperature, the conduction loss at full load is I²R = 46 W, which sits within the 106 W power dissipation rating at the case. Gate charge is 32 nC at 10 V. Input capacitance is 1239 pF at 400 V drain-source.

Frequently asked questions

What are the exact Rds(on) and Vgs(th) of STD65N160M9?

Rds(on) is 160 mOhm maximum at 10 A drain current and 10 V gate drive. The gate threshold voltage Vgs(th) is 4.2 V maximum at 250 µA drain current.

What is the closest pin-compatible alternative to STD65N160M9 in this component family?

The MDmesh M9 series includes multiple Rds(on) and current rating variants in the same DPAK footprint. The STD65N160M9 sits at the 160 mOhm tier; higher-current siblings in the same package share the same pinout and land pattern. No specific alternate order code is listed as a direct cross-reference.
