Product details

100 V, 9.7 A N-channel switch in TO-220

The IRF520NPBF: The TO-220-3 through-hole package keeps the part board-mountable with a single screw tab for heatsinking.

Gate drive and switching budget

The gate threshold is specified at 4 V maximum with 250 µA drain current, but the Rds(on) is characterised at 10 V drive — this is not a logic-level FET.

Thermal and environmental reach

That 175°C ceiling suits environments where the heatsink is marginal or the ambient runs hot — motor drives in enclosures, engine-bay auxiliaries, or power supplies with constrained airflow. Maximum power dissipation is 48 W at the case, but derating above 25°C is aggressive; a real design budgets for the thermal resistance of the heatsink interface.

Frequently asked questions

Is IRF520NPBF compatible with standard IRF520?

The IRF520NPBF is the lead-free, ROHS3-compliant version of the standard IRF520. Electrical ratings — 100 V Vdss, 9.7 A continuous drain, 200 mOhm Rds(on) — are identical to the original IRF520 specification. The NPBF suffix indicates the green, halogen-free plating; pinout and footprint are the same TO-220AB.

Does IRF520NPBF have a logic-level gate threshold?

No. The maximum gate threshold voltage is 4 V at 250 µA drain current, and the on-resistance is specified at 10 V gate drive.
