概述

Description

BCP56T-QX is a surface‑mount NPN bipolar transistor in the BCP56 family, used for general medium‑power switching and amplification.
Key points:
- NPN BJT suitable for medium power switching and small signal amplification.
- Typical ratings (varies by package/revision): Vce around 60 V; Ic on the order of about 1 A; hFE depends on Ic (tens to hundreds); Vce(sat) a few tenths of a volt under proper base drive.
- Package “T‑QX” denotes a specific SMT package variant; exact pinout and dissipation depend on the supplier’s datasheet.
- Common usage: drive a load from a higher supply using a base resistor (Ib ≈ Ic/hFE), with the emittered tied to ground (or reference), and appropriate base/collector wiring for switching or amplification.
- Selection tips: check the exact datasheet for pinout, maximum ratings, power dissipation, and thermal considerations; ensure the package can handle the intended Ic and dissipation in your board layout.
For precise specs and pinout, consult the supplier’s BCP56T-QX datasheet.

Features
