Single Bipolar Transistors Procurement Notes

Verify the specific suffix 'T1' against official onsemi documentation to confirm exact binning or tape-and-reel specifications. Ensure compatibility with SC-75 footprint requirements during PCB layout. Confirm RoHS compliance status through the manufacturer's latest material declaration before final procurement approval.

Single Bipolar Transistors Selection Notes

Select this component when a small-form-factor PNP transistor is required for low-current switching tasks. Compare the 100 mA current limit and 50 V voltage rating against circuit demands. Consider the 30 MHz frequency response for high-speed logic applications where faster alternatives are unnecessary.
