ESDALC5-1BT2 is a series of transient voltage suppressors (TVS) diode, which is designed for ESD protection with low capacitance and low clamping voltage. It is used in electronic circuits to protect against ESD, Electrical fast transient (EFT) and lightning surge.

Application Field

The ESDALC5-1BT2 TVS diode plays an important role in the protection of the integrated circuit, especially in the port which may be exposed to the shock of electrostatic or lightning surge. The main application field of the ESDALC5-1BT2 includes mobile phones, LCD display, USB, HDMI, DisplayPort and other high-speed interfaces.

Working Principle

TVS Diodes use a unique avalanche breakdown principle to absorb the incoming surge and voltage spike on a single diode. When the amount of voltage spike or surge exceeds its breakdown voltage, it will allow current to flow through it and absorb the excess voltage. During the absorption process, the power dissipated within the die is converted into heat and then the heat is dissipated to the ambient.

The ESDALC5-1BT2 TVS diode has two characteristics, low capacitance and low clamping voltage. The low capacitance can reduce the signal distortion caused by parasitic capacitance, while the low clamping voltage can protect the ESD sensitive devices from over voltage conditions. Under normal conditions, the clamping voltage is typically 8.3V in 1.5KW surge current and 2.7V in 1uS (uni-directional).

In conclusion, ESDALC5-1BT2 is a TVS diode, which is mainly used for ESD/EFT/Lightning Surge protection. It has good low capacitance and low clamping voltage and is widely used in digitizing equipment.
