Zener diodes

For hobby use, pre-filled assortment boxes are a good choice. These typically contain 10–20 pieces of each voltage rating within one power class (0.5W to 1.3W). For those who need fewer, here are some recommended standard use cases:

Suppressor diodes

Suppressor diodes are essentially Zener diodes with high pulse power in a small package. They are available for low and high voltage applications (e.g. mains voltage), where they can sometimes replace varistors for voltage limiting.

Comparators

Comparators are significantly faster than op-amps. They should always be used only as comparators and not as linear amplifiers.
