VISHAY SF5408-TR Ultrafast Avalanche Diode, 1kV, 3A, 1.7V

The VISHAY SF5408-TR is an ultra-fast Avalanche Sinterglass Diode, engineered for demanding high-frequency and high-voltage applications. It features solderable axial leads compliant with the MIL-STD-750 standard, offering versatile mounting options in any position. This robust diode is housed in a hermetically sealed, glass-passivated axial-leaded glass envelope, ensuring exceptional reliability and protection against environmental factors.

Its design delivers outstanding electrical characteristics, including a high repetitive peak reverse voltage of 1kV and a low forward voltage of just 1.7V. With an ultra-fast reverse recovery time of 75 nanoseconds and a high forward surge current capability of 150A, it excels in circuits requiring rapid switching and high transient current handling.

Key Features & Applications

• Ultra-Fast Performance: A reverse recovery time of 75ns makes it ideal for high-frequency circuits.
• High Reliability: Glass-passivated junction and hermetically sealed construction ensure long-term stability.
• Robust Electrical Specs: Combines high reverse voltage (1kV) with a low reverse current for efficient operation.
• Easy Identification: A colour band clearly denotes the cathode end for correct circuit orientation.

This component is perfectly suited for critical roles in switched-mode power supplies (SMPS), high-frequency inverters, and other precision power management systems. Its qualifications make it a trusted choice for aerospace, defence, and military electronics where component reliability is non-negotiable.
