Z0110MN 5AA4

Overview

The Z0110MN 5AA4 is a bidirectional triac manufactured by STMicroelectronics, designed for surface-mount applications in the SOT-223 package. It features a rated RMS on-state current of 1 A and a repetitive peak off-state voltage of 800 V. The device supports a non-repetitive peak on-state current of 8.5 A and operates within a junction temperature range of -40°C to +125°C. Key electrical parameters include a maximum holding current of 10 mA, a gate trigger voltage of 1.3 V, and a gate trigger current of 10 mA. The on-state voltage is specified at 1.56 V, with an off-state leakage current of 5 uA under rated voltage conditions.

Feature Summary

• High-voltage blocking capability suitable for mains-connected loads
• Logic-level sensitive gate triggering for direct microcontroller interfacing
• Robust thermal performance across extended industrial temperature ranges

Applications

• Solid-state relay modules
• AC motor speed control circuits
• Lighting dimmer switches

Procurement Notes

Verify the specific suffix '5AA4' against official STMicroelectronics documentation to confirm pinout and marking details. Ensure the ordering part number matches the exact voltage and current ratings required for the target application. Cross-reference datasheet revisions to confirm compliance with current environmental standards before finalizing procurement specifications.

Selection Notes

Select this component when an 800 V rating is necessary for higher voltage AC lines compared to standard 600 V variants. The SOT-223 package offers a compact footprint for high-density PCB layouts while providing adequate thermal dissipation for 1 A continuous loads. Confirm that the gate trigger characteristics align with the driving circuit's output capabilities to ensure reliable switching.

Part Context

This device belongs to the Z01 series of logic-sensitive triacs from STMicroelectronics. The series provides integrated solutions for controlling AC power in consumer and industrial electronics. The Z0110 variant specifically addresses applications requiring higher voltage isolation than lower-rated counterparts, maintaining compatibility with standard surface-mount assembly processes.

Replacement Considerations

Check for Z0109NN or Z0110NN equivalents if through-hole mounting is required. Verify pinout compatibility with existing board designs when substituting with other 800 V, 1 A triacs from different manufacturers.
