概述
Description
BCM847BS is a small‑signal NPN transistor (Broadcom/BCM family) used for general switching and amplification in surface‑mount designs. It’s typically offered in an SMD package (often SOT‑23 or similar) and rated for around 45 V Vce and about 100 mA Ic, with a wide, temperature‑dependent gain (hFE) suitable for many logic‑level and signal‑processing tasks. Commonly used for switching, level shifting, and small‑signal amplification in compact electronics.
Note: exact specs (max Ic, Vce, hFE, and pinout) vary by manufacturer and package variant labeled “BS.” Always consult the specific datasheet for the exact part you have (or share a link) to get precise figures and pin assignments.
