This document describes the features and characteristics of the BZV47C series 2W silicon Zener diodes, including voltage range, package type, high surge capability, etc.
The BZV47C series are 2 W silicon Zener diodes offered in a hermetically sealed plastic (F126) case. They provide voltage regulation from 5.1 V up to 200 V and feature high surge capability of 55 W for 10 ms pulses.
Key specifications include a maximum junction temperature of 175 °C, thermal resistance of 60 °C/W (junction‑to‑lead) and 100 °C/W (junction‑to‑ambient on a standard PCB). The devices are supplied in standard tape‑and‑reel packaging with dimensions such as 6.05 mm × 2.95 mm for the A and C rows. This manual is written in Chinese.
