TOPT12-800C0,127

Overview

The TOPT12-800C0,127 is a planar passivated triac featuring integrated temperature and overload protection within a SOT78 (TO-220AB) plastic package. It offers an RMS current of 12 A and a repetitive peak off-state voltage of 800 V. The device provides a non-repetitive surge current capacity of 95 A with a maximum junction temperature of 150°C. Triggered negatively using continuous DC or current pulses, it includes self-protection mechanisms that turn the device off during excessive temperature events.

Feature Summary

• Integrated thermal and overload protection that automatically turns off the device during excessive temperature conditions
• Planar passivated construction designed for high commutation performance
• Negative triggering capability compatible with continuous DC or current pulse inputs

Applications

• Industrial circuits requiring high static and dynamic dv/dt immunity
• Applications necessitating overload protection without external components
• High commutation power switching environments

Procurement Notes

Verify the specific ordering suffix against official WeEn Semiconductors documentation to confirm package orientation and packing method. Ensure the selected variant matches the required industrial qualification standards. Cross-reference the 12NC code with current datasheets to validate RoHS compliance and lead-free status before procurement.

Selection Notes

Select this component when circuit designs require inherent thermal shutdown capabilities to prevent damage from overload conditions. The negative trigger logic must align with the control interface design. Verify that the 12 A RMS rating and 800 V blocking voltage meet the specific load requirements of the target application.

Part Context

This part belongs to the TOPTriac family, which integrates protection features into standard thyristor packages. It serves as a robust solution for industrial power control where reliability under fault conditions is critical. The TO-220AB form factor allows for standard mounting solutions while providing the necessary electrical isolation and thermal management.

Replacement Considerations

Direct substitutes are not explicitly listed in the provided data. Evaluate other TOPTriac variants within the same family for similar protection profiles. Standard triacs lacking integrated thermal protection may serve as functional replacements if external safeguards are implemented.
