2N3904S-RTK/PS

The 2N3904S-RTK/PS is a variant of the popular NPN bipolar junction transistor (BJT) 2N3904, optimized for surface-mount (SMD) applications. Key features include:
- Package: SOT-23 (small, space-efficient).
- Applications: Switching and amplification in low-power circuits (e.g., signal processing, drivers).
- Ratings:
- V_CEO: 40V (max collector-emitter voltage).
- I_C: 200mA (max collector current).
- P_tot: 350mW (max power dissipation).
- Gain (h_FE): 100–300 (typical at 10mA).
The "RTK/PS" suffix may denote tape-and-reel packaging (RTK) or specific manufacturer branding. It’s compatible with standard 2N3904 pinouts (Emitter-Base-Collector in SOT-23).
Use cases: Consumer electronics, embedded systems, and portable devices requiring compact, reliable switching. Always check the datasheet for exact specifications.
