SA58CAHE3/54 Circuit Protection

TVS - Diodes

SA58CAHE3/54 is a type of Transient Voltage Suppressor (TVS) diode which is primarily developed to protect electronic devices from damages caused by over voltage conditions. It is a two-terminal, semi-insulated device that can absorb and dissipate large amounts of electrical energy.

Application Field

SA58CAHE3/54 TVS diodes are used in a wide range of electronic devices such as computers, telecommunication systems, military-electronics, medical equipment, and automotive systems. They are mainly used in the protection of sensitive microelectronics, signal lines and data lines from the damages caused by over voltage and over current conditions.

Working Principle

The working principle of a SA58CAHE3/54 TVS diode is based on the breakdown phenomenon which happens when an excessive amount of voltage is applied. The diode acts as a reverse biased PN junction, and when a certain threshold voltage is reached, the diode breaks down and begins to conduct current. This effectively clamps and absorbs the excess electrical energy, protecting the sensitive device from damages.

These diodes are designed to absorb high surge currents upto maximum peak pulse power of 150W at 8/20µs for make-it or break-it time of up to 50ns. They also have excellent withstand properties against environmental stresses like moisture, shock, vibration, temperature and humidity.

SA58CAHE3/54 TVS diodes are a reliable, safe, and cost-effective way to protect sensitive devices from over voltage and over current conditions.
