SMOV34S621NP is a type of TVS – Varistors, MOVs and belongs to the SMOV Series of High Energy Protection Transient Voltage Suppressors. This type of device is used to safeguard components against destructive voltage transients due to electrostatic discharge (ESD) and lighting strikes, as well as surges due to operating and induced AC line voltage.SMOV34S621NP has a clamping voltage of 34V, breakdown voltage of 60V, and peak pulse power rating of 600W at 10/1000μs. It also has a peak pulse current rating of 600A at 10/1000μs, and a maximum leakage current of 10μA at 10V. This device has a ceramic body that provides high thermal conductivity and is easy to mount.SMOV34S621NP is used in a variety of applications, such as telecommunications, industrial control systems, consumer electronics, automotive systems, and server and networking equipment. This device is designed to be low capacitance and high energy rating. It has low clamping voltage, fast response time, and provides protection against high-speed, high-voltage pulses. It is also designed to be RoHS compliant, and provides excellent thermal stability and high reliability.The working principle of SMOV34S621NP is based on the principle of Zener diode or metal-oxide varistor (MOV) technology. The Zener diode or MOV technology is typically used to protect sensitive components from over-voltage transients caused by electrostatic discharge (ESD) and lightning strikes. The device uses a zener diode or MOV element to constantly monitor the power line voltage. When the voltage passed to the sensitive component exceeds a certain level, the zener diode or MOV quickly clamps the voltage to its breakdown voltage and protect the component from potential damage.SMOV34S621NP also works on the principle of thermal management. This type of device has a built-in thermistor which, when exposed to higher temperatures caused by high peak current power pulses, quickly dissipates the heat and protects the components from damage. This device also has a built-in voltage device which quickly clamps the voltage to its breakdown voltage and prevents the voltage from exceeding its maximum rating.SMOV34S621NP is available in both radial and SOT packages with straight or right-angle leads. It is designed to be surface mountable and to be used in combination with other types of protective components to help form a complete protective system.The SMOV34S621NP is an important addition to the transient voltage surge suppressor market and provides excellent protection against high-voltage and high-current surge transients. This device has fast response time, low leakage current, low power consumption, and is RoHS compliant. This device is ideal for a variety of applications and provides reliable protection from damaging voltage transients.
