Z0402MF0AA2

Overview

The Z0402MF0AA2 is a four-quadrant triac manufactured by STMicroelectronics, rated for 600 V repetitive peak off-state voltage and 4 A average on-state current. It utilizes a TO-202 (IPAK) through-hole package with three leads. Key electrical parameters include a maximum holding current of 3 mA, a gate trigger current of 3 mA, and a gate trigger voltage of 1.3 V. The device supports a non-repetitive surge current of 21 A and operates within a junction temperature range of -40°C to +125°C.

Feature Summary

• Four-quadrant triggering capability ensures reliable gate activation across all polarity combinations of main terminal voltages and currents.

Applications

• Control circuits for home appliances
• Power tool motor drives
• Industrial system switching

Procurement Notes

Verify component authenticity against official STMicroelectronics documentation due to end-of-life status. Confirm package integrity and lead condition upon receipt. Cross-reference datasheet revisions to ensure compatibility with existing design specifications before integration into production workflows.

Selection Notes

Select this component when a robust through-hole solution is required for AC load control up to 4 A. The IPAK package offers thermal performance suitable for industrial environments. Ensure the circuit design accommodates the specified 600 V blocking voltage and 21 A surge rating for safety margins.

Part Context

This part belongs to the Z04 series of triacs designed for general-purpose AC switching applications. It shares functional similarities with other members of the family but is distinguished by its specific TO-202 packaging and 4 A current rating, targeting medium-power industrial and consumer electronics markets.

Replacement Considerations

The TS420-600H is listed as an available substitute from STMicroelectronics. Verify pinout compatibility and electrical parameter alignment before substitution.
