Qspeed Introduces High-Performance Common Cathode Diode In Industry-Standard TO-220 Package

electronica 2008
SANTA CLARA, Calif.--(BUSINESS WIRE)--Qspeed Semiconductor announces the full production release of its first common cathode product in an industry standard TO-220 package. The LQA20T300C, comprised of two 10-amp, 300-volt diodes in a common cathode configuration, is the latest addition to Qspeed's portfolio of high performance power semiconductors.

The LQA20T300C significantly reduces loss caused by diode recovery characteristics. Additionally, users will benefit from a dramatic reduction in voltage overshoot due to the soft recovery behavior of this diode. Along with higher converter efficiency and reliability, this new diode enables lower component count and less PCB space resulting in lower bill-of-material costs. Power designers using the LQA20T300C are able to better meet new energy efficiency standards, while reducing the overall size, weight and cost of their end products.

"Our latest 300V diode continues Qspeed's commitment to providing our customers with leading edge performance at a great value point," said Syrus Ziai, Qspeed CEO. "Our customers tell us that they have been looking for ways to improve performance, especially efficiency, without relying on other solutions that are more expensive. When using Qspeed devices, designers are able to reduce overall costs and improve performance at the same time."

Typically used in output rectifiers or low voltage inverters for telecommunication and networking applications, the LQA20T300C uses proprietary Qspeed technology to achieve an extremely low reverse recovery charge (QRR), resulting in lower switching loss especially at high temperature and low peak voltage overshoot. In addition, the device's very soft reverse recovery characteristics provide well behaved switching waveforms and lower power supply EMI.

Availability and pricing

The LQA20T300C diode is ROHS-compliant and is available now in production quantities. Contact Qspeed's local sales offices or distributors for pricing and delivery.
