    guys I'm looking for general purpose diode like 1N4148.
    it should be small.(smaller than 1n4148).
    surface mount solution is not going to work as they are very expensive.

    I'm working on a circuit and need to use parts small as possible. i use 1/8w resistors and 1n4148 as diodes as they are small.

    can you suggest me any diode that has smaller size than 1N4148?

    current ratings are not a problem.

    thanks

    Here's what you can get -

    [SIZE=+1]Dimensions of 2-lead diode packages, as length x width x thickness
    [/SIZE][SIZE=+1]or length x diameter (mm)[/SIZE]​

    Package Size Manufacturer EMD2 1.2 x 0.8 x 0.6 Rohm PMDT 3.8 x 2.4 x 0.95 Rohm PMDS 4.5 x 2.6 x 2.0 Rohm PMDU 2.6 x 1.6 x 0.8 Rohm TUMD2 1.9 x 1.3 x 0.6 Rohm UMD2 1.7 x 1.25 x 0.7 Rohm VMD2 1.0 x 0.6 x 0.5 Rohm VMN2 0.9 x 0.6 x 0.4 Rohm LLDS 3.4 x 1.5Ø Rohm MELF 4.9 x 2.5Ø

    Don't know why, but the link is flawed. I'm not authorized to view that page.

    well how to ask for them?
    just as only "1N4148" or anyother way?

    Hi,

    Surface mount 1N4148 diodes can be purchased for as little as 1 British penny each on E-bay. I have bought full reels of them (5000 diodes) for 8 GBP a reel on E-bay.

    Good luck.

    Daniel.
