Z0103MA0,412

Overview

The Z0103MA0,412 is a four-quadrant logic level TRIAC manufactured by WeEn Semiconductors. It features an 800 V repetitive peak off-state voltage and a 1 A RMS on-state current rating. The device utilizes a sensitive gate structure designed for direct interfacing with logic-level integrated circuits. It is housed in a TO-92 plastic package, providing a compact solution for low-power switching applications requiring robust gate drive compatibility.

Feature Summary

• Four-quadrant triggering capability ensures reliable operation across all gate polarities and main terminal voltage states.
• Logic-level sensitivity allows direct interface with standard digital logic ICs without additional buffer drivers.
• Planar passivated construction provides enhanced stability and protection against environmental stress.

Applications

• Lighting control systems
• Small motor speed regulation
• Heater control circuits

Procurement Notes

Verify the specific manufacturer source, as this component is produced by both NXP Semiconductors and WeEn Semiconductors following corporate restructuring. Confirm that the ordering suffix matches the desired supplier to ensure consistency in datasheet specifications and quality standards during procurement.

Selection Notes

Select this component when an application requires a TRIAC with high gate sensitivity for direct logic interfacing. Ensure the circuit design accommodates the 800 V blocking voltage and 1 A continuous current limits. Verify thermal management requirements for the TO-92 package based on the expected power dissipation in the target environment.

Part Context

This part belongs to the Z0103 series of four-quadrant TRIACs. The series is characterized by its planar passivated structure and logic-level gate sensitivity. Variants within the series typically share similar electrical characteristics but may differ in packaging or specific manufacturing origin between NXP and WeEn.

Replacement Considerations

Cross-reference with other Z0103 series parts from different manufacturers. Verify pinout compatibility and electrical parameter equivalence, specifically regarding gate trigger current and holding current, before substituting.
