STPS50U100CR

Diode Arrays Overview

The STPS50U100CR is a dual power Schottky rectifier featuring an ultralow forward voltage drop, optimized for high-frequency switch mode power supplies. It provides a total average forward current of 50 A (25 A per diode) with a repetitive peak reverse voltage rating of 100 V. The device operates at a maximum junction temperature of 150 °C and exhibits a typical forward voltage of 0.64 V at 25 A and 125 °C. Packaged in the I2PAK format, it is designed to enhance efficiency in adapters and server SMPS applications.

Diode Arrays Procurement Notes

Verify the specific ordering code STPS50U100CR corresponds to the I2PAK package variant rather than the TO-220AB version. Confirm that the component meets required environmental compliance standards such as ECOPACK specifications before finalizing procurement decisions.

Diode Arrays Selection Notes

Select this component when designing high-efficiency power supplies requiring a dual Schottky rectifier configuration. Ensure the application supports through-hole mounting for the I2PAK package, as surface mount soldering of the metal slug is not permitted. Verify thermal management strategies align with the specified junction-to-case resistance values.

Diode Arrays Part Context

This part belongs to the ULVF™ series of power Schottky rectifiers from STMicroelectronics. It is specifically engineered to help manufacturers meet worldwide efficiency standards for power adapters. The dual-diode structure allows for efficient freewheeling or synchronous rectification in DC/DC converter topologies.

Diode Arrays Replacement Considerations

Check for compatible dual Schottky rectifiers with similar 100 V ratings and 50 A total current capacity. Ensure replacement parts support the same I2PAK footprint and thermal characteristics if direct pin-for-pin substitution is required.

Diode Arrays FAQ

Can the I2PAK metal slug be soldered like a surface mount device?

No, mounting the I2PAK metal slug with alloy like a surface mount device is not permitted. Standard through-hole mounting is mandatory.

What is the recommended snubber circuit for this device?

ST recommends using an RC clamping snubber circuit connected in parallel with the STPS50U100C device to ensure the peak reverse voltage remains below the absolute rating.
