2P7209A MOSFET — Specifications & Equivalents
About the 2P7209A
The 2P7209A is a P-channel MOSFET with a drain–source voltage (VDS) rating of 100 V, a continuous drain current (ID) of 19 A and an on-resistance (RDS(on)) of 0.2 Ω. It can dissipate up to 150 W and is rated to a junction temperature of 125 °C. It is supplied in the KT97V package.

Typical applications
With its 100 V drain–source rating the 2P7209A 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 2P7209A
A drop-in substitute for the 2P7209A must be the same P-channel type and offer a drain–source rating of at least 100 V, a continuous drain current rating of at least 19 A and an on-resistance no higher than 0.2 Ω if efficiency and heat matter.
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 2P7209A?
The 2P7209A is a P-channel MOSFET (metal-oxide-semiconductor field-effect transistor). It is rated for 100 V drain-source and 19 A continuous drain current.
What is the maximum voltage of the 2P7209A?
The 2P7209A 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 2P7209A handle?
It is rated for 19 A of continuous drain current, with power dissipation limited to 150 W. Real-world capability depends on your heatsinking and ambient temperature.
What is the on-resistance of the 2P7209A?
On-resistance (Rds(on)) is 0.2 Ω. Multiply by the square of your load current to estimate conduction loss.
What package does the 2P7209A 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 2P7209A?
No verified equivalents are listed yet. Choose a part of the same polarity that meets or exceeds every rating above and shares a compatible package and pinout.
