3.3 Noise and ESD withstand capability
3.3.1 Evaluation circuit of noise withstand capability
series have been confirmed to be with over +/-2.0kV noise withstand capability by the noise
evaluation under the conditions shown in Fig.3-3-1. However noise withstand capability greatly depends on the
test environment, the wiring patterns of control substrate, parts layout and other factors, it is recommended to
conduct enough evaluation using prototype product.
[Condition]
(1) For 1200V series; V
CC
=600V, V
D
=15V, T
a
=25°C, no load
(2) For 600V series; V
CC
=300V, V

=15V, T
a
=25°C, no load
Scheme of applying noise: From AC line (R, S, T), Period T=16ms, Pulse width tw=0.05-1
μs, input in random.
