M28S NPN Bipolar Transistor SOT-23
M28S is an NPN bipolar junction transistor in SOT-23 surface‑mount package. It features high current gain, medium current capability, and low saturation voltage, designed for general‑purpose amplification and switching in consumer electronics and industrial control circuits. With a maximum collector current of 1A and power dissipation of 0.625W, it provides reliable performance in space‑constrained designs.
Our Advantages
- Ultra-high DC current gain up to 1000 for high-sensitivity driving
- 1A continuous collector current for medium-power applications
- Compact SOT-23 package for high-density PCB assembly
- Excellent power dissipation up to 0.625W
- Stable electrical performance over wide temperature range
- Marking: 28S, easy for identification and use
- Tape-and-reel packaging suitable for automated SMT production
