Infineon is aiming at 48V automotive applications with AUCN08S7N013, an 80V mosfet in a 5 x 6mm SSO8 that has a maximum on-resistance of 1.3mΩ at 25°C (Tj, 10Vgs, 88A Id). “48V applications including electric power steering, braking systems, power switches in zone architectures, battery management, e-fuse boxes, dc-dc and brushless dc motor drives,” it said. The mosfet is several ...

Shanghai-based WeEn Semiconductors unveiled 650V and 1,200V IGBTs with fast recovery anti-parallel diodes at PCIM in Nuremberg. “Based on fine trench gate field-stop technology, the IGBTs provide a more uniform electric field within the chip, support higher breakdown voltages and offer improved dynamic control,” according to the company. “A positive temperature coefficient simplifies parallel operation.” Ratings are 650V 75A, 1.2kV ...

Qorvo has picked depletion-mode (normally-on) silicon carbide JFET technology to build a 750V 4.3mΩ transistor for circuit breakers, and put it in a 10 x 12mm surface-mount TOLL package. “It was designed for circuit protection applications including solid-state circuit breakers, where low resistance, thermal performance and reliability are paramount,” according to the company. This “JFET can withstand high instantaneous junction ...

EPC is aiming at USB-C PD applications 50V 8.5mΩ GaN transistor with a 1.8mm2 footprint. EPC2057 measures 1.5 x 1.2mm and can handle 9.6A continuously (25°C) and 66A single 300µs pulses (25°C). With such a tiny package, thermals are important. According to the data sheet, junction-to-case thermal resistance is 2.3°C/W, then it is 7°C/W junction-to-board, 72.5°C/W junction to ambient on ...

A new selection of materials has allowed Rohm to add 5W rated current sensing resistors to its 2512 sized (6432 metric) PMR100 series of metal plate shunts, formerly rated at either 2 or 3W only. They are available in 0.5, 1 and 1.5mΩ. “Adopting a proprietary trimless structure suppresses the rise in temperature caused by localised current concentration. This allows ...

Navitas Semiconductor has made fast versions of its Gen-3 650 and 1,200V silicon carbide mosfets, branded ‘G3F’ and available in packages including D2PAK-7 to TO-247-4. “We’re pushing the boundaries of SiC, with up to 600kHz switching speeds said company v-p of technology Sid Sundaresan. One proposed application is in continuous-conduction-mode totem-pole power factor correction (CCM TPPFC) circuits up to 10kW in ...

Infineon has announced a flurry of new power products as a prelude to PCIM in Nuremberg next week, the latest of which is a family of 600V super-junction mosfets. Its eighth generation, “the devices combine the best features of the 600V CoolMOS 7 series and are the successors to the P7, PFD7, C7, CFD7, G7 and S7 product families”, according ...

Infineon has announced bi-directional GaN power transistors at 40, 650 and 850V, and a current sensing GaN transistor. There are two types of bi-directional transistor: The 650 and 850V devices are both normally-off monolithic gate-injection transistors with four operational modes via two separate gates and a substrate terminal, to deliver what the company calls ‘independent isolated control’. “They utilize the ...

Infineon is putting 650V silicon carbide mosfet die into two packages with SO-type footprints: a thin (1.5mm) bottom-cooled 8 x 8mm leadless TO (TOLL – TO leadless), and 9.8 x 15 x 2.3mm 16 leg SO version with top-side cooling (‘TOLT’ package) (see photo). Die with typical on-resistances of 20, 40, 50 or 60mΩ are available in either package, and ...

Alpha and Omega Semiconductor has designed an asymmetrical half-bridge mosfet pair in a 3.5 x 5mm DFN package for high-current dc-dc converters. Rated at 30V, AONG36322 has a 83A <4.5mΩ high-side transistor and a 163mA <1.3mΩ low-side transistor with 10V gate drive. On-resistances rise to <8mΩ and <1.75mΩ respectively with 4.5V gate drive. “AONG36322 [is] ideal for a new generation ...
