SCRs - Modules datasheet and documents for TM400DZ-24

TM400DZ-24

SCRs - Modules Overview

The Powerex TM400DZ-24 is a dual Silicon Controlled Rectifier (SCR) module rated for 1200 Volts and 400 Amperes average on-state current. It features isolated mounting for common heatsink integration, with a peak forward blocking voltage of 1200V and an RMS on-state current capability of 620A. The device supports a critical rate-of-rise of on-state current (di/dt) of 200 A/ms and offers a junction-to-case thermal resistance of 0.1 °C/Watt per module.

SCRs - Modules Feature Summary

Dual SCR configuration within a single isolated package
Low thermal impedance design for efficient heat dissipation
Isolated mounting structure enabling secure attachment to common heatsinks

SCRs - Modules Applications

AC and DC motor control systems
Lighting control circuits
Electric furnace temperature regulation
Contactless switching applications

SCRs - Modules Procurement Notes

Verify the complete eight-digit part number against official Powerex documentation before procurement. Confirm that the specific ordering suffix matches the required electrical ratings and terminal configurations. Ensure compatibility with standard M6 and M8 mounting hardware specifications defined in the datasheet outline drawing.

SCRs - Modules Selection Notes

Select this component for high-power phase control applications requiring dual SCR isolation. Evaluate thermal management requirements based on the 0.1 °C/Watt junction-to-case resistance. Consider the 400A average current rating at 66°C case temperature when designing the cooling system for continuous operation.

SCRs - Modules Part Context

This module belongs to the POW-R-BLOK™ series designed for robust industrial power electronics. It integrates two SCRs into one unit to simplify circuit layout and improve reliability in high-current environments compared to discrete components.
