Product details

Sensitive gate triac for low-power logic drive

The STMicroelectronics Z0103MA 1AA2 is a logic-sensitive gate triac rated for 600 V off-state voltage and 1 A RMS on-state current, housed in a TO-92-3 through-hole package.

The 600 V off-state voltage covers mains with margin for line transients. The 1 A RMS on-state current suits small resistive loads. The 7 mA maximum holding current ensures the triac latches on once triggered.

Through-hole TO-92-3 and temperature range

The TO-92-3 package is a standard three-lead through-hole format, easily soldered into perfboard or PCB.

Frequently asked questions

What is the difference between Z0103MA and Z0107MA?

The Z0107MA is a higher-current variant in the same family, typically rated at 1 A RMS as well but with a higher surge capability. The Z0103MA 1AA2 has a gate trigger current of 3 mA max and a non-repetitive surge rating of 8 A / 8.5 A at 50/60 Hz. The Z0107MA would have a higher surge rating; check the specific datasheet for exact values.

Is Z0103MA a sensitive gate triac?

Yes. The Z0103MA 1AA2 is classified as a Logic - Sensitive Gate triac, meaning its gate trigger current is low enough (3 mA max) to be driven directly from logic-level signals without an external driver.
