ZXTP722MA bipolar transistor — Specifications & Equivalents

About the ZXTP722MA

The ZXTP722MA is a PNP bipolar transistor with a collector–emitter voltage (V_CEO) rating of 70 V, a continuous collector current (I_C) of 2.5 A and a DC current gain (h_FE) of minimum 300. It can dissipate up to 1.5 W. It is supplied in the U-DFN2020 package.

• Package: U-DFN2020

Typical applications

Judging from its ratings the ZXTP722MA is generally applied in RF and high-speed switching stages.

A transition frequency (f_T) of 150 MHz indicates the frequency range over which useful current gain remains available.

The quoted current gain of minimum 300 determines the base drive needed: divide your target collector current by the minimum h_FE, not the typical figure, when sizing the base resistor.

Biasing and absolute maximum ratings

Absolute-maximum breakdown limits are V_CEO 70 V (magnitudes). The emitter–base rating is the easiest to overlook and is often only a few volts, so protect the junction against reverse drive.

Dissipation is capped at 1.5 W, and that figure assumes the datasheet's mounting and ambient conditions — derate it for your own thermal design.

Choosing a replacement for the ZXTP722MA

A drop-in substitute for the ZXTP722MA must be the same PNP type and offer a collector–emitter rating of at least 70 V, a collector current rating of at least 2.5 A, current gain in the same ballpark as minimum 300 and a transition frequency of at least 150 MHz for the same bandwidth.

Mechanically, check the replacement against the U-DFN2020 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 ZXTP722MA?

The ZXTP722MA is a PNP bipolar junction transistor (BJT). It is rated for 70 V collector-emitter and 2.5 A continuous collector current.

What is the maximum voltage of the ZXTP722MA?

Maximum collector-emitter voltage (Vceo) is 70 V.

How much current can the ZXTP722MA handle?

Continuous collector current is rated at 2.5 A, with dissipation limited to 1.5 W.

What is the hFE of the ZXTP722MA?

DC current gain (hFE) is quoted as minimum 300. Size base drive from the minimum value so the transistor saturates fully across production spread.

What package does the ZXTP722MA come in?

It is listed in U-DFN2020. Verify the pinout of the specific variant, as one outline can carry different pin assignments.

What can I use to replace the ZXTP722MA?

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.
