Z0103NA,412

Overview

The Z0103NA,412 is a bidirectional triac manufactured by WeEn Semiconductors. It features a rated repetitive off-state voltage (VDRM) of 600 V and an on-state RMS current (IT(RMS)) of 1 A. The device has a non-repetitive peak on-state current of 13.8 A and a maximum on-state voltage of 1.3 V. Gate trigger voltage (VGT) is 1 V with a gate trigger current (IGT) of 5 mA. The holding current (Ih) maximum is 7 mA, and the off-state leakage current is 500 uA at VDRM. It operates within a temperature range up to +125 C and is housed in an SOT-223-4 surface-mount package.

Procurement Notes

Verify the specific suffix against official manufacturer documentation to confirm exact packaging configuration and reel specifications. Ensure the component matches the required voltage and current ratings for the target circuit design before procurement.

Selection Notes

Select this component based on its 600 V blocking voltage and 1 A continuous current rating. Confirm that the SOT-223-4 package footprint aligns with the PCB layout requirements and that the thermal management strategy supports the specified operating temperature range.

Part Context

This part belongs to the Z0103 series of triacs from WeEn Semiconductors. The series provides general-purpose AC switching solutions. The NA variant specifically denotes the 600 V rating and standard packaging configuration within this product line.

Replacement Considerations

Check for direct cross-reference parts with identical 600 V, 1 A specifications and SOT-223-4 packages. Verify pinout compatibility and electrical parameters such as gate trigger current before substitution.
