Avago Technologies Introduces PIN Diodes in the Low-Cost, Lead-Free SOD-323 Package; Small Form-Factor Package Reduces Board Space for Small, Feature-Rich Wireless Portable Devices.SAN JOSE San Jose, city, United States San Jose (sănəzā`, săn hōzā`), city (1990 pop. 782,248), seat of Santa Clara co., W central Calif.; founded 1777, inc. 1850. , Calif. -- Avago Technologies Avago Technologies is an American company which was earlier the semiconductor products division of HP and later Agilent Technologies, before being spun off into a distinct legal entity. It holds more than 2,000 patents. today introduced three high-performance PIN diode A PIN diode is a diode with a wide, undoped intrinsic semiconductor region between p-type semiconductor and n-type semiconductor regions. A PIN diode obeys the standard diode equation only for very slow signals. chips in the low-cost, RoHS-compliant, lead-free SOD-323 (small outline diode) plastic package. The two-pin SOD-323 package has dimensions of only 1.7 mm x 1.25 mm x 0.95 mm, significantly smaller than the 3 mm x 2.5 mm x 1.1 mm form-factor offered by the three-lead SOT (small outline transistor)-23, and 2 mm x 2.1 mm x 1.1 mm offered by the SOT-323 packages. The three new products expand Avago Technologies' extensive range of surface-mount PIN diodes in industry-standard packages, including SOT-23, SOT-143, SOT-323 and SOT-363, while offering the same performance characteristics. In the new SOD-323 PIN diode series, the Avago HSMP-389Z is optimized for RF switching applications where low insertion loss The amount of loss attributed to a particular device being used in (inserted into) the system. For example, a circuit added to filter out unwanted frequencies may reduce the output current by some amount. See injection loss. , low series resistance at low current, and low capacitance are required. The HSMP-386Z is suitable for low-distortion and low-current switching applications as well as attenuation Loss of signal power in a transmission. Attenuation The reduction in level of a transmitted quantity as a function of a parameter, usually distance. It is applied mainly to acoustic or electromagnetic waves and is expressed as the ratio of power densities. applications that require low current or power consumption. The HSMP-381Z is optimized for low distortion and high-linearity attenuation. All versions are specified for operation at up to 3 GHz and address wireless infrastructure, CATV (Community Antenna TV) The original name for cable TV. It used a single antenna at the highest location in the community in order to deliver a quality signal to homes in areas with hilly terrain or other interference. , DBS (Direct Broadcast Satellite) A one-way TV broadcast service from a communications satellite to a small round or oval dish antenna no larger than 20" in diameter. LNB/multiswitch, mobile handset, cordless phone A wireless telephone that transmits to and receives signals from a base station within a range of a few hundred feet. Cordless phones are for local use and cannot travel long distances as can cellphones and satellite phones. See DECT and multihandset cordless. and WLAN See wireless LAN. WLAN - wireless local area network applications. "For today's RF applications that need only a single PIN diode, our customers prefer the smaller, less-expensive SOD-323 package over the SOT-23 and SOT-323," said Steve Saw CY, worldwide product marketing manager for silicon diode/RFIC products in Avago Technologies' Wireless Semiconductor Division. "To meet their needs, we are expanding our product package portfolio, while maintaining the performance characteristics they require for their demanding, next-generation wireless designs." Performance characteristics of the SOD-323 PIN diodes include: --The HSMP-389Z features low series resistance (Rs) of 3.8 ohms at 1 mA, 1.8 ohms at 5 mA, 1.5 ohms at 10 mA (typical at 100 MHz (MegaHertZ) One million cycles per second. It is used to measure the transmission speed of electronic devices, including channels, buses and the computer's internal clock. A one-megahertz clock (1 MHz) means some number of bits (16, 32, 64, etc. ); low total capacitance (CT) of 0.20 pF typ. at reverse voltage (VR) of 5 V at 1 MHz; and short carrier lifetime (t) of 200 ns at forward current (IF) of 10 mA and reverse current (IR) of 5 mA. --The HSMP-386Z features Rs of 15 ohms at 1 mA, 4.5 ohms at 5 mA, 1.5 ohms at10 mA (typ. at 100 MHz); CT of 0.23 pF typ. at 5 V VR and 1 MHz; and t of 500 ns at 50 mA IF and 250 mA IR. --The HSMP-381Z features Rs of 70 ohms at1 mA, 18 ohms at 5 mA, 7 ohms at 10 mA (typ. at 100 MHz); CT of 0.30 pF typ. at 5 V VR and 1 MHz; and t of 1500 ns at 50 mA IF and 250 mA IR. For applications requiring two or more PIN diodes, the three-lead SOT-23 or SOT-323, the four-lead SOT-143 or the six-lead SOT-363 are still a preferred choice, since they can contain up to four diodes in a single package, minimizing board space. U.S. Pricing and Availability The HSMP-389Z is priced at $0.11 each in 220,000 piece quantities, the HSMP-386Z at $0.14 each in 180,000 piece quantities, and the HSMP-381Z at $0.16 each in 150,000-piece quantities. These devices are available in 100-piece bulk packs and 3000 pieces on 7-inch tape-and-reel. Samples and production quantities are available now from Avago Technologies' direct sales channel and worldwide distribution partners.
