ACTT2W-800ETNF

Overview

The ACTT2W-800ETNF is a planar passivated triac from WeEn Semiconductors, designed for high-temperature power switching applications. 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 peak off-state voltage (VDRM) of 800 V with a maximum off-state leakage current of 10 uA at VDRM. Key electrical parameters include a gate trigger voltage (VGT) of 800 mV and a gate trigger current (IGT) of 10 mA. The component operates within a temperature range of -40°C to +125°C and utilizes the SC-73 surface-mount package.

Feature Summary

• Planar passivated construction ensures robust performance and reliability in demanding environments.
• High commutation capability allows for efficient switching in AC power control circuits.
• Three-quadrant triggering simplifies gate drive circuit design by accepting positive or negative gate signals.

Applications

• Solid state relays
• Motor speed control systems
• Lighting dimmers

Procurement Notes

Verify the specific ordering suffix ETNF to confirm the SC-73 surface-mount package configuration. Ensure that the procurement channel provides official datasheets confirming the 800 V blocking voltage and 2 A current ratings. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and compliance with RoHS standards before finalizing orders.

Selection Notes

Select this component when a compact surface-mount solution is required for low-power AC switching tasks. The 2 A RMS rating suits light loads, while the 800 V voltage class provides adequate margin for standard mains voltages. Consider the SC-73 footprint constraints and thermal management requirements inherent to small-outline packages during PCB layout.

Part Context

This triac belongs to the ACTT series of enhanced power switches optimized for modern electronics. It complements through-hole alternatives like the ACTT2X-800E by offering a smaller form factor suitable for automated assembly. The product line emphasizes high temperature stability and noise immunity for consumer and industrial appliances.

Replacement Considerations

Direct pin-compatible replacements within the same package family should be verified against the 800 V and 2 A specifications. Alternative surface-mount triacs must match the SC-73 outline dimensions and thermal characteristics to ensure seamless integration without redesigning the host circuit board.
