BC817DS,115

Overview

The Nexperia BC817DS,115 is a dual NPN general-purpose transistor housed in the SOT-457 (SC-74) surface-mount package. It features two independent NPN transistors with a maximum collector current of 500 mA and a collector-emitter voltage rating of 45 V. The device supports a collector-base voltage of 50 V and an emitter-base voltage of 5 V. Operating within a temperature range of -65°C to +150°C, it offers a minimum DC current gain (hFE) of 200 and a transition frequency up to 175 MHz. Total power dissipation is rated at 380 mW.

Feature Summary

• Dual NPN configuration for compact circuit design
• High current capability suitable for switching applications
• AEC-Q101 qualified for automotive reliability

Applications

• General-purpose switching circuits
• Amplifier stages
• Automotive electronics systems

Procurement Notes

Verify the specific suffix against official Nexperia documentation to confirm pinout and electrical tolerances. Ensure the ordering code matches the required AEC-Q101 qualification status. Confirm package dimensions align with PCB footprint requirements before finalizing procurement orders.

Selection Notes

Select this component when a dual NPN solution is required in a small form factor. Compare hFE ranges and thermal resistance against single-transistor alternatives if space permits. Verify that the 45 V rating meets the circuit's maximum voltage stress conditions under all operating scenarios.

Part Context

This part belongs to the BC817 series of NPN general-purpose transistors manufactured by Nexperia. The series includes variants with different packages and gain groupings. The BC817DS variant specifically provides a dual NPN structure in the SOT-457 package, complementing the single-transistor BC817 models.

Replacement Considerations

Check for direct equivalents such as the BC817DS from other manufacturers or alternative dual NPNs in SOT-457 packages. Verify pin compatibility and electrical parameter overlaps before substitution.
