TVS (Transient Voltage Suppressor) – Diodes are essential components designed to protect against excessive voltage caused by electrical disturbances, like electrical overstress (EOS), electrostatic discharge (ESD), lightening, and inductive switching. 1.5KE8.2-E3/73 is a Bi-directional TVS Diode that helps protect against ESD and transient voltage spikes. It is commonly used in many applications across various industries.

Application Field

1.5KE8.2-E3/73 TVS Diode is most commonly used for circuits that need protection against ESD an transient voltages spikes due to its capability to suppress any excessive voltage. The applications that this device covers are in consumer electronics, ITs, Automotive, Automation, Telecommunications etc. The device is available with different packages and almost all packages support the same automotive standard of AEC-Q101.

In consumer electronics, 1.5KE8.2-E3/73 is mainly used for protecting USB and HDMI ports, data lines, and audio lines against ESD and transient disruptions. In ITs, this component is used for protecting data lines, Ethernet ports, USB ports, and signal lines against ESD and transient. In automotive, it is used for protecting ECU circuits, linear and switch circuits, and Body Electronics.

Working Principle

The working principle of 1.5KE8.2-E3/73 TVS diodes is quite simple. When a voltage passes through the device, the internal structure of the diode causes the voltage to be discharged and clamped to a safe level. When a transient voltage rises too high, the diode would absorb and “clamp” the excess energy, and allow the charge to flow quickly away from the sensitive components, thus protecting them from overload and accidental damage.

This TVS diode has an electro-thermal dissipation capability of 1.110 W, making it suitable for clamping 5Amp currents in less than 1ns. The device also comes with a clamping voltage of 5.8V and an ESD stand of IEC 6100-4-2 (Level 4, Criterion B).

In conclusion, 1.5KE8.2-E3/73 TVS Diode is a reliable, cost-effective choice for protecting circuits from ESD and transient voltage spikes. It is widely used in consumer electronics, ITs, Automotive, Automation, and Telecommunications.
