The CPH3105 is a PNP Epitaxial Planar Transistor manufactured by SANYO Semiconductor. It is designed for high-current switching applications.

Applications

• High-current switching circuits
• Relay driver circuits
• Lamp driver circuits
• DC-DC converters
• Power management systems

Features

• High collector current (Ic = -3A)
• Low saturation voltage (VCE(sat) = -0.5V max @ Ic = -1A)
• High hFE (hFE = 100-300 @ Ic = -1A)
• Excellent switching characteristics
• Small surface mounting type (SOT-23 package)

Benefits

• Efficient high-current switching
• Reduced power dissipation due to low saturation voltage
• Simplified circuit design due to high hFE
• Improved switching speed
• Compact design due to small package size

Additional Details

The CPH3105 has a collector-emitter voltage (VCEO) of -20V, a collector-base voltage (VCBO) of -30V, and an emitter-base voltage (VEBO) of -5V. It has a power dissipation (PC) of 1W. The operating junction temperature (Tj) ranges from -55°C to +150°C. This transistor is typically used in applications requiring efficient and compact high-current switching.

The SOT-23 package allows for high-density mounting on printed circuit boards, making it suitable for space-constrained applications. The high hFE ensures that the transistor can be easily driven by low-current control signals. The low saturation voltage minimizes power loss during switching, which increases the overall efficiency of the circuit.
