Overview
The Z0405ME 1AA2 is a Triac from the STMicroelectronics Z04 series, designed for AC power control applications. It features a rated repetitive off-state voltage (VDRM) of 600 V and an RMS on-state current (IT(RMS)) of 4.0 A. The device supports a non-repetitive peak surge current of 21 A at 50/60 Hz. Key electrical parameters include a maximum holding current of 25 mA, a gate trigger voltage of 1.3 V, and a gate trigger current of 5 mA. It operates within a junction temperature range of -40°C to +125°C and is housed in a TO-202 package.
Feature Summary
- Capable of controlling AC loads with a 4.0 A RMS on-state current rating
- Provides robust surge handling with a 21 A non-repetitive peak current capability
- Ensures reliable switching with low gate trigger requirements
Applications
- Lighting dimmers
- Motor speed controls
- Heating controllers
Procurement Notes
Verify component authenticity through authorized STMicroelectronics distributors or certified partners. Confirm that the specific suffix matches the required specifications. Check for end-of-life status or obsolescence notices prior to procurement. Ensure supply chain integrity to avoid counterfeit devices. Validate compliance with relevant environmental standards such as RoHS where applicable.
Selection Notes
Select this component for designs requiring 600 V blocking capability and 4 A continuous current handling. Consider the TO-202 package constraints for thermal management and PCB layout. Evaluate the gate trigger characteristics against the driving circuit capabilities. Compare performance metrics with alternative triacs if higher current ratings are needed.
Part Context
This part belongs to the Z04 family of general-purpose triacs by STMicroelectronics. These components are widely used in consumer electronics and industrial equipment for phase-angle control. The Z04 series offers a balance of performance and cost-effectiveness for standard AC switching tasks.
Replacement Considerations
Consult official substitution guides for equivalent triacs with matching VDRM and IT(RMS) ratings. Verify pinout compatibility and thermal resistance values when replacing. Cross-reference datasheets for gate sensitivity differences.
