Aiming at vehicle traction, Infineon has put a pair of 3,300V 1,000A 1.9 mΩ silicon carbide trench mosfets into its 100 x 140 x 40mm ‘XHP 2’ module housing, calling the module FF2000UXTR33T2M1. This package is rated for 6kV testing, and achieves 2.6kV partial discharge extinction. Creepage is 40mm terminal to baseplate and 34mm between terminals. Clearance is 31 and ...

Onsemi has announced a 112 x 62mm power module for flying capacitor boost converters up to 1kV. It combines 1kV silicon IGBTs and 1.2kV silicon carbide diodes in the company’s F5BP package. Called NXH500B100H7F5SHG, it can handle continuous collector currents up to 210A (630A pulsed) (Tj = 175°C). Abs max power dissipation is 305W. To reducing stray inductance and thermal ...

Toshiba is aiming at air conditioners, air purifiers and pumps with an IGBT-based brush-less dc motor driver, suitable for sine-wave generation, in a ~13 x 33mm through-hole HDIP30 package. TPD4165K, as it will be know, can handle a maximum output of 3A, compared with 2A for the company’s earlier TPD4163K or TPD4164K. Absolute maximum input voltage has been raised to ...

Bourns has added six shunt resistor types its Riedon range, that it acquired in April last year when it bought Riedon Inc. Construction is with brass end-caps holding Manganin resistance elements. The latter has a temperature coefficient ~±15ppm/°C. Kelvin contacts are provided for the voltage output. Panel-mount RS resistors have values from 41.7μΩ to 20mΩ (±0.25%). There are sub-versions here: ...

It seems to be Ideal Diode Week at Electronics Weekly (here and here) as Diodes is also promoting one, this time an ideal diode that can cope with ±65V on its input and drops only 20mV when conducting. The automotive-compliant AP74700Q operates down to 3.2V (or 3.9V at start-up) to allow for cold cranking of a vehicle engine. Inside, a ...

Alpha and Omega has turned to 5 x 6mm LFPAK surface-mount packaging for a family of mosfets aimed at industrial, server power, solar, and telecommunication applications. Available at 40V, 60V, and 100V (see table) “AOS’s LFPAK enables higher board-level reliability due to gull-wing leads, which offer a ruggedised solution for board-level environmental stresses”, according to the company. “Gull-wing leads also ...

Nexperia has put an ideal diode, including its p-channel mosfet, and reverse polarity protection, in a 2.1 x 1.25 x 0.95mm TSSOP6 package. Called NID5100, it is aimed at industrial and consumer applications, and has an automotive-qualified cousin named NID5100-Q100. “NID5100 supports ‘OR-ing’ multiple power supplies while retaining reverse polarity protection and provides fast response time for smooth power transfer,” ...

Richardson RFPD, an Arrow Electronics company, has announced  a featured lineup of Ka-band, GaN-on-SiC MMIC power amplifiers from United Monolithic Semiconductors. Offered in die and plastic QFN packaging, the devices are available in a variety of power levels to support Ka-band SATCOM uplink and 5G FR2 bands n257, n258, n259 (partial), n260 and n261. UMS’ proprietary GH15 GaN process is ...

SemiQ has put 1,200V silicon carbide mosfet and Schottky diode half-bridges into standard ’62mm’ industrial power modules. There are four parts, each measuring 62 x 106.5 x 17mm (plus terminals): two mosfet hald-bridges and two Schottky half-bridges, aimed at new designs as well as efficiency-boosting replacements in legacy systems. 1.2kV 62mm power modules  Configuration Current Rds(on) GCMX003A120S7B1 SiC mosfet half-bridge ...

Bourns is offering IEC-grade surge protection for ac or dc power rails with four DIN rail mount device series. 1270 series AC surge protection to IEC/EN 61643-11 Class I + Class II / T1+T2 1280 series the same, plus a thermal disconnector “that eliminates the need for up-stream over-current protection”, said Bourns. 1430 series DC surge protection to IEC/EN 61643-31 ...
