HEXFET® Power MOSFET

This Advanced Planar Stripe HEXFET ® Power MOSFET utilizes

the latest processing techniques to achieve extremely low on-

resistance per silicon area. Additional features of this HEXFET

power MOSFET are a 175°C junction operating temperature, low

RθJC, fast switching speed and improved repetitive avalanche

rating. This combination makes the design an extremely efficient

and reliable choice for use in a wide variety of applications.

(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]
