The RURD860S is an ultrafast rectifier diode manufactured by Intersil. It's designed for applications that demand fast and efficient switching, making it suitable for various power electronics designs. A key advantage of this diode is its combination of low forward voltage drop and ultrafast reverse recovery time, both of which contribute to reduced power losses and enhanced system efficiency.

Applications

• Switch Mode Power Supplies (SMPS)
• Power Factor Correction (PFC) circuits
• Uninterruptible Power Supplies (UPS)
• High-frequency inverters
• Freewheeling diodes in motor control

Features

• Ultrafast recovery time (typically around 35ns)
• Low forward voltage drop (typically 1.5V at 8A)
• High reverse voltage capability (600V)
• Low leakage current
• High surge current capability (80A)
• Operating junction temperature: -65°C to +175°C

Benefits

• Reduced switching losses, leading to improved energy efficiency.
• Lower heat dissipation, enhancing the reliability and lifespan of the system.
• Improved performance in high-frequency switching applications.
• Simplified circuit design due to predictable and fast switching characteristics.
• Minimized EMI (Electromagnetic Interference) due to reduced reverse recovery current.

Additional Details

The RURD860S is typically housed in a TO-220AC package, which provides effective heat dissipation and ease of mounting. Adequate heat sinking is crucial, especially when operating at higher current levels, to ensure optimal performance and prevent overheating. The ultrafast recovery characteristics of the RURD860S make it well-suited for designs where minimizing reverse recovery current and associated noise is paramount.
