But constantly replacing diodes while investigating another problem can get tiring. Sample Order Free samples Paid samples.

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. And as of now I am pretty sure the problem is with this obviously burnt transistor that controls the compressor’s relay. It looks like the flyback diode thats used to suppress inductive kickback when the coil is switched.

Marking which says “BAV70 – A4” and “t: Googling “SOT transistor A4t” yields http: It may not be as simple as a year, it may mean month 5, for example.

And the two anods will be the other pins. Competitive price advantage helps to save your purchase cost and your precious time. Sign up or log in Sign up using Google. Home Questions Tags Users Unanswered. Supplier Types Trade Assurance. What is the type of this surface mount transistor? All parts quoted are new and unused and are in original factory packaging unless specified.

We will ship the items within working days after the payment is yransistor. Relevancy Transaction Level Response Rate.


Do you test all your goods before delivery9 A: I reached this but was not sure if it is the same. I get it that i should connect the cathods of the two 1n as one terminal. What’s your advantage9 A: Wisam Naji 3 2. I would appreciate if you can give me a schematic for the replacement you suggested?. Transaction time Through check Transaction Time.

You can z4t choose from free samples, paid samples. The burnt one did not give me overload when I touched either probes to base however it gave me a much lower reading for probably B-C, I couldn’t confirm C-E pins than it read for B-E.

The relay use 24 vdc and if the voltage across the coil keeps fluctuating around 24 then maybe this what you mean by actuating the coil more frequently and could have burnt the diode. There are a4 transistor suppliers, mainly located in Asia. Transisfor Manufacture A4 Transistor. Post as a guest Name. What is your terms of delivery9 A: A4 Transistor SOT23 0.

Since i found alot of BAS16 in an old pc motherboard i have. A wide variety of a4 transistor transitsor are available to you, such as field-effect transistor, logic ics, and triode transistor.

Marking reads A4t 95, as you can see, but a search on google was futile and I couldn’t reach anything so figured asking here may return something. I suggesting putting the two smaller, faster diodes in series so they have a higher turn on voltage than the slower 1N or 1N parallel to them – so they will only take the back EMF until the 1N40xx turns on! Fortunately the compressor is working ok when i connected it directly to mains. You can ensure product safety by selecting from certified suppliers, including 11 with Other, 4 with ISO, and 3 with ISO certification.

Sign up using Email and Password. 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 Gold Plus Supplier The supplier supports Trade Assurance — A free service that protects your orders from payment to delivery.

NO, that wasn’t my intent! 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. Transaction area Through check Transaction Area.

Thanks in advance and sorry for my english.

Most of our products are new and original, any interests please contact me. The diodes are probably just used as freewheeling diodes for the relay coils verify the circuit before modifying anything! As such, I believe it’s probably adequate mA continuous, 4A for 1 us! Now i have to test the relay which i think will work ok.

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.
