Triacs datasheet and documents for MAC228A6TG
Triacs Overview
The MAC228A6TG is a bidirectional thyristor (triac) manufactured by Littelfuse, designed for AC power control applications. It features an 8 A on-state RMS current rating and supports a repetitive peak off-state voltage (VDRM) of 600 V. The device utilizes a sensitive gate structure with a maximum gate trigger voltage (VGT) of 1.3 V and a maximum gate trigger current (IGT) of 75 mA. It operates within a junction temperature range of -40 °C to +125 °C and is housed in an isolated TO-220AB package.
Triacs Feature Summary
- Sensitive gate architecture enables direct interfacing with microprocessor drivers and logic circuits without requiring high drive currents.
Triacs Applications
- Solid state relays
- Motor speed controls
- Lighting dimmers
Triacs Procurement Notes
Verify the specific suffix 'G' against the manufacturer's datasheet to confirm RoHS compliance status and lead time requirements. Ensure the ordering quantity aligns with the manufacturer's standard tube packaging specifications rather than assuming reel quantities.
Triacs Selection Notes
Select this component when an 8 A load capacity at 600 V is required alongside low gate sensitivity. The TO-220AB package provides electrical isolation from the mounting surface, simplifying thermal management and mechanical installation in industrial enclosures.
Triacs Part Context
This part belongs to the MAC228 series of triacs, which are engineered for general-purpose AC switching. The series offers various voltage ratings and current capacities, with the MAC228A6TG representing the 600 V, 8 A variant optimized for sensitive gate triggering.
Triacs Replacement Considerations
Consult official substitution guides for equivalent parts such as the MAC228A6 or other 600 V, 8 A sensitive gate triacs. Verify pinout compatibility and thermal resistance parameters before implementing any cross-brand replacement.
