SMAJ16-E3/5A

Transient voltage suppressors (TVS) are semiconductor electronics components designed to protect electronic circuits from damage due to transient voltage. A stellar example of such a device is the SMAJ16-E3/5A from Taiwan Semiconductor.Thanks to its unidirectional and low capacitance properties, SMAJ16-E3/5A is an ideal choice for consumer and professional applications requiring ultra-fast clamping response to overvoltage conditions.

Application Field

SMAJ16-E3/5A is designed for protecting high speed data and communication lines against electrostatic discharge (ESD) and transient electrical events. It is used in Ethernet and USB ports, I2C buses, automotive diagnostic ports, touch screens, mobile devices, serial/parallel interfaces, audio/video ports, RF devices, telecommunication interfaces, and other consumer and professional applications.

Working Principle

When an external transient voltage is applied, the SMAJ16-E3/5A clamps the voltage by reducing its amplitude. This is accomplished by redirecting the current created by the transient voltage through its series diode, allowing a two-terminal device to behave like a small, highly efficient, and low capacitance capacitor. The protective action of the SMAJ16-E3/5A is fast and efficient due to its ultra-short response time.

The SMAJ16-E3/5A also has peak pulse power capability of 500 watts, high breakdown voltage (16V) and low leakage current (5mA maximum), making it effective in a variety of applications. In addition, the SMAJ16-E3/5A is RoHS compliant and is available in lead free packages.

Overall, the SMAJ16-E3/5A is an excellent choice for protecting electronic circuits from transient voltage and electrostatic discharge. Its superior durability and ultra-fast response time make it suitable for numerous applications, from consumer devices to professional equipment.
