Schottky Barrier

Signal Schottky diodes are the most versatile devices in this family. They are used for routing signal tasks, rail-to-rail protection, RF applications such as balanced mixers and demodulators. Devices above 100 mA join the converter application field with rectification tasks, or discrete OR-ing function. Pin-outs are available in both axial and surface mount packages.

Power Schottky diodes combine low voltage drop characteristics with negligible or zero recovery. The range from 15 to 175 V and 1 to 240 A covers all application needs from OR-ing to 48 V converters and battery chargers to welding equipment. The package offer is broad, with through-the-hole and surface mount industry standard outlines. The new features are the avalanche specification of all types, the 120 V and 150 V VRRM and the high current TO-220 and D2PAK devices. Last but not least, the STPS 170 V series, with its 170 V VRRM and efficient use of its avalanche characteristics, can replace 200 V bipolar devices with a better voltage drop/recovery/EMC trade-off result.
