Notes: Repetitive rating; pulse width limited by max. junction temperature. Starting TJ = 25°C, Q1: L = 0.13mH, RG = 50, IAS = 25A; Q2: L = 1.24mH, RG = 50, IAS = 25A. Pulse width ≤ 400µs; duty cycle ≤ 2%. R is measured at TJ approximately 90°C. When mounted on 1 inch square PCB (FR-4). Please refer to AN-994 for more details: http://www.irf.com/technical-info/appnotes/an-994.pdf Calculated continuous current based on maximum allowable junction temperature. Current is limited to Q1 = 25A & Q2 = 25A by source bonding technology. Pulsed drain current is limited to 100A by source bonding technology. IR WORLD HEADQUARTERS: 101 N.
