Product details

Logic-level gate trigger — why it matters for the drive circuit

The Z0103NA 2AL2 is a logic-level sensitive-gate triac with a maximum gate trigger current of 3 mA and a maximum gate trigger voltage of 1.3 V.

800 V off-state and 1 A RMS — load and transient headroom

Rated for 800 V off-state voltage, this triac handles 240 VAC mains with a healthy transient margin — useful for appliance motor-speed controls, lighting dimmers, and heater regulators where line surges can exceed 600 V. The 1 A RMS on-state current ceiling suits loads up to roughly 100 W at 120 VAC or 200 W at 240 VAC, covering small universal motors, solenoid valves, and resistive heaters. Non-repetitive surge current is rated at 8 A (50 Hz) and 8.5 A (60 Hz), giving the device enough ruggedness to survive inrush from incandescent lamps or capacitor-charging loads without external snubber protection in many cases.

Industrial temperature range and through-hole package

The TO-92-3 through-hole package (TO-226AA with formed leads) is a standard three-lead footprint that hand-solders easily and suits low-volume production or prototyping.

ROHS3 compliance is confirmed, and the part is available in Cut Tape (CT) and Tape & Box (TB) packaging for through-hole assembly lines.

Frequently asked questions

Does Z0103NA 2AL2 have a sensitive gate?

Yes, the Z0103NA 2AL2 is a logic-level sensitive-gate triac. Its maximum gate trigger current is 3 mA and maximum gate trigger voltage is 1.3 V, allowing direct drive from a microcontroller I/O pin or logic gate without an intermediate driver.

What is the gate trigger current of Z0103NA 2AL2?

The maximum gate trigger current (Igt) is 3 mA. The maximum gate trigger voltage (Vgt) is 1.3 V. These low thresholds classify it as a sensitive-gate triac, suitable for logic-level triggering.
