junction temperature. (See Fig. 11)
‚ Starting TJ = 25°C, L = 40mH, RG = 25Ω,IAS = 3.0A.
(See Figure 13).
ƒ ISD = 6.0A, di/dt ≤ 416A/μs, VDDV(BR)DSS,TJ ≤ 150°C.
„ Pulse width ≤ 300μs; duty cycle ≤ 2%.
Notes:
… Coss eff. is a fixed capacitance that gives the same charging timeas
Coss while VDS is rising from 0 to 80% VDSS. Coss eff.(ER) is a fixed
capacitance that stores the same energy as Coss while VDS is rising
from 0 to 80% VDSS.
† Rθ is measured at TJ approximately 90°C
‡ When mounted on 1" square PCB (FR-4 or G-10 Material). For
recommended footprint and soldering techniquea refer to applocation
note # AN- 994 echniques refer to application note #AN-994.
