< 500V Transistors  

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 include:

• 15 to 120 V BJTs based on the second generation of base island technology for improved V_CE(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 PowerFLAT™ 2 x 2 mm²
