MS0690J-DL1TE

Overview

The MS0690J-DL1TE is a thyristor AC controller module designed for mains frequency operation at 50 Hz or 60 Hz. It integrates two SCR dies in an anti-parallel configuration within a robust SOT-227B package. The device supports a repetitive peak off-state voltage of 600 V and an RMS on-state current of 90 A at a case temperature of 92 °C. It handles non-repetitive surge currents up to 950 A with a critical di/dt rating of 200 A/µs. The module features glass-passivated junctions, a minimum isolation voltage of 2500 V, and operates within a virtual junction temperature range of -40 °C to 125 °C.

Feature Summary

• High current handling capability with integrated dual SCR dies in anti-parallel configuration
• Robust SOT-227B package providing high isolation voltage and thermal stability
• Glass-passivated junctions for enhanced reliability under harsh conditions

Applications

• High power electrical tankless water heaters
• Mains frequency power control systems
• Resistive or inductive heating applications

Procurement Notes

Verify the specific ordering suffix against Littelfuse documentation to confirm packaging quantity and manufacturing location codes. Ensure the component meets RoHS compliance requirements for your assembly process. Cross-reference the datasheet revision date with your design specifications to account for any potential parameter updates. Confirm that the SOT-227B mounting dimensions align with your mechanical constraints before finalizing procurement.

Selection Notes

Select this module when designing circuits requiring efficient AC power control for resistive loads at standard mains frequencies. The dual SCR anti-parallel structure eliminates the need for external back-to-back configurations. Consider the thermal resistance and maximum allowable case temperature curves to ensure adequate heat sinking for the required RMS current levels. Verify gate trigger parameters match your driver circuit capabilities.

Part Context

This component belongs to the Littelfuse thyristor module family, specifically engineered for industrial and commercial power control. It utilizes silicon technology housed in epoxy encapsulation rated UL 94V-0. The SOT-227B form factor allows for screw-mount installation, facilitating integration into larger power assemblies where high current density and reliable switching are critical for system performance.

Replacement Considerations

Consult Littelfuse official substitution guides for verified equivalent part numbers. Ensure any replacement maintains identical pinout configurations, voltage ratings, and thermal characteristics to preserve system integrity without redesigning the host circuitry.
