MBRB41H100CT-1G

Diode Arrays Overview

The MBRB41H100CT-1G is a silicon Schottky rectifier diode array manufactured by Fairchild Semiconductor, now part of onsemi. It features a dual anode common cathode configuration housed in an I2PAK surface-mount package. The device supports a repetitive reverse voltage of 100 V and provides a total average forward current of 40 A. Key electrical parameters include a maximum forward voltage of 900 mV and a surge forward current rating of 350 A. It operates within a junction temperature range up to 175°C.

Diode Arrays Feature Summary

• Dual anode common cathode configuration for efficient power management
• Low forward voltage characteristic to minimize conduction losses
• High thermal stability with 175°C operating junction temperature
• Robust surge capacity for handling transient current loads

Diode Arrays Applications

• Switch-mode power supply output rectification
• Free-wheeling diode applications in inductive circuits
• DC-DC converter bridge rectification
• General purpose power rectification in high-efficiency systems

Diode Arrays Procurement Notes

Verify the manufacturer designation carefully, as this component is associated with both Fairchild Semiconductor and onsemi due to corporate acquisition history. Confirm the specific suffix -1G indicates RoHS compliance and lead-free status. Ensure the I2PAK package variant matches the required PCB footprint. Check current availability status as distribution channels may list obsolete or active stock differently.

Diode Arrays Selection Notes

Select this component when a dual-anode Schottky configuration is required for synchronous rectification or free-wheeling duties. The 100 V rating suits low-voltage DC bus applications. The 40 A total current capability requires adequate thermal management via the exposed pad. Compare against single-diode alternatives if space constraints allow, noting the shared cathode simplifies circuit layout compared to discrete pairs.

Diode Arrays Part Context

This device belongs to the MBRB series of high-current Schottky rectifiers designed for surface-mount assembly. The I2PAK package offers superior thermal dissipation compared to standard TO-263 variants. It serves as a replacement for older through-hole equivalents in modern compact power supplies. The H-series designation typically denotes optimized barrier technology for lower forward voltage drop at elevated temperatures.

Diode Arrays Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Cross-reference with MBRB41H100CT from other manufacturers only after verifying identical pinout, voltage, and current ratings.
