概述

Description

BC846BMB,315 refers to a BC846B NPN small-signal transistor in a SOT-23 package, with “BMB” as the package/marking code and “315” likely a lot/date code. It is a general-purpose transistor used for switching and low-noise amplification in compact circuits.
Typical specs (varies by vendor):
- Type: NPN bipolar transistor
- Vceo: about 45 V
- Ic: up to ~100 mA
- hFE: in the B gain group (roughly 200–450 at test conditions; varies with Ic and temperature)
- Noise: low for audio/small-signal applications
Common applications:
- Small-signal amplification
- General switching, LED driver, sensor interfacing
Notes:
- Pinout (which pin is B, C, E) depends on the manufacturer and datasheet. Always verify from the specific device datasheet.
- Ensure proper biasing and respect maximum power dissipation at your operating temperature.

Features

BC846BMB,315 features (highlights)
- NPN general‑purpose small‑signal transistor
- Package: SOT‑23 (3 pins), Pb‑free; code MB (tape & reel variants)
- max Ic: 100 mA
- Vceo: up to 45 V
- Gain (hFE): group B (typical ~200–450 at Ic = 2 mA)
- Low noise for small‑signal amplification
- Wide temp range: typically −55 °C to +150 °C
- Applications: amplification, switching in compact SMT designs
- RoHS compliant and suitable for surface‑mount assembly
Note: exact hFE and packaging variant can vary by lot; check the datasheet for your lot code (315).

Package

The BC846BMB,315 is supplied in a 3‑lead SOT‑23 (SC‑59) surface‑mount package, typically delivered on tape-and-reel.

Pinout

- Pin count: 3 pins (SOT-23 package)
- Function: NPN general-purpose small-signal transistor (used for switching or amplification). The 315 is just a date/lot code and does not change the function.
