BCR22PN

Overview

The Diotec Semiconductor BCR22PN is an SMD digital transistor featuring two complementary NPN and PNP transistors in a single SOT-363 package. It integrates bias resistors with typical values of 22 kΩ for both R1 and R2, yielding a resistance ratio of 1. The device supports a maximum collector current (IC) of 100 mA and offers a minimum DC current gain (hFE) of 50 at VCE = 5 V and IC = 5 mA. Rated for a collector-emitter voltage (VCEO) of 60 V, it dissipates up to 200 mW of power. Operating temperatures range from -55°C to +150°C.

Feature Summary

• Integrates two complementary transistors with built-in bias resistor combinations within one compact package
• Designed for digital control applications including switching and signal processing
• Available in AEC-Q101 compliant (-Q suffix) and qualified (-AQ suffix) grades for automotive use

Applications

• Digital controls
• Switching circuits
• Signal processing

Procurement Notes

Verify the specific ordering suffix when purchasing. The standard version lacks automotive qualification, while the -Q suffix indicates compliance and the -AQ suffix indicates full qualification under AEC-Q101 standards. Confirm that the required VCEO rating of 60 V aligns with the BCR22PN variant, as other models in this series may be rated for 50 V.

Selection Notes

Select the BCR22PN when a balanced resistance ratio of 1:1 is required for driving complementary loads. Ensure the design accommodates the 200 mW power dissipation limit mounted on a PCB with 3 mm² copper pads per terminal. Verify that the 60 V collector-emitter voltage rating meets the circuit requirements, distinguishing it from the 50 V variants available in the same product family.

Part Context

The BCR22PN belongs to the Diotec BCRxPN series of SMD digital transistors. This series consolidates discrete transistors and bias resistors into small surface-mount packages like SOT-363. The BCR22PN specifically provides equal input resistances for both the NPN and PNP channels, differentiating it from other series members such as the BCR08PN or BCR47PN which offer different resistance configurations.

Replacement Considerations

Direct substitutes include other BCR22PN units from Diotec. Cross-manufacturer replacements must match the SOT-363 footprint, 60 V VCEO rating, 100 mA IC, and integrated 22 kΩ / 22 kΩ resistor network.
