MD0105

Four-Channel

High Voltage Protection T/R Switch

Features

General Description

► Up to ±130V input voltage protection

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 commonly

referred to as a T/R (transmit and receive) switch.

► Low on resistance - 15Ω typical

► Fast switching speed

► Four electrically isolated channels

► No external supplies needed

The MD0105 can be considered as a normally closed switch with

a typical switch resistance of 15Ω, 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

MD0105 can withstand up to ±130V across its terminals. A small

amount of current, typically 200µA, is allowed to ﬂow through.

Applications

► Medical ultrasound imaging

► NDT applications

► Fast resettable fuses

► High side switches

► Data acquisition

The MD0105 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 MD0105 is

available in an 18-Lead 5x5mm DFN package as a four-channel

device.
