TVS diodes are a special class of diode that are designed to protect against transient voltage surges that can be caused by several sources, such as electrostatic discharge, lightning, and switching transients. The 5KP48HE3/54 TVS diode is a unidirectional device designed specifically for interface protection applications, such as USB, HDMI, Ethernet, and mobile device applications. It provides protection against both ESD and lightning surges.

Application Field

The 5KP48HE3/54 TVS diode is designed for a variety of interface protection applications, including USB ( Universal Serial Bus ), HDMI ( High-Definition Multimedia Interface ), Ethernet, and mobile devices. It is rated for a maximum working voltage of 48 V and can provide protection against both ESD and lightning surges. It has a low clamping voltage and a fast response time, making it suitable for use with high-speed data lines.

Working Principle

The 5KP48HE3/54 TVS diode works by absorbing excess voltage that is present in the signal line. When a transient voltage surge is detected, the diode reduces the voltage on the signal line and diverts it to ground, thus preventing the voltage from reaching sensitive components. This helps to keep those components from being damaged by the surge.

The 5KP48HE3/54 uses an Opposite-Collector Absorbing technique to quickly and accurately detect transient voltage surges. This technique utilizes complementary switches and a pair of current sources to quickly detect the transient voltage surge. Once the surge is detected, the diode absorbs the excess voltage and diverts it to ground, providing protection to the components that may be affected by the surge.

The 5KP48HE3/54 is also designed to be robust and reliable, with low leakage current and high surge capability. It is RoHS compliant and has a small profile that makes it easy to integrate into most circuits. Additionally, it has a low profile design that helps to reduce size and weight in applications.

In summary, the 5KP48HE3/54 TVS diode is a unidirectional device designed for use in a variety of interface protection applications. It is designed for high-speed data lines and has a low clamping voltage, fast response time, and high surge capability. It is RoHS compliant and has a small profile, making it easy to integrate into most circuits.
