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.

Some manufacturers have a generic type coding scheme for MELF and mini-MELF diodes.
That for Vishay/General Semiconductor is shown below:

Kt Kingtronics diode rectifiers
 
Do you know diode? A diode is an electrical device allowing current to move through it in one direction with far greater ease than in the other, which used in very wide range in our life. Obviously, diode usage is very huge in the market!
 
Here I would like to introduce our kingtronics strong diode rectifiers.
 
Kingtronics international company, a Hong Kong based manufacturer, all products are pruduced under our own brand kingtronics. And we have three trademarks, Kt, Kingtronics, King.
 
Kingtronics offer wide range diodes, most strong offer diode M7(SMD4001-4007). Fast switching diode LL4148 Minimelf SOD80. Zener diode BZV55C & ZMM55C.
 
Other popular didoe like general purpose plastic rectifier, sillicon rectifier, fast recovery diode, schottky barrier rectifier, Silicon Epitaxial Planar Switching diode etc.
 
Now our brand have good reputation in the market, because all our products with excellent quality, and very competitive price! Choose Kingtronics, you won't feel down!

Dear purchsers and sales,
 
How is your work going recently?
 
From this year, Kingtronics products have a great improvement on price and delivery. Take zener diode as an example, we adjust its price, and some are even lower than before.
 
Because it has a large consumption on manufacturing such as protector and heat controller, I believe you will benefit a lot from our price down.
