PMBT3906, PNP Switching Transistor, SOT-23

The PMBT3906 is a surface-mount PNP transistor designed for general-purpose switching and amplification. It is widely used in telecom and communication equipment. With a maximum collector current of 100 mA and a breakdown voltage of 40V, it balances performance and reliability in small signal circuits. It is housed in a SOT-23 plastic package optimized for automated assembly lines.

Key Features:

• PNP Switching Type: Ideal for low-voltage, low-current applications.
• Compact SOT-23 Package: Surface-mount design suitable for compact PCBs.
• Fast Switching Time: Rise/fall times as low as 35 ns and 75 ns respectively.
• Low Collector-Emitter Saturation Voltage: Max -200 mV at -50 mA for efficient operation.
• Low Noise Figure: 4 dB typical, suitable for analog signal applications.
• Complement to PMBT3904 (NPN): Used in complementary push-pull configurations.
