ACTT2X-800E,127

Overview

The ACTT2X-800E,127 is a bidirectional thyristor (Triac) manufactured by WeEn Semiconductors. It features an RMS on-state current of 2 A and a non-repetitive peak on-state current of 15.4 A. The device supports a rated repetitive off-state voltage of 800 V with a maximum off-state leakage current of 10 uA at VDRM. Key electrical parameters include an on-state voltage of 2 V, a maximum holding current of 25 mA, a gate trigger voltage of 800 mV, and a gate trigger current of 10 mA. Designed for through-hole mounting in a TO-220F-3 package, it operates within a temperature range up to +125 C.

Feature Summary

• Provides bidirectional AC power switching capability suitable for general-purpose applications.
• Features a sensitive gate structure requiring low gate trigger current for efficient control.
• Offers robust thermal performance with a maximum junction temperature rating of +125 C.

Applications

• AC motor speed control circuits

Selection Notes

Select this component when a 2 A RMS Triac with 800 V blocking voltage is required in a through-hole package. Ensure the driving circuit can supply at least 10 mA gate current. Compare against higher current variants like the ACTT6G series if load requirements exceed 2 A RMS.

Part Context

This part belongs to the ACTT2X family of Triacs from WeEn Semiconductors. The family includes various current ratings and voltage classes packaged in TO-220F-3 formats. This specific model represents the 2 A / 800 V configuration within that standardized product line.

Replacement Considerations

Direct substitutes may include other 2 A, 800 V Triacs in TO-220F-3 packages such as the BTA16 or BTA20 series, provided gate characteristics and thermal limits are compatible. Verify pinout compatibility before substitution.
