Provides the requirements applicable to the following sub-categories of bipolar transistors excluding microwave transistors: a) Small signal transistors (excluding switching and microwave applications); b) Linear power transistors (excluding switching, high-frequency, and microwave applications); c) High-frequency power transistors for amplifier and oscillator applications; d) Switching transistors for high speed switching and power switching applications; and e) Resistor biased transistors.

IEC 60747-7:2010 gives the requirements applicable to the following sub-categories of bipolar transistors excluding microwave transistors.
- Small signal transistors (excluding switching and microwave applications);
- Linear power transistors (excluding switching, high-frequency, and microwave applications);
- High-frequency power transistors for amplifier and oscillator applications;
- Switching transistors for high speed switching and power switching applications;
- Resistor biased transistors. The main changes with respect to previous edition are listed below.
a) Clause 1 was amended by adding an item that should be included.
b) Clauses 3, 4, 5, 6 and 7 were amended by adding terms, definitions, suitable additions and deletions those should be included.
c) The text of the second edition was combined with that of IEC 60747-7-5.

This publication is to be read in conjunction with IEC 60747-1:2006.
