Diode Arrays Procurement Notes

Verify the specific suffix HE3 confirms AEC-Q101 qualification status. Confirm the ITO-220AB package designation matches the required mounting configuration. Check RoHS compliance documentation as indicated by the E3 suffix. Ensure the 45 V rating aligns with the circuit's peak reverse voltage requirements. Validate that the thermal resistance values are suitable for the intended heat dissipation environment.

Diode Arrays Selection Notes

Select this component when high-frequency operation and low forward voltage drop are critical for efficiency. The ITO-220AB package offers isolation from the heatsink, which is necessary if the cathode cannot be grounded directly. Consider the 175 °C maximum junction temperature for high-ambient environments. Verify that the 150 A surge current capability meets the transient load requirements of the application.
