适用范围:1.1 This standard applies to monocrystalline semiconductor rectifier cells and stacks having a rated output per cell of 10 W and above, used in power diodes for supplying dc power from ac sources at frequencies up to 2 000 c/s and voltages not exceeding 5 000 V.1.2 In so far as it is applicable, this standard relates also to controlled semiconductor devices having trigger characteristics. More detailed treatment of controlled semiconductor devices ( that is, thyristors ) would be dealt with in a separate standard.1.3 This standard does not apply to telecommunication rectifiers other than those for power supplied to such apparatus, nor to rectifiers used as auxi-liaries to measuring instruments. Further, it does not include the mains transformer or other associated transformers and apparatus, nor does it apply to rectifiers based on polycrystalline semiconductor materials.
