Hi all,
I am trying to find this smd , maybe a diode?
It is marked PJ9345 M4 and it is located in a board used for opening and closing a door ,
The board is fed with 30V and it regulates 2 relè for closing and opening a door through 2 electric motor door.
Attached is a photo of the board, the red wire is part of my repair attempt after the board is was fedded with 220v in the closing /open /com control line.

Thank you
Andrea

 

Hello,

The M4 parts are rectifying diodes.
See the attached datasheet.

Thank you very much !!
Do you think I could use an IN4007 instead?
I found another broken component is a MOSFET QM6016D but I can't find it Can you suggest me a replacement?

thank you
Andrea

 

Hi guys, this component is blown up can someone point me in the right direction to replace it?
Thank you
Andrea

 

In4007 will work.

Thank you very much! I replaced the diode and now the relè works. I am missing the MOSFET , thank you for the datasheet, but I am unable to source that part. I checked Digikey RS and Farnell any idea where I could find it?

 

At digikey.com search for MOSFET. Then choose single. Next check the "in stock" box, N-Channel, Drain to Source Voltage I selected 60 through 80 volts, Apply All
Then I went back and looked for RDSon of 12 mohm through 6m ohm. Apply All
Then I chose all the TO-252 and TO-262 type packages. Apply All
Some of the parts are right package but not surface mount so click that button and apply.
digikey mosfet 60V Here is the search so far. Some of the packages are wrong but getting close.
Some of the parts have 2 pins + heatsink and some have 3 pins but that is OK. Pick either.

You should double check my work. I make mistakes.
