TOPT16-800C0,127

Overview

The TOPT16-800C0,127 is a planar passivated triac featuring integrated temperature and overload protection within a SOT78 (TO-220AB) plastic package. It offers an RMS on-state current of 16 A and a non-repetitive peak on-state current of 140 A. The device supports a rated repetitive peak off-state voltage of 800 V with a maximum junction temperature of +150°C. Triggering is performed negatively using continuous DC or current pulses. Key gate parameters include a maximum gate trigger current of 35 mA in quadrants Q2 and Q3, and a static dv/dt rating of 500 V/µs.

Feature Summary

• Integrated thermal protection mechanism that automatically turns off the device during excessive temperature events to prevent damage.
• Planar passivated construction designed for high commutation performance and robust operation under high di/dt conditions.
• Negative triggering capability compatible with standard DC or pulsed gate drive signals.

Applications

• Industrial motor control systems requiring high commutation reliability
• High-temperature power switching applications exceeding standard junction limits
• AC power regulation circuits utilizing negative gate triggering

Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm package orientation and packing method. Confirm RoHS compliance status and lead-free conversion dates via official datasheets before procurement. Ensure the selected variant matches the required industrial qualification standards for the target application environment.

Selection Notes

Select this component when applications demand self-protection against thermal overload without external circuitry. The 16 A RMS rating suits moderate-to-high power AC loads. Verify that the negative triggering logic aligns with the available gate drive interface. The TO-220AB package facilitates effective heat dissipation for sustained high-current operations.

Part Context

This part belongs to the TOPTriac family from WeEn Semiconductors, distinguished by its built-in thermal shutdown feature. Unlike standard triacs, it actively manages thermal stress by turning off during overheating. It utilizes a SOT78 physical footprint while providing enhanced safety margins for industrial thyristor applications.

Replacement Considerations

Direct replacements must match the 16 A RMS current, 800 V blocking voltage, and integrated thermal protection functionality. Standard triacs lacking self-protection require additional thermal monitoring circuits. Verify gate trigger polarity compatibility, as this device requires negative triggering.
