2P7172A-5 MOSFET — Specifications & Equivalents

About the 2P7172A-5

The 2P7172A-5 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.

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-5 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-5

A drop-in substitute for the 2P7172A-5 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.

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-5?

The 2P7172A-5 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-5?

The 2P7172A-5 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-5 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 can I use to replace the 2P7172A-5?

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.
