Overview
The Z0109SN 5AA4 is a logic-sensitive gate triac manufactured by STMicroelectronics, designed for surface-mount applications in the SOT-223 package. It features an RMS on-state current of 1 A and a non-repetitive peak on-state current of 8.5 A. The device supports a rated repetitive off-state voltage (VDRM) of 800 V with a maximum off-state leakage current of 5 uA at VDRM. Key electrical parameters include an on-state voltage of 1.56 V, a maximum holding current of 10 mA, and a gate trigger voltage of 1.3 V with a gate trigger current of 10 mA. It operates within a junction temperature range of -40°C to +125°C.
Feature Summary
- Logic-sensitive gate architecture enables direct interfacing with microcontrollers and digital logic circuits without requiring high drive currents.
- High thermal stability and robust construction support reliable operation in demanding industrial environments across a wide temperature range.
Applications
- Solid-state relays
- Industrial motor control systems
- Lighting dimmers
Procurement Notes
Verify the specific suffix '5AA4' against official STMicroelectronics documentation to confirm pinout configuration and compliance status. Ensure the ordering part number matches the required voltage rating and package type before procurement. Cross-reference datasheet revisions to validate parameter consistency.
Selection Notes
Select this component when a 1 A RMS current capacity and 800 V blocking voltage are required in a compact SMD form factor. The logic-sensitive gate characteristic simplifies driver circuit design compared to standard gate devices. Confirm that the SOT-223 thermal dissipation capabilities meet the application's power requirements.
Part Context
This device belongs to the Z01 series of triacs from STMicroelectronics, which are widely used in AC switching applications. The Z01 series offers various voltage ratings and gate sensitivities to accommodate different load types and control interface constraints.
Replacement Considerations
Publicly confirmed substitute part numbers for Z0109SN 5AA4 were not identified in the provided source material. Verify compatibility with alternative triacs based on matching electrical specifications and package dimensions.
