MBRF2550CTH

Diode Arrays Overview

The MBRF2550CTH is a dual common-cathode Schottky barrier rectifier from the Taiwan Semiconductor MBRF25xCT series, housed in an ITO-220AB package. It features a repetitive peak reverse voltage (VRRM) of 50 V and a maximum average forward current (IF) of 25 A per diode. The device supports a surge peak forward current (IFSM) of 200 A and operates within a junction temperature range of -55 °C to +150 °C. The 'H' suffix indicates AEC-Q101 qualification.

Diode Arrays Feature Summary

• AEC-Q101 qualified for automotive reliability
• Guard ring structure provides overvoltage protection
• Low power loss with high efficiency operation
• High surge current capability

Diode Arrays Applications

• Switching mode power supplies (SMPS)
• Adapters
• DC to DC converters

Diode Arrays Procurement Notes

Verify that the ordering code includes the 'H' suffix to confirm AEC-Q101 qualification status. Ensure the required reverse voltage rating meets or exceeds the circuit's 50 V requirement. Confirm the ITO-220AB package type matches the board layout constraints. Check for RoHS compliance and halogen-free status according to IEC 61249-2-21 standards.

Diode Arrays Selection Notes

Select this component when a 50 V blocking voltage and 25 A continuous current are required in a surface-mount compatible through-hole package. The dual common-cathode configuration allows for use in full-wave rectification circuits. Consider the thermal resistance values for heat sink design if operating near maximum ratings.

Diode Arrays Part Context

This part belongs to the MBRF2535CT–MBRF25150CT series by Taiwan Semiconductor. The series offers various voltage ratings from 35 V to 150 V while maintaining a consistent 25 A current capacity and ITO-220AB mechanical footprint across all variants.

Diode Arrays Replacement Considerations

Cross-reference other manufacturers offering 25 A, 50 V Schottky rectifiers in the ITO-220AB package. Verify pinout compatibility and thermal characteristics before substitution.
