A, November TO 4. Similar Threads There are no similar threads yet. They are from different manufacturers. I only have available IRFN units. Feb 11, 4. I’ve asked Steve for his advice. Yes, I think you’re probably right. Can I make the replacement safely?


Capacitance Characteristics Figure 6. Feb 11, 2. Hi Kris Nice to participate in the forum. 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. This advanced technology has been especially tailored to minimize on-state resistance, provide superior switching performance, and withstand high energy pulse in the avalanche and commutation mode.

My initial thoughts are that it is an entirely suitable replacement but its hard to compare them on a mobile device.

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. Feb 11, 1. Preliminary First Production This datasheet contains preliminary data, and supplementary data will be published at a later date.

Specifications may change in any manner without notice. Hi Jorge and welcome to Electronics Irc640b What brand are the existing devices? Feb 11, 3.
