Single Pulse 10 o 1. A critical component is any component of a life support device or system whose failure to perform can be reasonably expected to cause the failure of the life support device or system, or to affect its safety or effectiveness.

Hi Kris Nice to participate in the forum. After that, you can post your question and our members will help you out. Feb 13, 8. I will do some more thorough investigations later in the day. Life support devices or systems are devices or systems which, a are intended for surgical implant into the body, or b support or sustain life, or c whose failure to perform datxsheet properly used in accordance with instructions for use provided in the labeling, can be reasonably expected to result in significant injury to the user.


N-channel V – 0. My initial thoughts are that it is an entirely suitable replacement but its hard to compare them on a mobile device.

Feb 11, 3. This advanced technology has been especially tailored to minimize on-state resistance, datasyeet superior switching performance, and withstand high energy pulse in the avalanche and commutation mode.

Feb 11, 1. Similar Threads There are no similar threads yet. Feb 11, 5. Ask a Question Want to reply to this thread or ask your own question? The datasheet is printed for reference information only.

Feb 13, 9. Feb 11, 4. As long as the device is not required to operate in avalanche mode at energies near the single pule limit I would have no hesitation in swapping the IRF for an IRFN. Specifications may change in any manner without notice.

Pulse width limited by maximum junction temperature 2. Is there a manufacturer’s logo? Documents Flashcards Grammar checker. Capacitance Characteristics Figure 6.


Can I make the replacement safely? Preliminary First Production This datasheet contains preliminary data, and supplementary data will be published at a later date. They are from different manufacturers.

On-Region Characteristics Figure 2. Fairchild Semiconductor reserves the right to make changes at any time without notice in order to improve design. Yes, I think you’re probably right. Hi Jorge and welcome to Electronics Point What brand are the existing devices? Obsolete Not In Production This datasheet contains specifications on a product that has been discontinued by Fairchild semiconductor.

Both Mosfets are International Rectifier. I only have available IRFN units. I’ve asked Steve for his advice. You’ll need to choose a username for the site, which only take a couple of moments here.
