Transient voltage suppression (TVS) diodes, also known as surge suppressors, are useful components that protect connected systems from high voltage and transient current generated by electrostatic discharge (ESD), electrical fast transients (EFTs), and lightning induced surges. The SMDJ28CA is an unidirectional, 250W, 28V TVS diode designed to help protect high power systems from transient surges caused by ESD, EFT, and other sources.

The SMDJ28CA consists of a zinc-oxide layer bonded to two silicon diodes of opposite polarity. It has an operating temperature range of -55°C to +175°C, and uses a radial leaded package with environmental protection coating. The SMDJ28CA can handle up to 28V and offers a low clamping voltage and low leakage current.

The SMDJ28CA is used in many applications, such as computers, telecom equipment, automobiles, industrial control, military and aerospace systems, consumer electronics, and medical equipment. This TVS diode is designed to protect circuits from over-voltage transients, induced spikes and other surges caused by lightning. It also suppresses high voltage and transient current when there is an ESD event, providing the ultimate protection to the connected system.

The working principle of the SMDJ28CA is simple. When high voltage or transient current occurs, the TVS diode begins to conduct and divert the current away from the load. This will in turn reduce the voltage across the load to a safe level. This prevents the connected system from experiencing any potential damage from the surge. The diode will then reset itself, allowing the system to continue functioning as intended.

The SMDJ28CA is a reliable and robust solution for protecting high power systems from transient surges caused by ESD, EFT, and other sources. It features a very low clamping voltage and low leakage current, making it an ideal choice for a wide variety of applications. With its wide operating temperature range and environmental protection coating, the SMDJ28CA provides reliable protection to the connected system, even in harsh environments.
