Introduction

SMLJ48CE3/TR13 is a semiconductor technology developed by STMicroelectronics. It is applicable for TVS (Transient Voltage Suppressor) diode series, and is particularly designed to absorb high surge pulses in order to protect delicate loads like sensitive electronic components from damage. The device is well suited for consumer applications such as personal computers, telecommunication systems, and other consumer devices which require high level of protection from overvoltages.

Overview

The SMLJ48CE3/TR13 TVS device is a three-line transient voltage suppressor with an operating voltage range of 1.5V to 24V. It has an ESD protection of up to 28.8kV and a peak pulse power rating of up to 1500W. The working principle of this device is to provide a clamp mechanism to limit the voltage surge to a safe level during overvoltage conditions. The device is also designed to have a fast turn-on time in order to quickly clamp the voltage and protect the delicate components from the excess voltage.
