Z0409NF 1AA2

Overview

The Z0409NF 1AA2 is a Triac manufactured by STMicroelectronics, designed for AC switching applications. It features a rated average on-state current of 4 A and supports a repetitive peak off-state voltage of 600 V. The device utilizes a TO-202 through-hole package with three pins. Key electrical parameters include a maximum holding current of 10 mA, a gate trigger voltage of 1.3 V, and a gate trigger current of 10 mA. It operates within a junction temperature range of -40 °C to +125 °C and has a peak on-state voltage of 2 V.

Feature Summary

Four-quadrant triggering capability for reliable gate control across all voltage polarities.

Applications

Lighting dimmers
Motor speed controls

Procurement Notes

Verify the exact part number against official STMicroelectronics documentation before procurement. Confirm that the suffix '1AA2' corresponds to the specific packaging and marking requirements for your assembly process. Ensure compatibility with the intended thermal management solution given the TO-202 package constraints.

Selection Notes

Select this component when a 4 A AC switch with 600 V blocking capability is required in a through-hole configuration. Compare the 10 mA gate trigger current against driver capabilities to ensure sufficient drive strength. Consider the TO-202 package size relative to available PCB space and mounting hardware requirements.

Part Context

This Triac belongs to the Z04xxMF/NF series from STMicroelectronics, which provides robust solutions for general-purpose AC power control. The series is characterized by high surge current handling and standardized pinouts, facilitating design reuse across various appliance and industrial control platforms requiring moderate current switching.

Replacement Considerations

Direct replacements may include other 4 A, 600 V Triacs in TO-202 packages from manufacturers such as Littelfuse or Vishay, provided gate trigger characteristics and thermal ratings are compatible. Verify pinout compatibility to avoid circuit redesign.
