Howdy y'all,

As the title implies, I was curious as to what the recommended torque was to secure the IPTC012N08NM5 to a heatsink? I couldn't find anything in the datasheet or any of the supplemental documentation on what the force should be. 

Thanks 

Hello,

I have an older treadmill with a faulty mosfet. Can you recommend an alternate as I can't find the original part?

Hello Team,
We are planning to use the MOSFET IPTG039N15NM5 for one of our applications.
We are using a Photovoltaic MOSFET Driver VOM1271T to drive the MOSFET.
Hence the gate to source voltage will be 8.4V.
Attached is the snippet from the schematic of the same.

Our requirements are.

• Maximum drain voltage = 48V (so the MOSFET shall have a VDS > 60V)
• Low RDSon =  as low as possible
• Gate Capacitance = as low as possible (since the output current of the VOM1271T is only 15uA, a high gate capacitance will result in high turn on time).
• Low OFF state capacitance =  The drain to source off state capacitance shall be very low else we will get high frequency signals at the output even if the MOSFET is OFF.
• Continuous Drain Current = >150A (The continuous drain current of the MOSFET is marked as 190A in the datasheet.)
  So can you please confirm whether a single MOSFET is enough to carry 150A of current.
  On our system, the 150A current may last for 5-10 Seconds.
  The continuous current will be 90A for all other time.
  What are the precautions we need to take for such a high current.
  Please confirm whether a single MOSFET is able to carry this much current?.
  
  Looking for your reply.

Hello,

IRFP044NPBF is discontinued, I found IRFP064NPBF, can I use it to replace the IRFP044NPBF ?

My project uses this mosfet as an electronic load for 20V, 3A, 60W max.

For MOSFET Loss calculation of inductive load, there are clear methods. But for resistive load, it is rare to see the calculation method.  How to calculate the switch time of MOSFET when the load is a resistor?

Hello

What will be the effect of Output capacitance Coss of Mosfet on EMI/EMC testing in DC-DC Converter.

Hi Team,

I am using the part  BSS84PH6327XTSA2 with 5V compatible microcontroller. For one of our development project we are migrating to 3.3V operating microcontroller.It is given in the datasheet, that the maximum VGS threshold is -2V.

My microcontoller can source upto 8mA and VOH value will be 2.9V. Can anyone please confirm that the MOSFET can be used at the above specified condition.I am using the FET to drive the optocoupler.

Thanks & Regards
