The 2SC5772 is a silicon NPN epitaxial planar transistor manufactured by Hitachi. It is designed for use in low-noise amplifier applications, particularly in VHF and UHF bands. It's well-suited for applications where a high gain and low noise figure are required.

Applications:

• Low-Noise Amplifiers (LNAs)
• VHF/UHF Receivers
• TV Tuners
• Satellite Receivers
• Communication Equipment

Features:

• NPN polarity
• High gain
• Low noise figure
• High transition frequency (fT)
• Small package size

Benefits:

• Improved signal reception due to low noise amplification.
• Enhanced sensitivity in communication systems.
• Higher gain for weak signals.
• Reduced interference and distortion.
• Compact design for space-constrained applications.

Specifications:

While specific values can vary slightly depending on the production batch, key specifications generally include:

• Collector-Base Voltage (VCBO): Typically around 20V
• Collector-Emitter Voltage (VCEO): Typically around 12V
• Emitter-Base Voltage (VEBO): Typically around 3V
• Collector Current (IC): Typically around 30mA
• Collector Dissipation (PC): Typically around 150mW
• Transition Frequency (fT): Typically around 9 GHz
• Noise Figure (NF): Typically around 1.2dB at 1 GHz

The 2SC5772 is typically available in a small surface-mount package. Always consult the official datasheet from Hitachi or a reputable distributor for the most accurate and up-to-date specifications. Ensure proper impedance matching for optimal noise performance in high-frequency applications.
