Single Diodes Procurement Notes

Verify the specific suffix LT1 to confirm tape-and-reel packaging configuration. Ensure compatibility with standard SOT-23 footprint dimensions during PCB layout. Confirm that the 100 V reverse voltage rating meets the peak transient requirements of the target application circuit. Validate thermal dissipation capabilities under maximum load conditions.

Single Diodes Selection Notes

Select this component when a small-form-factor switch diode is required for signals up to 100 V. The low capacitance makes it suitable for applications where signal distortion must be minimized. Consider the 200 mA current limit when designing power paths. The wide operating temperature range supports use in automotive or industrial sectors without additional cooling measures.

Single Diodes Part Context

This part belongs to onsemi's discrete semiconductor portfolio, specifically within the switch diode category. It complements other protection and switching components offered by the manufacturer.
