Z0107NN 5AA4

Overview

The Z0107NN 5AA4 is a logic-level 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 800 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 current of 5 mA, 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.
• High voltage blocking capability allows reliable operation in mains-powered AC switching applications.
• Robust thermal performance supports continuous operation across a wide industrial temperature range.

Applications

• Lighting control systems including dimmers and smart bulbs
• Solid-state relays for low-power AC load switching
• General-purpose AC power control circuits

Procurement Notes

Verify the complete part number including the suffix 5AA4 to ensure correct packaging and compliance status. Confirm RoHS3 certification requirements against specific regional regulations. Check moisture sensitivity level (MSL 1) handling guidelines if storage conditions exceed specified limits. Validate that the SOT-223 footprint matches the target PCB design constraints.

Selection Notes

Select this component when a compact surface-mount solution is required for 1 A AC loads with 800 V blocking voltage. The logic-sensitive gate characteristic simplifies driver circuit design compared to standard gate triacs. Ensure the application current does not exceed the 1 A RMS rating under all operating conditions. Consider thermal management requirements given the small SOT-223 package size.

Part Context

This device belongs to the Z01 series of triacs from STMicroelectronics, which are widely used in consumer electronics and appliance control. The Z01 series offers various voltage ratings and package options to suit different power levels. The Z0107NN variant specifically targets applications requiring moderate voltage isolation and low gate drive power.

Replacement Considerations

Direct pin-compatible replacements within the same series include Z0107SN 5AA4 (700 V rating) or Z0109NN 5AA4 (600 V rating). Verify voltage ratings match application requirements before substitution. Other manufacturers' equivalents may require schematic review due to potential differences in gate sensitivity and thermal characteristics.
