Procurement Notes

Verify the specific suffix 'V3' against the manufacturer's official datasheet to confirm pinout compatibility and exact electrical tolerances. Ensure the ordering part number matches the required tape and reel configuration for your manufacturing process. Cross-reference the RoHS compliance status with the latest material declaration documents provided by onsemi before finalizing procurement.

Selection Notes

Select this component when a PNP digital transistor with a 4.7 kOhm base resistor is required. The 50 V breakdown voltage and 100 mA current rating suit low-to-medium power switching tasks. The SOT-723 package is appropriate for high-density PCB layouts. Verify that the thermal dissipation requirements are met within the specified operating temperature range.
