Overview
The ACT108W-600E,135 is a bidirectional thyristor (TRIAC) manufactured by WeEn Semiconductors in the SC-73-4 package. It features an RMS on-state current of 800 mA and a non-repetitive peak on-state current of 8.8 A. The device has a rated repetitive off-state voltage of 600 V and a maximum holding current of 20 mA. Gate trigger voltage is specified at 900 mV with a gate trigger current of 5 mA. The on-state voltage is 1.3 V, and leakage current is 2 uA. It operates within a temperature range up to +125 C.
Feature Summary
- Surface-mount TRIAC designed for AC power switching applications
- Sensitive gate structure enabling reliable triggering with low gate current
- High thermal stability supporting operation up to 125 C
Applications
- Light dimmer circuits
- Motor speed control systems
- Solid state relay modules
Procurement Notes
Verify the specific suffix '135' indicates the reel packaging configuration as documented in official component specifications. Confirm RoHS compliance status through the manufacturer's latest certification documents. Ensure the SC-73-4 footprint matches the target PCB design requirements before finalizing procurement orders.
Selection Notes
Select this component when a compact surface-mount TRIAC is required for moderate current loads up to 800 mA. The 600 V rating suits general purpose AC line applications. Consider the 5 mA gate trigger current for driver compatibility. Compare against the ACT108W-600D variant if different gate characteristics are needed.
Part Context
This part belongs to the ACT108W series of logic-level sensitive gate TRIACs from WeEn Semiconductors. It shares the SC-73-4 package form factor with other devices in the family but differs in electrical ratings such as gate trigger parameters. The series targets space-constrained consumer electronics and industrial control boards requiring reliable AC switching.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Verify pinout compatibility and thermal performance if considering alternative manufacturers or similar rated devices from other suppliers.
