Digi-Key stocking Skyworks’ diodes

Digi-Key Corp of Thief River Falls, MN, USA (one of the world’s fastest-growing electronic component distributors) is now stocking PIN, Schottky, and varactor diodes from Skyworks Solutions Inc of Woburn, MA, USA, available via its global websites (and to be featured in future print and online catalogs).

This follows Skyworks (which manufactures linear products, power amplifiers, front-end modules and radio solutions for handset and infrastructure equipment) entering into a global distributor agreement with Digi-Key last June.

Regarding PIN diodes, Skyworks’ SMP1302 series is designed for high-power, high-volume switch and attenuator applications from 10MHz to beyond 6GHz (encased in a surface-mountable plastic QFN package, capacitance is a low 0.3pF). The SMP1345 series, available in the tiny 0402 package, is designed for low-noise block (LNB), wireless local-area network (WLAN), and switch applications from 10MHz to 6GHz. The SMP1321 and SMP1340 series have very low capacitance and series resistance for fast-switching, high-isolation applications. The Pi configuration SMP1307-027LF is suited to CATV and Infrastructure low-distortion attenuator applications.

Skyworks’ Schottky diodes are low-cost, surface-mountable, plastic-packaged, and designed for RF and microwave mixers and detectors. The devices may be used at frequencies up to 10GHz and are available in SC-70, SC-79, SOD-323, SOT-23, and LGA packages. Wiring configurations include singles, common cathode, series pairs, unconnected pairs, and dual series pairs.

Skyworks’ varactor diodes are designed for use in voltage controlled oscillators (VCOs) with a low tuning voltage operation. The family includes the SMV1234, SMV1247, SMV1249 and SMV1255 series of silicon hyper-abrupt junction diodes. The SMV1413 series is suited to use in VCOs that call for tight capacitance tolerances.
