CDBM120-HF is a single diode rectifier that is designed to provide electrostatic protection, dampen ringing, and improve immunity performance in high speed I/O applications. It features an extended operating temperature range of -55℃ to 150℃, a fast switching speed (F max ≥ 1.8 × 106A/µs), and a peak reverse current (IFM ≤ 1.4A). It is suitable for applications such as computer systems, telecommunications, and industrial components.The working principle of the CDBM120-HF is based on its rectifier design. A rectifier is an electronic device made up of diodes that allow the flow of current in one direction only. In the case of the CDBM120-HF, it is designed with two diodes in a single package. One diode is the anode and the other is the cathode. When a current is applied to the device, the anode diode will conduct and the cathode diode will block the output current, only allowing it to travel one way. This rectification process helps to protect connected devices in high speed circuits from static and transient voltages, helps reduce noise, and improves immunity performance.The CDBM120-HF also has a built-in spike protection feature that helps to dissipate ESD and over-voltage from connected devices in a short period of time. It is capable of withstanding up to 25kV ESD and 18.75V transient voltage, making it suitable for use in systems with high speed data rates requiring robust protection. In addition, it has a low forward voltage drop (VF ≤ 0.9V) and a low reverse recovery time (t RR ≤ 30ns).The CDBM120-HF is available in an industry standard package and has an operating temperature range of -55℃ to 150℃, a storage temperature range of -65℃ to 150℃, and a junction temperature of 175℃. It is available in a variety of voltage ratings, including 3V, 5V, 9V, 12V, and 15V. The device is constructed using qualified materials that meet UL94V-O flammability rating and is the ideal choice for high speed applications.Overall, the CDBM120-HF is an ideal single diode rectifier for applications that require electrostatic protection and enhanced immunity performance. It provides fast switching speeds, low forward voltage drop, high surge protection, extended operating temperature capabilities, and an industry standard package. As such, it is a versatile and reliable product for use in a variety of high speed applications.
