CM1220-08CP is a high speed, bidirectional suppressor diode with two sets of symmetrical contacts. It is commonly used in TVS - Diodes applications.The CM1220-08CP is a semiconductor device designed to protect sensitive equipment such as automotive, medical, communications, and industrial from the damaging effects of Electrostatic Discharge (ESD), EMI/RFI and lightning surge. It features an advanced design, which allows for higher performance and low capacitance in a small, surface mount package. It is a unidirectional diode that is designed to protect sensitive circuits from voltage spikes and surges caused by electrostatic discharge or transients. The device is bidirectional, meaning it can protect circuits from both positive and negative electrical pulses.The CM1220-08CP is designed to conduct a wide range of transient energy, allowing it to protect systems from both man-made and natural transients such as lightning or ESD. It has a fast response time and can dissipate up to 2W of energy making it ideal for high-speed signal protection applications. Its shallow doping profile helps reduce capacitance to as low as 0.3pF, making it ideal for high-speed electronics such as USB and HDMI.In terms of its working principle, the CM1220-08CP employs avalanche breakdown. When a transient voltage exceeds the breakdown voltage of the CM1220-08CP, typically 15V to 20V, it enters into avalanche breakdown mode. This mode is characterized by a region of negative differential resistance and significant increases in current conduction. During avalanche breakdown, the diode begins to clamp and reduce the voltage across its terminals until the voltage reaches the clamping voltage, typically 1.5V. Current continues to flow until the energy of the transient dissipates. The CM1220-08CP then returns to its nonconductive state.The CM1220-08CP can be used in a variety of applications, including data line protectors, sensitive analog signal protection, industrial motor control circuits, and automotive applications where low voltage transients and ESD protection are required.The CM1220-08CP is an excellent choice for many TVS - Diodes applications because it features high speed, low capacitance, shallow doping, and low voltage clamping characteristics. This makes it ideal for protecting sensitive equipment. The device’s fast response time also makes it suited for high-speed signal protection applications such as USB and HDMI. It can effectively protect against numerous types of transients, making it a reliable choice for many different types of applications.
