Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix to ensure correct packaging and automotive qualification status. Confirm RoHS compliance and lead times directly with authorized distributors or the manufacturer. Check for obsolescence notices as this component may be part of a legacy series with limited new design recommendations.

Single Bipolar Transistors Selection Notes

Select this component for designs requiring a robust PNP transistor with high current handling in a compact SOT-89 package. Ensure the application voltage does not exceed the 30 V limit. Consider the thermal management requirements given the 0.5 W power dissipation rating in surface-mount configurations.

Single Bipolar Transistors Part Context

This part belongs to the 2SAR552 family of middle power transistors. It serves as a complementary counterpart to NPN types like the 2SCR552.
