BC817BPN-AQ | Complementary NPN and PNP Transistors in One Compact Package

Diotec Semiconductor, with its headquarters in Germany, expands its bipolar transistor portfolio with the BC817BPN-AQ, integrating an NPN and a PNP transistor into a single SOT-26 package. The device offers a compact solution for automotive and industrial circuit designs.

In electronic circuits requiring both NPN and PNP transistors, designers traditionally rely on two separate components. Combining both transistor polarities in one package, the BC817BPN-AQ, helps engineers to optimize the PCB space by reducing the component count.

The complementary transistor configuration is particularly suitable for applications involving bidirectional current control and signal amplification. The NPN and PNP transistors provide complementary switching functions, making the device suitable for motor control stages and amplifier circuits that process both positive and negative signal excursions.

Key Technical Features

  • Complementary NPN and PNP bipolar transistors in one packageCollector-emitter voltage rating: 45 V

  • Collector current rating: 500 mA

  • Compact SOT-26 package

  • AEC-Q101 qualified for automotive applications

For design engineers, the BC817BPN-AQ can simplify component placement in push-pull amplifiers, signal processing applications and gate driver circuits.

With the BC817BPN-AQ, Diotec Semiconductor continues to develop compact semiconductor solutions for automotive and industrial electronics, addressing the demand for efficient circuit integration and space-saving component designs.
