Transient Voltage Suppressor (TVS) diodes are protective components used in a variety of circuit designs and systems for providing overvoltage protection. SMCJ220CAE3/TR13 is a popular TVS diode used for protection in a number of applications. This article will discuss the application field, the working principle, and some of the features of the SMCJ220CAE3/TR13.

Application Field

SMCJ220CAE3/TR13 can be used to protect sensitive equipment from high voltage transients in a variety of environments, including automotive applications, consumer appliances, cell phones, and instrumentation. The SMCJ220CAE3/TR13 is a high-speed diode designed for high-energy transient protection. It can handle 500 W peak power dissipation, making it suitable for short-term protection in applications where high-power pulse currents are expected.

Working Principle

The SMCJ220CAE3/TR13 is a Uni-directional type TVS diode with a bi-directional junction. It is designed to offer effective protection from overvoltage transients. The diode acts like a short circuit, clamping the voltage at a low level until the transient subsides. When a voltage transient is applied, the device quickly switches from a non-conductive to a low-impedance conducting state. As the voltage increases beyond a critical level, the diode switches to an active state and begins to reduce excess voltage through the series resistance of the device. The device continues to remain in its conducting state until the voltage returns to a safe range.

Features

The SMCJ220CAE3/TR13 has a maximum peak pulse power rating of 500 W (10/1000 μs) with a clamping voltage of 220 V. It features a very fast response time, with typical values ranging from 6 ns to 10 ns. The device also has a very wide operating temperature range from -55°C to 150°C, making it suitable for extreme temperature conditions. The SMCJ220CAE3/TR13 offers excellent surge immunity and superior electrical performance, making it an ideal choice for a variety of applications.

The SMCJ220CAE3/TR13 is designed to provide reliable protection to systems against overvoltage transients.
