Procurement Notes

Verify the specific suffix WHE3-TP against official Micro Commercial Components documentation to confirm the exact pinout and electrical tolerances for the SOT-323-3 variant. Ensure that procurement channels provide valid traceability records and authenticity guarantees. Confirm that the delivered units match the AEC-Q101 qualification status specified in the manufacturer's datasheet before integration into production lines.

Selection Notes

Select this component when an NPN transistor with 45V collector-emitter voltage and 500mA current capacity is required in a compact SOT-323-3 footprint. Consider this part for designs needing AEC-Q101 compliance and operation up to 150°C junction temperature. Evaluate the 200mW power dissipation limit and 100MHz transition frequency against the specific signal and thermal requirements of the target application circuit.

Part Context

This device belongs to the BC817 series of NPN general-purpose transistors produced by Micro Commercial Components. The series offers various voltage and packaging options to suit different design constraints. The BC817-25WHE3-TP specifically utilizes the SOT-323-3 package, distinguishing it from other series members that may use SOT-23 or larger packages while maintaining similar core electrical characteristics.

Replacement Considerations

Cross-reference with other manufacturers offering NPN transistors in SOT-323-3 packages with matching 45V VCEO and 500mA Ic ratings.
