19、 of the isolated-mounting type thyristors, transistors, diodes, and the like, and hybrid modules consisting of combinations of these devices. 1.2 These requirements do not apply to snubber and commutation circuits associated with thyristors, transistors or other analog semiconductor devices. 1.3 The
20、se 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. 1.4 These requirements apply to isolated semiconductors for use as components in products. Co
21、mpliance 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 us
22、e under the conditions that prevail in actual service. 2 Components 2.1 Except as indicated in 2.2, a component of a product covered by this Standard shall comply with the requirements for that component. See Appendix A, for a list of standards covering components generally used in the products cove
23、red by this Standard. 2.2 A component is not required to comply with a specic requirement that: a) Involves a feature or characteristic not required in the application of the component in the product covered by this standard, or b) Is superseded by a requirement in this standard. 2.3 A component sha
