Webtemperature as shown in below, 2.2. Level 2 model The Level 2 model has two additional pins. They are the Tc terminal (case temperature) and Tj terminal (junction temperature). The Level 2 symbol with a source sense terminal is shown in Fig. 2. Fig. 2. Level 2 model symbol with SS terminal The thermal model inside the device model is Cauer ... WebSince Rth (j-a) is 250 deg./W, the junction temperature rises by 25 deg. per each increment of 0.1W of current consumption. This means, the junction temperature becomes 150 deg. when the current consumption is 0.5W, and the graph in this case suggests that the current beyond 0.5W can not be applied to TR.

WebIo : Rated ripple current at maximum operating temperature I : Actual ripple current 2. Ambient Temperature Calculation Formula If measuring ambient temperature (Ta) is difficult, Ta can be calculated from surface temperature of the capacitor as follows. Tj Ta Tc = − Ta : Calculated ambient Temperature Tc : Surface Temperature of capacitor WebT j(max): Junction temperature in Absolute Maximum Ratings P C: Collector power dissipation in Absolute Maximum Ratings. Junction temperature is calculated by using the above thermal resistance. ΔT j [deg.C]＝ R th(j-a) [deg.C/W] × P LOSS [W] T j = ΔT j + T a ΔT j: Junction temperature rise R th(j-a): Thermal resistance, junction to ambient

WebTa is the best operating temperature limit of the power supply, and Tc indicates the highest temperature of the entire drive. For example, Ta = 50 degrees, meaning that life is the highest when working in an environment within 50 degrees. Every 10 degrees above, life is reduced by half.
