Transient Voltage Suppressor (TVS) diodes can be used for a variety of applications, but the main purpose of these diodes is to protect electronic circuits from voltage spikes. The SMCJ200A-H is one such diode, designed to protect against high-energy, electrostatic transient voltage. This article will discuss the applications and working principle of this device.

Application

The SMCJ200A-H can be used in a wide variety of applications, including computer, automotive, telecommunications, industrial control, appliances, power supplies, and printing systems. It has an operating voltage range of 5.0-220 V, with a maximum power rating of 2.5 W. The device is also designed to withstand high-energy pulses, making it well-suited for protecting against electrostatic discharges. Additionally, because of its high peak pulse current rating and low capacitance, the SMCJ200A-H can be used for ESD protection on both data and signal lines.

Working Principle

TVS diodes are semiconductor devices that are designed to limit overvoltage transients. They work by “clamping” any incoming voltage above a certain level to a predetermined value. In the case of the SMCJ200A-H, this clamping voltage is up to 220 V. This device is an effective form of protection, as it does not degrade the signal quality of the system it is protecting.

When the SMCJ200A-H is exposed to a high-energy voltage transient, its breakdown voltage is exceeded, and it becomes forward biased. This action causes the device to conduct current, which effectively “clamps” the voltage to a predetermined level. This process is known as “clamping” and it is an effective form of protection against voltage spikes.

Once the SMCJ200A-H has clamped the transient voltage, the device is confused. It springs back to its original, quiescent state, and dissipates the energy it has clamped from the incoming transient. This energy is dissipated as heat, and it is important to ensure that the device is mounted on a suitable heatsink in order to allow for the proper dissipation of heat over time.

The SMCJ200A-H is an effective, high-performance diode that offers reliable protection against transient voltage spikes. It is designed for a wide variety of applications, and its low capacitance and high peak pulse current rating make it ideal for ESD protection on both data and signal lines. Additionally, its high operating voltage makes it suitable for a wide range of applications.
