KA5L0380R, Fairchild Power Switch 800V, 3A, TO-220F

The KA5L0380R is an advanced off-line SMPS power switch integrating a high-voltage SenseFET and a current-mode PWM controller. Designed to optimize efficiency and simplify design, it includes key protections such as over-current, over-voltage, and thermal shutdown. The built-in auto-restart function provides safe operation, making it ideal for power adapters, VCRs, and printers.

Key Features :

• High Voltage Capability: 800V maximum drain voltage, ideal for off-line SMPS applications.
• Current Handling: Supports up to 3A continuous current, with a pulsed current capacity of 12A.
• Integrated Protection: Built-in protections including over-current, over-voltage, and thermal shutdown.
• Efficient Design: Integrated high-voltage SenseFET and PWM controller for optimized performance.
• Auto-Restart Function: Automatically restarts after fault conditions for safer operation.
• Reliable Thermal Performance: Available in TO-220F package for enhanced heat dissipation in high-power environments.
