Z0107SN 5AA4

Overview

The Z0107SN 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 rating of 1 A and a repetitive peak off-state voltage of 700 V. The device supports a non-repetitive surge current of up to 8.5 A at 50/60 Hz. Key electrical parameters include a maximum gate trigger voltage of 1.3 V and a maximum holding current of 10 mA. It operates within a junction temperature range of -40°C to +125°C and complies with RoHS3 standards.

Feature Summary

• Logic-sensitive gate architecture enables direct interfacing with microcontrollers and digital logic circuits without requiring high drive currents.
• Robust thermal and electrical performance allows reliable operation in high-temperature environments up to 125°C junction temperature.
• Compact SOT-223 surface-mount packaging facilitates automated assembly and space-efficient PCB layouts.

Applications

• Lighting control systems including dimmers and smart bulbs
• Solid-state relays for low-power switching applications
• Motor speed control circuits for small appliances

Procurement Notes

Verify the specific suffix 5AA4 against the manufacturer's latest datasheet to confirm pinout and marking consistency. Ensure the ordering quantity aligns with standard reel sizes as specified in official documentation. Cross-reference the component with authorized distributors to validate authenticity and traceability before integration into production schedules.

Selection Notes

Select this component when a 700 V blocking voltage and 1 A continuous current are required in a compact surface-mount form factor. The logic-sensitive gate characteristic simplifies driver circuit design compared to standard gate devices. Verify that the application's peak transient currents remain below the 8.5 A surge limit to ensure device reliability under operational stress conditions.

Part Context

This part belongs to the Z01 series of triacs from STMicroelectronics, which offers various voltage ratings and packages. The Z0107SN variant specifically provides 700 V blocking capability, distinguishing it from other series members like the Z0107NN (800 V) or Z0107MN (600 V). All variants share similar thermal characteristics and logical gate sensitivity profiles suitable for general-purpose AC switching tasks.

Replacement Considerations

Direct substitutes within the same series include Z0107NN 5AA4 for higher voltage tolerance or Z0107MN 5AA4 for lower voltage requirements. Ensure any replacement maintains the SOT-223 footprint and logic-sensitive gate specifications to preserve existing circuit board designs and driver compatibility without modification.
