Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix, such as -AP, to confirm packaging and tape-and-reel specifications if applicable. Confirm RoHS compliance status and lead-free material declarations against the latest manufacturer documentation. Ensure the package variant matches the required PCB footprint, specifically TO-226-3 or TO-92-3. Check product status indicators, as some listings may indicate obsolete status requiring alternative sourcing strategies.

Single Bipolar Transistors Selection Notes

Select this component when a 3A NPN transistor with 30V breakdown is required in a through-hole package. The 100MHz transition frequency supports moderate speed switching applications. Consider the 900mW power dissipation limit for thermal design constraints. Verify that the Base Island layout meets specific isolation or thermal requirements compared to standard planar structures.
