An external voltage has to be applied. 13. Thermal limitations of the device might derate usable current range. Table 3. Static Electrical Characteristics(continued) Characteristics noted under conditions 30 V ≤ V PWR ≤ 60 V, - 40°C ≤ T A ≤ 85°C, VIN = 0 V unless otherwise noted. Typical values noted reflect the approximate parameter means at TA = 25°C under nominal conditions unless otherwise noted. Characteristic Symbol Min Typ Max Unit |
