MB20H100CTHM3/I

Diode Arrays Overview

The Vishay MB20H100CTHM3/I is a dual common cathode high voltage Schottky rectifier utilizing High Barrier Technology for improved high-temperature performance. It operates with a maximum repetitive peak reverse voltage of 100 V and provides a total maximum average forward rectified current of 20 A (10 A per diode). The device features a low forward voltage drop, reaching 0.64 V at 20 A and 125 °C, alongside a low leakage current of 4.5 μA at 25 °C. It supports a peak forward surge current of 250 A and functions within an operating junction temperature range of -65 °C to +175 °C.

Diode Arrays Feature Summary

• High Barrier Technology designed for enhanced high-temperature operation
• Guardring structure implemented for overvoltage protection
• Low forward voltage drop contributing to reduced power loss and high efficiency
• Qualified to AEC-Q101 automotive standards

Diode Arrays Applications

• Freewheeling diodes in DC/DC converters
• Polarity protection circuits

Diode Arrays Procurement Notes

Verify the specific suffix HM3/I against official documentation to confirm RoHS compliance, halogen-free status, and AEC-Q101 qualification. Ensure the D2PAK (TO-263AB) package matches the required thermal resistance and mounting torque specifications for the target application environment.

Diode Arrays Selection Notes

Select this component when a dual common cathode configuration is required for space-constrained designs. The D2PAK package offers lower thermal resistance compared to through-hole alternatives. Verify that the 100 V rating aligns with the circuit's peak reverse voltage requirements and that the 20 A total current capacity meets the load demands.

Diode Arrays Part Context

This part belongs to the MB20HxxCT series from Vishay General Semiconductor. It shares the same electrical characteristics as the MF20H100CT but utilizes a surface mount D2PAK (TO-263AB) package instead of the ITO-220AB through-hole case. Both variants are available in the same datasheet under Document Number 87736.
