GaN half-bridge power ICs enable megahertz-range switching frequencies
Navitas Semiconductor announced the industry’s first GaNSense half-bridge power ICs. These half-bridge ICs enable a new level of MHz switching frequencies while dramatically reducing the system cost and complexity compared to existing discrete solutions. GaNSense half-bridge power ICs integrate two GaN FETs with drive, control, sensing, autonomous protection, and level-shift isolation, to create a fundamental […]
High-current SMD shunt resistors sport 0.1 milliohm resistance
Modern electric power systems continue to push the power envelope. Power electronics for electric vehicles often use a high-power low resistance shunt resistor which can be expensive and difficult to find. Stackpole’s HCS high current SMD shunt resistors are now available in a 0.1 milliohm resistance value in a 10W, 5930 chip size. The HCS has an […]
High-power sense resistors feature high temperature stability
For current sensing applications requiring high efficiency, low resistance values are required. Typically, high power sense resistors are very large and have TCR in the 200 to 400 ppm range. Stackpole’s HCSM2818 is rated at 5 watts and now provides a 2 milliohm resistance value with a TCR of 100 ppm. This ensures the HCSM2818 is stable at […]
High-power fuses meet UL 248-13 standard for high interrupt current rating
Bourns, Inc. announced the expansion of the Company’s POWrFuse High-Power Fuse product family. The two new POWrFuse models PF-F and PF-M series are high power rating industrial fuse links specially designed to meet the UL 248-13 semiconductor (aR) standard. These high-power fuses are excellent solutions to help protect sensitive power semiconductor devices against overcurrent events in a […]
Rad-hard GaN FET comes in small 6.56-mm-sq footprint
EPC announces the introduction of the EPC7004 radiation-hardened GaN FET. The EPC7004 is a 100 V, 7 mΩ, 160 APulsed, rad-hard GaN FET in a small 6.56 mm2 footprint.
