Semiconductor devices - Part 5-5: Optoelectronic devices - Photocouplers
IEC 60747-5-5:2020 specifies the terminology, essential ratings, characteristics, safety tests, as well as the measuring methods for photocouplers.
Note: The term "optocoupler" can also be used instead of "photocoupler".
This edition includes the following significant technical changes with respect to the previous edition:
a) optional data sheet basic insulation rating in accordance with IEC 60664-1:2007, 6.1.3.5;
b) editorial corrections on the use of VIORM;
c) editorial corrections on Figure 2: Time intervals for method b);
d) addition of an alternative surge pulse VIOSM test method.
