Hello friends, I would like you to get me out of a doubt. I have a transistor. The code is J599 which I don't know what it is, nor how it is proven. Look for your datasheet, but I really do not understand it. I would like you to indicate if it is a mosfep or transistor. npn or pnp or of another type since in two of its pins it gives me a measurement as if it were an npn transistor and with respect to the other na swims by nowhere

For better reference watch this video

right friend roger thank you well if it is a mosfep as it indicates to me then it is damaged because i explain it only marks me with the red tip of the tester in the center pin and the black tip to the right and gives me a measurement of 523 millivolt now I play with the black tip the left pin does not mark anything but when you put it back to the right you should have activated with a lower measurement and it does not, now there are two types of mosfep I think of n and the negative and positive p in my case would be which positive correct me if I'm wrong roger friend and thanks for helping me

if I correctly perform the entire test and not activate

thanks friend roger if it is damaged and if it is a mosfer equal to the explanation you gave me and to the video thank you

Good afternoon with the permission of all the teachers of Yoreparo .. the mosfet is better to do a dynamic test with a source of 12v so one gives an account if active and desative .. I say it x experience lived with this same mosfet .. I tested it with the tester and a half and check that he checks the TV and I did not find anything bad until he gave me the dynamic test and bingo: The mosfet does not activate anything .. In my case it is the active q 15v for main card the mosfet J599 is a mosfet channel P which I am also looking for and I do not get it anywhere :( mine is in TO-251 capsule I am from Venezuela :( .. it will be that some liner master could help me with any replacement that meets the parameters of the same ....? is for a 46-inch panasonic plasma TV model TC-P46C2 really q no longer where to look or ask anyone .. I hope you can help me

Hello friend Victor I thought that I had already closed this post but I tell you I am from Venezuela too and I struggled to get that mosfep and I did not get it and I had to try an irfz44n and it worked perfectly perfect colleague

good night friend yoelsi ... They are not the same since the J599 is a mosfet channel P and the IRFZ44N is channel N
