BS IEC 60747-4:2007+A1:2017

This standard BS IEC 60747-4:2007+A1:2017 Semiconductor devices. Discrete devices is classified in these ICS categories:

• 31.080.10 Diodes
• 31.080.30 Transistors

This part of IEC 60747 gives requirements for the following categories of discrete devices:

• variable capacitance diodes and snap-off diodes (for tuning, up-converter or harmonic multiplication, switching, limiting, phased shift, parametric amplification);

• mixer diodes and detector diodes;

• avalanche diodes (for direct harmonic generation, amplification);

• gunn diodes (for direct harmonic generation);

• bipolar transistors (for amplification, oscillation);

• field-effect transistors (for amplification, oscillation).
