International Rectifier Corp. (IR, El Segundo, CA) introduced new 15V and 20V Schottky diodes for server and telecom power systems that are tailored for output rectification and output ORing circuits. The new devices have as much as 25% lower forward-voltage drop and 14% lower reverse-leakage current compared to industry-standard devices, according to the company.
The 80CPTN015 is rated at 15V; is housed in the TO-247 package; and features a maximum junction temperature of 150°C, a 12% reduction in forward-voltage drop, a 68% lower reverse-leakage current, a maximum forward-voltage drop of 340mV/40A at 125°C, a 10% reduction of power dissipation, and a 5V output rectification.
The 80CPT015 trench Schottky diode in the TO-247 package is rated at 15V, has a typical forward-voltage drop of 270mV at 125°C, and offers 20% lower forward-voltage drop and 14% lower reverse leakage current compared to a typical Schottky diode. The 80CNT020 in the D61 package is rated at 20V, featuring a 240mV voltage drop at 125°C, which is 25% lower compared to other typical Schottky diodes. The low forward-voltage drop makes the 80CNT020 suitable for high-current ORing applications up to 15V.
The 60CTT015 and the 60CTTN015 are 15V devices in the TO-220 package, with a typical voltage drop of 0.28V at 30A and 0.33V at 30A, respectively. The 60CTT015 is targeted towards ORing applications and has a Tjmax of 125°C. The 60CTTN015 has a max junction temperature of 150°C. The leakage current of the 60CTTN015 is 250mA at 125°C, making it suitable for operation up to a Tjmax of 150°C, without any fear of thermal runaway.
IR’s new Schottky diodes are available immediately. Pricing begins at $1.18 each in 10,000-unit quantities for the 60CTT015.
