ZXTN4002ZTA Discrete Semiconductor Products

Introduction

The ZXTN4002ZTA is a bi-polar single transistor. It is a small signal device with very low collector-emitter saturation voltage and high gain bandwidth. The ZXTN4002ZTA is widely used in high-speed switching applications with its excellent switching characteristics. It is suitable for working in wide power supply voltage range from 3.0V to 25V.

Application field

The ZXTN4002ZTA can be used in a variety of applications, including switching circuits, amplifiers, low-power driver applications, high-frequency switches, and others. Its main use is in amplifier circuits that require high gain and high switching speed. Its low collector-emitter saturation voltage makes it an ideal transistor for use in low-power driver and protectors. It is also suitable for peripheral switching circuits and as a stage amplifier.

Working principle

The ZXTN4002ZTA has a three-lead configuration, one base (B), one collector (C), and one emitter (E). The base acts as a control point between the collector and the emitter. The current passing through the base can control the current flowing through the collector-emitter junction. When the base current is increased, the collector current increases and vice versa. When the base current is cut off, no current flows through the collector-emitter junction, and the transistor is in the OFF state.

The current flowing from collector to emitter creates a voltage drop across the collector-emitter junction. This voltage is known as the collector-emitter saturation voltage. If the collector-emitter saturation voltage exceeds the collector-base voltage, the transistor remains in the OFF state. If the base voltage is increased, the collector-emitter saturation voltage falls, and the transistor turns ON. This is known as the saturation voltage cut-off (SVCO) effect.

Advantages

The ZXTN4002ZTA is a very versatile transistor with excellent switching characteristics. It has a wide power supply voltage range, making it suitable for use in many applications. It has a low collector-emitter saturation voltage, which allows it to strictly control the current flowing through it. Furthermore, this device is also available in a dual package, allowing two transistors to be operated in the same circuit, which is ideal for power distribution applications.

Conclusion
