Overview
The Littelfuse 2N6349AG is a surface mount thyristor designed for full-wave AC control applications. It features an 800 V peak repetitive off-state voltage and a 12 A on-state RMS current rating at a case temperature of +80°C. The device utilizes diffused and glass-passivated junctions to ensure parameter uniformity and stability. It operates within a junction temperature range of -40°C to +125°C and includes gate triggering guaranteed in all four quadrants.
Feature Summary
- Thermowatt construction provides low thermal resistance, high heat dissipation, and durability.
- All diffused and glass-passivated junctions enhance parameter uniformity and long-term stability.
- Gate triggering is guaranteed across all four operating quadrants for versatile control.
Applications
- Light dimmers
- Motor controls
- Heating controls
- Power supplies
Procurement Notes
Verify the specific part number against official Littelfuse documentation to confirm the Pb-free package designation and JEDEC registered data points. Ensure that the selected component meets the required thermal management specifications for the intended application environment.
Selection Notes
Select this component when an 800 V blocking voltage and 12 A RMS current capacity are required in a TO-220AB surface mount package. Consider the thermal derating curves for operation above +80°C case temperature and verify gate trigger requirements across all four quadrants for the specific circuit design.
Part Context
This device belongs to the 2N634xA series of surface mount thyristors from Littelfuse. The series includes variants with different blocking voltages, such as the 2N6344A and 2N6348A rated at 600 V, while the 2N6349A offers an 800 V rating. All devices share similar current ratings and package styles.
Replacement Considerations
Compatible substitutes include other 800 V, 12 A surface mount thyristors in the TO-220AB package. Verify equivalent electrical characteristics, particularly peak repetitive off-state voltage, on-state RMS current, and gate trigger parameters, before implementation.
FAQ
