Overview
The Z0409MB is a 4 A Triac manufactured by STMicroelectronics, housed in a compact surface-mount DPAK package. It features a maximum repetitive peak off-state voltage of 600 V and a non-repetitive peak surge current rating of 21 A. The device operates with a maximum gate trigger current of 10 mA and supports a junction temperature range from -40 °C to +125 °C. It complies with ECOPACK2 standards, utilizing halogen-free molding and lead-free plating for environmental safety.
Feature Summary
- Four-quadrant triggering capability ensures reliable operation across all gate signal polarities.
- Surface-mount DPAK packaging enables automated manufacturing and space-efficient circuit board designs.
- ECOPACK2 compliance guarantees the use of halogen-free molding compounds and lead-free plating.
Applications
- Home appliances requiring AC load switching
- Power tools with compact form factor constraints
- Industrial systems driving loads up to 4 A
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official documentation to confirm pinout orientation and electrical tolerances. Ensure that the procurement channel provides traceable components compliant with the stated ECOPACK2 environmental standards. Cross-reference the part number with the latest datasheet revision to confirm availability and any potential design changes.
Selection Notes
Select this component when a surface-mount TRIAC is required for AC switching applications with currents up to 4 A. The DPAK package is suitable for automated assembly processes where board space is limited. Verify that the application voltage does not exceed the 600 V rating and that the thermal management strategy accommodates the specified junction temperature limits.
Part Context
This component belongs to the Z0409 series of TRIACs offered by STMicroelectronics. While other variants in the series utilize through-hole packages such as IPAK or TO-202, the Z0409MB specifically utilizes the DPAK surface-mount format. This variation maintains the core electrical characteristics of the series while adapting the physical interface for modern PCB technologies.
Replacement Considerations
Direct replacements include other Z0409 series devices like the Z0409MH if through-hole mounting is acceptable. For surface-mount equivalents, verify compatibility with the DPAK footprint and ensure the replacement device meets the 4 A RMS current and 600 V blocking voltage requirements.
