Product details

Obsolete part — sourcing from independent distribution

Key ratings for power-switching fit

This N-channel MOSFET from the DeepGATE™ and STripFET™ series is rated for a drain-to-source voltage of 100 V and a continuous drain current of 65 A at 25°C case temperature. These ratings suit it for high-current switching in DC-DC converters, motor drives, and power supply output stages where board space is less constrained — the TO-220 through-hole package handles the thermal dissipation with a 150 W power dissipation capability.

Temperature range and gate drive requirements

The gate threshold voltage is specified at 4 V maximum at 250 µA drain current, and the recommended drive voltage for minimum on-resistance is 10 V. Gate charge is 85 nC at 10 V, and input capacitance is 5800 pF at 25 V drain-source — both figures to budget in the gate driver design for switching losses.

Frequently asked questions

Where can I buy STP70N10F4 available via RFQ confirmation?

Submit an RFQ to confirm current availability and pricing — stock is quoted to order, not listed on a public shelf.

What is the replacement for STP70N10F4?

The evidence does not list an official STMicroelectronics replacement or successor order code. For a pin-compatible alternative in the same TO-220 package, cross-reference parts from the STP70N series with similar 100 V, 65 A, and Rds(on) ratings — verify the gate charge and threshold voltage against your drive circuit before substituting.
