BC817DPN/DG/B2,115

Overview

The BC817DPN/DG/B2,115 is a dual bipolar junction transistor array manufactured by Nexperia USA Inc. It integrates one NPN and one PNP transistor within a compact SC-74 (SOT-457) surface-mount package. The device supports a maximum continuous collector current of 500 mA and features a collector-emitter breakdown voltage of 45 V. With a total power dissipation rating of 600 mW and a transition frequency up to 100 MHz, it is designed for general-purpose switching and amplification tasks in space-constrained electronic circuits.

Feature Summary

• Integrates complementary NPN and PNP transistors into a single component to reduce circuit board area and assembly complexity.
• Utilizes the ultra-small SC-74 plastic surface-mount package to facilitate high-density PCB layouts.
• Provides robust electrical performance with a 500 mA current handling capability suitable for general-purpose signal processing.

Applications

• General-purpose switching and logic interface circuits
• Audio frequency amplification stages
• Complementary push-pull output drivers

Procurement Notes

Verify the specific suffix against official Nexperia documentation to confirm pinout orientation and binning specifications. Ensure the ordering code matches the required tape-and-reel packaging format for automated assembly processes. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and traceability before finalizing procurement orders.

Selection Notes

Select this component when a matched NPN/PNP pair is required in a minimal footprint. Compare the 600 mW thermal limit against the application's duty cycle to ensure adequate heat dissipation. Verify that the 45 V voltage rating exceeds the maximum operating potential of the target circuit to prevent breakdown under transient conditions.

Part Context

This part belongs to the BC817 series of small-signal bipolar transistors produced by Nexperia. The series includes various single and dual configurations optimized for low-cost, high-volume consumer electronics. The BC817DPN variant specifically addresses designs requiring complementary symmetry in a leadless SC-74 package.

Replacement Considerations

Direct substitutes include BC817DPN,115 and BC817DPN,125 from Nexperia. Other manufacturers offer equivalent dual BJT arrays in SC-74 packages, but verification of hFE matching and pin compatibility is required.
