1 A sensitive-gate TRIAC for low-power AC switching
The STMicroelectronics Z0107NA 5AL2 is a logic-sensitive gate TRIAC rated for 800 V off-state voltage and 1 A RMS on-state current, housed in a through-hole TO-92 package. Its sensitive gate (5 mA max trigger current, 1.3 V max trigger voltage) allows direct drive from a microcontroller GPIO, a logic gate, or a low-power transistor without an intermediate driver stage — a common requirement in appliance control boards, solid-state relay inputs, and small motor or valve actuators.
Ratings that define the load and the drive
Gate trigger current of 5 mA max and trigger voltage of 1.3 V max confirm compatibility with 5 V logic families. The holding current of 10 mA max means the TRIAC will latch on once triggered and will drop out when the load current falls below that threshold.
The base product number is Z0107, which covers multiple trigger-current and package variants; the full order code Z0107NA 5AL2 specifies the TO-92 through-hole package with the 5 mA sensitive gate option.
