Pinout
1. Emitter (E) – Connected to the ground or lower voltage.
2. Base (B) – Controls the transistor’s switching/amplification.
3. Collector (C) – Connects to the load or higher voltage.
Key Features:
- Low power (max 250mA collector current, 300mW power dissipation).
- High current gain (hFE) – Typically 200-450.
- Used in switching, amplification, and signal processing circuits.
Compact and widely used in SMD applications.
