I’m trying to figure out if a MOSFET can handle a single current pulse for a given time duration, at a given VDS and at a given ambient temperature. The CSD18540Q5B for example.
I’m not sure I can just look at the SOA curve because I’m not sure if this curve only applies to devices at 25°C. How do I figure out if the device can handle the pulse (single) at 71°C?
Pulse handling requirements:
- Single Pulse (not repetitive)
- case temp = 71°C or 105°C.
- Time duration = 20ms
- Current = 4.5 Amps
- VDS = 16.5V
Thanks,
Nick
