Re: transistor ON 724 PHILIPS
The title is wrong, the marking is:ON 724
I apologize for the mistake -
Re: transistor ON 724 PHILIPS
What is it used in? Make , Model, maybe you have a schematic? I see this is not a picture of your componentLast edited by R_J; 11-12-2022, 06:50 PM.Comment

Re: transistor ON 724 PHILIPS
maybe email philips and ask them for a datasheetComment

Re: transistor ON 724 PHILIPS
I found nothing on ON724 Philips transistor, it must be a house number as Philips power transistors are usually prefixed BU, BUS, BUZ etc.
Did see same "date code" on a BUS14A. OP's pic looks like a clone from aliexpress but store 15814935579 does not exist.
BUY72-4 has "724" as vert. defl. tranny.Comment

Re: transistor ON 724 PHILIPS
Thank you for your prompt replies. The ON724 is mounted in an old oil burner control board that works well. Unfortunately, I no longer have that board. I'll see if I can post a photo. I just wanted to know the features of this component not having found the datasheet. The electronics of this card are very dated. In addition to the ON724 there is another transistor but in a TO5 container that starts with ON but I don't remember the rest of the initials.
I found this link on the net

Re: transistor ON 724 PHILIPS
I agree, it is likely a custom/in house number for the company that made the controllerComment

Re: transistor ON 724 PHILIPS
For an oil burner controller, the only specialty power transistor that I can think of would be for the igniter. In the mid-80's a high voltage Darlington was used like old MJ10012, BU941ZPFI
The ones with built-in clamp zener are best for when the spark gap gets too big, the transistor is protected.
Unless the burner board uses CDI HV inverter or mains for the ignition?
The fuel solenoid valve does not need that much current.Comment

Hello
Got this speaker from a friend , defective. Power led comes on and off , in a loop.
Disassembled, got the board out, and after a bit of measuring I found a low resistance on a 5v6 line. With a bit of current I found a transistor heating up on that line (labeled T1 and 113 as on pic).
After removing this guy, I got a value of 0.7 in diode mode on that 5v6 line, which before had 0.02 or something like that.
I tested powering it up without the IC, and the speaker turns on and stays on, and works fine
Still, I need to replace this transistor.... -
Hello,
I've got a really strange issue with the speakers on my Philips 43PUS7506/12. It makes this awful loud buzzing now. It happened after it was attempted to be wall mounted - I think the back got squeezed and something broke.
I thought maybe the speakers got damaged, so I replaced them - no dice.- Using the internal speakers, it always happens.
- Using the headphone jack, it never happens.
- Using the digital/optical out with a soundbar - it happens after about 2h/movie runtime - it's never as drastic, it just pops in and out, but I didn't want it to damage the sound bar

hi people, i need some help to identify a transistor(q14) that is missing on the board, so the gpu has no voltage i think that q14 activate the phases for gpu, but i dont have schematic or boardview, but i think its the same transistor than q15 and q16, thanks... -
Hello everyone,
I guess I need help from the masters to try and find what is frying a 2SC5669 transistor on the left channel of this front center Amp for a NAD T752.
Was working perfectly and all of a sudden I heard a pop, and then a glow from the amp. Not only did the 2SC5669 burn a leg, but R520 which is a 220 ohm resistor partially burned - it now measures 110 ohms.
I bought this amp second hand fairly cheap as it was not working, it went into protection mode. I finally traced it down to the same transistor Q510, the one that just popped. It was shorted... -
hello there,
xbox series x hdmi u82 transistor 5 pin,
can anybody tell me voltages of this transistor in standby and power on mode ???
on which pin of this transistor are the voltages ?
