Overview
The AC03DGM(19)-AZ is a three-terminal bidirectional triac manufactured by Renesas Electronics Corporation. It belongs to the AC03 series of molded TRIACs, designed for general-purpose switching applications. The device features a robust plastic encapsulation suitable for surface mounting or through-hole integration depending on the specific lead frame configuration associated with the (19) suffix. As a thyristor-based component, it provides reliable control of AC loads in electronic circuits.
Feature Summary
- Bidirectional conduction capability for AC load control
- Molded plastic package construction for environmental protection
- Sensitive gate trigger characteristics for low power drive compatibility
Applications
- Solid state relay output stages
- Lighting dimmer circuitry
- Motor speed control systems
Procurement Notes
Verify the exact datasheet revision and mechanical dimensions corresponding to the (19) suffix, as packaging variations exist within the AC03 family. Confirm RoHS compliance status directly with the manufacturer, as older NEC-derived part numbers may have varying regulatory histories. Ensure the supply source is an authorized distributor to guarantee authenticity.
Selection Notes
Select this component when a 3A rated bidirectional switch is required for AC power management. Compare thermal resistance values against the intended heat sink or PCB copper area requirements. Verify that the gate trigger current specifications align with the driving microcontroller or logic interface voltage levels to ensure reliable turn-on.
Part Context
This part is part of the legacy NEC Electronics triac portfolio acquired by Renesas Technology Corporation. The AC03 series represents a range of molded TRIACs with varying current ratings. The AC03DGM variant specifically denotes the 3 Ampere rating within this molded line, often used in consumer electronics and industrial control panels.
Replacement Considerations
Direct pin-to-pin replacements include the AC03DJM and AC03FGM variants from the same manufacturer family. Cross-brand equivalents such as the T3A6CI from KEC may be considered if electrical parameters match the specific application requirements.
