Overview
The Z0103NN5AA4 is a planar passivated, very sensitive gate four-quadrant triac manufactured by STMicroelectronics. It is housed in a SOT-223 (SC-73) surface-mountable plastic package designed for direct interfacing with logic-level ICs and low-power gate drivers. The device features an RMS on-state current of 1 A and a rated repetitive peak off-state voltage of 800 V. Key electrical parameters include a maximum non-repetitive surge current of 8.5 A, a holding current of 7 mA, and a gate trigger current of 3 mA. It operates within a junction temperature range of -40°C to +125°C.
Feature Summary
- Very sensitive gate architecture enables direct interface with logic-level integrated circuits.
- Planar passivation technology ensures robust performance and reliability.
- Four-quadrant triggering capability allows operation across all gate polarities.
Applications
- Direct interfacing to logic level ICs
- Low power gate driver applications
- Industrial AC switching systems
Procurement Notes
Verify the specific suffix '5AA4' against the manufacturer's datasheet to confirm pinout and packaging details. Ensure compatibility with SOT-223 footprint requirements during PCB layout. Confirm RoHS compliance status through official documentation before integration into regulated assemblies.
Selection Notes
Select this component when a surface-mount triac with high sensitivity is required for logic-driven applications. The 800 V rating suits general AC control tasks. Verify that the 1 A RMS current meets load requirements and that the SOT-223 package fits the available board space constraints.
Part Context
This part belongs to the Z01 series of triacs from STMicroelectronics. The series is characterized by its use in applications requiring compact surface-mount solutions with reliable AC switching capabilities. The Z0103 variant specifically denotes the 800 V rating within this family.
Replacement Considerations
L0103NTRP by Littelfuse Inc. is listed as a parameter equivalent substitute. Verify electrical compatibility and package dimensions before substitution.
