Varistors, also known as voltage dependent resistors (VDRs), are two-terminal passive components with variable resistance that responds to the amplitude of applied voltage. The ERZ-E10A271 is such a component, developed and manufactured by ROHM Semiconductor. It is a popular TVS (transient voltage suppressor) component for low voltage applications.

The ERZ-E10A271 is a symmetric Varistor designed for input protection against voltage transients such as ESD (electrostatic discharge) and EFT (electrical fast transient) pulses. It features a low clamping voltage with high energy absorption, making it ideal for low voltage applications. It can withstand up to 1,000 volts and has an energy absorption rating of 270 joules, and it is capable of carrying currents of up to 45A.

The ERZ-E10A271 is a low profile component with dimensions of 4.5mm x 5mm, ideal for integrating into compact spaces. It is a thermally and mechanically stable device manufactured in a durable ceramic package with gold-plated high temperature tin solder ball contacts. With a wide operating temperature range of -40° to +85°C, it can be used in wide range of applications, from automotive and consumer electronics to industrial control systems.

The working principle of the ERZ-E10A271 utilizes the non-linear conductive characteristic of varistors. When the voltage across the varistor is lower than the rated voltage, the varistor acts as an open circuit. However, when the applied voltage reaches the rated voltage, current will begin to flow, causing the resistance to decrease with increasing voltage. This helps prevent voltage surges from causing permanent damage to sensitive electronic components.

The ERZ-E10A271 is a versatile Varistor designed for low voltage protection applications in a variety of industries. This component is a reliable and cost effective solution for protecting a range of electronic systems from over voltage transients. With a low clamping voltage, high energy absorption and a wide operating temperature range, it is well suited for integration into low voltage systems and circuits.
