The maximum operating temperature range for the IRFI634GPBF is -55°C to 175°C.
No, the IRFI634GPBF is not a radiation-hardened device. It is not designed to withstand high levels of radiation.
While the IRFI634GPBF is a high-quality device, it is not specifically designed for high-reliability applications. Engineers should consult with Vishay Siliconix or a qualified reliability expert to determine if the device meets the required standards.
The recommended PCB layout and thermal management for the IRFI634GPBF can be found in the Vishay Siliconix application note AN608A, 'Power MOSFET Thermal Management'.
Yes, the IRFI634GPBF can be paralleled to increase current handling, but it requires careful consideration of the device's thermal and electrical characteristics. Engineers should consult with Vishay Siliconix or a qualified design expert to ensure proper paralleling and thermal management.
