概述
Description
BC847BPN-QX is a general‑purpose small‑signal NPN transistor in an SOT‑23 package. It belongs to the BC847 family and is used for low‑power amplification and switching in compact, surface‑mount designs.
Key points:
- Package and pinout: SOT‑23, 3 leads. Pin order (front view): 1 = Emitter, 2 = Base, 3 = Collector (verify with datasheet orientation).
- Electricals (typical for grade B): Vceo ≈ 45 V; Ic up to 100 mA; hFE (gain) in the roughly 200–450 range, depending on Ic and temperature.
- Characteristics: low noise for a small transistor; suitable for signal amplification, sensor interfaces, and light switching.
- Suffix meaning: -QX denotes RoHS/compliant Pb‑free packaging with a specific tape/reel code; -PN reflects the manufacturer’s Pb‑free leadframe/packaging variant for this part.
In short: a compact, hobby/field‑friendly NPN transistor for general purpose, with decent gain and a 45 V rating, in a widely used SOT‑23 format.
