S8050 NPN Transistor Truth Table
| Base (B) | Collector (C) | Emitter (E) | Transistor State | Collector-Emitter Current |
|---|---|---|---|---|
| LOW | HIGH | LOW | OFF (Cutoff) | 0 |
| HIGH | HIGH | LOW | ON (Saturation) | Flows (ON) |
Notes:
- Base HIGH: A small current applied to the base (typically >0.7V above emitter) turns the transistor ON, allowing current to flow from collector to emitter.
- Base LOW: No base current keeps the transistor OFF, and no current flows from collector to emitter.
- Collector is usually connected to a positive voltage, emitter to ground.
