Product details

SOT-223 logic-level TRIAC for low-power AC switching

The Z0103MN 6AA4 is a logic-level sensitive-gate TRIAC from STMicroelectronics, rated for 600 V off-state voltage and 1 A RMS on-state current in a compact SOT-223 surface-mount package.

600 V blocking and 8 A surge capability

The 600 V off-state rating provides comfortable margin for 230 VAC or 277 VAC line switching, absorbing typical mains transients without avalanche failure. Non-repetitive surge current is rated at 8 A for 50 Hz and 8.5 A for 60 Hz — this handles the inrush from capacitive loads, incandescent lamps, or small motor starts without exceeding the device's peak current capability. Maximum hold current is 7 mA, ensuring the TRIAC latches on once triggered and commutates off cleanly when the load current drops below this threshold near the AC zero-crossing.

Frequently asked questions

What is the closest functional alternative to Z0103MN 6AA4?

The Z0103NN5AA4 is a close peer — same 1 A RMS rating and logic-level sensitive gate, but with an 800 V off-state voltage instead of 600 V. The SOT-223 package and pinout are identical, so it drops into the same PCB footprint without rewiring if higher voltage margin is needed.

What compliance documentation does STMicroelectronics provide for Z0103MN 6AA4?

The part is ROHS3 compliant per STMicroelectronics. Standard documentation includes the datasheet and RoHS declaration of compliance.
