We do not have a fixed safe operation graph for our RF devices. Rather, we have a set on max ratings that can never be exceeded.
From the dada sheet, page 2, table 1, here is the list of max ratings for that part.
Drain--Source Voltage VDSS -0.5, +65 Vdc
Gate--Source Voltage VGS -6.0, +10 Vdc
Operating Voltage VDD 32, +0 Vdc
Storage Temperature Range Tstg -65 to +150°C
Case Operating Temperature Range TC -40 to +150°C
Operating Junction Temperature Range TJ -40 to +225°C
CW Operation @ TC = 25°C when DC current is fed through drain lead, pin 5 CW 161W 1,7 W/°C
Derate above 25°C
CW Operation @ TC = 25°C when DC current is fed through pin 4 and pin 6 CW 104W 0,41W/°C
Derate above 25°C
The junction temperate is calculated using the thermal resistance rating of the part, the operating condition and the flange temperature, which is controlled by the customer.
