Z0107NA0/L02EP

Overview

The Z0107NA0/L02EP is a planar passivated very sensitive gate four quadrant triac manufactured by WeEn Semiconductors. It is housed in a TO-92 plastic package and designed for applications requiring direct interfacing to logic level ICs and low power gate drivers. The device features an RMS on-state current of 1 A, a repetitive peak off-state voltage of 800 V, and a maximum junction temperature of 125 °C. Its gate trigger current is specified at 5 mA across quadrants Q1, Q2, and Q3, and 7 mA in Q4. The component exhibits a dV/dt rating of 20 V/µs and an on-state voltage characteristic typical for this class of thyristor.

Feature Summary

• Very sensitive gate structure enabling direct interface with logic level integrated circuits
• Planar passivated construction providing enhanced immunity to noise
• Four quadrant operation ensuring reliable triggering in all AC line polarities

Applications

• Lighting control systems
• Motor speed control circuits
• Heater control applications

Procurement Notes

Verify the specific suffix EP against official manufacturer documentation to confirm any unique packaging or material compliance variations. Ensure the ordering part number matches the exact requested configuration. Cross-reference the 12NC code for accurate supply chain identification. Confirm RoHS and lead-free status through the latest product change notifications provided by WeEn Semiconductors.

Selection Notes

Select this component when a robust triac with high noise immunity is required for logic-level driven applications. The 800 V blocking voltage suits general mains voltage operations. Verify that the 1 A RMS current rating meets the load requirements. Consider the thermal management needs given the 125 °C maximum junction temperature limit in the TO-92 package.

Part Context

This part belongs to the Z0107 family of triacs from WeEn Semiconductors. Variants within this series differ primarily by voltage ratings and package types, such as the SOT223 versions like Z0107NN. The NA0 designation typically indicates the standard voltage rating and through-hole packaging configuration suitable for general purpose switching tasks.

Replacement Considerations

Compatible substitutes include other 1 A, 800 V triacs in TO-92 packages with similar gate trigger characteristics. Verify pinout compatibility and thermal resistance values before substitution. Check datasheets for equivalent dV/dt ratings and holding currents to ensure circuit stability.
