Présentation

Description

The BC857BS is a PNP bipolar junction transistor (BJT) in a SOT-363 (SC-88) surface-mount package, designed for general-purpose amplification and switching applications.
### Key Features:
- Type: PNP
- Voltage (VCEO): -45V
- Current (IC): -100mA
- Power Dissipation (Ptot): 250mW
- Gain (hFE): 110–800 (depending on variant)
- Package: SOT-363 (dual-emitter configuration)
### Applications:
- Low-power amplification
- Signal switching
- Audio circuits
- Driver stages
### Advantages:
- Small footprint
- High current gain
- Low noise
### Alternatives:
- BC856BS (lower VCEO)
- 2N3906 (through-hole equivalent)
Ideal for compact, low-voltage designs. Check datasheet for exact specifications.

Equivalent

The BC857BS is a PNP general-purpose transistor in SOT-363 package. Equivalent alternatives include:
- BC857S (same specs, different package marking)
