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

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.
