دايود TVS أحادي الاتجاه SA14A 14 فولت 22 أمبير

SA14A Unidirectional TVS Diode (14V / 22A)

The SA14A is a specialized Transient Voltage Suppression (TVS) diode housed in a DO-15 axial package, designed to safeguard sensitive electronic circuits from high-energy voltage transients. It is engineered to clamp sudden spikes—such as those induced by lightning, ESD events, or inductive switching—diverting excess energy away from critical components. With a 14V reverse standoff voltage and a rapid response time of less than 1.0 picosecond, it provides robust and predictable protection for modern communication and control systems.

Key Features

• 
  

  High Transient Protection: Capable of handling 500W of peak pulse power (10/1000 micro_s waveform) to absorb heavy electrical stress.

  
  


• 
  

  Ultra-Fast Response: Typically reacts in less than 1.0ps, ensuring protection begins before transients can damage downstream ICs.

  
  


• 
  

  Low Leakage Current: Features a minimal reverse leakage of 1 micro_A, ensuring negligible power drain during normal operation.

  
  


• 
  

  Durable Construction: Built with a glass-passivated junction in a DO-15 axial package for long-term reliability and thermal stability.

  
  


• 
  

  Wide Thermal Range: Designed to operate in extreme environments with a junction temperature range of −65°C to +175°C.
