Z0107MNT1G

Overview

The Z0107MNT1G is a four-quadrant logic level TRIAC manufactured by Littelfuse. It features a sensitive gate design suitable for direct interface with microcontrollers and logic circuits. The device is rated for a maximum repetitive peak off-state voltage of 600 V and an RMS on-state current of 1 A. It utilizes a TO-261AA (SOT-223) surface-mount package, specifically CASE 318E-04, which provides a compact form factor for high-density PCB layouts. The component is constructed with plastic/epoxy encapsulation and offers commercial certification.

Feature Summary

• Sensitive gate architecture enabling low-power logic control
• Four-quadrant triggering capability for universal AC applications
• Surface-mount TO-261AA package for automated assembly

Applications

• Lighting dimmer circuits
• Solid-state relay modules
• Motor speed control systems

Procurement Notes

Verify the manufacturer source carefully, as the part number appears in databases associated with Rochester Electronics and ON Semiconductor alongside Littelfuse. Confirm that the specific ordering suffix matches the intended manufacturer's datasheet to ensure correct electrical characteristics and pinout compatibility before finalizing procurement.

Selection Notes

Select this component when a 1 A load capacity and 600 V blocking voltage are required in a small SMD footprint. The sensitive gate characteristic simplifies driver circuit design by reducing the necessary trigger current. Ensure the thermal management strategy accounts for the power dissipation inherent in the TO-261AA package during continuous conduction.

Part Context

This device belongs to the family of logic-level TRIACs designed for replacing mechanical relays or standard TRIACs in space-constrained designs. The TO-261AA package is widely used in consumer electronics and industrial controls where board real estate is limited but reliable AC switching is essential.

Replacement Considerations

Check cross-reference data for equivalent parts from ON Semiconductor or Rochester Electronics if Littelfuse supply is constrained. Verify that any substitute maintains the same 600 V rating, 1 A current handling, and sensitive gate sensitivity to ensure functional interchangeability without redesign.
