TVS (transient voltage suppressors) and MOV (metal oxide varistors) are components that are commonly used in both digital and analog circuits in order to prevent damage caused by unexpected voltage spikes. An important factor in ensuring a circuit’s stability is the ability to protect it from voltage surges or transients, either internally generated from the device or externally introduced from other components. The V27ZA4 is a MOV that does just that, providing protection against any transient voltages that may occur.

V27ZA4 components are composed of sintered metal oxide material that has been attached to two lead terminals. The metal oxide material is formed in such a way that the components are able to detect when the surrounding voltage has surpassed the MOV’s threshold. Once this threshold has been surpassed, current will flow through the MOV, which will then dissipate the incoming voltage as heat. In this way, the V27ZA4 effectively serves to protect components in the circuit from any unexpected and potentially damaging voltage spikes.

V27ZA4s are primarily used in industrially certified applications, such as control and automation systems, and other harsh environments that require a high level of protection, such as automotive, railway, and avionics systems. The V27ZA4 also has a fast response time in the event of an unexpected voltage spike, which ensures that it can act effectively and quickly protect the rest of the components in the circuit.

The V27ZA4 offers several additional benefits that make them a popular choice for many types of applications. Firstly, they are low-profile components, so they can fit into tighter spaces in the board layout. Additionally, their large clamping voltage makes them resistant to unwanted noise, and their low capacitance reduces the effect of transient noise in the circuit.

The V27ZA4 is also known for its high surge current capability, allowing it to withstand higher levels of shock without being destroyed. This is especially important in applications that are subject to momentary power outages or voltage fluctuations, as the MOV can absorb and dissipate the energy instead of allowing it to damage the underlying components. For this reason, it is an ideal choice for harsh environments where it will be exposed to large levels of transient voltages.

The V27ZA4 is a reliable and popular choice for protecting circuits from any unexpected and potentially damaging voltage spikes. Its low profile allows it to be used in tight spaces and its high surge current capability ensures that it can withstand factory generated transients without being damaged. Additionally, it has a fast response time, which means that it can act quickly in the event of a voltage spike, protecting the surrounding components from being damaged. For these reasons, it is a commonly used component for industrial and harsh environment applications that require extra protection.
