MBR1545CT-1HE3/45

Diode Arrays Overview

The MBR1545CT-1HE3/45 is a dual common-cathode Schottky barrier rectifier manufactured by Vishay General Semiconductor. It features a 45 V repetitive peak reverse voltage and a 7.5 A average forward current per diode in a TO-220AB package. The device utilizes silicon technology with a guard ring for overvoltage protection, ensuring low forward voltage drop and high efficiency. It operates within a junction temperature range of -65°C to 150°C.

Diode Arrays Feature Summary

• Dual common-cathode configuration for efficient rectification
• Guard ring structure provides enhanced overvoltage protection
• Low forward voltage drop reduces power losses
• High frequency operation capability

Diode Arrays Applications

• High frequency rectification in switching mode power supplies
• Freewheeling diodes in DC-to-DC converters
• Polarity protection circuits

Diode Arrays Procurement Notes

Verify the specific suffix "-1HE3" against official Vishay documentation, as standard listings often use "-E3" or "-HE3". Confirm RoHS compliance status and check for End-of-Life notifications, as this component family may have been discontinued. Ensure the TO-220AB package matches your PCB footprint requirements before ordering.

Diode Arrays Selection Notes

Select this component for applications requiring low forward voltage and high surge capability in a through-hole package. Compare the 7.5 A rating and 45 V breakdown against circuit demands. Consider thermal management needs due to the TO-220AB package size and verify compatibility with high-frequency switching environments.

Diode Arrays Part Context

This part belongs to the MBR15xxCT series of dual common-cathode Schottky rectifiers from Vishay. These devices are designed for general-purpose rectification in low-voltage, high-frequency inverters. The series typically includes variants with different voltage ratings while maintaining similar current handling and packaging characteristics.

Diode Arrays Replacement Considerations

Vishay lists MBRB1545CT-E3/45 as a similar alternative. Other manufacturers such as STMicroelectronics offer comparable parts like the STPS2045CT. Verify pinout compatibility and electrical parameters when substituting.
