Description

The BC848B is a general-purpose NPN bipolar junction transistor (BJT) commonly used in amplification and switching applications. Key features include:
- Package: SOT-23 (small surface-mount)
- Voltage Ratings:
- Collector-Emitter (VCE): 30V
- Collector-Base (VCB): 30V
- Emitter-Base (VEB): 5V
- Current Ratings:
- Continuous Collector Current (IC): 100mA
- Peak Current (pulsed): 200mA
- Gain (hFE): 200–450 (at 2mA IC)
- Power Dissipation (Ptot): 250mW
Applications: Low-power amplifiers, signal processing, and switching circuits. It is part of the BC848 series, with the "B" suffix indicating medium current gain.
Alternatives: BC547B (similar specs, TO-92 package).
For precise use, consult the datasheet for thermal and electrical limits.

Pinout

The BC848B is a general-purpose NPN bipolar junction transistor (BJT) with 3 pins (TO-92 package):
1. Emitter (E) – Output for current flow.
2. Base (B) – Controls transistor switching/amplification.
3. Collector (C) – Receives current from the circuit.
Key Functions:
- Amplification: Boosts weak signals.
- Switching: On/off control for loads.
- Max Ratings: 30V (VCEO), 100mA (IC), 200mW (Ptot).
Common in low-power analog/digital circuits.

Package

The BC848B is a general-purpose NPN transistor available in a SOT-23 surface-mount package. This compact 3-pin package is widely used for small-signal amplification and switching applications. The SOT-23 is suitable for automated PCB assembly due to its small size (approx. 2.9 x 1.3 x 0.95 mm). Other variants (e.g., BC848) may share the same package.
