T620143004DN

Overview

The Powerex Inc. T620143004DN is a single Silicon Controlled Rectifier (SCR) module designed for phase control applications. It features a TO-200AB package with chassis mounting and 8-inch wire leads. The device supports a repetitive peak reverse voltage of 1400V and an on-state RMS current of 470A. Gate trigger current is specified at 150mA. Operating junction temperature ranges from -40°C to +125°C. Surge current capabilities include 5000A at 50Hz and 5500A at 60Hz.

Feature Summary

• Single SCR configuration optimized for high-power phase control circuits
• Robust TO-200AB construction ensuring reliable thermal management
• Integrated wire leads facilitate direct connection to external circuitry

Applications

• Industrial motor drives requiring precise speed regulation
• High-power AC power controllers and rectifiers
• Resistive and inductive load switching systems

Procurement Notes

Verify the specific datasheet version prior to ordering, as historical records may indicate variations in surge ratings or gate specifications. Confirm that the TO-200AB footprint and 8-inch lead length match the target assembly requirements. Ensure thermal interface materials are compatible with the chassis mount design for optimal heat dissipation during operation.

Selection Notes

Select this component when a single-phase SCR with high current capacity is required. The 1400V rating suits medium-voltage industrial applications. Consider the 470A RMS current limit against peak load demands. The TO-200AB package offers standard mounting dimensions, simplifying integration into existing power electronics architectures without custom mechanical modifications.

Part Context

This module belongs to Powerex's discrete thyristor lineup, utilizing silicon-controlled rectifier technology. It serves as a fundamental building block for converting AC to DC or controlling AC power flow. The TO-200AB form factor is widely recognized in heavy-duty industrial equipment for its balance of electrical performance and mechanical durability.

Replacement Considerations

The PM200RSA060 is an IGBT Intelligent Power Module and is not a functional substitute due to differing semiconductor technology and internal architecture. Direct replacements require matching SCR parameters such as voltage, current, and package type. Verify compatibility with equivalent models from other manufacturers before implementation.
