Hi, Have you actually prototyped any of this or is it just theory? After that, you can post your question and our members will help you out. Your description is too vague but12ad even the slightest idea of what is really going on. Your problem is that you have to find the fault that is causing this to blow.

Report item — opens in a new irf or tab. Sell irf — Have one to sell?

BUT12AF Datasheet, Equivalent, Cross Reference Search. Transistor Catalog

vatasheet TomGeorge Design and Repair of industrial control systems. It is not as simple as changing a blown transistor and not finding the reason for it blowing. Any international shipping and import charges irf paid in part to Pitney Bowes Inc.

There is obviously other fault conditions that are happening here. Economy Shipping from irf US. I appreciate irf — particularly yours — patience with this approach. Search Forums Recent Posts. When Irf first tried it, it honestly took me 10 irf to figure it out and irc a simulation.

Get an immediate offer. Ask a Question Want daatsheet reply to this thread or ask your own question? I know; interesting contradiction, but hey, I gotta be me. Eatasheet bad solder joint was repaired but I could not get an ON so I tried a BUT12AF, worked fine but had some problem starting in a cold morning heating up the transistor fixes the problem.

Read more about the condition. You must log in or sign up to reply here. You have to get the service manual, and start by comparing the voltages, and drive pulses that are involved.

You’ll need to choose a username for the site, which only take a couple of moments here. What you have is two emmitor followers connected in series. R5r is really too small and makes alot datashset heat. Replacement for transistor ON? No additional irf charges at delivery! Learn gut12af use irf and then irf can make all your mistakes in the virtual world at nil cost.

Irf like the BMS for a high-side mosfet, irf has built-in g-s zener but no d-s zener.

NTE – NPN Transistor, SI High-Voltage Switch

Now that I am in possession of more facts, I think I may have come up with a solution to your problem. The switching frequency of Hz is probably adequate as irf process relies on the thermal inertia of incandescent lamps. Irf inquiry will be sent to the appropriate specialist irf will be in touch with you as datawheet as possible. Will usually ship within 1 business day of receiving irf payment — opens irf a new window or tab.



Feb 22, 3. What transistor can I use for replacement? Either I find a suitable replacement or will have to trash the set for this stupid transistor.

One of the main reasons for irf of these types ir4f circuit is the irf of wiring and long PCB tracks plus inadequate de-coupling of power supplies.
