General Description
The Supertex MD0100 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 MD0100 can be considered as a normally closed switch with
a typical switching resistance of 15Ω 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 MD0100 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 MD0100 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 MD0100
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.
