ACT108W-600D,135

Overview

The ACT108W-600D,135 is a bidirectional thyristor (triac) manufactured by WeEn Semiconductors. It features an RMS on-state current of 800 mA and a rated repetitive off-state voltage of 600 V. The device exhibits a maximum on-state voltage of 1.3 V and a gate trigger voltage of 900 mV with a gate trigger current of 5 mA. It operates within a temperature range up to +125 C and utilizes an SC-73-4 surface-mount package.

Feature Summary

• Bidirectional AC power switching capability for alternating current control applications
• Compact SC-73-4 surface-mount package design for space-constrained PCB layouts
• Defined gate triggering characteristics enabling reliable turn-on at specified voltage and current thresholds

Applications

• AC power switching circuits
• Lighting dimmer controls
• Motor speed regulation systems

Procurement Notes

Verify the complete part number including the suffix ,135 during ordering to ensure correct reel packaging configuration. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Validate that the SC-73-4 footprint matches the target PCB design specifications exactly.

Selection Notes

Select this component when an 800 mA RMS current rating and 600 V blocking voltage are required in a small surface-mount form factor. Ensure the gate drive circuit can supply at least 5 mA at 900 mV to guarantee reliable triggering under all operating conditions.

Part Context

This triac belongs to the ACT series of power switches from WeEn Semiconductors. The series focuses on compact AC control solutions suitable for consumer electronics and appliance applications requiring efficient power management in minimal board space.

Replacement Considerations

Consult official cross-reference lists for verified substitutes. Ensure any replacement maintains identical voltage ratings, current handling capabilities, and package dimensions to preserve circuit functionality.
