UG12JTHE3/45

Single Diodes Overview

The UG12JTHE3/45 is a general-purpose single rectifier diode manufactured by Vishay General Semiconductor - Diodes Division. It features a maximum repetitive peak reverse voltage of 600 V and an average forward rectified current rating of 12 A. The device utilizes a TO-220AC through-hole package and operates within a junction temperature range of -55°C to +150°C. Key electrical characteristics include a maximum forward voltage of 1.75 V at the rated current, a reverse leakage current of 30 µA, and a fast recovery time of 50 ns.

Single Diodes Feature Summary

• Fast recovery performance with a 50 ns switching time for efficient power conversion
• High thermal stability supporting operation up to 150°C junction temperature
• Robust 600 V reverse voltage blocking capability for high-voltage applications

Single Diodes Applications

• General purpose rectification in power supply circuits
• Freewheeling diodes in inductive load switching
• DC-DC converter output rectification

Single Diodes Procurement Notes

Verify component authenticity against official Vishay datasheets due to potential counterfeits. Confirm package integrity and marking legibility upon receipt. Ensure storage conditions comply with moisture sensitivity level requirements before soldering. Cross-reference pinout configurations with standard TO-220AC layouts to prevent installation errors during assembly processes.

Single Diodes Selection Notes

Select this component when a 600 V rating and 12 A continuous current capacity are required in a through-hole format. The 50 ns recovery time makes it suitable for higher frequency applications compared to standard rectifiers. Evaluate thermal management needs as the TO-220AC package requires adequate heatsinking for sustained high-current operation to maintain junction temperatures within safe limits.

Single Diodes Part Context

This part belongs to the UGx12xT series from Vishay, designed for general-purpose rectification tasks. It represents a standard solution for medium-power electronic designs requiring reliable high-voltage blocking and moderate current handling capabilities in a robust mechanical package suitable for manual or automated through-hole assembly workflows.

Single Diodes Replacement Considerations

Direct substitutes may include other Vishay 600V 12A TO-220AC rectifiers such as the UG12JT-E3/45. Verify that replacement parts match the exact pinout, thermal resistance, and electrical specifications to ensure circuit compatibility without redesign.
