Hauppauge, NY, USA - Central Semiconductor has released the CMKTC825A temperature compensated (TC) Zener diode packaged in a space saving ULTRAmini SOT-363 surface mount case. It is claimed to be the world’s first TC Zener in a plastic surface mount package. Utilizing a new proprietary process technique, the CMKTC825A provides a highly stable reference voltage of 6.2V with only a small voltage change of less than 0.28 mV/°C over the temperature range of -55 °C to +100 °C. This is a considerable improvement compared to a standard Zener diode, which typically exhibits a voltage change of 500 mV over the same temperature range. In addition, the CMKTC825A occupies only 4.2 mm2 of circuit board space and has a low profile of 1.0mm. Designed for applications requiring extremely stable voltage reference over temperature, the CMKTC825A is ideal for use in high stability oscillators, digital volt/frequency meters, analog-to-digital converters, and precision DC power supplies. End products for this device include test equipment, consumer electronics, and industrial equipment. The CMKTC825A is available Bulk Packed or 3,000 pcs on 7" Tape & Reel. Prices for the CMKTC825A start at $0.36 each for 3,000 pcs on a 7" reel. Sample devices are available upon request. Central Semiconductor, Hauppauge, NY, USA. www.centralsemi.com
David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
