Key Features
- 1A RMS on-state current with 700V voltage rating for compact AC switching applications
- Low gate trigger current of 5 mA enabling direct microcontroller or optocoupler drive without additional buffer stages
- SOT-223 surface-mount package with exposed thermal pad for improved heat dissipation on PCB
- Quadrant I and III triggering capability allowing flexible gate drive from both positive and negative signals
- Snubberless design option supporting simplified circuit layouts by eliminating RC snubber components
Applications
The Z0107NA TRIAC is used in low-power AC switching applications such as small appliance controls, lamp dimmers, and fan speed regulators where load currents stay below 1A RMS. Its low gate trigger current makes it directly compatible with optocoupler outputs and logic-level gate drive circuits, simplifying isolation designs. The compact SOT-223 package suits space-constrained PCB assemblies in consumer electronics and HVAC control modules.

Frequently Asked Questions
What is the maximum blocking voltage and continuous current rating of the Z0107NA?
The Z0107NA is rated for 700V repetitive peak off-state voltage and 1A RMS on-state current. These ratings make it suitable for 120V or 230V AC mains applications where load power stays below approximately 230W, covering small motor loads, lamps, and heating elements.
How low is the gate trigger current of the Z0107NA, and can it be driven directly from an optocoupler?
The Z0107NA requires a gate trigger current of only 5 mA, which falls within the output capability of standard MOC-series optocouplers. This allows direct opto-isolated gate drive without an intermediate transistor stage, reducing component count and PCB area in isolated AC switching designs.
Which package does the Z0107NA 5AL2 use, and what are the thermal advantages?
The Z0107NA 5AL2 is housed in a SOT-223 surface-mount package featuring an exposed metal tab for direct soldering to a PCB copper area. This thermal connection enables junction-to-board thermal resistance well below that of standard TO-92 packages, supporting higher ambient operating temperatures without external heatsinks.
For a 230V AC fan speed controller, is the Z0107NA sufficient for a 100W motor load?
A 100W fan load at 230V draws approximately 0.43A RMS, which is well within the Z0107NA's 1A RMS rating with a comfortable 2x derating margin. The 700V blocking voltage also provides adequate headroom above the 325V peak of a 230V supply, making the Z0107NA suitable for this application.
What distinguishes the Z0107NA from the Z0110NA in terms of current handling?
The Z0107NA is rated at 1A RMS while the Z0110NA handles 1A with a slightly different gate sensitivity profile. For loads requiring currents between 1A and 4A, STMicroelectronics offers the Z0109 and Z0140 series TRIACs, all sharing compatible SOT-223 or TO-92 footprints for straightforward current rating upgrades.
