Qspeed Introduces Common Cathode Diode In TO-220 Package
Qspeed Semiconductor announced the full production release of its first common cathode product in an industry standard TO-220 package. The LQA20T300C, comprised of two 10A, 300V diodes in a common cathode configuration, is the latest addition to Qspeed’s portfolio of high performance power semiconductors.
The LQA20T300C is said to significantly reduce loss caused by diode recovery characteristics. Additionally, it is claimed that users will benefit from a dramatic reduction in voltage overshoot due to the soft recovery behavior of this diode. The new diode is said to enable lower component count and less PCB space and to result in lower bill-of-material costs. It is further stated that 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 what is described as 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 soft reverse recovery characteristics provide well behaved switching waveforms and lower power supply EMI.
The LQA20T300C diode is ROHS-compliant and is available now in production quantities.
