TVS (Transient Voltage Suppressors) devices are designed to protect sensitive equipment from voltage transients, which can be caused by a wide range of sources including lightning strikes, power inductive loads, capacitive switching surges, ESD (Electrostatic Discharge) events, and ground loop issues. Among the various TVS technologies, Varistors, MOVs, and V27ZT2Ps (27 Volt Zenner Transient Protectors) are some that are commonly used. This article examines the application field and working principle of the V27ZT2P device.

The V27ZT2P is designed to protect equipment from high-frequency voltage spikes. It has a nominal voltage rating of 27V and operates as a low-current, low-leakage protection device, meaning it can absorb and dissipate energy through its internal resistive element without overheating or shorting out. The V27ZT2P features a very fast response time, with a typical response time of 1 nanosecond or less, making it ideal for applications where a fast response time is essential. It also has a high reverse-breakdown voltage, meaning it can handle voltages that significantly exceed its nominal operating voltage.

The V27ZT2P is commonly used to protect electronic devices that are vulnerable to voltage transients. This includes personal computers, cell phones, power supplies, communications, automotive, medical, industrial, and aerospace equipment. It is especially useful in applications where a high level of EMI (electromagnetic interference) is present, as it is designed to absorb large voltages with minimal energy loss. The V27ZT2P also features a high capacitance-voltage ratio, making it suitable for applications that require a high CV (capacitance-voltage) protection.

The V27ZT2P works by dissipating energy due to any voltage transient/spike as heat. It has a zener diode core that limits the current, which in turn limits the voltage. The diode is placed between two terminals, and when the voltage spike exceeds its breakdown point, the current flows through the diode, dissipating the energy as heat. This prevents the voltage transient from reaching the sensitive components, thus protecting them from damage.

The V27ZT2P is typically used in series with other components in a circuit, and can be used in both AC and DC circuits. It is typically installed in a surface mount package, making it easy to mount and connect to the circuit board. Additionally, the V27ZT2P is typically rated for a wide temperature range, making it suitable for use in a variety of applications.

In conclusion, the V27ZT2P is an effective device for protecting sensitive components from voltage transients. It is fast acting, has a high reverse-breakdown voltage, has a high capacitance-voltage ratio, and is typically housed in a surface mount package. As such, it is well suited for use in a wide variety of applications, from consumer electronics to industrial and aerospace equipment.
