f ns TJ = 25°C, IF = 104A

nC di/dt = 100A/μs

Intrinsic turn-on time is negligible (turn-on is dominated by LS+LD)

Notes:

 Repetitive rating; pulse width limited by

max. junction temperature. (See fig. 11).

‚ Starting TJ = 25°C, L = 0.08mH

RG = 25, IAS = 104A. (See Figure 12).

ƒ ISD  104A, di/dt  240A/μs, VDD V(BR)DSS,

TJ  175°C

„ Pulse width  400μs; duty cycle  2%.

… Coss eff. is a fixed capacitance that gives the same charging time

as Coss while VDS is rising from 0 to 80% VDSS .

† Limited by TJmax , see Fig.12a, 12b, 15, 16 for typical repetitive

avalanche performance.

‡ This value determined from sample failure population, starting

TJ = 25°C, L = 0.08mH, RG = 25, IAS = 104A.

ˆ Ris measured at TJ of approximately 90°C.
