MAC4DSN-1G

Triacs Overview

The MAC4DSN-1G is a surface-mount TRIAC from Littelfuse, housed in a DPAK-3 package. It features a peak repetitive off-state voltage of 800 V and an on-state RMS current rating of 4.0 A at 108°C. The device supports a peak non-repetitive surge current of 40 A with an I2t value of 6.6 A²sec. Electrical characteristics include a maximum gate trigger current (IGT) of 10 mA across three quadrants and a peak on-state voltage (VTM) of 1.6 V. Operating junction temperature ranges from -40°C to +125°C, with thermal resistance values of 3.5°C/W (junction-to-case) and 80°C/80°C/W (junction-to-ambient).

Triacs Feature Summary

• Designed for high-volume industrial and consumer applications including motor control, process control, and temperature regulation.
• Features a passivated die structure to ensure reliability and uniformity under varying operating conditions.
• Provides high immunity to commutating dv/dt, rated at 50 V/μs at 125°C, reducing false triggering risks.

Triacs Applications

• Motor control systems
• Process control circuits
• Temperature and light regulation

Triacs Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and shipping configuration. The datasheet lists distinct part numbers for tape-and-reel versus box packaging. Confirm Pb-free status and lead length specifications prior to procurement to ensure compatibility with assembly processes.

Triacs Selection Notes

Select the MAC4DSN-1G when an 800V blocking voltage is required for surface-mount designs. Ensure the application circuit accommodates the 4.0A RMS current rating at the expected case temperature. Verify that the gate drive capability meets the 10mA maximum trigger current specification across the required operating quadrants.

Triacs Part Context

This component belongs to the MAC4DSM/MAC4DSN family of surface-mount thyristors. The 'N' suffix specifically denotes the 800V voltage variant, distinguishing it from the 600V MAC4DSM counterpart. Both share identical physical dimensions and electrical characteristics except for the blocking voltage rating.

Triacs Replacement Considerations

MAC4DSM-1G serves as a direct functional substitute if the application voltage does not exceed 600V. Other DPAK-3 TRIACs with matching 4A ratings and sufficient voltage margins may be considered, provided pinout and thermal resistance requirements are met.
