Procurement Notes

Verify the specific part number suffix against official MCC documentation to confirm exact pinout and electrical tolerances. Ensure the selected variant matches the required package type and thermal characteristics for the target application environment. Cross-reference datasheet revisions to confirm compliance with current regulatory standards before finalizing procurement orders.

Selection Notes

Select this component when a dual-diode solution is required in a minimal footprint SOT-363 package. Consider the 80 V reverse voltage rating and 500 mA forward current limits to ensure adequate headroom for the intended circuit loads. Evaluate the 4 ns recovery time against the system's switching frequency requirements to minimize signal distortion and power loss during transitions.
