What should engineers review before using US2D(SMB)?

Review voltage transients against the 200 V repetitive reverse-voltage limit, account for the 1.0 V maximum forward voltage at 2 A, derate forward current with case temperature, and confirm the cathode pad orientation.

What is the pinout of US2D(SMB)?

Use the US2D(SMB) datasheet for the official pinout diagram and pin names. In PartGenie, ask Datasheet AI about US2D(SMB) pinout to locate pins, power rails, and interface signals before layout.
