Z0109NN0,135

Overview

The Z0109NN0,135 is a planar passivated sensitive gate four-quadrant triac manufactured by WeEn Semiconductors. It is housed in a SOT-223 (SC-73) surface-mountable plastic package designed for enhanced noise immunity and direct interfacing with logic-level ICs. Key electrical parameters include a repetitive peak off-state voltage (VDRM) of 800 V and an RMS on-state current (IT(RMS)) of 1 A. The device supports a non-repetitive peak on-state current (ITSM) of 13.8 A. Gate triggering characteristics specify a maximum gate trigger voltage (VGT) of 1 V and a maximum gate trigger current (IGT) of 10 mA across all quadrants. The on-state voltage is 1.3 V, with a holding current (Ih) maximum of 10 mA. Leakage current at VDRM is limited to 500 uA. The component operates within a junction temperature range up to +125 °C.

Selection Notes

Select this component when designing circuits requiring robust noise immunity and direct logic interface without additional buffer stages. The 800 V blocking voltage suits general AC line applications, while the 1 A RMS rating defines the continuous load capacity. Ensure the PCB layout accommodates the SOT-223 thermal dissipation requirements for sustained operation near the maximum junction temperature limit.

Part Context

This part belongs to the Z0109 series of sensitive gate triacs from WeEn Semiconductors. It shares the SOT-223 form factor with variants like Z0107NN0 and Z0109MN but differs in specific gate sensitivity and surge current ratings. The series is engineered for compact surface-mount designs where space constraints and reliable triggering from weak logic signals are critical design factors.

Replacement Considerations

Cross-reference with Z0107NN0 for similar voltage and current ratings but verify gate trigger current differences. Check Z0109MN for package compatibility, noting its lower 600 V rating makes it unsuitable for 800 V applications.
