Microchip MD0105K6-G

Высокое напряжениеПоверхностный монтаж

Overview

MD0105K6-G is a high voltage current limiting protection device. It is designed to protect a low noise receiver from the high voltage transmit pulses in ultrasound applications and is commonly referred to as a T/R (transmit and receive) switch.The MD0105K6-G can be considered as a normally closed switch with a typical switch resistance of 15O, allowing small signals to pass. Once the voltage drop across the two terminals exceeds a nominal value of ±2.0V, the device will start to turn off. In the off state, the MD0105K6-G can withstand up to ±130V across its terminals. A small amount of current, typically 200µA, is allowed to flow through.The MD0105K6-G is not limited to just ultrasound applications. It can also be used for resettable fuses to protect power lines, output short circuit protection, and data acquisition. The MD0105K6-G is available in an 18-Lead 5x5mm DFN package as a four-channel device.
