TVS - Diodes are semiconductor devices which are designed to protect sensitive electronic equipment from electrical overstress caused by inductive spikes, electrostatic discharges, or lightning. Among such devices, the LVB14A-M3/5B is a diode array with 14 channels of surge protection.

Overview

The LVB14A-M3/5B is a 14 channel, surface mount device for protecting sensitive electronic circuitry from overvoltage transients. It is constructed using an array of Schottky diodes that are designed to reduce the voltage spikes generated by electrical transients. Each diode channel is rated for a maximum voltage of 24 volts and has a peak pulse power rating of 600 Watts. The device is designed to operate at temperatures between -40 degrees Celsius and +125 degrees Celsius.

Application Field

The LVB14A-M3/5B is designed to provide a range of surge protection for high-speed communications and general-purpose equipment. Its features make it ideal for applications in industrial, automotive, and mobile environments. The device can also be used in a variety of consumer electronics, such as laptop computers, flat panel monitors, and portable media players.

Working Principle

The LVB14A-M3/5B works by redirecting the voltage spike from the signal line to a low-impedance path, thus providing protection for the system circuit. This is achieved by connecting the anode of each diode channel to the source of the current and the cathode to the signal line. When a transient voltage is detected, the diode channels become forward biased and conduct current. This reduces the voltage spike on the signal line and prevents damage to the circuits.

The working principle of the device can also be used to provide overvoltage protection, as the device can be used to disconnect the power supply from the system in the event of a large surge. The device can be used to prevent permanent damage to the system by disconnecting the power supply before the voltage increases to a damaging level. This protection mode requires that an external jumper is connected to the diode channel which is then triggered by overvoltage.

Conclusion

The LVB14A-M3/5B is a diode array which is designed to protect sensitive electronics from electrical overstress. It can be used in a wide variety of applications, ranging from consumer electronics, to automotive, to industrial equipment. The device works by redirecting voltage spikes away from the system circuit to a low-impedance path, thus providing protection from electrical transients. The device can also be used to provide overvoltage protection, by disconnecting the power supply from the system in the event of a large surge.
