R_G = 25Ω, I_AS = 44A, V_GS =10V. Part not recommended for use
above this value .
ƒ I_SD ≤ 44A, di/dt ≤ 760A/µs, V_DD ≤ V_(BR)DSS, T_J ≤ 175°C.
„ Pulse width ≤ 400µs; duty cycle ≤ 2%.
… C_oss eff. (TR) is a fixed capacitance that gives the same charging time
as C_oss while V_DS is rising from 0 to 80% V_DSS.
† C_oss eff. (ER) is a fixed capacitance that gives the same energy as
C_oss while V_DS is rising from 0 to 80% V_DSS.
‡ When mounted on 1" square PCB (FR-4 or G-10 Material). For recom
mended footprint and soldering techniques refer to application note #AN-994.
ˆ R_θ is measured at T_J approximately 90°C
‰ R_θJC value shown is at time zero
