JAN2N3501

The JAN2N3501 is a high gain, NPN, silicon transistor used mainly in audio-frequency low-power amplifier and switching applications. It is rated for a collector current of 6.8 mA, a voltage of 16 V, and a power rating of 150 mW. Its switch is rated for a collector current of 4.0 mA and a power rating of 200 mW.

Overview

The JAN2N3501 is an NPN type single-transistor circuit. It works by allowing electrons to flow into the base region and collecting those electrons at the collector region. This type of operation is known as an “emitter-follower”. In an NPN transistor, the current flow is through the emitter-follower, which is controlled by the amount of current that passes through the base region. The current gain of the transistor is determined by the ratio of the collector current to the base current.

Application Fields

The JAN2N3501 can be used in a variety of applications. In audio-frequency low-power amplifiers and switching applications, the transistor amplifies or switches an input signal. It can be used for both linear and switching applications. Additionally, it can be used in switching and logic applications, because of its fast switching capabilities. As an NPN type transistor, it can be used as the input stage in logic gate circuits, or in buffer stages of logic circuits.

Working Principle

When a voltage is applied to the base-emitter junction, it creates an avalanche effect, allowing electrons to move from the emitter to the collector. The voltage at the base controls the current at the collector. An increase in the base voltage increases the current at the collector, resulting in a greater output current. Conversely, a decrease in the base voltage decreases the output current. The gain of the transistor is determined by the ratio of the collector current to the base current.

The JAN2N3501 is a versatile transistor with fast switching properties, allowing it to be used in audio-frequency low-power amplifiers and switching applications. Its high gain and fast switching capabilities make it a suitable choice for powering switching or logic circuits. In addition, it can also be used in both linear and switching applications. Its low-power rating and low-voltage requirements make it a great choice for applications with limited power, current, or voltage requirements.
