ST's power bipolar transistors with a voltage rating up to 500 V are available with both NPN and PNP polarity. We offer both industry-standard and proprietary devices.
Key features of our NPN and PNP transistors (< 500 V)
- 15 to 120 V BJTs based on the second generation of base island technology for improved VCE(sat) and gain
- 150 to 300 V dedicated parts featuring excellent gain linearity and pair matching for professional class AB audio amplifiers
- Very high gain characteristic for reduced driving requirements
- Very low saturation voltage to minimize conduction losses
- High switching speed
- Wide portfolio of miniaturized SMD packages including the latest PowerFLATâ„¢ 2 x 2 mm2
Our power bipolar transistor portfolio also includes high voltage and > 1000 V NPN-PNP transistors.
