TYN1212RG

Scrs Overview

The TYN1212RG is a standard Silicon Controlled Rectifier (SCR) manufactured by STMicroelectronics, designed for high-power switching applications. It features an on-state RMS current rating of 12 A and a repetitive peak off-state voltage of 1200 V. The device is housed in a TO-220AB through-hole package, suitable for robust industrial environments. Key electrical characteristics include a gate trigger current of less than 15 mA and a holding current of 30 mA. It operates within a junction temperature range from -40 °C to +125 °C, ensuring reliable performance under varying thermal conditions.

Scrs Feature Summary

• High voltage blocking capability up to 1200 V for demanding power control circuits
• Robust 12 A RMS on-state current handling for heavy-duty loads
• Low gate trigger current requirement enabling direct drive from logic interfaces
• Industrial-grade thermal stability with extended operating temperature range

Scrs Applications

• Solid state relays requiring high isolation and switching reliability
• High power motor control systems for industrial automation
• AC power switching applications in general purpose converters

Scrs Procurement Notes

Verify the specific suffix RG against official STMicroelectronics documentation to confirm lead-free compliance and RoHS status. Ensure the ordering part number matches the exact voltage and current ratings required for the target circuit design. Cross-reference the datasheet revision date to confirm technical specifications have not been updated. Confirm package type compatibility with existing PCB footprints before procurement.

Scrs Selection Notes

Select this component when designing circuits that require high voltage isolation combined with moderate current handling capabilities. The TO-220AB package facilitates efficient heat dissipation for continuous operation. Consider the gate trigger sensitivity if interfacing directly with microcontroller outputs without additional driver stages. Evaluate thermal management requirements based on the ambient temperature and duty cycle of the intended application.

Scrs Part Context

The TYN series represents STMicroelectronics' line of general-purpose thyristors engineered for cost-effective power control solutions. These devices are widely utilized in industrial equipment where reliability and ruggedness are paramount. The TYN1212RG specifically targets applications needing 1200 V blocking voltage, distinguishing it from lower voltage variants within the same family.

Scrs Replacement Considerations

Consult official STMicroelectronics substitution guides for verified equivalents. Generic replacements may differ in gate sensitivity or thermal resistance. Verify that any substitute maintains the 1200 V rating and 12 A current capacity while fitting the TO-220AB footprint.
