DB3TG-AP

Overview

The DB3TG-AP is a bidirectional trigger diode manufactured by Micro Commercial Components. It belongs to the Diac product category within the thyristor sub-classification. The device is designed for operation across a wide temperature range, supporting minimum working temperatures of -40°C and maximum working temperatures of +125°C. The component utilizes a plastic package configuration compliant with RoHS standards.

Feature Summary

• Bidirectional triggering capability for symmetric conduction characteristics
• Wide operational temperature tolerance suitable for demanding environments
• Glass passivated junction construction for enhanced reliability

Applications

• Triggering circuits for silicon-controlled rectifiers (SCRs)
• Gate drive applications for triacs in AC power control systems
• Lighting dimmer switch implementations
• Motor speed control circuitry

Procurement Notes

Verify the specific datasheet version provided by Micro Commercial Components to confirm exact breakdown voltage tolerances and current ratings before integration. Ensure that the selected package variant matches the PCB footprint requirements. Cross-reference the manufacturer part number with authorized distributors to confirm current availability status and compliance documentation.

Selection Notes

Select this component when a bidirectional trigger device is required for AC phase control applications. Consider the -40°C to +125°C operating range for environmental suitability. Compare peak holding current and breakover voltage specifications against the target load requirements to ensure reliable triggering performance without false activation.

Part Context

This component is part of the Micro Commercial Components discrete semiconductor portfolio, specifically categorized under thyristors and diacs. It serves as a specialized trigger element distinct from standard rectifier or Zener diodes within the MCC lineup. The AP suffix typically denotes a specific packaging or compliance variant within the manufacturer's standard catalog structure.

Replacement Considerations

Consult official replacement guides for equivalent bidirectional trigger diodes from other manufacturers. Verify pinout compatibility and electrical parameter alignment, particularly breakover voltage and peak current handling, before substituting with generic equivalents.
