Overview
The Z0103NN,135 is a planar passivated 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 operates with a maximum junction temperature of +125 °C and includes a high dV/dt rating of 10 V/µs for noise immunity. Packaged in a surface-mount SOT-223 (SC-73) plastic housing, it is designed for direct interfacing with logic-level integrated circuits and low-power gate drivers.
Feature Summary
- Four-quadrant logic level triggering for simplified gate drive requirements
- Planar passivated construction for enhanced reliability
- High commutation rate capability via elevated dV/dt rating
Applications
- Direct interfacing to logic level ICs
- Low power gate driver circuits
- General purpose AC switching applications
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and tape-and-reel specifications. Ensure that the requested part number matches the exact electrical ratings and thermal characteristics required for the target application environment before finalizing procurement orders.
Selection Notes
Select this component when an 800 V blocking voltage and 1 A continuous current are sufficient for the load. The SOT-223 package is suitable for surface-mount assembly processes. Confirm that the gate trigger current limits align with the output capabilities of the driving microcontroller or logic circuit.
Part Context
This triac belongs to the Z0103 series of four-quadrant logic level devices from WeEn Semiconductors. The series is characterized by high sensitivity gates and robust planar passivation technology. These components are engineered to replace through-hole equivalents in modern compact surface-mount designs while maintaining reliable AC control performance.
Replacement Considerations
Cross-reference with other Z0103 variants such as Z0103MN0,135 for different voltage ratings. Verify pinout compatibility and thermal resistance differences when substituting with similar SOT-223 triacs from other manufacturers.
