MUR1640CTH

Overview

The MUR1640CTH is a common cathode ultra-fast recovery rectifier diode array manufactured by onsemi. It features two elements with a maximum repetitive peak reverse voltage of 400 V and an average rectified output current of 8 A per diode. The device utilizes TO-220AB (ITO-220AB) packaging with isolated mounting tabs for thermal efficiency. Key electrical characteristics include a maximum forward voltage of 1.3 V at 8 A and a reverse leakage current of 10 µA at 400 V. It operates within a junction temperature range of -55 °C to 150 °C and carries AEC-Q101 automotive qualification.

Feature Summary

Ultra-fast recovery technology ensures high efficiency in switching applications
Common cathode configuration simplifies circuit design for dual-diode requirements
Automotive grade reliability certified under AEC-Q101 standards
Isolated mounting tab facilitates secure heat sink attachment

Applications

Switching power supplies
Converters
Freewheeling diodes
Reverse battery protection circuits

Procurement Notes

Verify the manufacturer designation carefully, as the MURF1640 series is primarily associated with Taiwan Semiconductor. Confirm that the specific suffix CTH corresponds to the correct package variant and that the component meets required automotive quality standards before integration into final designs.

Selection Notes

Select this component when high-speed recovery and automotive reliability are required. Ensure the 400 V reverse voltage rating exceeds the circuit's peak inverse voltage. Verify that the 8 A current handling capability aligns with the load requirements and that the TO-220AB package fits the available thermal management space.

Part Context

This part belongs to the MURF series of ultra-fast recovery rectifiers designed for high-frequency operation. The series offers improved performance over standard recovery diodes, making it suitable for modern power conversion topologies where efficiency and speed are critical parameters.
