Figure 1, 2, 3 and 4 specify the maximum average

output current allowable for a given ambient tem-

perature. The maximum allowable output current

and power dissipation are related by the expression

Applications Information

On-Resistance and Derating Curves

The Output On-Resistance, R

, speciﬁed in this data

(ON)

Rss=Po(max)/(Io(max)) from which Rss can be calculat-

sheet, is the resistance measured across the output

contact when a pulsed current signal (Io=120mA) is

applied to the output pins. The use of a pulsed signal (≤

30ms) 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.

ed. Staying within the safe area assures that the steady

state MOSFET junction temperature remains less than

125°C.

Turn On Time and Turn Oﬀ Time Variation

The ASSR-41xx 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 Figures 11 and 13. The changes of the turn

on and turn oﬀ time with ambient temperature are also

shown in Figures 12 and 14.
