Z0107NA 5AL2

Overview

The Z0107NA 5AL2 is a bidirectional triac manufactured by STMicroelectronics, designed for AC power switching applications. It features a rated RMS on-state current of 1 A and supports a repetitive peak reverse voltage of 600 V. The device utilizes a sensitive gate configuration with a maximum gate trigger current of 25 mA and a maximum gate trigger voltage of 1.3 V. It is housed in a surface-mount SOT-223 package with four pins, measuring 6.7 mm in length and 1.8 mm in height. The component operates within a junction temperature range of -40°C to +125°C and withstands an 8.5 A non-repetitive surge current.

Feature Summary

• Sensitive gate architecture enabling reliable triggering with low drive currents
• Surface-mount SOT-223 packaging optimized for automated assembly and compact board layouts
• High thermal stability supporting operation up to 125°C junction temperature

Applications

• Solid-state relay circuits requiring compact form factors
• General-purpose AC load switching in consumer electronics
• Motor speed control interfaces for small appliances

Procurement Notes

Verify the specific ordering suffix '5AL2' against official STMicroelectronics documentation to confirm the exact reel quantity and tape specifications. Ensure that the procurement channel provides traceable components compliant with RoHS standards. Cross-reference the manufacturer part number with distributor databases to validate authenticity and avoid counterfeit risks during sourcing.

Selection Notes

Select this component when a 1 A RMS current rating and 600 V blocking voltage are sufficient for the target AC load. The SOT-223 package is suitable for designs prioritizing surface-mount technology over through-hole alternatives. Confirm that the application circuit can provide at least 25 mA of gate current to ensure consistent turn-on characteristics under varying temperature conditions.

Part Context

This triac belongs to the Z01 series from STMicroelectronics, which focuses on standard and sensitive gate thyristors for general AC control. The Z01 family is widely utilized in household appliances and industrial controls due to its robust performance and standardized pinouts. The Z0107NA variant specifically addresses needs for moderate current handling in space-constrained printed circuit board designs.

Replacement Considerations

Direct replacements include other STMicroelectronics Z01 series devices such as the Z0107MUF or Z0107NN, provided the package type and electrical ratings match the design requirements. Verify compatibility with alternative manufacturers like Toshiba or Microsemi if supply constraints exist, ensuring identical gate trigger parameters and thermal characteristics.
