Triacs datasheet and documents for MAC218A8
Triacs Overview
The MAC218A8 is an 8 Ampere RMS TRIAC manufactured by onsemi, designed for high-power switching applications. It features a 600V repetitive peak off-state voltage and operates within a junction temperature range of -40°C to +125°C. The device utilizes a TO-220AB flange mount package with through-hole terminals, ensuring robust thermal dissipation. Key electrical parameters include a maximum DC gate trigger current of 50 mA, a maximum DC gate trigger voltage of 2 V, and a maximum holding current of 50 mA. The component exhibits a maximum repetitive peak off-state leakage current of 10 µA at the rated voltage.
Triacs Feature Summary
- High current handling capability suitable for demanding power control loads
- Robust thermal management via isolated flange mount construction
- Sensitive gate triggering compatible with standard logic interfaces
Triacs Applications
- Motor speed control systems
- Industrial heating element regulation
- Solid-state relay modules
Triacs Procurement Notes
Verify the specific manufacturer source, as the MAC218 series originated from Motorola/NXP. Confirm that the onsemi version maintains identical pinout and electrical specifications to ensure direct compatibility in existing designs. Check for RoHS compliance status and lead-free conversion dates relevant to your supply chain requirements.
Triacs Selection Notes
Select this component when an 8A RMS current rating and 600V blocking voltage are required in a flange-mountable package. Ensure the application environment supports the specified 125°C maximum junction temperature. Verify that the gate drive circuit can provide the necessary 50 mA trigger current under all operating conditions.
Triacs Part Context
This part belongs to the MAC218 family of 8 Ampere TRIACs, which offers various voltage ratings ranging from 200V to 800V. The MAC218A8 specifically addresses the 600V segment of this lineup. These devices are engineered for industrial and commercial power control applications requiring reliable switching performance and thermal stability.
Triacs Replacement Considerations
Direct substitutes include the MAC218-8-D1 and MAC218A8-N. Both parts share the same 8A RMS current rating, 600V voltage rating, and TO-220AB flange mount package configuration. Verify gate trigger characteristics match before finalizing any substitution.
