Z0107MA 1AA2

Overview

The Z0107MA 1AA2 is a three-terminal triac manufactured by STMicroelectronics, designed for AC power control applications. It features a sensitive gate configuration with a maximum gate trigger current of 5 mA and a gate trigger voltage of 1.5 V. The device supports a repetitive peak off-state voltage of 600 V and an RMS on-state current of 800 mA. It is housed in a TO-92 package with three pins. Key electrical parameters include a non-repetitive peak surge current of 8 A at 50 Hz, a maximum holding current of 10 mA, and a platinum group metal gate peak power rating of 1 W. The component operates within a junction temperature range up to 125°C.

Feature Summary

• Sensitive gate architecture enabling direct interface with logic circuits via low gate trigger requirements.
• Robust thermal management capability supported by a platinum group metal gate structure for high peak power handling.
• Standard through-hole TO-92 packaging facilitating easy integration into conventional printed circuit board layouts.

Applications

• Lighting dimmer circuits for residential and commercial illumination systems.
• Solid-state relay modules requiring isolated AC load switching.
• Temperature control regulators for heating elements in household appliances.

Procurement Notes

Verify the specific ordering suffix '1AA2' against the manufacturer's latest datasheet to confirm pinout orientation and marking codes. Ensure that the procurement channel provides original components with traceable documentation to avoid counterfeit devices. Cross-reference the RoHS compliance status with current environmental regulations applicable to your region before finalizing orders.

Selection Notes

Select this component when a sensitive gate triac is required for low-power triggering applications. The 600 V blocking voltage suits standard single-phase AC mains operations. Consider the TO-92 package constraints regarding thermal dissipation and physical space. Compare the 800 mA RMS current rating against the maximum load current to ensure adequate safety margins under continuous operating conditions.

Part Context

This part belongs to the Z0107 family of sensitive gate triacs from STMicroelectronics. The family is characterized by low gate current requirements suitable for microcontroller interfaces. Variants within the series may differ in voltage ratings or package types, but share the core sensitive gate technology. This specific model represents the standard through-hole version optimized for general-purpose AC switching tasks.

Replacement Considerations

The Z00607MA 1BA2 is listed as a similar alternative within the same product category. Verify compatibility by comparing the gate trigger characteristics and current ratings. Ensure that any substitute device matches the TO-92 footprint and maintains equivalent voltage blocking capabilities for safe replacement.
