25、ldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in addition to other

26、activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested in the sub

27、ject dealt with may participate in this preparatory work. International, governmental and non-governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions de

28、termined by agreement between the two organizations. 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested IEC National Com

29、mittees. 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC cannot be held responsible for the way in whi

30、ch they are used or for any misinterpretation by any end user. 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent possible in their national and regional publications. Any divergence between any IEC Publica

31、tion and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any equipment declared to be in conformity with an IEC Publication. 6) All users should ensure th

32、at they have the latest edition of this publication. 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of its technical committees and IEC National Committees for any personal injury, property damage or other damage of any na

33、ture whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications. 8) Attention is drawn to the Normative references cited in this publication. Use of the referenc

34、ed publications is indispensable for the correct application of this publication. 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. Internati

42、Scope This part of IEC 60747 gives details for the following categories of metal-oxide semiconductor field-effect transistors (MOSFETs) with inverse diodes. Type B depletion (normally on) type. Type C enhancement (normally off) type. NOTE 1 MOSFETs for some applications may not have inverse diode ch

43、aracteristics in the data sheet. Special circuit element structures to eliminate body diode are under development for such applications. MOSFET applications such as motor control equipment need to specify the inverse diode characteristics in the MOSFET to use the inverse diode as a free wheeling dio

44、de. NOTE 2 MOSFET is classified as a kind of insulated gate field-effect transistor (IGFET) in IEC 60747-8. NOTE 3 The graphical symbol only for type C is used in this standard. It equally applies for the measurement of type B devices. 2 Normative references The following referenced documents are in
