Overview
The Littelfuse 2N6348AG is a surface-mount silicon gate controlled thyristor (Triac) designed for full-wave AC control applications. It features a peak repetitive off-state voltage of 600 V and an on-state RMS current rating of 12 A at a case temperature of +80°C, derating to 6.0 A at +90°C. The device supports a peak non-repetitive surge current of 100 A with an I²t value of 59 A²s. Electrical characteristics include a typical gate trigger current of 6.0 mA in Quadrant I and a holding current of 6.0 mA at 25°C. The component operates within a junction temperature range of -40°C to +125°C and utilizes a TO-220AB package.
Feature Summary
- All diffused and glass passivated junctions ensure parameter uniformity and stability.
- Thermowatt construction provides low thermal resistance and high heat dissipation capabilities.
- Gate triggering is guaranteed across all four operating quadrants.
Applications
- Light dimmers
- Motor controls
- Heating controls
- Power supplies
Procurement Notes
Verify the specific ordering suffix 'G' corresponds to the lead-free package configuration as documented in the manufacturer's datasheet. Confirm that the TO-220AB physical dimensions and pin assignments align with the target PCB layout requirements before finalizing procurement specifications.
Selection Notes
Select this component for applications requiring robust full-wave AC switching with a 600 V blocking capability. Ensure the thermal management design maintains the case temperature below +80°C to utilize the full 12 A RMS current rating, or apply appropriate derating curves if higher case temperatures are anticipated during operation.
Part Context
This part belongs to the 2N634xA series of surface-mount thyristors manufactured by Littelfuse. The series includes variants with different voltage ratings, such as the 2N6344A and 2N6349A, which share similar current capacities and package styles but differ in their maximum off-state voltage specifications.
Replacement Considerations
Direct substitutes within the same family include the 2N6344A and 2N6349A, provided the system voltage requirements match the respective 600 V or 800 V ratings of those specific models.
FAQ
