Actual values at operating temperature will exceed the value at T, = +25°C. When supply voltages are +15V, no-load operating junction temperature - without a heat sink may rise 20-30°C above ambient, and more under heavy load conditions. Accordingly, tg will change significantly during warm-up. Refer to Ip vs temperature graph for expected values, ego MAKI .
