Automotive-Qualified 200 V Qspeed Diodes from Power Integrations

Low-noise, high-efficiency, AEC-Q101 diodes solve thermal, EMI and distortion challenges in power amplifiers

Power IntegrationsPower Integrations announces that its 200 V Qspeed diodes – LQ10N200CQ and LQ20N200CQ – are now available with AEC-Q101 automotive qualification. Qspeed silicon diodes use merged-PIN technology to offer a unique balance of soft switching and low reverse recovery charge (Qrr). This results in low EMI and reduced output noise, which is especially important for in-vehicle audio systems.

The newly qualified 200 V diodes feature the industry’s lowest reverse recovery charge, typically 32.4 nC at Tof 125°C, and a diode softness ratio of 0.39. This minimizes high-frequency EMI inherent in the Schottky rectifiers often used in Class-D power amplifier output stages. Dual 10 A and 20 A common-cathode diodes are housed in the industry-standard, rugged DPAK TO-252 package.

Comments Edward Ong, product marketing manager at Power Integrations, “The automotive audio industry has been clamoring for an alternative to Schottky diodes with their ‘snappy’ reverse recovery, which causes ringing that generates EMI and noise in sensitive Class D amplifiers. Our automotive-qualified 200 V QSpeed diodes are the perfect solution for in-car audio amplification applications.”

The LQ10N200CQ and LQ20N200CQ diodes are produced in IATF 16949-certified facilities. Devices are available now; the LQ10N200CQ and LQ20N200CQ are priced at $0.60 and $0.74 respectively in 10,000 quantities.
