MAC4DSMT4

Triacs Overview

The MAC4DSMT4 is a silicon bidirectional thyristor (TRIAC) from the MAC4DSM series, designed for industrial and consumer applications. It features a DPAK-3 surface mount package with a peak repetitive off-state voltage of 600 V and an on-state RMS current rating of 4.0 A at a case temperature of 108°C. The device supports a peak non-repetitive surge current of 40 A and operates within a junction temperature range of -40°C to 125°C. Key electrical characteristics include a maximum gate trigger current of 10 mA in three quadrants and a critical rate of rise of off-state voltage of 50 V/µs at 125°C.

Triacs Feature Summary

• Small size surface mount DPAK package
• Passivated die for reliability and uniformity
• High immunity to dv/dt
• ESD ratings: Human Body Model 8000 V, Machine Model 400 V

Triacs Applications

• Motor control
• Process control
• Temperature control
• Light control
• Speed control

Triacs Procurement Notes

Verify the specific ordering suffix to confirm the shipping configuration. The MAC4DSMT4 designation corresponds to the standard tape and reel packaging format containing 2500 units per reel. Confirm that the required variant matches the intended manufacturing process and handling requirements before finalizing procurement orders.

Triacs Selection Notes

Select this component when a 600 V blocking voltage and 4.0 A RMS current capability are required in a compact surface mount form factor. Ensure the application circuit accounts for the thermal resistance values provided, specifically the junction-to-case and junction-to-ambient ratings, to maintain operation within the specified temperature limits under expected load conditions.

Triacs Part Context

This part belongs to the MAC4DSM family of TRIACs manufactured by onsemi. The 'T4' suffix indicates the specific tape and reel packaging configuration. The base device offers a 600 V rating, while the MAC4DSN variant provides an 800 V rating within the same physical package and electrical current specifications.

Triacs Replacement Considerations

MAC4DSNT4 serves as the direct replacement for higher voltage requirements within the same package. Other compatible alternatives include MAC4DSM-001G for rail packaging needs or generic equivalents such as MAC4DLMT4G if pin compatibility and electrical ratings align with the design constraints.

Triacs FAQ
