Z0103NA0,412

Overview

The Z0103NA0,412 is a four-quadrant logic level TRIAC manufactured by WeEn Semiconductors. It features an 800 V repetitive peak off-state voltage and a 1 A RMS on-state current capability. The device utilizes a planar passivated structure with a very sensitive gate design, enabling direct interfacing to logic-level integrated circuits and low-power gate drivers. It is housed in a TO-92 plastic package, suitable for through-hole mounting applications requiring robust AC switching performance.

Feature Summary

• Four-quadrant logic level triggering for versatile gate drive compatibility
• Planar passivated construction ensuring high reliability and stability
• Very sensitive gate architecture allowing direct interface with logic ICs

Applications

• Direct interfacing to logic level integrated circuits
• Low power gate driver applications
• AC load switching in consumer electronics

Procurement Notes

Verify the specific ordering suffix and manufacturer designation when sourcing, as the part number appears across multiple distributors under both NXP and WeEn Semiconductors branding. Confirm the package type matches the required TO-92 configuration and ensure the datasheet corresponds to the four-quadrant logic level TRIAC specifications rather than other component types sharing similar alphanumeric codes.

Selection Notes

Select this component when an application requires a compact TRIAC capable of being driven directly by standard logic outputs without additional buffer circuitry. The 800 V rating provides sufficient margin for general mains-connected loads, while the 1 A current limit defines its suitability for small appliances and lighting control systems where space constraints favor the TO-92 form factor.

Part Context

This device belongs to the family of four-quadrant TRIACs designed for logic-level operation. It shares functional similarities with other sensitive gate TRIACs but is distinguished by its specific voltage and current ratings combined with the TO-92 packaging. The part is commonly associated with manufacturers like WeEn Semiconductors and NXP, reflecting industry consolidation in the discrete semiconductor sector.

Replacement Considerations

Potential substitutes include other four-quardrant logic level TRIACs with comparable 800 V and 1 A ratings in TO-92 packages. Verify gate trigger current specifications to ensure compatibility with existing logic drive levels before substituting.
