CDBM260-G

Diodes are an important component in most electrical and electronic circuits, and Rectifiers - Single are diodes that are used mainly to convert alternating current (AC) to direct current (DC). The CDBM260-G is a Rectifier - Single diode designed to do precisely this.

The CDBM260-G rectifier diode has a maximum repetitive peak reverse voltage (PRV) of 200V, a maximum continuous forward current of 1.0A, a maximum non-repetitive surge of 1.0A, and a junction temperature of 175°C. It has a forward voltage drop of 0.85V at 1A, and is optimised for most fast recovery mode PFC power supplies.

The maximum power dissipation of the CDBM260-G is limited to 2W, as it is a small device with a total package size of 0.59mm x 0.59mm. The CDBM260-G is normally used in various industrial, commercial and consumer power supplies, as well as for applications such as solar panel string rectification.

The working principle of the CDBM260-G is to efficiently convert AC current to DC current by blocking current in one direction while allowing it to pass through in the opposite direction. When the input voltage is applied across the cathode and anode of the diode, the anode current is allowed to flow in one direction, while the cathode current is blocked in the other direction. During the reverse bias condition, the applied voltage is higher than the breakdown voltage.

The CDBM260-G is designed to work in the Avalanche, Forward and Reverse biasing conditions, and is designed to switch very quickly between them. The device features a very low junction capacitance of only 4.5pF, which helps to reduce power losses and improve efficiency. It also features low leakage current of 1.2uA and fast recovery time of 45ns.

The CDBM260-G is capable of operating at frequencies up to 1MHz and it is also immune to current transients and voltage spikes. It has a low reverse recovery time of 30ns and a low forward recovery time of 38ns. It is rated to withstand temperatures up to 175°C and provides excellent protection against thermal, mechanical and electrical stress. Finally, all of these features combined with its low cost and small size make it ideal for a variety of applications.
