Lower losses for
Schottky barrier diodes
Shindengen's J-series Schottky barrier diodes are extremely low reverse leakage devices that maintain low losses even at high operating temperatures
Shindengen's J-series Schottky barrier diodes (SBDs) are extremely low reverse leakage devices that sustain their low-loss characteristic even at high operating temperatures where conventional devices display high reverse-current losses. Typical reverse leakage current is less than one-tenth that of conventional SBDs.

Shindengen's new bridge diodes feature an optimised leadframe construction for enhanced thermal radiation, to deliver improved reliability in service
When used in telecomms PSUs, AC mains adapters and other power conversion equipment, where market pressure for the smallest possible enclosure prevents rapid heat dissipation, the J-series SBDs allow convertors to meet environmental demands for higher efficiency to reduce energy requirements.
The DF20JC10, rated at 20A/100V, uses Shindengen's J-series technology to achieve extremely low IR of 0.7mA.
This compares with around 10mA typical IR for a conventional SBD of similar rating.
This dramatically improves operating efficiency, with no significant increases in losses even above 100C.
For 120V devices, reverse leakage is improved more than 100-fold.
The full range of J-series devices typically achieve similar improvements over comparable conventional SBDs.
There are currently 19 J-series family members, with output current up to 30A, and rated at 40, 60, 100 or 120V withstand voltages.
Available devices range from the SF10JC6 rated up to 10A and 60V withstand voltage and delivered in the industry standard FTO-220 package and the DF30JC12, 30A, 120V device in the STO-220 package.
