2 HSMS-282x Surfac Mount RF Schottky arrir iods ata Sht scription/pplications Ths Schottky diods ar spcifically dsignd for both analog and digital applications. This sris offrs a wid rang of spcifications and packag configurations to giv th dsignr wid flxibility. Typical applications of ths Schottky diods ar mixing, dtcting, switching, sampling, clamping, and wav shaping. Th HSMS 282x sris of diods is th bst all-around choic for most applications, faturing low sris rsistanc, low forward voltag at all currnt lvls and good RF charactristics.

4 iod urnout ny Schottky junction, b it an RF diod or th gat of a MSFT, is rlativly dlicat and can b burnd out with xcssiv RF powr. Many crystal vido rcivrs usd in RFI (tag) applications find thmslvs in poorly controlld nvironmnts whr high powr sourcs may b prsnt. xampls ar th aras around airport and F radars, narby ham radio oprators, th vicinity of a broadcast band transmittr, tc. In such nvironmnts, th Schottky diods of th rcivr can b protctd by a dvic known as a limitr diod. [5] Formrly availabl only in radar warning rcivrs and othr high cost lctronic warfar applications, ths diods hav bn adaptd to commrcial and consumr circuits. vago offrs a complt lin of surfac mountabl PIN limitr diods. Most notably, our HSMP-4820 (SOT-2) can act as a vry fast (nanoscond) powr-snsitiv switch whn placd btwn th antnna and th Schottky diod, shorting out th RF circuit tmporarily and rflcting th xcssiv RF nrgy back out th antnna.
