TVS - Diodes: ESDA5-1F4 Application Field and Working Principle

The ESDA5-1F4 is a type of Transient Voltage Suppression Diode (TVS) that is commonly used in voltage protection applications. It has a peak pulse power dissipation rating of 2000 watts and a thermally coupled fast response time. This diode is used to protect circuits from overvoltage by clamping transient voltage spikes below predefined maximum values. It is also used in other voltage protection applications, such as rechargeable battery protection circuits, high speed data line protection, ethernet protection, and USB port protection.

Application Field

The ESDA5-1F4 has a high surge capability and is ideal for surge and transient protection applications. It is very robust and designed to offer maximum protection in the most demanding environments. It is commonly used in industries such as computing, consumer electronics, industrial and automotive applications. It is particularly useful for protecting against voltage spikes caused by EMI interference and lightning strikes. It can also be used to protect against sudden unexpected power surges, such as a sudden change in the output voltage of the power supply.

Working Principle

The ESDA5-1F4 operates on the principle of a break-over diode. It consists of two solid state devices, one pn junction diode and a zener diode. The diode is connected in series with the load and the power line. When the power line voltage exceeds the breakdown voltage of the diode, the diode will conduct current, clamping the transient surge voltage to the breakdown voltage. This allows the diode to protect the circuit from the overvoltage while preventing the current in the circuit from exceeding the breakdown voltage.The ESDA5-1F4 is constructed to be very robust and has a low thermal resistance. This allows it to survive high surge currents without any damage. It also offers a fast response time of less than 1 millisecond, which is necessary for protection against high-speed data line applications. It also has a wide operating temperature range of -55°C to +125°C.

Conclusion

The ESDA5-1F4 Transient Voltage Suppression Diode (TVS) is a robust device designed for use in surge and transient protection applications. It has a peak pulse power dissipation rating of 2000 watts and a thermally coupled fast response time of less than 1 millisecond. It is well suited for protection in high speed data line applications and operates on the principle of a break-over diode. It is commonly used in industries such as computing, consumer electronics, industrial and automotive applications.
