Overview
The Z0103MA,116 is a planar passivated four-quadrant triac manufactured by WeEn Semiconductors. It features a very sensitive gate structure designed for direct interfacing with logic-level integrated circuits and low-power gate drivers. The device is housed in a SOT-223 (SC-73) surface-mountable plastic package. Key electrical parameters include a rated repetitive off-state voltage of 400 V, an on-state RMS current of 1 A, and a non-repetitive peak on-state current of 8.5 A. The maximum operating junction temperature is specified at +125 °C.
Feature Summary
- Planar passivated construction ensures robust performance and reliability.
- Very sensitive gate architecture enables efficient triggering from low-power sources.
- Four-quadrant operation allows compatibility with various gate drive polarities.
Applications
- Direct interfacing to logic level ICs
- Low power gate driver applications
- General purpose AC switching
Procurement Notes
Verify the specific ordering suffix against manufacturer documentation to confirm exact packaging and tape-and-reel specifications. Confirm RoHS compliance status and lead-free conversion dates via official datasheets before procurement. Ensure the selected variant matches the required voltage rating and package type for the target design.
Selection Notes
Select this component when a surface-mount triac with high gate sensitivity is required for space-constrained designs. The SOT-223 package offers a compact footprint suitable for automated assembly. Verify that the 400 V blocking voltage meets the circuit's peak inverse voltage requirements and that the 1 A RMS current capacity aligns with the load specifications.
Part Context
This part belongs to the Z0103 series of triacs from WeEn Semiconductors, which are characterized by their planar passivation technology and very sensitive gate characteristics. The series is engineered for modern electronics requiring reliable AC control with minimal gate drive power. The Z0103MA variant specifically denotes the 400 V rating within this family.
Replacement Considerations
Compatible substitutes include the Z0103MN,135 (600 V rating) and Z0103NN,135 (800 V rating), provided the higher voltage ratings do not conflict with design constraints. These alternatives share the same SOT-223 package and general functional characteristics but differ in their maximum off-state voltage capabilities.
