IRF630MFP MOSFET — Specifications & Equivalents

About the IRF630MFP

The IRF630MFP is a MOSFET with a drain–source voltage (V_DS) rating of 200 V and a continuous drain current (I_D) of 9 A. It can dissipate up to 30 W and is rated to a junction temperature of 150 °C. It is supplied in the TO220FP package.

Typical applications

With its 200 V drain–source rating the IRF630MFP sits in the medium-high-voltage class of switching MOSFETs, typically found in telecom and industrial DC rails, boost and flyback converters, LED and backlight drivers and power-factor-correction stages. Common where the bus sits well above 100 V but below rectified mains.

Gate drive and switching notes

Keep gate–source voltage within the ±20 V maximum; exceeding it punctures the gate oxide and destroys the device permanently.

Switching behaviour is characterised by an output capacitance (C_oss) of 120 pF, which together with the gate drive determines switching loss and the practical upper frequency limit.

Choosing a replacement for the IRF630MFP

A drop-in substitute for the IRF630MFP should match its polarity and offer a drain–source rating of at least 200 V and a continuous drain current rating of at least 9 A.

Mechanically, check the replacement against the TO220FP footprint and confirm the pin order — parts sharing a package outline do not always share a pinout.

Where the application switches inductive loads or runs near the voltage limit, keep extra headroom rather than choosing a part that only just meets the original numbers.

Frequently asked questions

What is the IRF630MFP?

The IRF630MFP is a MOSFET (metal-oxide-semiconductor field-effect transistor). It is rated for 200 V drain-source and 9 A continuous drain current.

What is the maximum voltage of the IRF630MFP?

The IRF630MFP has a maximum drain-source voltage (Vds) of 200 V. Treat this as an absolute maximum and design with margin, especially when switching inductive loads.

How much current can the IRF630MFP handle?

It is rated for 9 A of continuous drain current, with power dissipation limited to 30 W. Real-world capability depends on your heatsinking and ambient temperature.

What package does the IRF630MFP come in?

It is listed in TO220FP. Verify the pinout of the specific variant, as one outline can carry different pin assignments.

What can I use to replace the IRF630MFP?

This page lists 17 candidate equivalents matched on electrical ratings and package. Any replacement should meet or exceed the original voltage, current and dissipation figures and use a compatible drive level.
