The KTA733B-Y-AT/P is a PNP Epitaxial Planar Transistor manufactured by KEC. This transistor is designed for low noise amplification in audio and other sensitive electronic circuits.

Applications:

• Low-noise audio amplifiers
• Microphone preamplifiers
• Tape recorder input stages
• Sensor amplifiers
• General-purpose amplification

Features:

• Low Noise Figure (NF = 1dB Typ. @ 1kHz)
• High Current Gain (hFE = 120 ~ 270)
• Low Collector Output Capacitance (Cob = 3.0 pF Typ.)
• Complementary to KTC945

Benefits:

• Excellent signal clarity in audio applications due to the low noise figure.
• High amplification capability with high current gain.
• Reduced signal distortion due to low collector output capacitance.
• Simplified circuit design using its complementary NPN transistor.
