Overview
The Z0109NN,135 is a sensitive gate four-quadrant triac manufactured by WeEn Semiconductors. It features an RMS on-state current of 1 A and a repetitive peak off-state voltage of 800 V. The device has a non-repetitive peak on-state current of 8.5 A and a maximum holding current of 10 mA. Gate triggering requires a voltage of 1 V and a current of 10 mA. The on-state voltage is 1.3 V, with a leakage current of 500 uA at VDRM. It operates within a temperature range up to +125 C and is housed in a SOT-223-4 surface-mount package.
Feature Summary
- Direct interfacing capability with logic level ICs
- Enhanced noise immunity for reliable operation
- Planar passivated construction for voltage ruggedness
Applications
- General purpose low power motor control
- Home appliances
- Industrial process control
- Low power AC fan controllers
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official documentation to confirm packaging details such as reel or cut tape specifications. Ensure compliance with RoHS and REACH requirements by checking the latest product data sheet. Confirm that the component matches the required SOT-223-4 footprint for PCB integration. Validate the thermal characteristics against the intended application environment.
Selection Notes
Select this component when a surface-mount triac with high blocking voltage and sensitive gate drive is required. The 800 V rating suits general AC switching applications. The 1 A RMS current capacity defines its power handling limits. Consider the SOT-223-4 package size for space-constrained designs. Verify gate trigger parameters match the driving circuit capabilities.
Part Context
This part belongs to the Z0109 series of sensitive gate triacs from WeEn Semiconductors. The series is designed for applications requiring enhanced noise immunity and direct logic interface. The Z0109NN variant specifically denotes the sensitive gate configuration in a surface-mountable plastic package. It is part of the broader thyristor family used for AC power control.
Replacement Considerations
Check for compatible substitutes within the same series or equivalent packages from other manufacturers. Ensure electrical parameters like VDRM and IT(RMS) meet or exceed original requirements. Verify pinout compatibility for SOT-223-4 packages. Consult official substitution guides for validated alternatives.
