Single Bipolar Transistors Procurement Notes

Verify component authenticity due to market prevalence of代工贴牌 units. Confirm RoHS compliance status via official datasheet. Check lifecycle status as the product may be approaching obsolescence. Ensure package integrity matches TO-220-3 specifications. Validate supplier authorization for onsemi products.

Single Bipolar Transistors Selection Notes

Select this PNP BJT for applications requiring moderate voltage isolation up to 150 V and current handling near 1.5 A. Consider thermal management requirements given the 25 W power dissipation rating. Evaluate hFE range suitability for specific gain requirements. Compare against NPN alternatives if circuit topology demands complementary pairing.
