TVS - Diodes: CD214B-T45ALF Application Field and Working Principle

TVS (Transient Voltage Suppressor) diodes are widely used in various electronic circuits to absorb sudden and extreme spikes in voltage that can damage or damage other components in the system. These diodes are designed with a wide range of thermal, electrical, and environmental properties to meet different design needs and applications. One of the commonly used TVS diodes is the CD214B-T45ALF. This article will discuss the application field and working principle of this TVS diode.

Application Field: The CD214B-T45ALF is a diode designed specifically for automotive applications. It is used to protect circuits from overvoltage and reverse polarity damage caused by accidents, surges, and shocks. It is suitable for use in car alarms, airbags, RADAR systems, air conditioning systems, and protection circuits. It is also used in automotive lighting systems, LED displays, automobiles, trucks, buses, buses, and motorcycles. Its low capacitance and wide operating temperature range make it an ideal choice for automotive applications.

Working Principle: The CD214B-T45ALF is a two-terminal, bilaterally symmetrical, bipolar junction transistor (BJT) based TVS diode. It has two diodes connected in parallel which can absorb the surge current. When a voltage surge occurs, the TVS starts conducting and clamps the voltage to protect the device. The two diodes increase the current capacity and voltage withstanding ratings of the TVS diode. The reverse breakdown voltage is between -15V and 10V, and the peak pulse power dissipation ranges from 300W to 400W.

In addition to protection, the CD214B-T45ALF also provides ESD protection, which helps to safeguard sensitive electronic components from damage due to electrostatic discharge. The diode\'s low capacitance and wide operating temperature range make it suitable for harsh environments. The CD214B-T45ALF is available in a variety of packages that are suitable for surface mount and through-hole applications. It is RoHS compliant and UL certified.

In conclusion, the CD214B-T45ALF is an ideal choice for automotive applications. It is a two-terminal diode capable of providing superior overvoltage protection and is designed for more demanding environments. The wide operating temperature range and low capacitance make it suitable for use in sensitive electronics. This diode is UL certified and RoHS compliant.
