2P7172A MOSFET — Specifications & Equivalents

About the 2P7172A

The 2P7172A is a MOSFET with a drain–source voltage (V_DS) rating of 100 V and a continuous drain current (I_D) of 30 A. It can dissipate up to 125 W and is rated to a junction temperature of 125 °C. It is supplied in the KT97V package.

At a glance

• Type: MOSFET
• Max drain–source voltage (V_DS): 100 V
• Max continuous drain current (I_D): 30 A
• Power dissipation (P_D): 125 W

Typical applications

With its 100 V drain–source rating the 2P7172A sits in the medium-voltage class of switching MOSFETs, typically found in 48 V and 96 V distribution systems, solar and telecom power stages, DC motor drives and intermediate-bus DC-DC converters.

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.

Choosing a replacement for the 2P7172A

A drop-in substitute for the 2P7172A should match its polarity and offer a drain–source rating of at least 100 V and a continuous drain current rating of at least 30 A.

Mechanically, check the replacement against the KT97V 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 2P7172A?

The 2P7172A is a MOSFET (metal-oxide-semiconductor field-effect transistor). It is rated for 100 V drain-source and 30 A continuous drain current.

What is the maximum voltage of the 2P7172A?

The 2P7172A has a maximum drain-source voltage (Vds) of 100 V. Treat this as an absolute maximum and design with margin, especially when switching inductive loads.

How much current can the 2P7172A handle?

It is rated for 30 A of continuous drain current, with power dissipation limited to 125 W. Real-world capability depends on your heatsinking and ambient temperature.

What package does the 2P7172A come in?

It is listed in KT97V. Verify the pinout of the specific variant, as one outline can carry different pin assignments.

What can I use to replace the 2P7172A?

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.
