TVS (Transient Voltage Suppression) diodes are specialized diodes commonly used in electronic circuits for protection against electrical transients. 1.5KE13-E3/73 is a voltage-dependent TVS that has been designed and manufactured by Littelfuse Inc for general use in electronic circuits.

The 1.5KE13-E3/73, a unidirectional device, has a polarity sensitive zener diode and series resistor for transient clamping. It offers protection against is low-level transients caused by ESD or inductive kickback. The device is constructed of a low-profile P600F molded plastic body that acts as a 14 kV ESD protection body. The voltage level varies with the input current and the maximum clamping voltage is 13.2V.

The 1.5KE13-E3/73 is typically used in a wide variety of applications, such as in mobile phones, communication equipment, personal computers, and instrumentation.

The 1.5KE13-E3/73 TVS works by diverting or clamping high-voltage transients to an acceptably low voltage level. This is accomplished with the assistance of a zener diode and a series resistor. When a high voltage transient appears, the PN junction of the diode starts to breakdown, and extra current is taken by the series resistor from the applied voltage. This prevents the applied voltage from reaching the device threshold. With the help of the series resistor, the current is limited and the voltage drop across the device is limited, resulting in the effectively lower voltage at the TVS.

The device is usually mounted on a printed circuit board in order to route the transient current away from the vulnerable components. The 1.5KE13-E3/73 diode is designed for use in surface mounting applications. Most commonly it is installed in production lines during the reflow process. The device is available in multiple packages, such as in SMA and SMAF packages.

In summary, the 1.5KE13-E3/73 is a voltage-dependent TVS diode that offers transient protection against high voltage transients. It can be used in a variety of applications to limit transient voltage and ensure the safety of circuits and components. It is an ideal solution for high-performance, low-profile, and cost-effective transient protection applications.
