Pinout
The MMBT5401 is a PNP bipolar junction transistor (BJT) in a SOT-23 package.
Pin Count: 3
Pin Functions:
1. Emitter (E): Connected to the P-doped region, typically tied to the higher voltage in circuits.
2. Base (B): Controls the transistor's conduction; a small current here switches the larger collector-emitter current.
3. Collector (C): Connected to the N-doped region, usually the output or load side.
Key Features:
- General-purpose amplification/switching.
- Low power, high current gain (hFE).
- Max ratings: VCEO = -150V, IC = -600mA.
Wiring must match the datasheet pinout (E-B-C or other variants). Check manufacturer specs for exact configuration.
