Maximum current is calculated as: R M DS(ON) where P OS D is maximum power dissipation at TC = 25°C and RDS(on) is at TJ(max) and VGS = 10V. Package current limitation is 21A 4. BV(avalanche) Single-Pulse rating is guaranteed if device is operated within the UIS SOA boundary of the device. FET FDD6637 Rev. C(W) www.fairchildsemi.com
