MBRF2545CTH

Diode Arrays Overview

The MBRF2545CTH is a Schottky rectifier diode manufactured by Taiwan Semiconductor Corporation, housed in an TO-263AB (D2PAK) surface-mount package. It features a dual common cathode configuration with two silicon elements. Key electrical parameters include a maximum repetitive peak reverse voltage of 45 V and an average forward rectified current of 25 A per element. The device exhibits a maximum forward voltage of 820 mV at rated current and supports a non-repetitive peak forward surge current of 200 A. It operates within a junction temperature range of -65 °C to +175 °C and complies with RoHS standards.

• Free-wheeling rectification in inductive loads
• Power supply output stages
• Reverse polarity protection circuits

Diode Arrays Procurement Notes

Verify the specific suffix 'TH' against the manufacturer's official datasheet to confirm tape-and-reel packaging specifications and terminal plating details. Ensure the procurement source provides the original Taiwan Semiconductor document rather than third-party summaries to validate the exact thermal resistance and pinout orientation for the D2PAK variant.

Diode Arrays Selection Notes

Select this component when a surface-mount solution is required for high-current applications needing low forward voltage drop. Compare thermal performance metrics such as junction-to-case thermal resistance against through-hole alternatives like the TO-220 version if board space is constrained. Confirm that the 45 V rating aligns with the system's peak reverse voltage requirements under all operating conditions.

Diode Arrays Part Context

This part belongs to the MBR series of Schottky rectifiers from Taiwan Semiconductor, designed for general-purpose power conversion. The 'F' indicates the surface-mount D2PAK package, while 'CT' denotes the dual common cathode structure. This series is engineered to replace traditional p-n junction rectifiers where speed and efficiency are critical.

Diode Arrays Replacement Considerations

Cross-reference with MBR2545CTG for equivalent electrical performance in through-hole packages. Verify compatibility with MBR3045CT variants if higher current capacity is acceptable. Ensure substitute parts maintain the same 45 V reverse voltage rating and dual common cathode configuration.
