概述

Description

BC846A is a general‑purpose NPN transistor in a SOT-23 package, part of the BC846/BC847 family. It is a low‑noise, small‑signal device suitable for switching and amplification in compact circuits.
Key specs (typical): Ic up to 100 mA, Vceo about 65 V, Ptot ~ 250 mW. Gain groups differ: A ≈ 110–220 hFE, B ≈ 200–450, C ≈ 420–800. So A has the lowest gain and C the highest.
Common uses: signal amplification, switching, buffering, and biasing in radios, sensors, and other general‑purpose analog/digital circuits. It’s the surface‑mount counterpart of the through‑hole 2N3904/2N2222 family; suitable substitutes include MMBT3904 variants.
Note: “BC846A,215” isn’t a standard part number. The BC846 family uses gain group letters (A/B/C). If you meant a different part, please specify.

Features

BC846A is a general‑purpose, NPN silicon small-signal transistor. Key features:
- Package: SOT‑23 (SMT)
- Ic max: 100 mA
- Vceo: 45 V
- Vebo: 5 V; Vcbo: ~60 V
- DC gain (hFE) ranges by grade: A ≈ 110–220, B ≈ 200–450, C ≈ 420–800
- Low-noise, suitable for small-signal amplification
- Complement: BC856 (PNP)
- Temperature range: typically −55 to +150 °C
- Applications: general amplification and switching, audio/low-noise precursors, signal conditioning
Notes: BC846A is the A-gain variant of the BC846 family, with variants B/C offering higher gain.

Package

Do you mean the BC846A with the “,215” vendor suffix (different manufacturers use that)? Please provide the manufacturer or a datasheet link so I can confirm the exact package (SOT‑23, TO‑92, etc.).

Pinout

Pin count: 3 (SOT‑23 package).
Function: NPN silicon small‑signal transistor for switching and amplification (general‑purpose). The three pins are Base, Collector and Emitter — consult the manufacturer datasheet for the exact pin‑number to function mapping and package/packing details (",215" is a packing code).

Manufacturer

The BC846A,215 is sold by Diodes Incorporated. Diodes Incorporated is a global semiconductor company that designs and supplies discrete, analog and mixed-signal ICs (including diodes, transistors, rectifiers, MOSFETs and related components) for consumer, computing, industrial and communications markets.

Application

- BC846A: NPN general-purpose, low-noise small-signal transistor. Applications: small-signal amplification and buffering, signal conditioning, switching loads, audio preamps, sensor interfaces, level shifters, and driver stages for TTL/CMOS.
- BC215: PNP general-purpose small-signal transistor (complement to BC214). Applications: similar roles as BC214—high-side switching, biasing networks, emitter-follower stages, and small-signal amplification in audio/instrumentation and differential/push-pull stages.

Equivalent

BC846A (SOT‑23 NPN, low‑noise/general‑purpose, hFE group A) equivalents include: BC847A (SOT‑23, similar ratings), MMBT3904 (SMD 2N3904), 2N3904 / MMBT3904 family, BC547A (through‑hole equivalent). Also BC846 (other hFE groups) and BC848A are close. Verify Vce, Ic, hFE and package in datasheets before replacing.
