Typical applications
With its 200 V drain–source rating the 2P7145B-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-IM
A drop-in substitute for the 2P7145B-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.
Mechanically, check the replacement against the KT9 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 2P7145B-IM?
The 2P7145B-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-IM?
The 2P7145B-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-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.
What package does the 2P7145B-IM come in?
It is listed in KT9. Verify the pinout of the specific variant, as one outline can carry different pin assignments.
What can I use to replace the 2P7145B-IM?
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.
