SMT Equivalent for 1N4004

Thanks guys for your input! I erred with the temp spec. It should be -55 to

+175 C, same as for 1N4004 diode.

SMB package is too big. If there is a device about half the size of an SMB,

that would work perfectly.

The size of a 1/4 W chip resistor would be great!

A MELF might possibly work but rolling off the pad is not good here.

Hello Biff !:

Greetings,
Can you tell me a part number(s) for a 1N4004 surface mount equivalent.

I need a small as possible package with the component temperature ratings
@ -65 to 175 C

SM4004 ! (or SM4007) - Typical MELF package.

You can search for other diodes because MELF is not easy to solder due to
quick roll off pad :-(.

Best temp range have glass packages.

A common type is the LL4004 (MELF package). I personally prefer SMA

package for easier handling, look for S1D or the like.

"As small as possible" depends on your current requirements. And your

specified temperature range definitely is a problem - the 1N4004 also

doesn't match it. Besides that, at these temperatures you'll run into

/many/ problems - with PCB material and all other components, too.

Thanks very much for help.

A simple search like 1N4148 SMD will do that.
