Transmit/Receive Switch From Supertex Guards Ultrasound Receivers From High Voltage Pulses

MD0101 Protects Components in Medical Ultrasound Applications

SUNNYVALE, CA--(Marketwire - May 3, 2011) - Supertex, Inc. (NASDAQ: SUPX), a recognized leader in high voltage analog and mixed signal integrated circuits (ICs), today introduced the MD0101, a four channel, high voltage, bi-directional voltage protection device with integrated clamp diodes. MD0101 protects low noise receivers in medical ultrasound applications from high voltage pulses.

MD0101 features fast switching speeds and a typical switch resistance of 15 ohms that allows small signals to pass. Once the voltage drop across its two terminals exceeds +/-1V, it will begin shutting down. In shut down mode, the device can withstand up to +/-100V across its terminals.

"The introduction of MD0101 strengthens Supertex's family of ICs for high performance medical ultrasound applications," states Stephen Lin, Vice President of Marketing for Supertex. "By integrating clamp diodes in a compact, DFN package, we've provided medical ultrasound system designers with a higher density T/R switch for their applications."

The MD0101 is available in a 5x5mm, 18-lead DFN package (MD0101K6-G). The part is RoHS compliant. Samples are available from stock. Lead-time for production quantities is 4-6 weeks ARO. Pricing is US$3.26 for the MD0101K6-G, in 1K quantities.
