ALLNET ALL-BRICK-0005 Transistor Module NPN BJT for Arduino Raspberry Pi

The ALLNET ALL-BRICK-0005 is a compact NPN bipolar junction transistor (BJT) module designed for digital switching and signal amplification in microcontroller projects. It features a single TO-92 packaged transistor with a maximum collector-emitter voltage of 40 V and collector current of 100 mA, making it ideal for driving LEDs, small DC motors, relays, and logic level shifting. The module operates at 3.3V-5V DC and includes a 3-pin header (VCC, GND, Signal) for easy integration with Arduino, Raspberry Pi, and other microcontrollers.

Advantages

This transistor module simplifies prototyping by providing a ready-to-use interface with an open-collector output. Its high DC current gain (hFE 100-800) ensures efficient signal amplification, while the compact design saves space on breadboards or PCBs. Compatible with both 3.3V and 5V logic levels, it offers flexibility for various projects.

Suitable for

• Driving LEDs and small DC motors
