TYN058RG

Scrs Overview

The TYN058RG is a standard Silicon Controlled Rectifier (SCR) manufactured by STMicroelectronics, belonging to the TYN408 series. It features an 8.0 A on-state RMS current rating and supports repetitive peak off-state voltages ranging from 200 V to 1200 V. The device utilizes a TO-220AB insulated package for through-hole mounting, providing superior surge current capabilities via clip assembly technology. Key electrical parameters include a maximum holding current of 45 mA, a non-repetitive peak on-state current of 84 A, and a gate trigger voltage of 1.5 V with a trigger current of 25 mA. It operates within a temperature range of -40°C to +125°C.

Scrs Feature Summary

• Utilizes clip assembly technology to deliver high performance in surge current handling capabilities.
• Features an insulated TO-220AB package design suitable for applications requiring thermal isolation.
• Offers highly sensitive gate triggering characteristics to facilitate control with limited gate drive currents.

Scrs Applications

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

Scrs Procurement Notes

Verify the specific voltage sub-grade suffix when ordering, as the TYN408 series encompasses multiple blocking voltage options. Confirm that the required insulation class and thermal management solutions align with the TO-220AB insulated package specifications. Ensure the selected variant meets the necessary regulatory certifications for the target market.

Scrs Selection Notes

Select this component based on the required RMS current and peak off-state voltage ratings for the specific application. Consider the thermal dissipation requirements associated with the TO-220AB package and the ambient operating temperature limits. Evaluate the gate trigger sensitivity against the available drive circuit capabilities to ensure reliable turn-on.

Scrs Part Context

This SCR belongs to the TYN408 family of standard thyristors designed for robust industrial and commercial use. The series is characterized by its ability to handle high surge currents and its availability in insulated packages. These devices are engineered for reliability in environments demanding stable switching performance under varying load conditions.

Scrs Replacement Considerations

Compatible substitutes include other 8A SCRs in TO-220AB insulated packages from major manufacturers, provided they match the voltage rating and pinout configuration. Verify equivalent thermal resistance and gate trigger parameters before implementation.
