2P7145B-5-IM MOSFET — Specifications & Equivalents

About the 2P7145B-5-IM

The 2P7145B-5-IM is a MOSFET with a drain–source voltage (V_DS) rating of 200 V and a continuous drain current (I_D) of 26 A. It can dissipate up to 150 W.

At a glance

• Type: MOSFET
• Max drain–source voltage (V_DS): 200 V
• Max continuous drain current (I_D): 26 A
• Power dissipation (P_D): 150 W

Typical applications

With its 200 V drain–source rating the 2P7145B-5-IM 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.

Choosing a replacement for the 2P7145B-5-IM

A drop-in substitute for the 2P7145B-5-IM should match its polarity and offer a drain–source rating of at least 200 V and a continuous drain current rating of at least 26 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 2P7145B-5-IM?

The 2P7145B-5-IM is a MOSFET (metal-oxide-semiconductor field-effect transistor). It is rated for 200 V drain-source and 26 A continuous drain current.

What is the maximum voltage of the 2P7145B-5-IM?

The 2P7145B-5-IM 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 2P7145B-5-IM handle?

It is rated for 26 A of continuous drain current, with power dissipation limited to 150 W. Real-world capability depends on your heatsinking and ambient temperature.
