Diode Arrays Procurement Notes

Verify the specific ordering suffix /4W to confirm the tube packaging format and base quantity of 50 units per tube. Ensure the E3 suffix is present to guarantee compliance with RoHS directives and JESD 201 class 1A whisker test requirements. Cross-reference the document number 88677 for the most current technical specifications and mechanical data before finalizing procurement.

Diode Arrays Selection Notes

Select this component when a dual common-cathode configuration is required for space-constrained designs using through-hole mounting. The TO-220AB package offers a thermal resistance of 1.5 °C/W per diode, suitable for applications requiring efficient heat dissipation without active cooling. Consider the 45 V rating for low-voltage systems where standard silicon rectifiers would incur higher conduction losses.

Diode Arrays Part Context

This part belongs to the MBR30 series of dual common-cathode Schottky rectifiers from Vishay. The series includes variations such as the 35 V rated MBR3035CT and surface-mount versions like the MBRB3045CT in D2PAK packages. All variants share similar electrical performance profiles optimized for low power loss and high-frequency operation in modern electronic power conversion systems.

Diode Arrays Replacement Considerations

Direct pin-compatible alternatives within the same family include the MBR3035CT-E3/4W for 35 V applications. Surface-mount equivalents are available as the MBRB3045CT-E3/45 in the D2PAK (TO-263AB) package. Verify that any substitute maintains the required 45 V reverse voltage and 30 A total current ratings.
