Hi do you know the characteristics of this transistor? Thanks for the reply

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
I found something that says that it is a mosfet but I could not find a data sheet for itComment

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, guys!
The same 32" Philips TV I was having video issues, but now I don't have standby led at all. Someone here shared with me the schematic of the power supply, and checking the voltages, I see right after the resistor R604 I'm getting 1.6 v which is too low for enabling the Gate of the Q601 mosfet (the diagram says 4.2). On the R614 resistor I'm getting 181 V in and 117 V out, then through R603 I'm getting the same 117 V in and 59.9 V out, finally getting the latter voltage in the R604 BUT getting just 1.6 V out, which is the voltage that goes on to the Gate of the Q601... -
Philips 8200 series 65PUS8204/12 stuck at Philips Logo, it does not reboot it just stays on the logo.
It does power up when pressing the power button.
I already try the power button while plugin the plug with no result.
Also put the latest firmware autorun-TPM191E_R.001.004.100.000.upg on a MBR/FAT32 USB stick at USB port2 with no result either.
Could this be an PSU or eMMC issue ? -
Hi all,
Wife has 2 Philips hair curling irons half defective - after learning how they're supposed to work and testing them, it turned out that both have defective power cables, and both on the same place; broken wires due to wire bending.
As they were both relatively easy to disassemble, and cables are plugged not soldered (as they can rotate in the handle), I was sure it would be easy to find replacements. But - NO! I'm unable to find anything similar on ebay or Aliexpress.
Not sure if this is something Philips proprietary, or a standard, but the cable plug... -
Hi
I have here a Philips 47PFS7509/12 LCD TV which came to me with a weird problem : without signal i could access menu, make a factory reset, access menus, etc.
When i applied cable signal to check image, i had normal picture, but TV was restarting.
I downloaded original firmware and applied the update, but the problem remained.
From a colleague i received a "factory package software" which is a lot bigger.
I made another firmware update, but still did not solve the problem.
Somewhere on the way the error got worse, because at the moment the... -
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....
