Single Diodes Procurement Notes

Verify the specific suffix 'C' against the official Microchip datasheet to confirm exact mechanical dimensions and marking codes. Ensure the procurement specification aligns with the DO-4 package style. Confirm RoHS compliance status as historical data may vary by production batch. Validate that the 600V rating meets the circuit's peak inverse voltage requirements before finalizing orders.

Single Diodes Selection Notes

Select this component when a high-current, high-voltage standard recovery diode is required for through-hole assembly. The 16A current rating supports substantial load demands, while the 600V blocking voltage provides adequate margin for industrial line voltages. Consider the 200°C junction temperature limit for environments with elevated ambient heat or poor ventilation compared to lower-rated alternatives.

Single Diodes Part Context
