Microchip MD0100DK6-G

Высокое напряжениеПоверхностный монтаж

Overview

MD0100DK6-G is a high voltage, two terminal, bi-directional, current-limiting protection device. The two terminals are interchangeable. 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 MD0100DK6-G can be considered as a normally closed switch with a typical switching resistance of 15O that allows 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 MD0100DK6-G can withstand up to ±100V across its terminals. A small amount of current, typical of 200µA, is allowed to flow through.The applications for the MD0100DK6-G are not limited to just ultrasound. It can also be used for resettable fuses to protect power lines, output short circuit protection, and data acquisition. The MD0100DK6-G is available in the SOT-89 package as a single channel device for ease of assembly. It is also available in a 4.0x4.0mm 8-Lead DFN package as a two channel device for high density requirements.
