Amplifier Transistors(PNP Silicon)

Amplifier Transistors PNP Silicon Features • Pb−Free Packages are Available*

Damper diodes

DESCRIPTION Rugged glass package, using a high temperature alloyed construction. This package is hermetically sealed and fatigue free as coefficients of expansion of all used parts are matched. FEATURES • Glass passivated • High maximum operating temperature • Low leakage current • Excellen

PNP general purpose transistors

DESCRIPTION PNP transistor in a TO-92; SOT54 plastic package. NPN complements: JC546, JC547 and JC548. FEATURES • Low current (max. 100 mA) • Low voltage (max. 65 V). APPLICATIONS • General purpose switching and amplification.

Quad timer

DESCRIPTION The 558 Quad Timers are monolithic timing devices which can be used to produce four independent timing functions. The 558 output sinks current. These highly stable, general purpose controllers can be used in a monostable mode to produce accurate time delays; from microseconds to hours
