Diodes Provide Ultra-compact New High-voltage Rectifier
Diodes provide ultra-compact new high-voltage rectifier
Diodes Incorporated for power factor correction (Power Factor Correction, referred to as PFC) boost diode applications, the introduction of a new pair of the 600V DiodeStar rectifier to expand its DiodeStar product line. DSR6V600P5 and DSR6U600P5 Diodes proprietary the powerDI 5 package. The package has the characteristics of high thermal performance and thin, thinner, and thus can be used to design products and thermal efficiency is more significant.
The ultra-compact powerDI5 package from the board height of 1.1 mm thin, 52% of, DPak than the industry standard, and only DPak accounted for 43% of board space. In addition, the package is able to significantly reduce the thermal resistance (Rth j-c), therefore allowing higher-density design.
DSR6V600P5 for specialized applications in the continuous conduction mode (CCM) operation of the PFC circuit has been optimized, and have low reverse recovery time (Trr) characteristics and low reverse recovery charge (Qrr), and thus can boost diode anti- to restore the loss to a minimum. Similarly, DSR6U600P5 adjusted to the low forward voltage drop (VF) and low reverse recovery time, meet the requirements of the PFC circuit operating in critical conduction mode (BCM) required a compromise.
Typical soft DSR6V600P5 and DSR6U600P5 factor (Typical softness factor) of 0.7, to reduce the electrical noise caused by the soft-switching to reduce EMI shielding and buffer circuit, thus simplifying design and reducing component count.
These new high-voltage rectifier, especially suitable for high density of LED TV adapter switch mode power supplies (SMPS), can also be used as high-intensity gas discharge (High-intensity discharge, referred to as the ideal cycle diode HID) lighting applications choice.
TE PCFN power relay for solar PV inverter
The TE Connectivity TE relay department, has recently launched an innovative small-size power relay for modern photovoltaic system, photovoltaic inverter. PCFN power relay can be solar smoothly pass the power grid. In case of emergency, these devices will be based on today's safety regulations requirements, cut off the connection between the photovoltaic power generation system and the national grid.
PCFN power relays feature is only 200mW low to keep power 1.5W coil power, a 1.5mm contact gap and 26A rated current. PCFN solar relay to benefit from an electrode structure of an N / O contacts only need 510mm? PCB space. Its operating temperature range of -25 to 75 degrees Celsius (in 22A up to 85 degrees Celsius), fully RoHS compliant.
Cree claims new LED is going to fully replace the halogen
Cree has announced LED brightness, color quality and consistency of light to a new level, has taken a new step to the goal of a comprehensive alternative to the high-energy halogen light source. The new XLamp the MT-G LED has a higher brightness, unmatched light color quality and proven reliability of the lighting level.
The new MT-G LED brightness than the original 10% increase in warm white (3000K) conditions of 85 C up to 1670 lm luminous flux. In addition, the Cree are optimized for applications such as retail and restaurant lighting to provide high color rendering index (CRI) model MT-G LED, to meet these applications demand high color rendering index (CRI), as well as light and color consistency. These new capabilities to help clients expand their existing MT-G design and realization of new applications for traditional halogen light source can not be achieved.
USAI Lighting as one of the first applied to the lamp MT-G high color rendering index (CRI) LED lighting manufacturer, its award-winning NanoLED lighting solutions is to use the MT-G high color rendering index (CRI) LED. Cree MT-G NanoLED using proprietary optical technology to help designers to light and color quality, energy efficiency, flexibility and control integration, and various indoor lamps with dazzling beauty and practical functionality .
USAI Lighting CEO Bonnie Littman said: "We vowed to the pursuit of fine first-class quality of the light color is to ensure that our customers achieve the necessary conditions for high performance lighting solutions. Be able to provide customers with halogen-like light and color brightness and LED energy-efficient advantages, which will lead to a fundamental change in the market. "
Cree LED components market, senior director Mike Watson said: "The Cree MT-G LED is the flagship product that allows lighting OEMs truly free play real free play means for customers to order LED to provide multi-color Step 2 Step 4 of the choice of light color consistency. Career is the industry's first operating temperature of the LED device company file. these advantages and commercial components, Career bring the customer's advantage. "
IESNA LM-80 data show that the XLamp MT-G LED service life of more than 6,000 hours, and with higher brightness and color rendering index (CRI) of not less than 90. The MT-G LED color temperature range from 2700K to 5000K, all MT-G LED can supply according to Step 2 and Step 4 EasyWhite color temperature, forward voltage of 6V or 36V. The full range of the MT-G LED samples coming soon, and in accordance with the standard delivery time for mass production.
