Overview
The Littelfuse Inc. 2N6073AG is a sensitive gate TRIAC designed for full-wave AC control applications. It features a peak repetitive off-state voltage of 400V and an on-state RMS current rating of 4A. The device utilizes a TO-225AA through-hole package with three pins. Key electrical parameters include a maximum holding current of 15 mA, a gate trigger voltage of 2.5 V, and a gate trigger current of 10 mA. The on-state voltage is specified at 2 V, while the peak non-repetitive surge current capability reaches 30 A. The component supports a maximum operating temperature of 110°C.
Feature Summary
- Sensitive gate logic design for efficient triggering
- Through-hole TO-225AA package construction
- Optimized for full-wave AC power control
Applications
- Light dimmers
- Motor controls
- Heating controls
- Power supplies
Procurement Notes
Verify the specific Littelfuse datasheet to confirm exact pinout configurations and thermal characteristics before integration. Ensure that the selected circuit design accommodates the 400V blocking voltage and 4A continuous current limits. Confirm that the gate trigger requirements align with the driving logic levels to ensure reliable switching performance under all expected operating conditions.
Selection Notes
Select this component when a low-power TRIAC is required for AC load switching in consumer or industrial equipment. The sensitive gate characteristic simplifies drive circuitry compared to standard gate devices. Consider the TO-225AA form factor for board space constraints and verify that the 110°C junction temperature rating meets the ambient thermal environment of the final assembly without excessive heatsinking.
Part Context
This part belongs to the Low Power TRIAC series from Littelfuse, which covers ratings up to 1200V. The 2N6073AG specifically targets the lower voltage segment of this family, providing a robust solution for general-purpose AC control tasks where moderate current handling is sufficient.
Replacement Considerations
Consult official Littelfuse cross-reference documentation for verified substitute part numbers. Do not assume functional equivalence based solely on similar voltage and current ratings without verifying gate sensitivity and package compatibility.
