BC557 PNP transistor

BC557 PNP transistor

70.00

The BC557 is a general-purpose PNP bipolar junction transistor (BJT) commonly used in amplification and switching applications. It is designed for low to medium power applications where moderate switching speeds and good amplification performance are required. The BC557 transistor comes in a TO-92 package, which is compact and suitable for through-hole PCB mounting.

Key Features:

  • Transistor Type: PNP (Positive-Negative-Positive).
  • Package Type: TO-92, a widely used package for small-signal transistors.
  • Voltage Ratings:
    • Collector-Emitter Voltage (VCEO): -45V
    • Collector-Base Voltage (VCBO): -50V
    • Emitter-Base Voltage (VEBO): -5V
  • Current Ratings:
    • Continuous Collector Current (IC): -100mA
    • Peak Collector Current (ICM): -200mA
  • Gain (hFE): Typically 125 to 800 at IC = -2mA, VCE = -5V.
  • Frequency Response: Up to several hundred megahertz (MHz) depending on the circuit configuration.
  • Applications: Commonly used in audio amplifiers, signal processing circuits, voltage regulators, and other general-purpose switching applications.

Technical Specifications:

  • Package: TO-92.
