Kt Kingtronics Diodes Package Introduction

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.
