Visão Geral

Description

BC856B is a PNP small‑signal transistor from the BC856 family, the complementary part to BC846 (NPN). The “B” gain group indicates mid/high current gain.
Key specs (typical, from datasheets):
- Vceo: 45 V
- Ic max: 100 mA
- Ptot: ~250 mW
- hFE: roughly 160–320 (group B) at standard test currents; exact range depends on lot and Ic
Package options include through‑hole TO‑92 and various SMD versions. It’s used for general switching and low‑power amplification in analog and digital circuits.
Common notes:
- Polarities: PNP device—emitter more positive than collector.
- Complement: BC846 (NPN).
- Always verify the exact variant’s datasheet for pinout and guaranteed limits for your package type.

Equivalent

BC856B (PNP small‑signal, Vceo ≈ −65V, Ic ≤100 mA) equivalents: the same BC856B from other manufacturers; BC857B (similar family, through‑hole variant); general substitutes if specs permit: 2N3906 / MMBT3906 (lower Vceo ≈40V) or other PNP small‑signal transistors. When substituting, match Vceo (≥65V), Ic, hFE and package/pinout.

Features

BC856B features (general points):
- PNP general-purpose transistor
- TO-92 through-hole package
- Vceo (max) about 45 V
- Ic max about 100 mA
- Ptot around 125 mW
- DC current gain hFE: group B (roughly 110–800, depending on Ic and Temp)
- Low-noise variant; complementary to BC846 (NPN)
- Suitable for general amplification and small-signal switching
- Temperature range typically −55 to +150 °C
Note: exact numbers vary by manufacturer; refer to the specific datasheet for your lot.

Pinout

BC856B,215 is a 3‑pin PNP general‑purpose transistor in an SOT‑23 package. Pins = Emitter, Base, Collector. Common SOT‑23 numbering is pin 1 = E, pin 2 = B, pin 3 = C, but verify the exact pinout on the manufacturer's datasheet.

Manufacturer

The BC856B,215 is manufactured by STMicroelectronics. STMicroelectronics is a multinational semiconductor company that designs, manufactures and sells integrated circuits and discrete semiconductor devices (analog, digital, mixed-signal, power devices and sensors) for consumer, industrial, automotive and communications markets.

Application

BC856B is a PNP general‑purpose transistor (215 grade denotes its gain group). Applications include:
- Small‑signal amplification and buffering
- Impedance matching and level shifting
- High‑side switching and driver stages in portable/consumer electronics
- Emitter‑follower buffers and signal routing
- Complement to BC846 (NPN) in push‑pull or differential pairs
- Relay/display/opto‑coupler driver circuits in low‑power designs
Note: each device is suitable for low to moderate current in general analogue/switching roles.

Package

The BC856B,215 is supplied in an SOT-23 (3‑lead) surface-mount package.
