Diode Arrays Procurement Notes

Verify the component revision status before procurement, as the datasheet explicitly marks this part as not recommended for new designs. Confirm that the bare lead frame packaging aligns with your assembly requirements. Ensure compliance with export control regulations if applicable. Validate that the specific application does not require higher reliability than general purpose ratings allow.

Diode Arrays Selection Notes

Select this component for applications requiring high current handling up to 60 A with moderate switching speeds. The TO3P-3L package necessitates board-level or chassis mounting solutions suitable for power modules. Consider the 1.0 °C/W thermal resistance when designing heatsinking strategies. Evaluate the 150 ns reverse recovery time against circuit switching frequencies to ensure acceptable performance levels.
