TXN612RG

Scrs Overview

The TXN612RG is a standard recovery Silicon Controlled Rectifier (SCR) manufactured by STMicroelectronics. It features a maximum repetitive peak off-state voltage of 600 V and an on-state RMS current rating of 12 A. The device is housed in a TO-220AB insulated package with three leads, suitable for through-hole mounting. Key electrical characteristics include a maximum gate trigger current of 25 mA and a maximum on-state voltage of 1.4 V. It operates within a junction temperature range of -40°C to +125°C.

Scrs Feature Summary

• Insulated TO-220AB package enables back-to-back configuration without additional insulating hardware
• Standard recovery type optimized for general-purpose AC switching applications
• High surge current capability provided by clip assembly technology

Scrs Applications

• Voltage regulation circuits for motorbikes
• Overvoltage crowbar protection systems
• Motor control circuits in power tools and kitchen aids
• Inrush current limiting circuits
• Capacitive discharge ignition systems

Scrs Procurement Notes

Verify the specific part number suffix against official STMicroelectronics documentation to confirm pinout and insulation specifications. Ensure the procurement source provides valid RoHS compliance certificates. Cross-reference the datasheet TN1215 or TYNx12 series documents for accurate thermal and electrical limits before finalizing orders.

Scrs Selection Notes

Select this component for applications requiring robust surge handling and electrical isolation in a single package. The insulated TO-220AB design simplifies heatsinking and mounting compared to non-insulated variants. Consider the 25 mA gate trigger requirement when designing the driving circuitry to ensure reliable turn-on under varying temperature conditions.

Scrs Part Context

This device belongs to the TYN/TXN series of standard SCRs from STMicroelectronics. These components are designed for high-reliability industrial and consumer applications. The TXN variant typically denotes specific packaging or insulation characteristics within the broader SCR portfolio, sharing core electrical performance metrics with similar rated devices like the TYN612.

Scrs Replacement Considerations

Direct substitutes may include the TYN612RG or TYN612M, though package insulation differences must be verified. Check equivalent parts from other manufacturers with matching 600V/12A ratings and TO-220AB insulated footprints. Confirm that gate trigger currents and surge capabilities meet or exceed original design requirements.
