Rθ is measured at TJ of approximately 90°C. Refer to AN-1086 for guidelines for measuring V(BR)CES safely. Pulse width limited by maximum junction temperature. Values influenced by parasitic L and C in measurement. When mounted on 1” square PCB (FR-4 or G-10 Material). For recommended footprint and soldering techniques refer to application note #AN-994.http://www.irf.com/technical-info/appnotes/an-994.pdf 1E-006 1E-005 0.0001 0.001 0.01 0.1 t1 , Rectangular Pulse Duration (sec) 0.001 0.01 0.1 1 0.20 0.10 D = 0.50 0.02 0.01 0.05 SINGLE PULSE ( THERMAL RESPONSE ) Notes: 1.
