High-efficiency, fast-switching GaN FET earns AEC-Q101 qualification
Transphorm Inc. announced that its second generation, JEDEC-qualified high voltage gallium nitride (GaN) technology is now the industry’s first GaN solution to earn automotive qualification—having passed the Automotive Electronics Council’s AEC-Q101 stress tests for automotive-grade discrete semiconductors. Transphorm’s automotive GaN FET, the TPH3205WSBQA, offers an on-resistance of 49 milliOhms (mΩ) in an industry standard TO-247 […]
2.0A, 2.5A and 3.0A power switches optimized for USB port protection
Featuring an ultra-low on resistance to reduce power losses, the AP22811 and AP22804/AP22814 power switches introduced by Diodes Incorporated are optimized for universal serial bus (USB) and other hot-swap applications. Supporting load currents of 2.0A, 2.5A and 3.0A, respectively, this family of devices protects USB ports against over-current, short-circuit and over-temperature conditions and prevents system […]
Tiny 2.6-A BDC motor driver targets portable, battery-powered IoT devices
The STSPIN250 single-chip 2.6A driver for brushed DC motors extends STMicroelectronics’ family of miniature, low-voltage, energy-efficient drivers for battery-powered portable and wearable applications. The driver integrates a full power-MOSFET bridge and fixed off-time PWM current controller in a tiny 3mm x 3mm package that saves space in portable equipment. The low on-resistance of the power […]

Packaged in the thermally efficient PowerDI®5 package, […]
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 […]
Integrated power switches handle 1 to 4 A
Silego Technology announced today an extension of its performance-driven GFET3 Integrated Power Switch (IPS) portfolio. Addressing extremely PCB-space-constrained, high-performance applications in tablet PC, smartphones and fitness band markets, these three new WLCSP products cover high-side power control applications from 1 A to 4 A. For smartphone and fitness band applications, the 0.64 mm2 (0.8 mm x […]
Power modules lessen the load on internal combustion engines
Integrated smart power modules will run mechanical loads that would otherwise sap fuel mileage. THOMAS YIM | ON SEMICONDUCTOR GOVERNMENT REGULATIONS are stimulating demands for more economical vehicles that produce not just fewer NOx pollutants, but also less CO2. Vehicle tax policies currently favor less polluting models, and car makers must cope with new legislation […]
