What is 2SD468? 20V, 1A, NPN Power Amplifier – Unisonic

What is 2SD468?

This is a silicon NPN transistor designed for use in a variety of low-power amplifier and switching applications. The 2SD468 is a silicon NPN transistor with a maximum collector-base voltage (Vcb) rating of 25V and a continuous collector current (Ic) rating of 1A. Therefore, it can safely handle a voltage of 20V and a current of 1A without any problems.

Description

The 2SD468 is 20V, 1A, NPN Power Amplifier. When a small current is applied to the base, it controls a much larger current between the collector and emitter, making the NPN transistor an effective amplifier or switch. It is suitable for use in a wide range of low-power amplifier and switching applications, such as audio amplifiers, voltage regulators, and low-frequency oscillators. Its low noise and distortion characteristics make it particularly well-suited for use in high-quality audio applications.

A NPN transistor is a type of bipolar junction transistor (BJT) that consists of two n-type semiconductor materials separated by a single p-type material.

Characteristics of NPN Transistors

1. Bipolar Junction: NPN transistors are bipolar junction transistors (BJT), meaning they have a structure consisting of three regions of alternating P-type and N-type semiconductors.

2. Current Amplification: NPN transistors are designed to amplify electrical current, and can be used in a wide range of electronic applications such as amplifiers, switches, and oscillators.

3. Forward Biased: In order to operate, the base-emitter junction of an NPN transistor must be forward biased, meaning that the base must be connected to a positive voltage relative to the emitter.

4. High Input Impedance: NPN transistors have a high input impedance, which means that they are less likely to draw current from the input source, and are therefore less likely to cause a drop in voltage across the source.

5. Inverted Output: NPN transistors are known for producing an inverted output relative to their input. That is, if the input signal is high, the output signal will be low, and vice versa. This behavior is due to the way the transistor is designed and is an important characteristic for many electronic applications.
