Procurement Notes

Verify that the ordering suffix matches the required current gain bin, as the -25 designation indicates specific hFE characteristics. Confirm the package type is SOT223 and ensure the supply source provides documentation confirming AEC-Q101 qualification status. Check for any specific marking codes corresponding to the production batch to ensure traceability.

Selection Notes

Select this component when designing circuits requiring robust NPN switching or amplification with high current handling. The -25 variant is appropriate where a guaranteed minimum current gain of 160 is necessary. Consider the thermal resistance values provided for different PCB footprint sizes to ensure adequate heat dissipation. Ensure the operating voltage remains below the 20 V collector-emitter limit.
