2P7154AC MOSFET — Specifications & Equivalents

About the 2P7154AC

The 2P7154AC is a MOSFET with a drain–source voltage (V_DS) rating of 1200 V and a continuous drain current (I_D) of 50 A. It can dissipate up to 875 W and is rated to a junction temperature of 150 °C.

At a glance

• Type: MOSFET
• Max drain–source voltage (V_DS): 1200 V
• Max continuous drain current (I_D): 50 A
• Power dissipation (P_D): 875 W
• Max junction temperature (T_J): 150 °C

Typical applications

With its 1200 V drain–source rating the 2P7154AC sits in the ultra-high-voltage class of switching MOSFETs, typically found in industrial ignition and igniter circuits, high-voltage pulse generators and electrostatic and CRT deflection stages. Ratings at this level demand careful creepage/clearance and insulation design on the PCB.

The 50 A current rating puts it in high-current territory, where conduction loss (I² × R_DS(on)) and thermal design usually matter more than switching loss. Budget for adequate copper area and a heatsink.

Gate drive and switching notes

Keep gate–source voltage within the ±25 V maximum; exceeding it punctures the gate oxide and destroys the device permanently.

Choosing a replacement for the 2P7154AC

A drop-in substitute for the 2P7154AC should match its polarity and offer a drain–source rating of at least 1200 V and a continuous drain current rating of at least 50 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 2P7154AC?

The 2P7154AC is a MOSFET (metal-oxide-semiconductor field-effect transistor). It is rated for 1200 V drain-source and 50 A continuous drain current.

What is the maximum voltage of the 2P7154AC?

The 2P7154AC has a maximum drain-source voltage (Vds) of 1200 V. Treat this as an absolute maximum and design with margin, especially when switching inductive loads.

How much current can the 2P7154AC handle?

It is rated for 50 A of continuous drain current, with power dissipation limited to 875 W. Real-world capability depends on your heatsinking and ambient temperature.

What can I use to replace the 2P7154AC?
