Dummy load question

[pwNd]

Hi, can anyone tell me if i can use one 1 ohm resistor, 2 1n4004 diodes, and 4 1n4007 diodes to create test load for phr 803t. Im asking this because i cant get any 1n4001 diodes in Croatia. Thx for your help...:bowdown:

i don't know if you can make it with 2 4001 and 4 4007 but you can do it with 6 4007
thats how i make mine.

Can someone answer my question? I cant get two more 1n4007 diodes right now and I need a test load...

Thanks!

Laser driver dummy load - $10.99 : Modwerx Shop

You can buy the dummy load here for 11$

Omg!, im asking simple question, can someone answer it, not give me the alternatives...

dont get rude... its not appreciated...

you can use any of the 1n4xxx diodes if im not mistaken.

I would assume that if the design calls for 6 4007, you cant replace 2 for 2 different ones.
Unless 4004/4007 specs are identical.

I wasnt rude, i just asked a question, i didnt ask how i can get dummy load. Sry to everyone who got insulted by my posts

Btw drew can u test it if u have proper dummy load. You know, connect proper dummyload, and measure the v and ma, then make one from 4 4007 and two 4004 and 1ohm resistor and then measure again to see if its same. Ofcourse, if u have these diodes.
Thanks!

All 1N400x diodes have the same voltage drop (within a few mVs), the last digit refers to the breakdown voltage of the diodes. So yes, you can mix and match.
