Procurement Notes

Verify the exact suffix against official Panasonic Industry documentation to confirm resistance values and binning. Confirm lifecycle status as maintenance or discontinued before finalizing procurement plans. Ensure compatibility with RoHS Directive requirements for your specific manufacturing region.

Selection Notes

Select this component when a compact PNP transistor with integrated biasing is required for space-constrained digital designs. Verify that the 0.51 kΩ base and 5.1 kΩ emitter resistor values align with your circuit's drive requirements. Consider the 150 mW power dissipation limit when designing thermal management strategies.

Part Context
