What is the type of this surface mount transistor? – Electrical Engineering Stack Exchange

Most of our products are z4t and original, any interests please contact me. Do you test all your goods before delivery9 A: Since i found alot of BAS16 in an a4y pc motherboard i have.

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.

China Manufacture A4 Transistor. It may not be as simple as a year, it may mean month 5, for example. Wisam Naji 3 2. And the two anods will be the a4tt pins. Relevancy Transaction Level Response Rate. Now if my logic is correct, I want to know how can I figure it’s precise model so I can change it?

Transaction time Through check Transaction Time. 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. But what about the 95 marking? 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 transstor return something. We will ship the items within working days after the payment is reached. 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.

All parts quoted are new and unused and are in original factory packaging unless specified. Thanks in advance and sorry for my english. Trabsistor would appreciate if you can give me a schematic for the replacement you suggested?.

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. Aim to be the best reliance semiconductor supplier of china. You can also choose from free samples, paid samples.

About product and suppliers: But how should i connect the 1n which I have? The diodes are probably just used as freewheeling diodes for the relay coils verify the circuit before modifying anything!

What is your terms of delivery9 A: I was thinking it may be diode logic to power a relay under two q4t conditions, but it could indeed be just flyback diodes.


Email Required, but never shown.

Not knowing the rest of the circuit, a safe replacement would likely be a series of two 1N trxnsistor BAV70 indeed paralleled by a beefier device like an 1N – this would transiator as good at suppressing the back EMF quickly while unloading most of the current spike into the 1N And as of now I am pretty sure the problem is with this obviously burnt transistor that controls the compressor’s relay.

NO, that wasn’t my intent! Post as a guest Name. But constantly replacing diodes while investigating another problem can get tiring.
