CD214B-T100ALF is a TVS diode designed to protect sensitive electronic components from high-energy voltage discharges such as electrostatic discharge (ESD), high-current transients, and lightning strikes. TVS diodes are active components used to protect valuable and sensitive devices from ESD, lightning, and other electrical overvoltage events.

The CD214B-T100ALF is a dual common-anode bi-directional TVS diode rated for working voltages up to 100 V with a peak pulse current of 200 A. It features a fast response time of 0.5 ns in the case of energy pulses and is stable over a wide frequency range from 1 megahertz to 400 megahertz. Additionally, the device includes two independently controlled transistor elements for bi-directional ESD protection.

The CD214B-T100ALF is designed for use in a variety of applications, including consumer electronics, automotive, industrial control, and medical equipment. It can be used to protect against ESD voltages and transients caused by a variety of sources, including electrostatic discharge, lightning, high voltage induction pulses, and contact with high voltage sources. Additionally, the device can be used to protect data communications cables from EMI/RFI interference.

The working principle of the CD214B-T100ALF is based on a Silicon-controlled Rectifier (SCR) operating in avalanche mode. When an ESD pulse enters the device, the voltage across the SCR will exceed its breakdown voltage, allowing current to flow through the device. This current flow will cause a large voltage drop across the TVS diode, which will absorb the energy of the ESD pulse and prevent it from causing damage to the protected component.

The CD214B-T100ALF also features a novel dual transistor feature. This feature enables the device to protect both sides of a circuit from ESD pulses. When an ESD pulse enters the device, one of the two transistors will begin conducting current, allowing the other transistor to remain idle and not be affected by the ESD pulse. This feature allows for more efficient ESD protection and provides greater flexibility in circuit design.

In conclusion, the CD214B-T100ALF is an ideal choice for circuit protection from ESD and other electrical overvoltage events. It is designed for use in a variety of applications, including consumer electronics, automotive, industrial control, and medical equipment, and features a fast response time and dual transistor protection for superior circuit protection.
