TN5050H-12PI

Scrs Overview

The TN5050H-12PI is a high-temperature Silicon Controlled Rectifier (SCR) manufactured by STMicroelectronics, designed for robust industrial power control applications. It features a TOP-3I through-hole package with three pins. The device supports a maximum repetitive peak off-state voltage of 1200 V and a surge voltage rating of 1400 V. It handles an RMS on-state current of 50 A with a maximum gate trigger current of 50 mA. The component operates at junction temperatures up to 150 °C, ensuring reliability in demanding thermal environments.

Scrs Feature Summary

• High temperature capability with junction temperature reaching 150 °C
• Robust blocking voltage rated at 1200 V for industrial stability
• Designed for lower gate current requirements to enhance immunity

Scrs Applications

• Motor soft starters
• Industrial power control systems requiring high immunity
• High temperature SCR thyristor circuits

Scrs Procurement Notes

Verify the specific suffix 'PI' against official STMicroelectronics documentation to confirm the exact pin configuration and mechanical dimensions associated with the TOP-3I package. Ensure that the 50 mA maximum gate trigger current aligns with the driver circuit design, as variations in suffixes may alter electrical characteristics or thermal performance specifications.

Scrs Selection Notes

Select this component when applications demand high thermal resilience and significant current handling capabilities. The 1200 V rating suits medium-voltage industrial systems, while the 50 A RMS capacity addresses substantial load requirements. Consider the TOP-3I package for through-hole mounting constraints and verify compatibility with existing thermal management solutions for 150 °C operation.

Scrs Part Context

This part belongs to the T5050H series of high-temperature SCRs from STMicroelectronics. It shares family traits such as high surge current tolerance and commutation capabilities. The TN5050H-12PI specifically denotes the 1200 V voltage class within this lineup, distinguishing it from lower voltage variants like the 800 V models found in related series.

Scrs Replacement Considerations

Cross-reference with other STMicroelectronics high-temperature SCRs in the T5050H series. Verify if alternative packages or voltage ratings meet the specific system requirements without compromising the 150 °C thermal limit or 50 A current capacity.
