SR4050PT C0G

Diode Arrays Overview

The SR4050PT C0G is a dual common cathode Schottky barrier rectifier manufactured by Taiwan Semiconductor. It features two silicon elements in a TO-247AD (TO-3P) package with three terminals. The device has a maximum repetitive peak reverse voltage of 50V and an average forward current rating of 40A. Key electrical parameters include a maximum non-repetitive peak forward surge current of 400A, a typical junction-to-case thermal resistance of 1.2 °C/W, and a maximum operating junction temperature range of -55°C to +125°C or +150°C depending on specific variant conditions.

Diode Arrays Procurement Notes

Verify the exact voltage rating suffix matches the required circuit specification, as the series spans multiple voltage options. Confirm RoHS compliance and halogen-free status against IEC 61249-2-21 standards if required. Ensure the TO-247AD package mounting torque does not exceed 1.13 N⋅m during installation. Check for AEC-Q101 qualification availability if automotive grade reliability is necessary for the application.

Diode Arrays Selection Notes

Select this component based on the 50V reverse voltage requirement and 40A continuous current capacity. Consider the thermal management needs given the 1.2 °C/W junction-to-case resistance. Evaluate the forward voltage characteristics at the expected operating current to ensure efficiency targets are met. Verify that the dual common cathode configuration aligns with the circuit topology requirements.

Diode Arrays Part Context

This part belongs to the SR40xPT series of Schottky barrier rectifiers from Taiwan Semiconductor. The series offers various voltage ratings from 20V to 100V while maintaining a consistent 40A current rating. The devices utilize silicon technology and are housed in the TO-247AD package, designed for through-hole mounting applications requiring high current handling capabilities.

Diode Arrays Replacement Considerations

Direct substitutes within the same series include SR4020PT, SR4030PT, SR4040PT, SR4060PT, SR4090PT, and SR40100PT, differing primarily in their reverse voltage ratings. Cross-manufacturer replacements must match the 40A current, 50V voltage, TO-247AD package, and dual common cathode configuration.
