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.
gollark: It's going to be *so* Turing-complete!
gollark: Ah yes, regex-substitute some of the code, good idea.
gollark: X Æ A-12 ii or something.
gollark: § Calculate the SHA256 digest of the program as a raw bytestring. Lossily convert it to UTF-8, discarding invalid parts. Interpret the resulting string as Turi source code like i.Æ Create a new VM/container/isolated execution environment. Run the rest of the program in this environment.
gollark: Turi now has § and Æ.
