TVS - Varistors, MOVs

Transient voltage suppressors, or TVS, are a type of electrical device used to protect other sensitive electronic components from various forms of electrical transients or surge events. TVSs can be generalized into two main categories: Varistors and MOVs (metal oxide varistors). In this article, we will discuss the application field and working principle of B72510T9200S172, a type of mixed varistor/MOV product. Varistors and MOVs are both electronic components used to suppress surges and transients. A varistor is a two-terminal nonlinear semiconductor device with a voltage-dependent, resistance-based switching characteristic. Varistors can absorb over-voltage transients and prevent them from reaching sensitive circuits. MOVs, on the other hand, are two-terminal, voltage-dependent resistors made of metal oxides. MOVs can dissipate large currents at high voltages to bypass the transient energy to ground.The B72510T9200S172 is a mixed varistor/MOV product, with the varistor and MOV components stackable to provide better protection. B72510T9200S172 utilizes bi-directional absorption of transient energy, thanks to the varistor and MOV components working together. This property of bidirectional absorption makes it suitable for use in a wide range of applications, from \'DC-DC converters and motor drives to portable IT and telecoms equipment.\'The working principle of B72510T9200S172 is relatively simple. When a transient voltage spike occurs, the MOV component conducts current as it absorbs the spike, thus shunting energy away from the sensitive circuitry. Meanwhile, the varistor element absorbs the spikes that exceeded the current capability of the MOV element. When the spike is over, the MOV opens up again, and the voltage across the circuit returns to its original value.The B72510T9200S172 also features bidirectional suppression, meaning it is able to respond to both positive and negative voltage transients. This telescopic action of moving also gives it excellent response to electrical transients, making it an ideal choice for applications that require fast protection. In terms of performance, the B72510T9200S172 offers superior two-stage protection, making it suitable for use in high-voltage applications. It features a one-piece structure with up to 5 stackable components that can be assembled according to specific application requirements. Moreover, the B72510T9200S172 supports a wide operating temperature range (up to 125°C) and offers superior transient immunity with high surge current capability.In conclusion, the B72510T9200S172 is a mixed varistor/MOV product that offers superior transient protection from both positive and negative transients with fast response times. It is suitable for use in a wide range of applications, including DC-DC converters and motor drives, as well as portable IT and telecoms equipment. Thanks to its superior surge current capability, wide operating temperature range, and one-piece structure with stackable components, the B72510T9200S172 is an ideal choice for high-voltage applications that require fast response times.
