Vishay has introduced a 5A 30V solid-state relay in a SOP-4 surface-mount package. VOR1003M4T is an industrial-grade relay with a 1 Form A (single-pole normally-open) contact. On the output side there are back-to-back mosfets allowing ac or dc to be switched. Typical output-side figures are: 0.7Ω Rds(on), 500μs Ton, 100μsToff and <1μA leakage. These switching times are with 10mA drive ...

100V SOP-4 solid-state relay with AEC-Q102 qualification
Vishay has introduced a 1 Form A solid-state relay with AEC-Q102 qualification and a 100V load voltage, claiming it to be industry’s first. Packaged in low-profile SOP-4 package (5 x 7 x 2.2mm), VORA1010M4 typically turns on and off in 100μs, and operates up to +125°C. “The fast turn-off time is a result of its integrated turn-off circuit, while its ...
Solid-state relay has high dV/dt and high blocking voltage
Excel Cell Electronics (ECE) ESR5 series of solid-state relays are available with or without LED Indicators, with ac or dc control inputs, and, separately, with ac or dc-type outputs. “Characteristics include its zero voltage turn-on, zero voltage turn-off to minimise EMI and RFI, and output snubber circuit protection. It also has a high surge rating to allow lamp and motor ...
Solid electrolyte forms in place for better Li batteries
A solid electrolyte that only forms once its liquid precursors are in intimate contact with electrode material is mooted as a step towards all-solid lithium batteries by Cornell University. Intimate contact – inherent with liquid electrolytes – is needed to achieve high lithium ion throughput and low series resistance. “The key insight is the introduction of molecules capable of initiating ...
Reactive buys Arraid
Reactive Group, the Reading data storage and networking specialist , has bought Arraid, the Phoenix manufacturer of replacement data storage products for ageing disk, tape and floppy drives on legacy computer systems. Reactive will revamp Arraid’s replacement drives with SSD technology. “The acquisition of Arraid significantly expands our existing ‘Through Life Support’ capabilities with regard to ageing, obsolete and end-of-life ...
Solid-state DIN relay has integrated heatsink
Available from Switchtec for industrial high speed switching applications, Kudom’s KSV series solid state relays are DIN rail mountable and come with an integral heatsink, DIN rail mounts and surface mount clip. “A single part number specifies and purchases a correctly rated and fully kitted out relay ready to install and use,” said Switchtec, which claims 1ms operating time for ...
The future of microwave cooking is solid-state
Microwave cookers are about to change as magnetrons are replaced by more flexible solid-state energy sources – or so says RF power transistor maker Ampleon, which was part of NXP until last year. It’s all about cooking speed and cooking control. The venerable magnetron does a fine job delivering microwave power, many would say, and manufacturers have making them down ...
When Nobody Wanted CMOS
Gerald Herzog, who pioneered CMOS development at RCA which made RCA the leading exponent of CMOS for many years, recalls the trouble he had persuading RCA management to make CMOS devices.
ISSCC – Solid state circuits take centre stage
The International Solid State Circuits Conference is an important gathering for the electronic engineering industry, regarding systems-on-a-chip and solid-state circuits.
Texas Instruments Launches Epitaxial Transistors.
‘The introduction on of the first commercially available epitaxial transistor was announced last week by Texas Instruments.’ So, 50 years ago, starts a story in the May 24th 1961 edition of Electronics Weekly.
