Z0103MA,126

Overview

The Z0103MA,126 is a bidirectional triac from WeEn Semiconductors housed in a TO-92-3 package. It features an RMS on-state current of 1 A and a non-repetitive peak on-state current of 8.5 A. The device supports rated repetitive peak off-state voltages of 400 V, 600 V, or 800 V. Key electrical characteristics include a maximum holding current of 50 mA and a gate trigger voltage up to 2.5 V. Operating temperatures range from -40°C to +125°C.

Feature Summary

• Bidirectional switching capability for AC load control applications
• Robust non-repetitive surge current handling capacity
• High thermal stability with extended operating temperature range

Applications

• Lighting dimmer circuits
• Motor speed control systems
• Solid state relays

Procurement Notes

Verify the specific voltage grade suffix (e.g., 400V, 600V, 800V) as the base part number may cover multiple ratings. Confirm the tape-and-reel quantity associated with the .126 suffix matches project requirements. Ensure compatibility with TO-92-3 mounting constraints during integration.

Selection Notes

Select this component when a compact TO-92-3 form factor is required for low-power AC switching. Evaluate the specific voltage rating needed for the application against the available variants within the Z01 series. Consider the gate sensitivity and holding current specifications for reliable triggering in the target circuit design.

Part Context

This device belongs to the Z01 series of bidirectional triacs manufactured by WeEn Semiconductors. The series is designed for general-purpose AC power control. The TO-92-3 package provides a cost-effective solution for through-hole assembly in consumer electronics and industrial control modules requiring moderate current handling.

Replacement Considerations

Cross-reference with other manufacturers' TO-92-3 triacs offering identical 1A RMS current and compatible voltage ratings. Verify pinout compatibility and thermal resistance values before substitution.
