概述

Description

BC846B-QR is a surface-mount, general‑purpose NPN transistor in the SOT‑23 package. It’s part of the BC846/BC856 family; the “B” indicates the gain group (higher hFE than A, lower than C). The “QR” suffix typically denotes Tape & Reel packaging for automated assembly.
Key specs (typical): Vceo ≈ 45 V; Ic max ≈ 100 mA; hFE in the B group (roughly 200–450 at Ic ≈ 2 mA, temperature dependent). It’s a low‑noise, small‑signal device with good high‑frequency performance (fT in the hundreds of MHz range).
Common uses: general small‑signal amplification, switching, buffering in power‑/signal‑sensitive circuits, audio front‑ends, sensor interfacing, and other low‑to‑medium current applications.
Note: exact electrical limits and pinout can vary by vendor and lot. For precise values, consult the specific BC846B‑QR datasheet from the supplier.
