BC817DPN-QX

Overview

The BC817DPN-QX is a dual NPN/PNP general-purpose transistor array manufactured by Nexperia USA Inc. It integrates one NPN and one PNP bipolar junction transistor within a single SC-74 (SOT-457) surface-mount package. The device supports a maximum continuous collector current of 500 mA and withstands a collector-emitter voltage of 45 V. Key electrical parameters include a minimum DC current gain (hFE) of 160 at 100 mA, saturation voltages up to 700 mV, and transition frequencies of 100 MHz for the NPN and 80 MHz for the PNP element. Total power dissipation reaches 600 mW, with an operating temperature range extending to 150°C.

Feature Summary

• Dual configuration combining complementary NPN and PNP transistors in a compact footprint
• High current handling capability suitable for switching and amplification tasks
• Qualified for automotive applications under AEC-Q101 standards

Applications

• General-purpose switching circuits requiring complementary logic or push-pull stages
• Automotive electronics systems demanding qualified components
• Audio frequency amplification and signal processing applications

Procurement Notes

Verify the specific suffix against official Nexperia documentation to confirm exact binning and packaging specifications. Ensure compatibility with design requirements regarding thermal management and pinout orientation. Confirm RoHS compliance status through the manufacturer's latest datasheet before finalizing procurement orders.

Selection Notes

Select this component when space constraints necessitate a dual-transistor solution in the SC-74 package. Compare hFE bins and saturation voltage limits against circuit requirements. Consider the complementary nature of the internal NPN and PNP structures for efficient driver stage implementation.

Part Context

This part belongs to the BC817 series of general-purpose NPN transistors produced by Nexperia. The DPN variant specifically denotes a dual array containing both NPN and PNP elements. This configuration simplifies board layout compared to using discrete individual transistors for complementary functions.

Replacement Considerations

Direct substitutes include other manufacturers' dual arrays in SOT-457 packages such as the 2SC3902/2SA1015 pairs if pinouts match. Verify electrical equivalence for current gain and voltage ratings before substitution.
