ERZ-V14D911

Diode (TVS) – Varistors and metal oxide varistors (MOVs) are a common form of overvoltage protection. These devices absorb surges and spikes in voltage and provide an acceptable level of protection against damaging levels of ESD and EMI energy. The ERZ-V14D911 is a TVS-Varistor device that is designed to protect circuits from damaging transients. It will absorb transients up to 1500W peak over a wide range of frequencies.

The ERZ-V14D911 has two main applications:.

• ESD Protection: The ERZ-V14D911 is specifically designed for use in ESD sensitive applications. It can absorb ESD voltages up to 15 KV and dissipate them harmlessly across the device. This prevents damage to sensitive electronics and helps to extend the life of the devices.
• EMI/RFI Protection: The ERZ-V14D911 can also provide protection from EMI/RFI noise, which can interfere with signals and cause errors in digital circuits. The device can absorb high-frequency energy up to 1.5GHz and dissipate it harmlessly across the device.

The working principle of the ERZ-V14D911 is based on the fact that when voltage across the device exceeds the rated value, it will trigger a varistor effect which will actively absorb the energy spike. This works by the device operating in a non-linear manner when the electrical field is strong enough to allow the current to flow through the device. The device also acts like a short circuit, shunting the surge away from the circuitry.

The TVS-Varistor ERz-V14D911 has an operating temperature range between −55°C and 150°C and is designed to meet the industry-standard IEC 61000-4-2, level 4, according to ESD 8kV (contact discharge). The device is provided in a 7.5 X 4.5 X 1.2mm chip size which is suitable for most high-density electronic applications. The typical capacitance value is 13pF at 1MHz, making it an ideal device for ESD protection.

In summary, the ERZ-V14D911 is a TVS-Varistor device designed for use in ESD and EMI/RFI sensitive applications, providing effective protection for circuits against damaging transients up to 1500W peak power. It has a low capacitance value and is suitable for a wide range of power supplies, offering excellent performance at an affordable cost.
