Product details

Gate charge and switching speed

Total gate charge is 30 nC at 10 V. For a hard-switched converter at 100 kHz, the average gate-drive current is 3 mA — well within a standard driver's capability. The 1150 pF input capacitance at 50 V drain-source means the driver sees a moderate capacitive load; rise and fall times are dominated by the driver's peak current capability, not the FET's Ciss.

175°C junction — extended temperature margin

The 4 V maximum gate threshold at 50 µA drain current is typical for standard-threshold logic-level FETs — the 10 V drive voltage for minimum Rds(on) is the normal operating point.

DPak (TO-252) — surface-mount power layout

The DPak (TO-252) package has three leads plus a drain tab. The tab is the primary thermal path — the PCB copper area under it sets the junction-to-ambient thermal resistance. A 1-inch-square copper pad on a 2-oz board keeps the junction below 125°C at 25 A continuous in still air.

Frequently asked questions

What is the IRFR3806TRPBF equivalent or replacement?

No direct replacement or second-source is listed in the official records. The IPD50R950CEAUMA1 is a CoolMOS CE part with 500 V drain-source and 950 mOhm Rds(on) — it is a different voltage and on-resistance class and is not a functional substitute.
