CLA110MB1200NA

SCRs - Modules Overview

The IXYS CLA110MB1200NA is a high-efficiency thyristor module designed for AC power control applications. It features a dual back-to-back SCR configuration housed in a SOT-227B (miniBLOC) surface-mount package. The device supports a repetitive peak reverse voltage of 1200 V and an RMS on-state current of 50 A. Key electrical parameters include a maximum gate trigger current of 80 mA, a maximum gate trigger voltage of 1.6 V, and a surge current rating of 1.19 kA. The module operates at a maximum junction temperature of 125°C and weighs approximately 30 grams.

SCRs - Modules Feature Summary

• Dual back-to-back thyristor structure enables full-wave AC power control within a single compact module.
• Surface-mount SOT-227B packaging facilitates automated assembly and efficient PCB layout.
• High-efficiency silicon construction optimized for line-frequency industrial applications.

SCRs - Modules Applications

• Industrial heating regulation
• Lighting dimmer circuits

SCRs - Modules Procurement Notes

Verify the specific datasheet revision and RoHS compliance status prior to integration, as environmental declarations may vary by production batch. Confirm that the SOT-227B footprint matches the target PCB design, ensuring adequate thermal clearance for the 125°C operating limit. Cross-reference the manufacturer's latest product change notifications to ensure component continuity and performance consistency during long-term procurement cycles.

SCRs - Modules Selection Notes

Select this component when a surface-mount solution is required for full-wave AC control with moderate current handling capabilities. The 50 A RMS rating suits applications where space constraints preclude larger chassis-mounted modules. Ensure the driving circuit can supply the specified 80 mA gate trigger current reliably. Consider thermal management requirements carefully, as the surface-mount package relies on PCB copper area for heat dissipation under continuous load conditions.

SCRs - Modules Part Context

This part belongs to the IXYS CLA series of high-efficiency thyristor modules. It shares the SOT-227B form factor with other variants like the CLA100PD1200NA but differs in internal configuration and current ratings. The series targets industrial markets requiring robust, compact AC switching solutions. Unlike single-phase controllers, this dual-thyristor design simplifies circuit topology for bidirectional power flow applications.

SCRs - Modules Replacement Considerations

Direct pin-compatible replacements are limited due to the specific dual-thyristor architecture. Verify if alternative IXYS models such as the CLA100PD1200NA meet the current and voltage requirements, noting differences in internal configuration. Manual substitution requires re-evaluation of thermal performance and gate drive compatibility.
