Overview
The ACTT2S-800E,118 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 14 A. The device supports a rated repetitive peak 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 10 mA, a gate trigger voltage of 800 mV, and a gate trigger current of 10 mA. It operates within a temperature range up to +150°C and utilizes a DPAK (TO-252) surface-mount package.
Feature Summary
- Integrated self-protective clamping capabilities against low and high energy transients
- Logic-level sensitive gate design for direct microcontroller interfacing
- Surface-mountable plastic package optimized for automated assembly

Selection Notes
Select this component when a compact surface-mount solution is required for AC load control applications. Ensure the circuit design accommodates the 800 V blocking voltage and that the thermal management strategy supports operation up to 150°C junction temperature. Confirm that the gate drive circuitry can supply the specified 10 mA trigger current reliably under all operating conditions.
Part Context
This part belongs to the ACTT series of triacs from WeEn Semiconductors, which are designed for general-purpose AC power switching. The series offers various current ratings and packaging options to suit different power density requirements. The ACTT2S variant specifically targets applications needing moderate current handling in a small footprint.
Replacement Considerations
Direct pin-to-pin replacements may include other 2 A, 800 V triacs in TO-252 packages from manufacturers like STMicroelectronics or ON Semiconductor, provided their electrical characteristics match the original specifications.
