Ultra-Fast / Super Fast Recovery Rectifiers Description
Ultra-Fast and Super-Fast Recovery Rectifiers are high-speed diodes designed for rapid switching and efficient rectification in modern power electronics. These rectifiers are ideal for use in high-frequency circuits, including SMPS (Switch Mode Power Supplies), inverters, and other fast-switching applications where low recovery time is crucial.
Main Features:
- Designed for surface-mounted applications
- Low-profile casing for space-saving PCB layouts
- Glass-passivated chip junction ensures long-term reliability and stability
- Easy assembly for automated mounting
- Lead-free and compliant with the EU Directive RoHS 2011/65/EU for environmentally friendly manufacturing
Ultra-Fast / Super-Fast Recovery Rectifier Applications
- Switch Mode Power Supplies (SMPS) - For efficient switching at high speeds with minimal power loss
- Inverters - Used in solar inverters, UPS, and motor drive systems
- High-frequency rectification - Ideal for circuits that require fast switching and low recovery time
