Procurement Notes

Verify the manufacturer origin carefully as this component was originally produced by Fairchild Semiconductor, which has undergone corporate restructuring. Ensure the specific suffix matches your supply chain requirements. Confirm RoHS compliance status directly with the supplier or authorized distributor before procurement to ensure adherence to environmental regulations.

Selection Notes

Select this component when a miniature glass axial package is required alongside low capacitance and rapid recovery times. It serves as a suitable alternative for standard small-signal switching tasks where high forward conductance is beneficial. Evaluate thermal derating factors if operating near the maximum junction temperature limits specified in the datasheet.
