Overview
The Z0110DN 5AA4 is a bidirectional triac manufactured by STMicroelectronics, designed for surface-mount applications in the SOT-223 package. It features an RMS on-state current (It RMS) of 1 A and a non-repetitive peak on-state current of 8.5 A. The device supports a rated repetitive off-state voltage (VDRM) of 800 V with a maximum off-state leakage current of 5 uA at VDRM. Key electrical parameters include an on-state voltage of 1.6 V, a maximum holding current (Ih) of 10 mA, a gate trigger voltage (Vgt) of 1.3 V, and a gate trigger current (Igt) of 25 mA. The component operates within a temperature range of -40°C to +125°C.
Feature Summary
- Surface-mount construction in a compact SOT-223 package for automated assembly
- Bidirectional switching capability for AC load control applications
- High thermal stability supporting operation up to 125°C junction temperature
Applications
- Lighting dimmers and soft-start circuits
- Solid-state relays for AC loads
- Motor speed control systems
Procurement Notes
Verify the specific suffix '5AA4' against the manufacturer's latest datasheet to confirm pinout and marking consistency. Ensure the procurement channel provides traceable documentation confirming the component originates from authorized STMicroelectronics distribution channels to mitigate counterfeit risks.
Selection Notes
Select this component when a 1 A RMS current rating and 800 V blocking voltage are required in a surface-mount form factor. Compare the 25 mA gate trigger current requirement against available driver capabilities. Verify that the SOT-223 thermal dissipation characteristics meet the system's power handling requirements under expected operating conditions.
Part Context
This part belongs to the Z01 series of standard triacs from STMicroelectronics. The series is characterized by robust performance in general-purpose AC switching applications. The Z0110 variant specifically denotes the 1 A current class within this family, sharing common packaging and thermal profiles with other members like the Z0109.
Replacement Considerations
Potential substitutes include the Z0109NN 5AA4 or Z0109MN 5AA4. Verify compatibility regarding gate trigger current specifications and exact voltage ratings before substitution.
