LC90

LC90 Application Field and Working Principle

LC90s are one of the many types of Transient Voltage Suppression (TVS) Diodes which are used to protect integrated circuits from high voltage transients. The pulse voltage used in LC90s is applied by switching or clamped to the circuit to be protected. This is done by mounting a diode between the voltage source and the circuit. In this way, excess voltage beyond the rated level is discharged through the diode. This will protect the circuit from damage due to the high current spikes.

TVS Diode Working Principle

The basic TVS diode works by utilizing a back-to-back diode array. This array is typically composed of a low voltage Zener diode and a high voltage Zener diode. The low voltage Zener diode (LVZD) is designed to conduct current when the voltage across it is greater than its threshold voltage. Similarly, the high voltage Zener diode (HVZD) is designed to conduct current when the voltage across it is less than its threshold voltage.

When the potential difference of the input voltage reaches a certain predetermined level, the low voltage Zener diode begins to conduct and the high voltage Zener diode begins to block current. This sequence of diode conduction and blocking creates a transient voltage suppression (TVS) which dissipates the over-voltage current energy, thus protecting the circuit components from large voltage spikes or ESD.

Applications of LC90s

LC90s are used in many applications where transient voltage suppression is necessary. Some of these applications include: computer electronic parts, air and pressure switches, automotive and industrial applications, lightning protection, power supplies, medical equipment, motors and generators, and communication systems. In addition, LC90s are often used to protect sensitive semiconductor components such as microprocessors, memories, and transistors from ESD and voltage spikes.

LC90s also provide protection from over-voltage or over-temperature conditions. They can be used to protect data lines, control lines, and power supply lines for a wide range of applications. LC90s offer superior protection at an affordable cost and can be used in both commercial and industrial applications.

In addition, LC90s are ideal for applications where fast transient response and low clamping voltage are desired. The fast response time allows the LC90s to protect sensitive components from voltage spikes before they can cause any damage. Moreover, LC90s are capable of handling high surge current, making them perfect for use in power supplies, lightning protection and other industrial applications.

Conclusion

LC90s are a type of TVS diode with many applications. They are designed to protect circuits from high voltage transients, ESD and over-temperature conditions. LC90s offer superior protection, fast response time and low clamping voltage, making them suitable for use in a wide range of commercial and industrial applications.
