Diode Arrays Procurement Notes
Verify the specific suffix HM3 confirms halogen-free compliance and AEC-Q101 qualification status. Confirm the I suffix indicates tape and reel delivery mode with a base quantity of 800 units. Ensure the component matches the D2PAK (TO-263AB) mechanical outline dimensions for proper PCB footprint compatibility during procurement.
Diode Arrays Selection Notes
Select this component when a dual common cathode configuration is required for space-constrained surface mount designs. The D2PAK package offers lower thermal resistance compared to leaded alternatives. Consider the 45 V rating and 15 A total current capacity against circuit requirements. Verify that the AEC-Q101 qualification meets specific automotive industry standards if applicable.
Diode Arrays Part Context
This part belongs to the Vishay MBRB15xxCT series of dual common cathode Schottky rectifiers. The series includes variants with different voltage ratings such as 60 V. The MBRB prefix denotes the surface mount D2PAK package style, distinguishing it from the MBRF through-hole ITO-220AB variant within the same electrical family.
