Procurement Notes
Verify the specific ordering suffix matches the required tape and reel configuration. Confirm that the selected current gain bin aligns with circuit design requirements. Ensure compliance with RoHS directives and REACH regulations before integration. Check the most recent datasheet revision for any updates to limiting values or thermal characteristics prior to finalizing the bill of materials.
Selection Notes
Select this component when a PNP transistor with high current handling and robust thermal performance is required. The exposed collector pad facilitates efficient heat dissipation on FR4 printed-circuit boards. Consider the specific hFE selection code to ensure proper biasing conditions are met. Verify that the operating temperature range fits within the specified junction and ambient limits.
