Applications Information

allowable for a given ambient temperature. The maximum

allowable output current and power dissipation are related

On-Resistance and Derating Curves

by the expression Rss = Po(max)/(Io(max)) from which Rss

can be calculated. Staying within the safe area ensures that

the steady-state MOSFET junction temperature remains

less than 125°C.

The Output On-Resistance, R

sheet, is the resistance measured across the output contact

when a pulsed current signal (I = 1A) is applied to the

, specified in this data

(ON)

output pins. The use of a pulsed signal (≤30 ms) implies that

each junction temperature is equal to the ambient and case

temperatures. The steady-state resistance, Rss, on the

other hand, is the value of the resistance measured across

the output contact when a DC current signal is applied to the

output pins for a duration sufficient to reach thermal

equilibrium. Rss includes the effects of the temperature rise

in the device.

Turn On Time and Turn Off Time

Variation

The ASSR-15xx Series exhibits a very fast turn on and turn

off time. Both the turn on and turn off time can be adjusted

by choosing proper forward current as depicted in Figure 12

and Figure 14. The changes of the turn on and turn off time

with ambient temperature are also shown in Figure 13 and

Figure 15.

Derating curves are shown in Figure 1, Figure 2, Figure 3,
