Z0103NA 2AL2

Overview

The Z0103NA 2AL2 is a logic-level sensitive gate TRIAC manufactured by STMicroelectronics, designed for AC switching applications. It features a peak repetitive off-state voltage of 600 V and an RMS on-state current rating of 1 A. The device operates within a junction temperature range of -40°C to +125°C and is housed in a TO-92-3 through-hole package. Key electrical characteristics include a maximum gate trigger current of 3 mA and a holding current of 7 mA, enabling direct interface with microcontroller outputs.

Feature Summary

• Logic-sensitive gate architecture allows direct drive from standard logic families
• High thermal stability supports operation up to 125°C junction temperature
• Robust 600 V blocking capability suitable for general AC mains loads

Applications

• Solid-state relay modules
• Lighting control circuits
• Motor speed controllers

Procurement Notes

Verify the specific suffix '2AL2' against official STMicroelectronics documentation to confirm tape-and-reel packaging or specific marking variations. Ensure compatibility with RoHS 3 standards as indicated for the Z01 series. Cross-reference distributor part numbers to avoid confusion with similar Z0103 variants.

Selection Notes

Select this component when a low-power TRIAC is required for driving resistive or inductive loads up to 1 A. The logic gate sensitivity reduces driver circuit complexity compared to standard gate devices. Confirm that the 600 V rating meets the peak line voltage requirements of the target application.

Part Context

This part belongs to the Z01 series of TRIACs from STMicroelectronics, which includes various voltage and current ratings. The Z0103 variant specifically denotes the 1 A / 600 V class within this family, sharing common pinouts and thermal characteristics with other members like the Z0103MA.

Replacement Considerations

Check for exact pin-compatible substitutes such as the Z0103MA 1AA2. Verify that alternative parts maintain the same logic gate sensitivity and TO-92-3 package dimensions to ensure mechanical fit without PCB redesign.
