MAC4DCMT4G

Triacs Overview

The Littelfuse MAC4DCMT4G is a bidirectional triac thyristor designed for surface-mount applications. It features a non-repetitive peak on-state current of 40 A and a rated repetitive off-state voltage (VDRM) of 600 V. The device exhibits an on-state voltage of 1.6 V, with a maximum holding current of 35 mA. Gate triggering requirements include a voltage of 1.3 V and a current of 35 mA. It operates within a temperature range of -40°C to +125°C and is housed in a DPAK-3 (TO-252-3) package.

Triacs Feature Summary

• Surface-mount construction in a DPAK-3 package for automated assembly
• Bidirectional AC switching capability with 600 V blocking voltage
• High surge current handling with 40 A non-repetitive rating
• Low gate trigger sensitivity for efficient driver interface

Triacs Applications

• AC power control circuits
• Lighting dimmer applications
• Motor speed control systems

Triacs Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm pinout and electrical tolerances. Ensure the procurement channel provides valid traceability data. Confirm RoHS compliance status through official Littelfuse declarations prior to integration into regulated assemblies.

Triacs Selection Notes

Select this component when a 600 V rating is required for AC loads. Compare gate trigger current specifications against available drive circuitry capabilities. Verify that the thermal management design supports the specified junction temperature limits during continuous operation.

Triacs Part Context

This part belongs to the MAC4D series of standard triacs manufactured by Littelfuse. It shares functional similarities with other devices in the family but differs in voltage ratings and package types. The MAC4DCNT4G serves as a higher voltage variant within the same product line.
