Canadian gallium nitride transistor firm GaN Systems has announced top-side cooled power devices at the Applied Power Electronics Conference in North Carolina, which means they can be cooled with a normal heatsink or fan. “These are conventional techniques that are well-understood and familiar to design engineers who may be unfamiliar with using GaN devices or using them for the first ...

Belgium firm Cissoid has released a quad 80V wide temperature range diode package. Called CHT-ELARA, its isolated diodes operate across -55 to 225°C, handling up to 900mA at the highest temperature. They come in a hermetic 5×5.5mm TDFP16 ceramic package with a heat slug to achieve 11°C/W junction-to-case thermal resistance. Applications are expected in power rectification, for fly-back or forward ...

Eaton is sampling PowerStor XL60 Series supercapacitors which provide energy storage in backup power, engine starting, energy capture and re-use, peak power shaving and pulse power.

Toshiba has introduced eight single-phase BLDC motor pre-driver ICs for use in high-current cooling fan applications such as PC servers and home appliances, including fridges. The TC78B006 series reduces vibration and noise by using a digital-control-type sine wave drive.

At 0.6 x 0.35 x 0.35mm, AVX’s sub-millimeter E case 0201 TACmicrochip is the smallest ever tantalum capacitor range, claims the firm. 0.47μF at 6.3V is available with 0.01CV leakage. Small enough to be embedded in a PCB, AVX is pitching its product against multilayer ceramic capacitors on the grounds of inherent immunity to piezoelectric noise, stability, reliability, and temperature ...

X-REL Semiconductor has two power conversion ICs for demanding markets including aerospace, industrial, hybrid and electric vehicles, transportation, geothermal and oil and gas.

Infineon is shipping a new class of low saturation voltage VCE(sat) IGBTs specifically optimised for low switching frequencies ranging from 50Hz to 20kHz. It calls it the L5 family.

Vishay is aiming at zero voltage and soft switching applications by improving mosfet body diodes in a range of 600V power mosfets. The body diodes in SiHx28N60EF (28A) and SiHx33N60EF (33A) are fast, with low reverse recovery charge and on-resistance. Built on second-generation super-junction technology, the ‘EF’ series mosfets are designed to complement Vishay’s existing standard E Series components, expanding ...

Circuit protection firm Littelfuse is extending the reach of its Speed2Design programme through its design community website for engineers looking for support with circuit protection.

Microsemi’s latest silicon carbide (SiC) mosfets are on show at PCIM in Nuremberg, Germany this week. These are 1200V mosfets intended to be offer improved energy efficiency in high power applications include solutions for solar inverters, electric vehicles, welding and medical devices. The devices’ low gate resistance will minimise switching energy loss, even at high frequencies. According to Marc Vandenberg, general manager for Microsemi’s power products, ...
