Notes
1. The waveforms of the applied transients shall be in accordance with
“ISO 7637 part 1”,
test pulses 1, 2, 3a and 3b,
(see Fig.6).
2. In accordance with
“IEC 747-1”.
An alternative definition of T

is: T
j
= T
amb
+ P
×
R
th(j-a)
, where R
th(j-a)
is a fixed value
to be used for the calculation of T
j
. The rating for T
j
limits the allowable combinations of power dissipation (P) and
ambient temperature (T
amb
).
3. Human body model; C = 100 pF R = 1.5 kΩ.
4. Machine model; C = 200 pF R = 25
Ω.
