- 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.
