Press Release Summary:
With 42 ohm max on-resistance, DN2470 N-channel MOSFET minimizes power dissipation as well as voltage drops and is free from thermal runaway and thermally induced secondary breakdown. Depletion-mode allows construction of normally on solid-state relays and 2 terminal constant current sources. Breakdown voltage provides protection against high-voltage transients in NC solid-state relays, SMPS start-up circuits, converters, and constant current sources.

Supertex Releases Industry's First 700V DMOSFET
DN2470 Provides Protection for High Voltage Applications
SUNNYVALE, Calif., Jan. 31 -- Supertex, Inc. (NASDAQ:SUPX) today announced DN2470, a high voltage, N-channel depletion-mode MOSFET featuring a 700V breakdown voltage that provides protection against high voltage transients in normally closed solid-state relays, SMPS start-up circuits, converters and constant current sources. This high-speed device is the industry's first 700V depletion device.
With a 42-ohm maximum on-resistance, DN2470 minimizes power dissipation and voltage drops. Depletion-mode allows construction of normally on solid-state relays and two terminal constant current sources. This device has the power handling capabilities of bipolar transistors and with the high input impedance and positive temperature coefficient inherent in MOS devices. Characteristic of all MOSFET structures, the DN2470 is free from thermal runaway and thermally induced secondary breakdown.
"We're the industry leader in application-specific MOSFETs. The DN2470 is the only depletion device on the market with a 700V breakdown voltage," said Ahmed Masood, Supertex Director of Marketing. "With the DN2470 announcement, our MOSFET product offering now provides the widest range of high voltage switching solutions available."
DN2470 is available in a TO-252 (K4) package. This package is also "Green" or lead-free certified. Samples are available from stock. Lead-time for production quantities is 4 to 5 weeks ARO. Pricing for the DN2470K4 in 1K piece quantities is US$0.68. It is also available in wafer form, DN2470NW, and in die on adhesive tape, DN2470NJ. Consult factory for volume pricing.
