Power Integrations introduces automotive-grade 200 V Qspeed diodes to greatly enhance sound

by:MOSO     2019-12-30

deep in high pressure integrated circuit high energy efficiency Power conversion field of well-known the Company Power Integrations (Nasdaq stock code: POWI) Recently announced its 200 V Qspeed™Diode- LQ10N200CQ and LQ20N200CQ-Now passed AEC-Q101 automotive grade certification. Qspeed silicon diode uses hybrid PIN technology to recover charge in soft switching and low reverse (Qrr)Provide a unique balance. This feature helps reduce EMI and output noise, which is especially important for car audio systems.

The newly certified 200 V diode has the lowest reverse recovery charge in the industry at 125C tj is usually 32. 4 nC, and the softness ratio of the diode is 0. 39. This feature can minimize high frequency EMI, which is an inherent feature of Schottky rectifier commonly used in class D power amplifier output stage. The 10 A and 20 A common cathode dual diodes are made of durable dpak-252 package.

Edward Ong, product marketing manager of Power Integrations, said: The car audio industry has been strongly demanding to replace Schottky diodes with a diode with fast reverse recovery characteristics, however, this feature causes ringing, resulting in EMI and noise in sensitive Class D amplifiers. Our certified 200 V QSpeed diode is the perfect solution for car audio amplification applications.

LQ10N200CQ and LQ20N200CQ diodes are produced in factories certified by IATF 16949 standard. LQ10N200CQ and LQ20N200CQ are now available. The unit price based on the order quantity of 10,000 pieces is 0. 60 dollars and 0. 74 dollars.
