The Westinghouse H769P7A is a high-performance radio transistor designed for use in various electronic applications. This transistor is a vacuum tube replacement, offering superior reliability and efficiency compared to traditional tubes.
The H769P7A is a pentode transistor, which means it has five terminals: the emitter, the base, two grid connections, and the collector. This configuration allows for greater control and versatility in circuit design. The transistor is rated for a maximum collector current of 500 milliamperes (mA) and a maximum collector-emitter voltage of 40 volts (V).
The H769P7A is designed to operate at an optimal temperature range of -20 degrees Celsius to 70 degrees Celsius. It is encapsulated in a rugged epoxy case, making it suitable for use in industrial and automotive applications where vibration and temperature extremes may be present.
This transistor features a high voltage gain of 120, which allows it to amplify small input signals into larger output signals. It also has a low noise figure of 5.5 decibels (dB), which makes it ideal for use in radio and audio applications where low noise is essential.
The H769P7A is specifically designed to replace the Westinghouse 6V6, 6V6G, 6V6GT, and 6V6LW vacuum tubes in various applications, including radio receivers, power amplifiers, and oscillator circuits. It is compatible with both positive and negative voltage supplies, making it a versatile choice for a wide range of electronic projects.
In summary, the Westinghouse H769P7A is a high-performance radio transistor that offers superior reliability, efficiency, and versatility compared to traditional vacuum tubes. It is a pentode transistor with a maximum collector current of 500mA, a maximum collector-emitter voltage of 40V, and a high voltage gain of 120. It is suitable for use in industrial and automotive applications, and can replace various vacuum tubes in radio and audio applications.
