Pentode transistor
A pentode transistor is any transistor having five active terminals.
Early pentode transistors
One early pentode transistor was developed in the early 1950s as an improvement over the point-contact transistor.
- A point-contact transistor having three emitters. It became obsolete in the middle 1950s.
Pentode field-effect transistors having 3 gates, similar to vacuum tube pentodes have also been described[1]
Modern pentode transistors
- Triple emitter transistor in three input transistor-transistor logic gates.
- Triple collector transistor in three output integrated injection logic gates.
- Field effect transistor having three gates.
