Overview
The Z0409MH is a four-quadrant triac rated for 4 A average on-state current, housed in a compact through-hole IPAK package. It supports a repetitive peak off-state voltage of 600 V and a surge voltage of 750 V. The device features a maximum gate trigger current of 10 mA and a peak on-state voltage of 2 V. It operates within a junction temperature range of -40 °C to +125 °C. The component complies with ECOPACK2 standards, utilizing halogen-free molding and lead-free plating.
Feature Summary
- Four-quadrant sensitivity enabling reliable triggering across all voltage polarities
- High thermal stability supporting operation up to 125 °C junction temperature
- RoHS-compliant construction with halogen-free molding and lead-free plating
Applications
- Home appliances requiring AC load switching
- Power tools utilizing high-current motor control
- Industrial systems driving loads up to 4 A
Procurement Notes
Verify the specific suffix '1AA2' against official STMicroelectronics documentation to confirm pinout and marking consistency. Ensure the IPAK package variant matches the required PCB footprint. Confirm compliance with ECOPACK2 environmental standards if restricted substances are mandated by the target application regulations.
Selection Notes
Select this component when a through-hole solution is required for 4 A AC loads. The 600 V rating suits standard mains applications. Compare with the Z0409MB SMD variant if space constraints favor surface mount technology. Verify that the 10 mA gate trigger current aligns with the available drive circuit capability.
Part Context
This part belongs to the Z0409 series of 4 A triacs from STMicroelectronics. It shares electrical characteristics with the Z0409MF and Z0409MB but differs in packaging. The MH suffix specifically denotes the IPAK through-hole package, distinguishing it from the MF (TO-202) and MB (DPAK) variants.
Replacement Considerations
The Z0409MB serves as a functional equivalent in DPAK format. The Z0409MF offers identical electrical performance in TO-202 packaging. Cross-referencing datasheets is necessary to verify pin compatibility and thermal dissipation requirements for direct substitution.
