MBRB20H100CT-M3/I

Diode Arrays Overview

The MBRB20H100CT-M3/I is a dual common cathode high voltage Schottky rectifier manufactured by Vishay General Semiconductor. It utilizes High Barrier Technology to improve high-temperature performance and features a D2PAK (TO-263AB) surface-mount package. The device provides a maximum repetitive peak reverse voltage of 100 V and a total maximum average forward rectified current of 20 A, with each diode rated for 10 A. Key electrical characteristics include a low forward voltage drop of 0.88 V at 20 A and 25 °C, a maximum reverse leakage current of 4.5 μA at 25 °C, and a peak forward surge current capability of 250 A. The operating junction temperature range extends from -65 °C to +175 °C.

Diode Arrays Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm the exact package type and delivery mode. The M3 designation indicates halogen-free RoHS compliance, while the I suffix specifies tape and reel packaging. Confirm that the component meets the required environmental standards for your specific application before procurement.

Diode Arrays Selection Notes

Select this component when a surface-mount dual Schottky rectifier with high thermal stability is required. The D2PAK package facilitates efficient heat dissipation through the exposed pad. Ensure the circuit design accommodates the 100 V reverse voltage rating and the 20 A total current capacity under expected operating temperatures.

Diode Arrays Part Context

This part belongs to the MBR20H100CT family of dual common-cathode high-voltage Schottky rectifiers. The family includes variants in TO-220AB and ITO-220AB packages, such as the MBR20H100CT and MBRF20H100CT. All variants share identical electrical ratings but differ in mechanical housing and thermal resistance specifications.

Diode Arrays Replacement Considerations

Direct substitutes within the same Vishay family include MBR20H100CT-E3/45 (TO-220AB tube) and MBRF20H100CT-E3/45 (ITO-220AB tube). Verify pinout compatibility and thermal management requirements when substituting between package types.
