The ERZ-E11A271 belongs to the category of TVS (Transient Voltage Suppression) - Varistors, MOVs (Metal Oxide Varistors), and is used in various applications for electrical and electronic protection devices. It is an ideal choice for medium current and medium voltage applications such as uninterruptible power supplies, AC-DC converter, DC-DC converters, lighting systems, industrial, and consumer electronics.

The ERZ-E11A271 from PANJIT is an advanced, gas-filled, bi-directional, composite type of semiconductor varistor. It works on the principle of electrostatic discharge protection. This type of voltage suppressor is designed to protect electronic equipment from high-energy transients such as those generated by lightning or static electricity. It is capable of limiting inrush current, clamping over-voltage spikes, and suppressing switching transients. This protection device helps in increasing the lifetime of circuit components by decreasing vibrations.

The ERZ-E11A271 is available in many packaging options including die pad, chip, small pack, and TO-252 (IPAK). It works well in temperatures ranging from -55°C to 150°C with an operating area of up to 400V. The rated maximum operating voltage (Vrwm) is 95V, while the rated peak non-repetitive current (Ipp) is 500A (tp=8/20μs). It has a wide range of capacitance (C=45.6 pF – 1.035 pF), a maximum leakage current of 0.5 μA and a minimum insulation resistance of 1 GΩ.

In terms of applications, the ERZ-E11A271 is suitable for voltage level transients, over-voltage suppression, inrush current limitation, reverse surge breakdown, and initial DC breakdown. It is also used in rectifier circuits, bridge converters, storage battery protections, transformers, and UPS for protection against high-energy transients. Its low-leakage current, low-capacitance, high non-linear coefficient, and fast response time aids in protection of circuits, components, and electric devices.

In conclusion, the ERZ-E11A271 is a cost-effective, high-performance, and reliable transient voltage suppression device with a wide range of features suitable for various applications. Its excellent protection performance significantly improves the safety and performance of the circuit while its wide operating temperature range and low-leakage current ensure superior reliability and long-term performance.
