2P829V MOSFET — Specifications & Equivalents

About the 2P829V

The 2P829V is a MOSFET with a drain–source voltage (V_DS) rating of 600 V and a continuous drain current (I_D) of 20 A. It can dissipate up to 200 W and is rated to a junction temperature of 125 °C. It is supplied in the КТ-105-1 package.

Typical applications

With its 600 V drain–source rating the 2P829V sits in the high-voltage (offline) class of switching MOSFETs, typically found in primary-side switching in offline SMPS (flyback, forward and quasi-resonant), active PFC boost stages, half-bridge and full-bridge inverters, induction heating and electronic ballasts and BLDC and AC motor drives. The rating leaves usable margin above the ~325 V DC bus obtained by rectifying 230 VAC mains, which is why this class dominates offline power supplies.

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.

Switching behaviour is characterised by an output capacitance (C_oss) of 1100 pF, which together with the gate drive determines switching loss and the practical upper frequency limit.

Choosing a replacement for the 2P829V

A drop-in substitute for the 2P829V should match its polarity and offer a drain–source rating of at least 600 V and a continuous drain current rating of at least 20 A.

Mechanically, check the replacement against the КТ-105-1 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 2P829V?

The 2P829V is a MOSFET (metal-oxide-semiconductor field-effect transistor). It is rated for 600 V drain-source and 20 A continuous drain current.

What is the maximum voltage of the 2P829V?

The 2P829V has a maximum drain-source voltage (Vds) of 600 V. Treat this as an absolute maximum and design with margin, especially when switching inductive loads.

How much current can the 2P829V handle?

It is rated for 20 A of continuous drain current, with power dissipation limited to 200 W. Real-world capability depends on your heatsinking and ambient temperature.

What package does the 2P829V come in?

It is listed in КТ-105-1. Verify the pinout of the specific variant, as one outline can carry different pin assignments.

What can I use to replace the 2P829V?

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.
