MBRB2045CT-M3/I

Diode Arrays Overview

The MBRB2045CT-M3/I is a dual common cathode Schottky rectifier manufactured by Vishay General Semiconductor. It utilizes the D2PAK (TO-263AB) surface-mount package and features a silicon carbide metal-silicon (SiC-Schottky) barrier construction for low forward voltage drop and high efficiency. The device provides a maximum repetitive peak reverse voltage of 45 V and supports a total average forward rectified current of 20 A, with each diode handling 10 A at a case temperature of 135 °C. It offers a peak forward surge current capability of 150 A per diode and operates within a junction temperature range of -65 to +150 °C.

Diode Arrays Procurement Notes

Verify that the specific ordering code matches the required package type and suffix specifications. Confirm compliance requirements such as RoHS and halogen-free status against project standards. Ensure thermal management design accounts for the specified junction-to-case thermal resistance values during operation.

Diode Arrays Selection Notes

Select this component when a surface-mount dual Schottky configuration is required for low voltage applications. Consider the D2PAK package for efficient heat dissipation compared to through-hole alternatives. Evaluate the 45 V rating against circuit peak reverse voltages to ensure adequate safety margins under all operating conditions.

Diode Arrays Part Context

This part belongs to the MBRB20xxCT series of dual common cathode Schottky rectifiers from Vishay. The 'M3' suffix indicates a lead-free, halogen-free finish compliant with environmental directives. The '/I' suffix specifies the tape and reel delivery format for automated assembly processes.

Diode Arrays Replacement Considerations

Cross-reference with other Vishay parts in the MBRB20xxCT family for different voltage ratings or package options. Verify pinout compatibility and thermal performance before substituting with components from other manufacturers.
