Diodes - Zener - SingleThe SMAJ4764CE3/TR13 is a single zener diode that is designed to protect various electrical and electronic components from potentially damaging electrical surges. It is used primarily in protecting digital information processing and telecommunications equipment, as well as other digital and electronic components, against transients caused by externally connected devices.The SMAJ4764CE3/TR13 diode comprises of a low breakdown voltage, high junction reverse breakdown voltage, and low surge current ratings. The device features an Ultra Low Capacitance (ULC) circuit structure for improved high-frequency characteristics, together with increased thermal performance. The device is manufactured in a Pb (Lead) free, RoHS compliant surface-mount package, with speed and power capability suitable for high-frequency, high-performance applications.The SMAJ4764CE3/TR13 diode works by quickly shunting away the surge current when a di/dt transient occurs. This reduces the damaging effects of these events on the connected device. The diode is designed to tolerate high peak power dissipation, as determined by its VZK rating, while maintaining low clamping voltage.The main application field of the SMAJ4764CE3/TR13 Zener diode is in consumer electronic devices and industrial and automotive control systems. In consumer electronics, the device is used for the protection of audio and video equipment, personal electronics, home automation equipment, and industrial systems. In automotive applications, the diode is used for protection of the interior and exterior lighting systems, gauges, sensors, motors, and circuits.The SMAJ4764CE3/TR13 Zener diode works by effectively providing a short conducting path for the surge currents after the peak voltage has been reached. This is because the reverse breakdown voltage of the diode limits the surge transient voltage by diverting it away from the protected device.The working principle behind the SMAJ4764CE3/TR13 diode is based on the zener breakdown phenomenon, which is a phenomenon in semiconductor materials. When a reverse-biased voltage is applied across a semiconductor material, it distorts the density of charge carriers inside the material and creates a void of electron deficiency, which is known as the zener breakdown. As a result, a small electric current can flow across the device under reverse-bias conditions.The SMAJ4764CE3/TR13 device is designed to provide maximum protection when it is used in conjunction with transient voltage suppression (TVS) devices. It optimizes protection with a low capacitance and high breakdown voltage of 6.2V and 5.3V respectively. When used in a TVS circuit, the Zener diode works in conjunction with other components to provide increased surge protection. The device is also suitable for applications with high dv/dt and high failure-rates, providing a very stable and precise protection system.In conclusion, the SMAJ4764CE3/TR13 Zener diode offers excellent protection against electrical surges and voltage transients in digital and electronic components. This diode is designed to withstand a wide range of power surges, allowing for safe and reliable operation of the protected device. It is ideal for use in a wide range of applications, from consumer electronics to automotive and industrial systems.
