Pinout
The STCA0603N9 is a N-channel MOSFET in a SOT-23 package with 3 pins:
1. Gate (G) – Controls the switching operation.
2. Drain (D) – Connects to the load (high-side terminal).
3. Source (S) – Connects to ground (low-side terminal).
Key features:
- 60V drain-source voltage (VDS)
- Low on-resistance (RDS(on)) for efficient switching
- Compact SOT-23 footprint
Commonly used in power switching, DC-DC converters, and load control applications.
