These requirements apply to semiconductor devices of the
isolated-mounting type – thyristors, transistors, diodes, and the
like, and hybrid modules consisting of combinations of these
These requirements do not apply to snubber and commutation
circuits associated with thyristors, transistors or other analog
These requirements cover the isolation performance of
thyristors, transistors, diodes, and the like, and their
combination in module packages and constructional features that are
pertinent to that performance.
These requirements apply to isolated semiconductors for use as
components in products. Compliance of an isolated semiconductor
with these requirements does not determine that the semiconductor
is acceptable for use as a component of an end product without
further investigation. The acceptability of a semiconductor in any
particular product depends upon its acceptability for continued use
under the conditions that prevail in actual service.
