Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm pinout configuration and packaging type. Ensure the component meets required radiation hardness or environmental specifications if used in harsh conditions. Cross-reference datasheet revisions to validate absolute maximum ratings before finalizing procurement orders.

Selection Notes

Select this component for designs requiring high-voltage PNP switching or amplification within a standard through-hole footprint. Evaluate the DC current gain requirements against the specified minimum values for your operating point. Consider thermal management strategies given the 625 mW dissipation limit in enclosed environments.
