BC817DPN/DG/B3X

Overview

The BC817DPN/DG/B3X is a dual bipolar junction transistor array manufactured by Nexperia, featuring one NPN and one PNP transistor within a single package. It utilizes the SC-74 (SOT-457) surface-mount housing with six pins. The device supports a maximum collector-emitter voltage of 45V and a continuous collector current of 500mA per transistor. Total power dissipation reaches 600mW at an ambient temperature of 25°C. The component operates across a junction temperature range from -65°C to +150°C and meets RoHS standards.

Feature Summary

• Integrates complementary NPN and PNP transistors into a compact footprint to minimize board space.
• Provides matched electrical characteristics for differential signal processing applications.
• Supports high-frequency operation suitable for general-purpose switching and amplification tasks.

Applications

• Differential amplifier circuits requiring matched transistor pairs
• General-purpose switching logic interfaces
• Audio pre-amplifier stages

Procurement Notes

Verify the specific suffix B3X against official Nexperia documentation to confirm tape-and-reel packaging quantities and lot traceability requirements. Ensure compatibility with standard pick-and-place equipment regarding the SC-74 package dimensions before finalizing procurement orders.

Selection Notes

Select this component when a design requires both NPN and PNP switching capabilities in a limited area. Compare total power dissipation limits against thermal constraints. Verify that the 45V breakdown voltage aligns with the circuit's maximum operating levels to prevent device failure.

Part Context

This part belongs to the BC817 family of general-purpose small-signal transistors. It serves as the dual-array counterpart to single units like the BC817-25. The series is widely used in consumer electronics and industrial control systems where space efficiency and reliable switching performance are critical design parameters.

Replacement Considerations

Direct substitutes include other manufacturers' SC-74 dual NPN/PNP arrays with matching 45V/500mA ratings. Verify pinout compatibility and hFE binning specifications to ensure functional equivalence without circuit modification.
