Overview
The Z0103MN,135 is a bidirectional triac manufactured by WeEn Semiconductors, designed for surface-mount applications in the SOT-223-4 package. It features a rated repetitive off-state voltage (VDRM) of 600 V and an RMS on-state current (It RMS) of 1 A. The device supports a non-repetitive peak on-state current of 8.5 A with a maximum on-state voltage of 1.3 V. Gate triggering requirements include a maximum gate trigger voltage (Vgt) of 1 V and a maximum gate trigger current (Igt) of 5 mA. The holding current (Ih) maximum is specified at 7 mA, while the off-state leakage current at VDRM is limited to 500 uA. The component operates within a maximum junction temperature of +125 C.
Feature Summary
- Four-quadrant logic level triac functionality for reliable gate triggering across all input polarities.
- Surface-mount construction utilizing the SOT-223-4 package for automated assembly integration.
- High thermal stability supporting operation up to a maximum junction temperature of +125 C.
Applications
- Lighting control systems requiring compact switching solutions
- Solid-state relay circuits for low-power load management
- Motor speed control applications for small AC loads

Selection Notes
Select this component when a 600 V blocking capability and 1 A continuous current rating are required in a surface-mount form factor. Ensure the driving circuit can supply at least 5 mA at 1 V to guarantee reliable turn-on under worst-case conditions. Verify that the PCB layout accommodates the SOT-223-4 footprint and provides adequate thermal relief for the expected power dissipation levels during conduction.
Part Context
This part belongs to the Z0103 series of logic level triacs from WeEn Semiconductors. The series typically includes variants with different voltage ratings and packaging options, such as through-hole TO-92 configurations. The MN designation specifically identifies the surface-mount variant, distinguishing it from other package types within the same electrical family.
Replacement Considerations
Direct replacements must match the 600 V rating, 1 A current capacity, and SOT-223-4 package. Cross-reference with other manufacturers' 600 V logic-level triacs in SMD packages, ensuring pinout compatibility and equivalent gate sensitivity specifications.
