BC558 - PNP 30V 200mA

BC558 is a widely used silicon epitaxial PNP bipolar junction transistor (BJT) primarily designed for low-power switching and small-signal amplification. It is commonly found in TO-92 plastic packaging and is the complementary pair to the NPN BC548 transistor. 

Technical Specifications

The BC558 is rated for the following standard operating conditions:

• Transistor Type: PNP.
• Collector-Emitter Voltage (VCEO): -30V (maximum).
• Continuous Collector Current (IC): -100mA.
• DC Current Gain (hFE): Ranges from 110 to 800, depending on the specific grade (A, B, or C).
• Power Dissipation (Ptot): Typically 500mW to 625mW depending on the manufacturer.
• Transition Frequency (fT): Up to 150MHz.
