Wisam Naji 3 2. I have a no frost freezer which stopped freezing efficiently and after some research and trials I found the problem to be related to control board.

But constantly replacing diodes while investigating another problem can get tiring. The relay use 24 vdc and if the voltage across the coil keeps fluctuating around 24 then tramsistor this what you mean by actuating the coil more frequently and could have burnt the diode.

I suggesting putting the two smaller, faster diodes in series so they have a higher turn on voltage than transjstor slower 1N or 1N parallel to them – so they will only take the back EMF until the 1N40xx turns on! Post as a guest Name.

Now if my logic is correct, I want to know how can I figure it’s precise model so I can change it? Sign up or log in Sign up using Google.

It may not be as simple as a year, it may mean month 5, for example. China Manufacture A4 Transistor. What is the type of this surface mount transistor?

I would appreciate if you can give me a schematic for the replacement you suggested?. Transaction area Through check Transaction Area.

Competitive price advantage helps to save your purchase cost and your precious time. Not knowing the rest of the circuit, a safe replacement would likely be a series of two 1N or BAV70 indeed paralleled by a beefier device like an 1N – this would be as good at suppressing the back EMF quickly while unloading most of the current spike into the 1N Thanks in advance and sorry for my english.

Using a multimeter I figured it’s a pnp type Negative probe to base gave me a reading in diode mode however the check was done on this other one that looks exactly the same and so I confirmed the type.

New Transistor Z A4. We have best quality controlBest Service and competitive Price. Well the problem obviously is from our power source here in Iraq we use generators along with power grid and the generators most of the time are unstable and under voltage. NO, that wasn’t my intent! Now i have to test the relay which i think will work ok.
