Diode Arrays Procurement Notes

Verify the specific suffix HE3 indicates high reliability grade (AEC Q101 qualified) rather than standard consumer grade E3. Confirm the ITO-220AB package designation matches the required isolation voltage specifications if terminal-to-heatsink isolation is necessary. Check datasheet revision 88670 for updated thermal resistance values.

Diode Arrays Selection Notes

Select this component when low forward voltage drop and high efficiency are critical for power loss reduction. Ensure the application requires a dual common-cathode configuration suitable for synchronous rectification or bridgeless PFC topologies. Verify that the 35 V reverse voltage rating aligns with the circuit's peak inverse voltage requirements.
