SMAJ4468CE3/TR13 Application Field and Working Principle

Diodes - Zener - Single

The SMAJ4468CE3/TR13 is an ultra-fast Zener diode which can be used to provide overvoltage protection in a wide variety of electronic circuits. It is designed to meet the needs of low voltage, high-current applications, such as power supplies, professional audio systems, and automotive electronics. The package size is also suitable for portable devices such as cellular phones and medical equipment.

The SMAJ4468CE3/TR13\'s unique design enables it to provide fast and reliable overvoltage protection while dissipating very low power. It features an operating temperature range of between -55°C to +150°C and a maximum operating voltage range of up to 24V.

A key feature of the SMAJ4468CE3/TR13 is its reverse polarity protection, which prevents a reverse current from being drawn into the device in the event of an external voltage reversal. It also features a low clamping voltage and excellent dynamic impedance characteristics, enabling it to protect electronic systems from high-voltage transients.

The operating principle of the SMAJ4468CE3/TR13 is relatively straightforward. Its construction consists of two layers of N-type and P-type semiconductor material. When a voltage greater than its forward voltage rating is applied across it, the electrons in the N-type material are attracted to the P-type material, creating an area of negative charge.

This in turn creates an electric field which generates an opposing current. This counteracting current limits the applied voltage, thus protecting the connected device. The SMAJ4468CE3/TR13 also features a protective diode which prevents reverse current flow which could damage the device.

The SMAJ4468CE3/TR13 can be used in a wide variety of applications, such as power supplies, industrial automation control systems, audio systems and even cell phones. It is available in a variety of sizes, from the ultra-small SMAJ2.4 size to the SMAJ100 size, which can handle up to 100V.

The SMAJ4468CE3/TR13 is an ideal solution for providing reliable overvoltage protection. Its small size, low power dissipation and high temperature tolerance make it an ideal choice for many applications.
