IRF7484TRPBF - International Rectifier

HEXFET® Power MOSFET

This Stripe Planar design of HEXFET® Power

MOSFETs utilizes the latest processing techniques to

achieve extremely low on-resistance per silicon area.

Additional features of this HEXFET power MOSFET

are a 150°C junction operating temperature, fast

switching speed and improved repetitive avalanche

rating. These benefits combine to make this design an

extremely efficient and reliable device for use in a wide

variety of applications.

Notes on Repetitive Avalanche Curves , Figures 15, 16:

(For further info, see AN-1005 at www.irf.com)

1. Avalanche failures assumption:

Purely a thermal phenomenon and failure occurs at a

temperature far in excess of Tjmax. This is validated for

every part type.

2. Safe operation in Avalanche is allowed as long asTjmax is

not exceeded.

3. Equation below based on circuit and waveforms shown in

Figures 12a, 12b.

4. PD (ave) = Average power dissipation per single

avalanche pulse.

5. BV = Rated breakdown voltage (1.3 factor accounts for

voltage increase during avalanche).

6. Iav = Allowable avalanche current.

7. ∆T = Allowable rise in junction temperature, not to exceed

Tjmax (assumed as 25°C in Figure 15, 16).

tav = Average time in avalanche.

D = Duty cycle in avalanche = tav ·f

ZthJC(D, tav) = Transient thermal resistance, see figure 11)

PD (ave) = 1/2 ( 1.3·BV·Iav) = DT/ ZthJC

Iav = 2DT/ [1.3·BV·Zth]

EAS (AR) = PD (ave)·tav
