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.
Thanks in advance and tdansistor for my english. Transaction area Through check Transaction Area. Home Questions Tags Users Unanswered. Post as a guest Name. 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! Sign up or log in Sign up using Google.
About product and suppliers: BOM price list offer 0. Supplier Types Trade Assurance. It may not be as simple as a year, it may mean month 5, for example. I was thinking it may trnasistor diode logic to power a relay under two different conditions, but it could indeed be just flyback diodes. Since i found alot of BAS16 in an old pc motherboard i have.
You can also choose from free samples, paid samples. A4 Transistor SOT23 0. Competitive price advantage helps to save your purchase cost and your precious time. Marking reads A4t 95, as you can see, but a search on google was futile and I couldn’t reach anything so figured transistoor here may return something.

A wide variety of a4 transistor options are available to you, such as field-effect transistor, logic ics, and triode transistor. Marking which says “BAV70 – A4” and “t: Email Required, but never shown. Relevancy Tarnsistor Level Response Rate. And as of now I am pretty sure the problem is with this obviously burnt transistor that controls the compressor’s relay. I would appreciate if you can give me a schematic for the replacement you suggested?. All parts quoted are new and unused and are in original factory packaging unless specified.

I have a no frost freezer which stopped freezing efficiently and after trajsistor research and trials I found the problem to be related to control board. New Transistor Z Trasistor.

I get it that i should connect the cathods of the two 1n as one terminal. Transisor Naji 3 2. Fortunately the compressor is working ok when i connected it directly to mains. Aim to be the best reliance semiconductor supplier of china.

Now i have to test the relay which i think will work ok. 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!
We have best quality controlBest Service and competitive Price. As such, I believe it’s probably adequate mA continuous, 4A for 1 us! And the two anods will be the other pins. 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 The diodes are probably just used as freewheeling diodes for the relay coils verify the circuit before modifying anything!
Using a multimeter I figured it’s ttransistor 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.
