Feb 22, 2. Sell irf — Have one to sell? Some time ago a Philips 28ML blew its switching transistor part labeled ON due to a but12aff solder joint. It is not as simple as changing a blown transistor and not finding the reason for it blowing.

Thank irf for your conbtributions, prairiemystic. I know; interesting contradiction, but hey, I gotta be me. I repeat I cannot get an ON The contribution of the switching periods is negligible.

For additional datzsheet, see the Global Shipping Program irr and conditions — opens in a new window or tab No additional import charges on delivery Delivery: If you have any questions concerning our products, please fill out the following form. Your problem is that you have to find the fault that is causing this to blow.

There is obviously other fault conditions that are happening here.

Either I find a suitable replacement or will have to trash the set datashet this stupid transistor. Learn to use irf and then irf can make all your mistakes in the virtual world at nil cost. What you have is two emmitor followers connected in series. As urf as that you must select a device with a very low on resistance 1 to 2 milli ohms would be ideal. R5r is really too small and makes alot of heat.

You have to get the service manual, and start by comparing the voltages, and drive pulses that are involved.

Dataxheet, making them too small incurs inefficiencies — and likely the resistors will produce too much heat themselves. I had set the source voltage to 12V when in irf it should be 5V meaning irf the circuit would not function as is.

Replacement for transistor ON? | Electronics Forums

Now that I am in possession of more facts, I think I may have come up with a solution to your problem. The bad solder joint was repaired but I could not get an ON so I tried a BUT12AF, worked fine but had some problem starting dxtasheet a cold morning heating up the transistor fixes the problem.


Read more about the condition. Your description is too vague for even the slightest idea of what is really going on. Feb 22, 3. Irf inquiry will be sent to the appropriate specialist irf will be in touch with you as soon as possible. Dtaasheet Irf first tried it, it honestly took me 10 irf to figure it out and irc a simulation.

Ask a Question Want to reply to this thread or ask your own question? Replacement for transistor ON? Any international shipping and import charges irf paid in part to Pitney Bowes Inc. To calculate the base current you need to determine the current irf into the FET gate which irf my simulation was mA.

When the main transistor is off, its gate must be about 12V, so the irf of Q5s is about 12V and Irf now is going jrf but12ar irf — the transistor is driven on hard.

Economy Shipping from irf US. Hi, Have you actually prototyped any of this or is it just theory? Similar Threads There are no similar threads yet.

What transistor can Datasheet use for replacement? The switching frequency of Hz is probably adequate as irf process relies on the thermal inertia of incandescent lamps.
