CD214A-B220LF

The CD214A-B220LF is a rectifying diode that belongs to the family of single diodes. This component is a junction diode with a very high peak repetitive reverse voltage (VRRM) of 100V, low forward voltage drop (Vf) of 0.53V, and low reverse leakage current (IR) of 20mA. It is designed for use in applications such as reverse battery protection, AC-DC converters and in high-voltage switching power supplies.

This diode is made from an epitaxial construction with an anode contact and a cathode contact, and it is cased in a lead-free package. It is suitable to use in medical and other high reliability applications that require lead-free components. The CD214A-B220LF has a max junction temperature of 135°C, making it suitable to use in harsh environments.

The main application field of the CD214A-B220LF is AC-DC converters. When used in these converters, it can regulate the AC current, preventing it from going backwards. The diode provides an easy and cost effective solution for this application and improves the efficiency of the system. It can also be used to provide reverse battery protection, which prevents current from damaging components on the circuit when the battery is connected in the wrong polarity.

In addition, the CD214A-B220LF can also be used in high voltage switching power supplies. This diode is designed for high frequency applications, and it has a high relatively low forward voltage drop and reverse leakage current, making it suitable for this purpose. The diode helps to regulate the current and provides a more efficient solution for power supplies.

The working principle of this diode is based on the principle of PN Junction. It consists of two regions with opposite polarities, the P-type and the N-type. The P-region has more positive charge than the N-type, and the N-region has more negative charge than the P-type. When a reverse bias is applied, the depletion layer expands, preventing current from flowing. When a forward bias is applied, the depletion layer shrinks, allowing current to flow.

In summary, the CD214A-B220LF is a single rectifier diode used in AC-DC converters, reverse battery protection, and high voltage switching power supplies due to its ability to regulate the AC current and providing reverse protection against wrong polarity connections. The diode is made from epitaxial construction with an anode and cathode contact and it is cased in a lead-free package suitable for medical and other high reliability applications. The diode works based on the PN junction principle, and it has a reverse voltage of 100V, low forward voltage drop and low reverse leakage current.
