The Z0109MA 2AL2 is a standard triac from the Z01 series, designed for general-purpose AC switching applications. It features a sensitive gate configuration and is housed in a TO-92 package with three pins. The device supports an on-state RMS current of 1 A and withstands a peak non-repetitive surge current of 8.5 A. It operates at a maximum temperature of 125 °C and has a holding current maximum of 10 mA.
Verify the specific ordering suffix to ensure correct packaging and tape-and-reel specifications. Confirm that the sensitive gate variant aligns with the driver circuit requirements. Check for any recent product change notifications regarding manufacturing updates or material declarations before finalizing procurement orders.
Select this component for low-power AC load control where compact sizing is required. Ensure the driving circuit can provide sufficient gate current to trigger the sensitive gate reliably. Verify thermal management capabilities to maintain junction temperatures within the specified maximum operating limit during continuous operation.
This part belongs to the Z01 series of standard triacs manufactured by STMicroelectronics. The series is engineered for cost-effective AC power control solutions. The Z0109MA variant specifically addresses applications requiring moderate current handling with a small form factor, fitting into broader industrial and consumer electronics designs.
Consult official substitution lists for compatible triacs with matching current ratings and package types. Verify electrical characteristics such as holding current and gate trigger voltage to ensure functional equivalence in existing circuit designs without modification.
The gate trigger voltage is specified at 1.3 V.
The datasheet indicates suitability for general-purpose AC switching rather than high-frequency operations.
