The QS8K21TR is a product made by Motorola Inc. that is used in various applications. It is a power MOSFET array that is capable of supplying up to 5.3A at 628 volts. It is a high-current switch used in many different applications. It has an array of eight power MOSFETs that can each be switched independently and have secure ON-state resistance.

Application Field

The QS8K21TR is typically used in power supply, motor control, and other high current switching applications. It is widely used in telecommunication systems, uninterruptible power supplies, and motor control systems. The device is designed to provide reliable switching performance with increased power density and enhanced noise immunity. It is designed to have a secure ON-state resistance, allowing for the device to handle high currents without additional protection.

Working Principle

The basic working principle behind the QS8K21TR is its array of power MOSFETs. Each power MOSFET is individually controlled and can be individually switched. This allows for the device to handle high currents reliably and with increased power density. In order to maintain a secure ON-state resistance, the power MOSFETs must be properly sized and placed. This ensures that the current will not exceed the maximum rating, and that the switch will not fail under load.

The device also has enhanced noise immunity, which allows it to switch on and off without creating too much interference. This is helpful in applications where noise interference can cause problems. The device is designed to be highly reliable, and is capable of withstanding multiple switching cycles without failing.

The QS8K21TR is designed to be used in applications that require fast switching times. It is designed to be capable of switching at speeds of up to 500KHz. This makes it ideal for applications that require fast response times and high current switching.

The device is also designed to be used in harsh environments. It is designed to be able to withstand high temperatures and vibration without fail. It is also designed to tolerate electrostatic discharge and other forms of electrical interference. This makes the device suitable for use in environments where there is the potential for electrical interference.

Conclusion

The QS8K21TR is a high current switch array made by Motorola Inc. It is designed for use in various applications, especially in power supply and motor control. It has an array of eight power MOSFETs that can each be independently switched, and has secure ON-state resistance. The device is designed to be highly reliable, with enhanced noise immunity and a fast switching time of up to 500KHz. It is also designed to tolerate high temperatures, vibration, and electrostatic discharge. This makes it suitable for use in harsh environments. The QS8K21TR is an excellent choice for applications that require reliable, fast switching and high current switching.
