Procurement Notes

Verify the specific ordering suffix matches the required gain bin (-10) and packaging format. Confirm the package type corresponds to SOT89 with the correct pinout configuration. Ensure compliance with RoHS directives and REACH regulations for the intended market. Check the most recent datasheet revision for any updates to limiting values or thermal characteristics before finalizing the design.

Selection Notes

Select this component when a PNP transistor with high current handling and moderate voltage ratings is required. The -10 gain bin suits applications needing a predictable gain range between 63 and 160. Consider the SOT89 package for its balance of power dissipation and board space. Verify thermal resistance requirements against the PCB copper area available for heat sinking.

Part Context
