TN1215-600H

Scrs Overview

The TN1215-600H is a standard recovery silicon controlled rectifier (SCR) manufactured by STMicroelectronics. It features an on-state RMS current rating of 12 A and repetitive peak off-state voltages available in 600 V, 800 V, and 1000 V variants. The device utilizes a TO-251 (IPAK) through-hole package for robust mounting. Key electrical parameters include a gate trigger current of 5 mA or 15 mA depending on the specific sub-type, with a holding current of 40 mA. It operates within a junction temperature range of -40°C to 125°C.

Scrs Feature Summary

• Standard recovery thyristor design suitable for general-purpose power control applications
• Through-hole IPAK packaging provides mechanical stability and thermal dissipation
• Sensitive gate triggering capability allows for efficient control circuit integration

Scrs Applications

• Industrial motor speed control systems
• Lighting dimmer circuits
• General purpose AC power switching

Scrs Procurement Notes

Verify the exact voltage variant (600V, 800V, or 1000V) required for your circuit design, as the base part number may refer to a series. Confirm the specific gate trigger current specification (5mA vs 15mA) if sensitive gate operation is critical. Ensure the TO-251 footprint matches your PCB layout requirements. Check RoHS compliance status for environmental regulations.

Scrs Selection Notes

Select this component when a 12A RMS current capacity is needed in a through-hole form factor. Consider the IPAK package for better heat dissipation compared to smaller surface-mount alternatives. Evaluate the gate trigger sensitivity against your driving circuit's output capabilities. Ensure the selected voltage rating exceeds the maximum peak reverse voltage in the application.

Scrs Part Context

This SCR belongs to STMicroelectronics' family of sensitive and standard thyristors designed for medium-power applications. The TN1215 series offers reliable performance in industrial environments. The IPAK package distinguishes it from surface-mount options, providing a traditional mounting solution for legacy or high-reliability designs requiring through-hole assembly.

Scrs Replacement Considerations

Check for direct equivalents such as the TN1215-800H or TN1215-1000H for higher voltage ratings within the same current and package family. Verify compatibility with other manufacturers' 12A IPAK SCRs by comparing IT(RMS), VDRM, and IGT specifications.
