Single Bipolar Transistors Procurement Notes

Verify the specific suffix TL-E against official datasheets to confirm pinout and electrical tolerances. Confirm RoHS compliance status through manufacturer documentation before integration. Ensure thermal management aligns with the 900 mW dissipation limit. Validate that the 100 V rating meets circuit requirements. Check for end-of-life notices or discontinuance announcements from onsemi.

Single Bipolar Transistors Selection Notes

Select this component for designs requiring high current density in minimal space. The 3 A rating suits moderate power switching tasks. The 100 V breakdown voltage provides headroom for inductive loads. Consider the 380 MHz frequency for fast switching speeds. Evaluate thermal constraints due to the small footprint and 900 mW limit.
