Diode Arrays Procurement Notes

Verify that the specific ordering suffix HM3 corresponds to the required AEC-Q101 automotive qualification level rather than standard commercial grade. Confirm the delivery mode matches the 'I' suffix designation for tape and reel packaging. Ensure the procurement documentation references Document Number 88677 to validate the revision date and technical specifications against the manufacturer's official datasheet.

Diode Arrays Selection Notes

Select this component when automotive-grade reliability is mandated alongside high-frequency rectification requirements. The D2PAK package offers thermal performance advantages over through-hole alternatives while maintaining a compact footprint. Consider the 45 V rating and 30 A total current capacity to ensure adequate headroom for the target application's peak load and reverse voltage stress conditions.

Diode Arrays Part Context

This part belongs to the MBRB3045CT family of dual common cathode Schottky rectifiers from Vishay. The HM3 variant specifically denotes compliance with AEC-Q101 standards, distinguishing it from the standard M3 commercial grade version. It shares the same electrical ratings and mechanical dimensions as other variants in the series but targets applications requiring stricter automotive quality control and validation protocols.

Diode Arrays FAQ

What does the HM3 suffix indicate for this component?

The HM3 suffix indicates that the component is RoHS-compliant, halogen-free, and qualified according to the AEC-Q101 automotive standard.

Is the heatsink terminal electrically connected to the cathode?

Yes, the datasheet specifies that the case connection is the cathode, meaning the exposed pad/heatsink terminal is electrically common with the cathode pins.

What is the maximum non-repetitive peak forward surge current?

The maximum non-repetitive peak forward surge current is 200 A per diode, measured under an 8.3 ms single half sine-wave condition superimposed on rated load.
