Introduction :

S8550M 是一顆極為通用的 PNP 型雙極性電晶體(BJT),專門設計用於中功率放大電路與電子開關切換(例如:驅動小馬達、蜂鳴器、繼電器或 LED 燈線)。
它是大名鼎鼎的直插式三極體 S8550(TO-92 封裝)的 SMD(表面貼裝)小體積升級版本,並常與 NPN 型的 S8050M 組成經典的互補推挽對管(Push-Pull Pair)。

規格與特性概要

• 電晶體極性:PNP
• 集極-射極電壓((V_{CEO})):-25 V(代表它最高可承受 25V 的工作電壓)
• 集極電流((I_{C})):-800 mA(部分大廠加強版如藍箭電子可達 -1.5A,具備優秀的大電流驅動能力)
• 耗散功率((P_{C})):450 mW
• 直流電流增益((h_{FE}) 放大倍數):約 85 ~ 300 之間
• 特徵頻率((f_{T})):100 MHz ~ 150 MHz
