I was thinking it may be diode logic to power a relay under two different conditions, but it could indeed be just flyback diodes. 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 Email Required, but never shown.
All parts quoted are new and unused and are in original factory packaging unless specified. Transaction area Through check Transaction Area. Most of our products are new and original, any interests please contact me. 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!
Home Questions Tags Users Unanswered. What is the type of this surface mount transistor?
I get it that i should connect the cathods of the two 1n as one terminal. Since i found alot of BAS16 in an old pc motherboard i have. Aim to be the best reliance semiconductor supplier of china. But constantly replacing diodes while investigating another problem can get tiring. And as of now I am pretty sure the problem is with this obviously burnt transistor that controls the compressor’s relay. A4 Transistor SOT23 0. 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.
Now if my logic is correct, I want to know how can I figure it’s precise model so I can change it? But what about the 95 marking? 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. But how should i connect the 1n which I have? NO, that wasn’t my intent! A wide variety of a4 transistor options are available to you, such as field-effect transistor, logic ics, and triode transistor.

Post as a guest Name. The diodes are probably just used as freewheeling diodes for the relay coils rtansistor the circuit before modifying anything! 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.
