Z0405MF0AA2

Overview

The Z0405MF0AA2 is a sensitive gate triac manufactured by STMicroelectronics, rated for 4 A RMS on-state current and 600 V repetitive peak off-state voltage. It utilizes the IPAK (TO-92) through-hole package with three pins. The device features a gate trigger current of 5 mA, enabling direct coupling to TTL, HTL, and CMOS logic circuits. It operates within a junction temperature range up to +125 °C and complies with ECOPACK2 environmental standards.

Feature Summary

• Sensitive gate architecture allows direct interface with standard digital logic families without additional driver components.
• Robust thermal design supports operation in high-temperature environments up to 125 °C junction temperature.
• Halogen-free molding and lead-free plating ensure compliance with RoHS directives and ECOPACK2 standards.

Applications

• Fan speed control systems
• Small light controllers
• Home appliance equipment

Procurement Notes

Verify the specific suffix '0AA2' against official STMicroelectronics documentation to confirm exact binning or packaging specifications. Ensure the ordering part number matches the required gate sensitivity class and package type before procurement to avoid functional mismatches.

Selection Notes

Select this component when a 4 A AC switching capability is required with low gate drive power. The sensitive gate characteristic simplifies circuit design by permitting direct microcontroller or logic gate interfacing. Verify that the 600 V blocking voltage meets the peak line voltage requirements of the target application.

Part Context

This device belongs to the Z04 series of triacs from STMicroelectronics, designed for general-purpose AC power control. The series offers various gate sensitivities to optimize performance for different control interfaces. The Z0405 variant specifically targets applications requiring moderate current handling with simplified driving electronics.

Replacement Considerations

Publicly documented substitutes include the 2N6075 and BT134-600 series triacs. Verify pinout compatibility and gate trigger current specifications when substituting to ensure proper circuit functionality.
