BC847PN

Overview

The BC847PN is a surface-mount general-purpose complementary NPN and PNP bipolar junction transistor array manufactured by Diotec Semiconductor. It is housed in an SOT-363 package containing two internally isolated transistors. The device supports a maximum DC collector current of 100 mA per transistor and offers a peak collector current of 200 mA. The power dissipation rating is 250 mW when mounted on a PCB with 3 mm² copper pads per terminal, or 200 mW with minimum pad layouts. The collector-emitter breakdown voltage is 45 V for the NPN transistor and 65 V for the PNP variant. The DC current gain ranges from 200 to 450 at 2 mA, with a transition frequency of 100 MHz.

Feature Summary

• Contains two complementary transistors (NPN and PNP) within a single compact package
• Designed for universal signal processing, switching, and amplification applications
• Compliant with RoHS directives without exemptions and REACH regulations

Applications

• Signal processing circuits
• Electronic switching applications
• Medium power amplification stages

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm qualification status. Standard versions are commercial grade, while suffixes such as -Q indicate AEC-Q101 compliance and -AQ indicates ongoing qualification. Ensure the selected part matches the required reliability level for the intended application environment before procurement.

Selection Notes

Select this component for designs requiring dual complementary transistors in a minimal footprint. Verify that the 45 V collector-emitter voltage rating meets circuit requirements. Confirm thermal management capabilities based on the target power dissipation limit of 250 mW under standard mounting conditions. Check if automotive-grade AEC-Q101 compliance is necessary for the project specifications.

Part Context

This component belongs to the BC846PN/BC847PN series of SMD general-purpose transistors. It serves as a compact solution for integrating both NPN and PNP functions into a single board location. The series is designed for commercial and industrial environments, providing a standardized interface for low-power analog and digital switching tasks.
