Diode Arrays Procurement Notes

Verify the specific suffix HE3 confirms AEC-Q101 qualification and compliance with JESD 201 class 2 whisker testing standards. Confirm the package designation matches the required TO-263AB footprint. Ensure the reverse voltage rating aligns with the circuit's maximum working peak reverse voltage requirements. Check for RoHS compliance documentation corresponding to the E3 suffix.

Diode Arrays Selection Notes

Select this component when a dual common cathode configuration is required for synchronous rectification or freewheeling paths. The TO-263AB package offers a balance of thermal dissipation and surface-mount convenience. Consider the 60 V rating against potential voltage spikes in the application. Evaluate the thermal resistance characteristics relative to the available heatsinking or PCB copper area.
