A, 17-Aug-15 6 Document Number: 62993 For technical questions, contact: automostechsupport@vishay.com THIS DOCUMENT IS SUBJECT TO CHANGE WITHOUT NOTICE. THE PRODUCTS DESCRIBED HEREIN AND THIS DOCUMENT ARE SUBJECT TO SPECIFIC DISCLAIMERS, SET FORTH AT www.vishay.com/doc?91000 N-CHANNEL THERMAL RATINGS (TA = 25 °C, unless otherwise noted) Normalized Thermal Transient Impedance, Junction-to-Ambient Normalized Thermal Transient Impedance, Junction-to-Foot Note • The characteristics shown in the two graphs - Normalized Transient Thermal Impedance Junction-to-Ambient (25 °C) - Normalized Transient Thermal Impedance Junction-to-Case (25 °C) are given for general guidelines only to enable the user to get a “ball park” indication of part capabilities. The data are extracted from single pulse transient thermal impedance characteristics which are developed from empirical measurements. The latter is valid for the part mounted on printed circuit board - FR4, size 1" x 1" x 0.062", double sided with 2 oz. copper, 100 % on both sides. The part capabilities can widely vary depending on actual application parameters and operating conditions. 10-3 10-2 1 10 600 10-1 10-4 100 2 1 0.1 0.01 0.2 0.1 0.05 Single Pulse Duty Cycle = 0.5 Square Wave Pulse Duration (s) 1.
