Littelfuse, Inc. today introduced two additions to its expanding line of second-generation, 650V, AEC-Q101-qualified silicon carbide (SiC) Schottky Diodes. Both series offer power electronics system designers a variety of performance advantages over traditional silicon-based devices, including negligible reverse recovery current, high surge capability, and a maximum operating junction temperature of 175°C. This makes them ideal for applications in which improved efficiency, reliability, and thermal management are desirable. The announcement was made in the Littelfuse booth (#253) at the Applied Power Electronics Conference & Exposition (APEC 2019) in Anaheim, California.
The LSIC2SD065DxxA Series SiC Schottky Diode is available with current ratings of 6A, 10A, or 16A in a TO‑263-2L package; the LSIC2SD065ExxCCA Series SiC Schottky Diode is available with current ratings of 12A, 16A, 20A, or 40A in a TO-247-3L package.
These SiC Schottky Diodes dissipate less energy and can operate at higher junction temperatures than alternative solutions such as standard silicon bipolar power diodes. They also require smaller heat sinks and support a smaller system footprint than those solutions. These advantages offer end-users the benefits of more compact, energy-efficient systems, and a potential lower total cost of ownership.
Typical applications for the new 650V SiC Schottky Diodes include:
- Electric vehicle (EV) charging stations
- Buck/boost stages in DC-DC converters
- Free-wheeling diodes in inverter stages
- High-frequency output rectification
- Power factor correction (PFC)
“These additions to our fast-growing 650V SiC Schottky Diode family allow us to offer a broader selection of current ratings and package designs suitable for a wider range of applications,” said Christophe Warin, Littelfuse Silicon Carbide Product Marketing Manager. “These new SiC Schottky Diodes enable a variety of design optimization opportunities, including increased power density, higher efficiency and potentially lower bill of materials costs.”
The new 650V SiC Schottky Diodes offer these key benefits:
- Available in TO‑263-2L and TO-247-3L packages for greater design flexibility.
- AEC-Q101-qualified diodes exhibit exceptional performance in demanding applications.
- Suitable for high-frequency power switching.
- Safe operation and ease of paralleling for reduced stress on the opposing switch.
- Larger design margin and relaxed thermal management requirements due to 175°C maximum operating junction temperature.

With Canadian manufacturing suffering from a growing labour shortage, the participation of industry in skills development is emerging as a vital component in hiring and retention.
The needs are stark: The Canadian Exporters and Manufacturers Association says almost 40% of its members have jobs they can’t fill. Five years from now, 60% expect to be short-staffed, especially when it comes to skilled trades. Statistics Canada forecasts the country’s labour force growth rate will remain below 0.2% for the rest of the decade, below replacement levels.
This growing shortage is affecting companies of all sizes. Already, some manufacturers acknowledge losing out on contracts because they can’t find the manpower to fulfill them.
In reality, the challenge is two-fold: to replenish and expand the workforce to help close the gap between the number of job seekers and vacancies through 2030 when the last baby boomers reach age 65, and ensure workers get opportunities throughout their careers to upgrade or add to their skillset as current technologies evolve and new ones emerge. Festo, through Festo Didactic, one of the world leading provider of equipment and solutions for technical education, intends to help Canada meet this challenge on both fronts. In essence, the approach Festo has always taken is that the learning never stops.

Emerson recently introduced the ASCO™ Series 209 proportional flow control valves, which offer the highest standards of precision, pressure ratings, flow characteristics and energy efficiency available in a purpose-built, compact architecture. With this combination of size and performance, Series 209 valves allow users to precisely regulate the flow of fluid in a wide range of devices that require exacting performance, like those found in the medical equipment, food and beverage, and heating, ventilation and air conditioning (HVAC) industries.
Accuracy, response time and repeatability are critical in high-precision flow control applications, such as controlling tool speed in dental chairs, the flow of steam in coffee makers, water flow in cooling systems and hydrogen flow in fuel cells. Series 209 valves have low hysteresis (less than or equal to 5%), excellent repeatability (less than or equal to 1%) and high sensitivity (less than or equal to 0.2%) that contribute to their precision.
