MD0105 Overview
The Supertex MD0105 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 monly referred to as a T/R (transmit and receive) switch. The MD0105 can be considered as a normally closed switch with a typical switch resistance of 15Ω, allowing small signals to pass.
MD0105 Key Features
- Up to ±130V input voltage protection -- Low on resistance
- 15Ω typical -- Fast switching speed -- Four electrically isolated channels -- No external supplies needed
