The maximum operating temperature range for the IRF6894MTRPBF is -55°C to 150°C.
No, the IRF6894MTRPBF is not a radiation-hardened device. It is not designed to withstand high levels of radiation.
While the IRF6894MTRPBF is a high-performance device, it is not specifically designed for high-reliability applications. You may need to consider other devices that are specifically qualified for high-reliability use.
The recommended PCB layout for the IRF6894MTRPBF involves using a thermal pad to dissipate heat, and keeping the drain and source pins as close together as possible to minimize inductance. You should also use a low-ESR capacitor for the gate driver.
Yes, you can use multiple IRF6894MTRPBF devices in parallel to increase the current handling capability. However, you will need to ensure that the devices are properly matched and that the gate drive signals are synchronized.
