1.5KE400AHA0G

TVS - Diodes provide protection to electrical devices against transient surge voltages, ensuring the safety of circuit components and devices, and preventing damage to sensitive electronic components. The 1.5KE400AHA0G is a unidirectional TVS diode with a 400 Watt peak pulse power dissipation and a transient, or "clamping", voltage of 1500 volts. It is designed to protect against voltage transients caused by electrostatic discharge (ESD) and inductive switching. The 1.5KE400AHA0G comes in a compact DO-213AB surface mount package.

Application Field

The 1.5KE400AHA0G is designed to protect sensitive components and devices from transient voltage surges. It is suitable for a wide range of applications, such as automotive systems, industrial motor control systems, television sets, data communication equipment, and power supplies. Its low reverse leakage current and fast response time make it suitable for use in signal conditioning and power distribution networks.

Working Principle

The 1.5KE400AHA0G uses a junction between p-type and n-type semiconductor materials to provide active protection from transient voltage surges. The device acts as a high-voltage clamp, directing the surge current away from circuits and devices. When the voltage across the device rises to a certain level, the device enters a breakdown region and conducts current, clamping the surge voltage to its breakdown point. When the surge voltage falls below the breakdown point, the diode returns to its high-resistance non-conducting mode.

The 1.5KE400AHA0G is designed to protect against a wide range of transient surge voltages, including those caused by electrostatic discharge (ESD), inductive switching, and line induced or RF transients. The device features an ultra-fast response time, low capacitance, and low internal power consumption for minimal circuit disruption, as well as a high peak pulse power capability for improved protection.

In addition, the 1.5KE400AHA0G features a low forward voltage drop and low reverse leakage current, making it suitable for use in signal conditioning and power distribution networks. The device is also RoHS compliant and lead-free, making it a more environmentally friendly choice for a wide range of applications.

The 1.5KE400AHA0G is a highly reliable TVS diode designed to provide superior surge protection for a wide range of applications. With its compact size, low power consumption, and fast response time, it is an ideal solution for protecting sensitive electronic components against transient surged voltages.
