The 20CTQ035SPBF is a dual common cathode Schottky Rectifier manufactured by Vishay. This device is designed for high-frequency switching power supplies, converters, freewheeling diodes, and polarity protection applications. Its key feature is its low forward voltage drop, which minimizes power loss and improves efficiency. The 'SPBF' suffix indicates that this rectifier is compliant with RoHS standards, meaning it's lead-free.

Applications:

• High-frequency switching power supplies
• DC-DC converters
• Freewheeling diodes in inductive loads
• Polarity protection circuits

Features:

• Low forward voltage drop (VF)
• High surge current capability
• High-frequency operation
• Guard ring for enhanced ruggedness and long-term reliability
• RoHS compliant (lead-free)

Benefits:

• Increased efficiency in power conversion circuits due to low VF
• Reliable performance under high surge conditions
• Suitable for high-frequency applications due to fast switching speed
• Environmentally friendly due to RoHS compliance
• Enhanced reliability and robustness in demanding applications.

Specifications:

The 20CTQ035SPBF has a maximum repetitive peak reverse voltage of 35V. Its maximum average forward current is 20A (10A per diode). The maximum peak surge current is 700A. The operating junction temperature range is -40°C to +150°C. The forward voltage at 10A and 125°C is typically 0.49V.
