Overview
The Z0405MF 1AA2 is a 4 A Triac from the STMicroelectronics Z04 series, housed in a TO-202 (TO-92) through-hole package. It features a rated repetitive off-state voltage of 600 V and supports a maximum junction temperature of 125 °C. The device has a peak on-state voltage of 2 V and a holding current of 10 mA. Gate trigger parameters include a maximum gate trigger voltage of 1.3 V and a maximum gate trigger current of 10 mA. It is designed for AC load switching applications requiring robust performance in compact form factors.
Feature Summary
- Four-quadrant sensitivity ensures reliable triggering across all gate polarities and main terminal voltages.
- High surge current capability allows handling of transient loads typical in appliance and industrial drives.
- Halogen-free molding and lead-free plating comply with environmental standards such as ECOPACK2.
Applications
- AC motor speed control in home appliances
- Lighting dimmer circuits
- Solid-state relays
Procurement Notes
Verify the specific suffix '1AA2' against official STMicroelectronics documentation to confirm pinout orientation and compliance status. Ensure the procurement channel provides original manufacturer packaging or certified traceability documents. Cross-reference the part number with the latest datasheet revision to avoid obsolete variants.
Selection Notes
Select this component when a 4 A RMS current rating and 600 V blocking voltage are required in a TO-202 package. Compare gate trigger current requirements against the driving circuit capabilities, noting the 10 mA maximum limit. Consider thermal management constraints given the 125 °C junction temperature limit and the through-hole mounting style.
Part Context
This part belongs to the Z04 family of 4 A Triacs from STMicroelectronics. Similar devices include the Z0402MF 1AA2 and Z0409MF 1AA2, which share the same current and voltage ratings but may differ in gate sensitivity or specific manufacturing revisions. The Z04 series is widely used in general-purpose AC power control applications.
Replacement Considerations
Direct substitutes within the same series include Z0402MF 1AA2 and Z0409MF 1AA2. Verify pin compatibility and electrical parameter equivalence before substitution. Alternative packages like IPAK (Z0405MH) offer similar electrical characteristics but require different PCB layout considerations.
