TVS - Varistors, MOVs, are devices that protect circuits from surge overvoltages from outside sources. Overvoltage usually occurs from lightning or other sources of electrical transients. Voltage levels can exceed the circuits rating, causing damage and failure. The surge voltage is typically suppressed and mitigated by a TVS which offers capacitance and inductance, providing transient protection to the sensitive electronics of the circuit. TMOV34S111EP is a commonly used TVS device. It is a surface mount diode designed to clamp and divert surge current and protect against electrostatic discharge.

TMOV34S111EP is an ultra-low capacitance transient voltage suppressor with an equivalent circuit capacitance of 7.5 pF. This capacitance improves signal transmission speed, providing outstanding protection against ESD and EFT pulses. TMOV34S111EP\'s built-in solid-state metal oxide varistor (MOV) element is designed to safely clamp and limit transient voltage surges induced by lightning, ESD, or other overvoltage transients.

The TMOV34S111EP features an open junction lead frame package design with a wide range of operating temperature from -55°C to +150°C. The device is a transient voltage surge suppressor with transient current limiting and low capacitance. It is well-suited for a wide range of applications such as computers, peripherals, telecommunications, networking, automotive, and consumer electronic products.

The TMOV34S111EP is designed to effectively dissipate high transient energy up to 10A peak for 8/20µs, and clamp transient events to a maximum peak voltage of 34V. An extra 4V absolute maximum rating tolerance is provided for the MOV element due to the high power scale with no guarantee of life. The device also integrates a high breakdown voltage, protecting electronic components from large current surges or spikes.

The TMOV34S111EP\'s peak impulse current handling capability is determined by its maximum clamping voltage and capacitance rate. It has a typical flat response to lightning, depending on the geometry of the transient source and the device\'s response. This flat response also results in low transient over-voltage pulse duration. Also, the device\'s low leakage current ensures minimal electrode erosion.

To sum up, TMOV34S111EP is a highly-integrated surface mount diode designed as a transient voltage surge suppressor with transient current limiting and low capacitance. It provides excellent protection for a wide range of applications from lightning, ESD, and other overvoltage transients. Its open junction lead frame package offers a wide operating temperature range from -55°C to +150°C. Also, the device has a high breakdown voltage that ensures maximum protection from current surges or spikes.
