Packaged in a D-61 casing, the CNQ series of 110A Schottky diodes from International Rectifiers (IR) are claimed to offer twice the current density over competing devices in SOT-227 or TO-247 type packages. The diodes are also claimed by the company to offer >35 percent higher current carrying capability over IR's previous generation of devices using the D-61 package.

The increased current density makes the diodes suitable for output rectification of switch-mode power supplies for telecom and datacom systems, as well as servers, workstations, and mainframes. They can also be used in OR'ing output converters in N+1 redundant power supply systems.

The D-61 package is available in surface-mount and through-hole versions, and features a thicker base plate and heavy-duty leads for the increased current handling capability. Improved bonding lowers the forward voltage drop by up to 20 percent, thereby reducing conduction losses and improving thermal performance.

The diodes are available in rated voltages of 15 (115CNQ015A), 30 (112CNQ030A), 45 (110CNQ045A), and 100V (113CNQ100ASL, 113CNQ100ASM, 113CNQ110A).

The 15V version provides an output rectification of 3.3V, while the 30V model offers 5V. The 45V allows rectification between 12V to 15V, while the 100V versions provide 24V to 36V rectification.

The 115CNQ015A is priced at $6.90 each in quantities of 10,000.
