ZXTP25100CFH bipolar transistor — Specifications & Equivalents

About the ZXTP25100CFH

The ZXTP25100CFH is a PNP bipolar transistor with a collector–emitter voltage (V_CEO) rating of 100 V, a continuous collector current (I_C) of 1 A and a DC current gain (h_FE) of minimum 180. It can dissipate up to 1.25 W. It is supplied in the SOT23 package.

Typical applications

Judging from its ratings the ZXTP25100CFH is generally applied in RF and high-speed switching stages.

A transition frequency (f_T) of 180 MHz indicates the frequency range over which useful current gain remains available.

The quoted current gain of minimum 180 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 100 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 1.25 W, and that figure assumes the datasheet's mounting and ambient conditions — derate it for your own thermal design.

Choosing a replacement for the ZXTP25100CFH

A drop-in substitute for the ZXTP25100CFH must be the same PNP type and offer a collector–emitter rating of at least 100 V, a collector current rating of at least 1 A, current gain in the same ballpark as minimum 180 and a transition frequency of at least 180 MHz for the same bandwidth.

Mechanically, check the replacement against the SOT23 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 ZXTP25100CFH?

The ZXTP25100CFH is a PNP bipolar junction transistor (BJT). It is rated for 100 V collector-emitter and 1 A continuous collector current.

What is the maximum voltage of the ZXTP25100CFH?

Maximum collector-emitter voltage (Vceo) is 100 V.

How much current can the ZXTP25100CFH handle?

Continuous collector current is rated at 1 A, with dissipation limited to 1.25 W.

What is the hFE of the ZXTP25100CFH?

DC current gain (hFE) is quoted as minimum 180. Size base drive from the minimum value so the transistor saturates fully across production spread.

What package does the ZXTP25100CFH come in?

It is listed in SOT23. Verify the pinout of the specific variant, as one outline can carry different pin assignments.

What can I use to replace the ZXTP25100CFH?

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.
