TN1215-600G

Scrs Overview

The TN1215-600G is a standard recovery Silicon Controlled Rectifier (SCR) manufactured by STMicroelectronics. It features an 800 V repetitive peak off-state voltage and a 12 A root-mean-square on-state current rating. The device utilizes a D2PAK surface-mount package with three pins, including a central thermal pad for efficient heat dissipation. Key electrical characteristics include a maximum gate trigger current of 15 mA and a maximum holding current of 30 mA. It operates within a junction temperature range of -40°C to 125°C.

Scrs Feature Summary

• Standard recovery type suitable for general-purpose AC switching applications
• Low thermal resistance design utilizing clip bonding technology
• Surface mount construction in a D2PAK package for automated assembly

Scrs Applications

• Static relay circuits
• Heating regulation systems
• Induction motor starting circuits

Scrs Procurement Notes

Verify the specific voltage rating against project requirements, as datasheets often list the TN1215 series with varying voltage codes such as 600V or 800G suffixes. Confirm the package variant matches the PCB footprint, specifically the D2PAK form factor. Ensure compliance with RoHS directives if required by the manufacturing environment. Cross-reference the manufacturer part number with distributor listings to confirm availability and authenticity before ordering.

Scrs Selection Notes

Select this component for applications requiring robust AC power control with moderate current handling capabilities. The low gate trigger current facilitates easy interfacing with logic-level drivers. Consider the thermal management requirements associated with the D2PAK package when designing the printed circuit board layout. Evaluate the standard recovery speed against the operating frequency to ensure adequate performance without excessive switching losses.

Scrs Part Context

This SCR belongs to the TN1215 family from STMicroelectronics, designed for industrial and consumer mains power switching. The series offers various voltage ratings to suit different line voltages. The D2PAK packaging provides a compact solution for high-current applications where space constraints exist. This component serves as a reliable alternative to through-hole equivalents in modern surface-mount designs.

Scrs Replacement Considerations

Compatible substitutes include other 12A SCRs in D2PAK packages from manufacturers like Littelfuse or IXYS. Verify that replacement parts match the 800V rating and 15mA gate trigger specifications. Ensure the thermal resistance and pinout configuration are identical to maintain PCB compatibility.
