Z0103NA 5AL2

Overview

The Z0103NA 5AL2 is a logic-level sensitive gate TRIAC manufactured by STMicroelectronics, designed for AC switching applications. It features a 600 V repetitive peak off-state voltage and an RMS on-state current 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 (TO-226AA) through-hole package. Key electrical parameters include a maximum gate trigger current of 3 mA, a holding current of 7 mA, and a gate trigger voltage of 1.3 V. Non-repetitive surge currents are rated at 8 A for 50 Hz and 8.5 A for 60 Hz frequencies.

Feature Summary

• Logic-sensitive gate architecture enabling direct interface with digital logic circuits such as microcontrollers and optocouplers.
• Robust thermal performance supporting operation up to 125°C junction temperature for industrial environments.
• High surge current capability providing resilience against transient overloads during turn-on events.

Applications

• Universal motor speed control systems
• Solid-state relay modules
• Lighting dimmer circuits

Procurement Notes

Verify the specific suffix '5AL2' against the manufacturer's official datasheet to confirm packaging type and tape-and-reel specifications. Ensure the component meets RoHS3 compliance requirements for your target market. Cross-reference the DigiKey part number 497-4682-2-ND for accurate distributor identification and lead time verification before procurement.

Selection Notes

Select this component when a low-power TRIAC with logic-compatible gate drive is required for 600 V AC loads. The 1 A RMS rating suits small appliances and lighting controls. Verify that the 3 mA gate trigger current matches the output capability of the driving circuitry. Consider the TO-92-3 package constraints for thermal dissipation in enclosed designs.

Part Context

This device belongs to the Z01 series of single TRIACs from STMicroelectronics. The series offers various voltage ratings and current capacities in compact packages. The Z0103 variant specifically targets low-current applications requiring high sensitivity. The 'N' designation typically indicates a specific pinout or manufacturing lot code within the family.

Replacement Considerations

Direct substitutes include other 1 A, 600 V logic TRIACs in TO-92 packages such as the BT136 series if higher current is acceptable, or the BTA16 series for increased capacity. Verify gate sensitivity and holding current compatibility when replacing with devices from Littelfuse or WeEn Semiconductors.

FAQ

What is the maximum gate trigger current for the Z0103NA 5AL2?

The maximum gate trigger current (Igt) is specified as 3 mA.

Is the Z0103NA 5AL2 suitable for high-frequency switching?

The device is designed for line frequency applications (50/60 Hz). Its non-repetitive surge ratings are defined at these frequencies, indicating it is not intended for high-frequency PWM switching without careful derating.

What package type does the Z0103NA 5AL2 use?

It uses a TO-92-3 package, also referred to as TO-226AA, with formed leads for through-hole mounting.
