MELF/mini-MELF/LL-34 Package Diodes
The SOD-80 package, also known as mini-MELF, is a small ( glass, sometimes plastic) cylinder with metal ends.
Our Kingtronics mostly use package LL-34. Below information is for your reference.
MELF package: L=4.9mm; D=2.5mm
MINI-MELF (SOD80C): L=3.5mm; D=1.6mm
LL-34: L=3.4mm; D= 1.4mm
Code marked devices:
Marked C2V4 TO C75 BZV55 series 500mW zener diodes (2.4 - 75V), also our BZX55C series, our factory stong zener diode.
The cathode end is indicated by a coloured band.
Some Coloured band marked devices (MELF/SOD-80), it's for your reference.

Kingtronics International Company was established in 1995 located in Dongguan City of China to handle all sales & marketing for factories located in Chengdu, Sichuan and Zhaoqing, Guangdong, China. In 1990, we established the first factory to produce trimming potentiometer and in 1999 we built up new factory in Zhao Qing, Guangdong. Now with around 850 workers, Kingtronics produce trimming potentiometers, dipped tantalum capacitors, multilayer ceramic capacitors, and diode & bridge rectifier. We sell good quality under our brand Kingtronics, and Kt, King, Kingtronics are our three trademarks. All our products are RoHS compliant, and our bridge rectifier have UL approval. Please visit our Products page, you could please download all our PDF datasheet and find cross reference for our Trimming Potentiometer and capacitors.
