Phototransistor

Japanese: phototransistor
Phototransistor

...A pin-type photodiode, which has a junction structure with an intrinsic semiconductor region sandwiched between p and n regions, can be reverse-biased by an external power source and operated at high speeds to be used in optical communications, etc.
[Phototransistor]
A two-terminal element with an n-p-n (p-n-p) junction, in which carriers excited by light act in the same way as injecting base current, and an amplified current flows when an external power source is connected. It has high sensitivity but poor linearity.

Japanese:

…p,n領域に固有半導体領域をはさんだ接合構造をもつpin形フォトダイオードは外部電源により逆バイアスをかけ,さらに高速動作にして光通信などに使用される。
[フォトトランジスターphototransistor]
 n‐p‐n(p‐n‐p)接合をもつ2端子素子で,光により励起されたキャリアがベース電流を注入したのと同じ作用をし,外部電源をつなぐと増幅された電流が流れる。高感度であるが直線性は劣る。…
