MD0105 - 4-Channel High-Voltage Protection T/R Switch

General Description

The MD0105 is a high-voltage current-limiting protection device.

It is designed to protect a low-noise receiver from high-voltage transmit pulses in ultrasound applications.

The MD0105 is commonly referred to as a T/R (transmit-and-receive) switch.

Key Features

  • Up to ±130V Input Voltage Protection.
  • Low On-Resistance.
  • 15Ω Typical.
  • Fast Switching Speed.
  • Four Electrically Isolated Channels.
  • No External Supplies Needed.
