SI7386DP-T1-GE3 is a field effect transistor (FET), specifically a single type of MOSFET, that is primarily used in audio power amplifier circuits. It is notable for its low gate drive power, good linearity and low distortion rate. While its main application is in the design of power amplifiers, it can also be used in various other circuits, such as analog and digital signal processing applications.

Application Field

The SI7386DP-T1-GE3 is a cost-effective power MOSFET suitable for audio power applications due to its low gate drive power, low distortion rate and good linearity. It can be used to design power amplifiers for consumer-level audio applications including home hi-fi systems, public address systems and car stereos. It can also be used in professional audio applications such as mixing consoles, active speakers and stage monitors.

This device is ideal for audio power applications due to its low gate charge and high on-state drain current. It is also suitable for audio signal processing applications, such as those involving distortion analysis, due to its low distortion rate, which is low even at high input power levels. Additionally, it is able to drive a wide range of capacitive and inductive loads while remaining stable.

Working Principle

The SI7386DP-T1-GE3 is a self-biased FET and requires no external biasing. It is based on an insulated-gate field effect mechanism known as a Metal-Oxide-Semiconductor (MOS) structure. This type of structure consists of two metallic layers, an insulating layer of oxide sandwiched between them, and a floating gate. The insulated gate is used to control the current flow and is able to control the voltage between the source and drain, which is a characteristic of a MOSFET.

The SI7386DP-T1-GE3 has a maximum drain-to-source voltage of 30V, and an on-state drain current of 19A. The device has a low gate drive power, meaning it can be easily driven by a low-power signal source. As it is a self-biased FET, it does not require an external power supply for its operation.

The SI7386DP-T1-GE3 is protected against static electricity by its built-in diode-like structure. This structure is able to provide protection against static electricity and related transients. Additionally, the device has thermal protection, which is able to protect the device from damage caused by undesirable operating temperatures.

Conclusion

The SI7386DP-T1-GE3 is an ideal device for audio power applications due to its low gate drive power, low distortion rate and good linearity. Additionally, due to its self-biased capability, it does not require an external power supply. The device also has static and thermal protection, making it a very reliable choice for audio applications. It can be used in consumer-level systems, as well as professional audio applications such as mixing consoles and active speakers.
