The following is a detailed introduction to the DW52C11LED02 voltage regulator diode (WBFBP02C package), based on technical data compiled by Jiangsu Changdian/Changjing (JCET) brand:
1、 Product Overview
DW52C11LED02 is an ultra small voltage regulator diode (Zener diode) produced by Jiangsu Changdian/Changjing (JCET), using WBFBP02C surface mount packaging. Its core function is to provide a stable voltage reference for the circuit, clamp the voltage near the nominal value through the Zener breakdown effect, and be suitable for precision voltage regulation, overvoltage protection, and other scenarios. Its compact packaging size (1.0mm × 0.6mm) is suitable for high-density PCB design.
