TEXT -456 400 Left 2 ;Notes: \n Both MOSFETs dissipate about 50W for 1 second. The condition is repeated five times at a 10 second interval.\n The first MOSFET is not attached to a heat sink. The second MOSFET has a heat sink attached to the tab (case) of the TO-3P package.\n The heat sink is formed from 1000mm^3 of aluminum. The heat sink has a 10C/W dissipation to the 85C ambient environment.\n Rinterface is not specified, so the default thermal impedance of (100C/W)/Area_Contact_mm2 is used. (Simulates thermal grease or sil-pad.)\n The junction and case temperatures can be observed in the waveform viewer at the respective Tc and Tj nodes.\n If the simulation model is not found please update with the "Sync Release" command from the "Tools" menu.\n It remains the customer's responsibility to verify proper and reliable operation in the actual application.\n Component substitution and printed circuit board layout may significantly affect circuit performance or reliability.\n Contact your local sales representative for assistance. This circuit is distributed to customers only for use with LTC parts.\n Copyright <20> 2016 Linear Technology Inc. All rights reserved.
