SA28C Circuit Protection

TVS - Diodes

A transient voltage suppressor (TVS) diode is an electronic component designed to protect electronic devices from damage caused by transients — brief voltage surges that can occur due to lightning, electric motors, switching power supplies, and other sources. TVS diodes are also known as high-reliability TVS (HTRTVS) devices or transient voltage protection diodes (TPD).

SA28C Application Field and Working Principle

The SA28C is a heavy duty TVS diode designed for use in telecommunications, satellite, and power line applications. It offers excellent protection against transient voltages up to 2000 volts, and it offers a low clamping voltage. The diode has an ultra fast response time of less than 1.0 ns, making it perfect for events such as electrostatic discharge. The diode also has a low input capacitance of 1 pF and is RoHS compliant.

The working principle of the SA28C is quite simple. It acts as a short circuit for transient voltages, ensuring that they do not cause any damage to the circuit that they are used in. The TVS diode is installed in series with the device that is being protected, and it will dissipate the excess voltage to ground before it can cause any harm. When the transient voltage is present, the SA28C will allow current to flow through the diode in order to protect the device.

The SA28C is designed to protect vulnerable electronic devices and components from transients that exceed normal operating levels. When a transient voltage occurs, the SA28C will absorb the energy and dissipate it to ground, preventing the device from being damaged. This makes the SA28C an ideal choice for protection against a wide range of over-voltage conditions.

The SA28C is a great choice for a wide variety of applications, and it offers excellent protection against transient voltages. Its low input capacitance and fast response time make it a great choice for protecting against electrostatic discharge and other over-voltage events. The SA28C is RoHS compliant, making it a great choice for any application where protection from transient voltages is required.
