概述

Description

Pinout

Pin count: 3.
Function: NPN general‑purpose transistor (2N2222A family) used for switching and amplification.
Pinout (TO‑92, flat face toward you): Emitter (left) – Base (middle) – Collector (right).

Manufacturer

There isn’t a widely known part called PXT2222A. It may be a misprint for 2N2222A, a common NPN transistor produced by many vendors. A major manufacturer is ON Semiconductor (onsemi), an American multinational company that designs and manufactures semiconductors and discrete devices for automotive, industrial, and consumer markets.

Equivalent

Equivalents depend on the chip’s function and maker. “PXT2222A” isn’t enough to identify substitutes. Please share the datasheet/link or specify its role (MCU, op-amp, sensor, transceiver), voltage, package, and interface. With that, I can provide exact cross‑references from TI, Analog Devices, Microchip, NXP, Renesas, etc., and suitable substitutes with pinout and specs.
