    Hello guys,

    i want to find the alternative transistor of kse13005-2. The datasheet. Need suggestions.

    Thank you in advance.

    The ST13005 is a NPN 400V 4A TO-220
    The STX13005 is a NPN 400V 3A TO92
    The STT13005 is a NPN 400V 2A SOT-32

    Can also use phe 13005.
    Thank you

    CDL13005,TO-220
    VCEO Collector-Emitter Voltage : 400V/4A/75W
    http://www.datasheetcatalog.org/datasheets2/71/71012_1.pdf

    MJE13005,TO-220

    KSE13005-2 means that we are getting 2amps at output.

    Thank you

    florescent emergence light circuit. in that circuit two transistor of kse13005-2 is used.

    Did you measure the total current consumption of the emergency light circuit? (2A max or less)

    In the real application circuit, the 4A component used in a 2A max current consumption is not appropriate, at least have to provide 3 times or more of 2A, it means the 2A max circuit load need a component which can provide a 6A max or more.

    Like as 2N3055 had 15A max rating, almost used it about 2~3A max in the circuit, some people maybe use it about 5A max, but it need bigger heatsink.

    Consider your original size and heat problem, if you can use Mje3055 is better than the other 4A Power components.

    Mje3055 and Mje2955 datasheet, TO220 60V/10A.

    i Do not measure the current because i purchased it from the market. after that due to high and low voltage it is damage and i did not open it. Now i open it and want to repair it so it can work again.

    Listen to ScottWang...
    You can fix it now and fix it again later when it does the same thing.... Or you can fix it using his suggestion and never have to fix it again...
    ..
    Your choice...

    At i find the transistor PHE-13005, but i am afraid to on the circuit. I am also posting the picture of old transistor and NEW transistor.

    If you use PHE-13005 to replace KSE13005, it may work fine, and you can wait to see how long it will keep it OK.
    Btw: I didn't see your device and the circuit, so I'm not sure if you use like 2N3055 is better or not, it depends on how is the power of KSE13005.

    You said it is used in emergency lighting system, so I guess the circuit is battery powered and some detection circuits to see that the AC mains is NOT there in order to start your 13005 circuit to light the fluorescence lamps. And normally the battery is put on charge when the mains is okay..

    Is that how your circuit works?

    Another way is: If the circuit is fed directly with 240V x 1.414 (after retification), then that's why your transistor gets toasted if the mains is up and down all the time. If you show us a picture of your circuit board, may be we can recommend a better solution for you..

    Did you check the components around the 13005 (HF transformer, capacitors, diodes etc) and see if any one of them is bad? How about the other 13005? Normally in a push-pull circuit, both transistors are gone at the same time...:D

    I also posted the picture of transistor of E13005-2, again i am posting.

    I check all the components in the circuit the rectifier diodes are toasted and capacitor and the transistor. I have replace the other component and stack with transistor. Because i could not found in the market.

    The circuit us fed directly i have check it by giving the main AC to the emergence light but their is not voltage on the battery.

    I am also posting the image of PCB of emergence light, If that will help. I will take more picture if you guys say.

    Regards

    If the old one E13005-2 didn't add the heatsink, then you can add a small heatsink for the new one PHE13005, it will give you a little help for the temperature of PHE13005.

    Check all the components that are circled especially the zener diodes. Make sure that they are not shorted or opened. If the zener voltage is printed on the body, try to verify them.

    Adding heatsinks is a good idea too. If the space doesn't allow a regular one, a small piece of alluminium 1/2" by 3/4" would help too.

    Are you able to get J13009? I just ordered 10 pieces from Farnell for repairing the SMPS that my friend asked me to repair.

    I do not understand the difference between the two transistor, Especially the E13005-2. I could not Found the datasheet of E13005-2 either:(.
