eGaN FETs now 15x smaller than silicon equivalents
Efficient Power Conversion Corp. advances the performance capability while lowering the cost of off-the-shelf gallium nitride transistors with the introduction of the EPC2045 (7 mΩ , 100 V) and the EPC2047 (10 mΩ , 200 V) eGaN FETs. Widening the performance/cost gap with equivalent silicon power transistors, the EPC2045, cuts the die size in […]
High power density IGBT modules target motor drives, inverters
Infineon Technologies AG is expanding its offering of 62 mm IGBT modules. The new power modules serve the growing demand for higher power density without increasing package size. This is realized by a larger chip area and an adapted DCB substrate in the proven 62 mm package. Typical applications for modules with 1200 V blocking […]

TVS Diode Arrays Safeguard HBLED Strings
Littelfuse, Inc. introduced a series of TVS Diode Arrays (SPA® Diodes) designed to protect each I/O pin of electronic equipment subject to destructive electrostatic discharges (ESD) or electrical fast transients (EFT). The new SP1064 Series TVS Diode Arrays are Zener diodes fabricated using a proprietary silicon-avalanche technology. These robust diodes can safely absorb repetitive ESD strikes […]
Automotive-compliant power ICs launching at Embedded World
Diodes Incorporated will be introducing a number of notable new products at Embedded World 2017 in Nuremberg, Germany, March 14-16. These include the industry’s first unidirectional 1800W automotive-compliant transient voltage suppressors; 40V and 60V dual, co-packaged enhancement mode MOSFETs that are also qualified for automotive applications; and, coming from its Pericom connectivity product line, the […]
Germanium could be the next high-efficiency transistor material
Germanium has always been an interesting material for use in semiconductors because it conducted well (superior hole mobility). Trouble is, germanium’s low band-gap energy of 0.66 eV has meant the material suffers from a lot of reverse junction current leakage. This gives it a reputation for high static power dissipation. Recently, a group of German […]
GaN Transistor SPICE models now on the Web
GaN Systems has experienced a surge in the number of customers designing and deploying power systems using their GaN transistors. Customers have recognized that GaN devices significantly improve power efficiency and power density. By using GaN transistors instead of legacy silicon components; customers are gaining a competitive advantage as they enter the market with 50 […]
