Overview
The BC817BPN is a dual general-purpose NPN and PNP bipolar junction transistor manufactured by Diotec Semiconductor. It is housed in an SOT-26 surface-mount package containing two complementary transistors. The device supports a maximum collector current of 500 mA and a collector-emitter voltage (VCEO) of 45 V. Power dissipation is rated at 370 mW under standard conditions, extending to 600 mW with adequate PCB copper pad mounting. The DC current gain (hFE) ranges from 160 to 400. Transition frequencies are specified at 100 MHz for the NPN element and 80 MHz for the PNP element.
Feature Summary
- Integrates one NPN and one PNP transistor within a single compact SMD package
- Designed for universal commercial and industrial applications
- Compliant with RoHS directives without exemptions
Applications
- Push-Pull Amplifier circuits
- Signal processing stages
- Gate driver implementations
Procurement Notes
Verify component authenticity through official manufacturer channels or authorized distributors. Confirm compliance with specific project requirements regarding AEC-Q101 standards if automotive-grade reliability is necessary, as this requires specific suffix designations. Ensure proper handling procedures are followed during assembly to maintain device integrity.
Selection Notes
Select the BC817BPN when space-constrained designs require matched complementary NPN/PNP pairs. Evaluate thermal resistance parameters against the expected ambient temperature and PCB copper pad area to ensure power dissipation limits are not exceeded. Verify that the 45 V breakdown voltage meets the circuit's operational requirements.
Part Context
This component belongs to the BC817 series of small-signal transistors. It serves as the dual-transistor counterpart to single-element variants like the BC817-16. The SOT-26 package allows for efficient board space utilization compared to discrete component arrangements, making it suitable for dense electronic assemblies.
Replacement Considerations
Nexperia offers the BC817DPN as a functional equivalent in a 6-TSOP package. Both devices provide NPN/PNP configurations with similar electrical ratings.
