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_j 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.
THERMAL CHARACTERISTICS
According to IEC 747-1.
