LOAD
Input and output polarity must be observed.
Inductive loads must be diode suppressed.
Transient Protection
All loads are inductive, even ones that are not so labeled. An
inductive load will produce harmful transient voltages when it
is turned off. The more perfect the switch, the larger the tran-
sient voltages; the IGBT output is so nearly an ideal switch
that the transient voltages produced by seemingly "non-induc-
tive" loads can cause damage if not suppressed. Diodes should
be fast recovery type with PIV rated greater than supply voltage.
