Qspeed silicon diodes utilize merged PIN technology to provide a balance between soft switching and low reverse recovery charge (Qrr), reducing EMI and lowering output noise.
At TJ of 125°C, the average is 32.4nC, and the diode softness ratio is 0.39. As a result, high-frequency EMI inherent to Schottky rectifiers, which are frequently used at the output stage of Class D power amplifiers, is minimized.
Both diodes are supplied in the industry-standard DPAK TO-252 package.
Edward Ong, Product Marketing Manager at Power Integrations, stated, "The automotive audio system industry is seeking an alternative to Schottky diodes with abrupt reverse recovery characteristics used in Class D power amplifiers," and added, "Power Integrations' 200V Qspeed diodes are the solution for automotive audio amplifiers."
The LQ10N200CQ·LQ20N200CQ diodes are manufactured at IATF 16949 certified facilities. Pricing for 10,000-unit quantities is $0.60 and $0.74 respectively.
Technical support is available on the Power Integrations website.
