WeEn Semiconductors has unveiled a pair of 2,000V rectifiers in TO247 packaging, one rated at 90A and the other at 60A. They are the WND90P20W and the WND60P20W respectively. “These devices are engineered to mitigate voltage spikes in electric vehicle charging loads,” according to the company, which went on to emphasise their forward voltage drop and thermal resistance. Digging into ...
Mikroe has added a smart 85V 10A stepper motor driver to its range of interchangeable ‘Click’ boards. Called Power Step 2 Click, the board “is based on the powerSTEP01, a 1/128 microstepping controller from STMicroelectronics that integrates eight n-channel mosfets with ultra-low Rds(on)”, according to Mikroe. “It features a 5MHz SPI interface, multiple safety protections, and additional control pins for ...
SemiQ is aiming at solar inverters with 1,200V SiC mosfets that are avalanche tested to 800mJ, some co-packaged with silicon carbide Schottky diodes – all have intrinsic reverse diodes. There are four devices: GCMS008C120S1-E1 8.4mΩ with Schottky GCMX008C120S1-E1 8.4mΩ GCMS016C120S1-E1 16.5mΩ with Schottky GCMX016C120S1-E1 16.5mΩ The resistance figures here are the channel on-resistance. In addition, two more are avalanche tested ...
Littelfuse has introduced a 200V half-bridge mosfet and IGBT driver with integrated cross-conduction protection logic, said the company. IXD2012NTR, as it will be known, is designed to drive n-channel mosfet gates that need between 10 and 20V, and can supply a minimum of 1.4A pull-up and 1.8A pull-down (both into short-circuits) from either output. Typical figures are 1.9 and 2.3A ...
SemiQ has released three 1.2kV three-phase silicon carbide mosfet bridges in 62.8 x 33.8 x 15mm press-fit six-pack modules. 20mΩ 263W GCMX020A120B2T1P 40mΩ 160W GCMX040A120B2T1P 80mΩ 103W GCMX080A120B2T1P Power in this list is the maximum allowable when the case is at 25°C and the junctions are at their maximum of 175°C. Each is tested to over 1,350V with 100% wafer-level ...
Diodes has introduced some 650V SiC Schottky diodes, rated at 4, 6, 8, 10 or 12A. Called the DSCxxA065LP series, they come in a 8 x 8 x 1mm T-DFN8080-4 package. The company claims a leading Qc x Vf figure-of-merit, but does not include the numbers in its data sheets, so Electronics Weekly unleashed its calculator to find typical 25°C ...
For hard-switched power topologies, Infineon is planning a 100V GaN transistors with a integrated Schottky diode. “Due to the lack of body diode in hard-switching applications, GaN-based topologies may incur higher power losses due to the larger effective body diode voltage of GaN devices,” according to the company, which explained: “GaN transistor reverse conduction voltage is dependent on the threshold ...
Melexis has created a 32 x 24 pixel far-infra-red sensor array that can photograph the temperature of objects at between -40 and +260°C. Dubbed MLX90642, it comes in a 9.3mm diameter four-lead TO39 through-hole package in two versions: a squat (5.7mm tall) 110° x 75° wide-view type (BCA suffix) and a taller (11.9mm) 45° x 35° narrow-view version (BCB). The ...
Rohm has created three n-channel power mosfets in 5 x 6mm DFN packaging. RS7E200BG is a 30V mosfet optimised for both secondary-side ac-dc conversion and hot-swap controllers in 12V enterprise server power supplies. RS7N200BH is an 80V mosfet optimised for secondary ac-dc conversion in 48V server power supplies, as is RS7N160BH. “The DFN5060-8S package increases the internal die size area ...
Microchip has introduced a 32 logic elements programmable logic array into a microcontroller. Each logic element can simulate AND, OR, NAND or NOR gate, a buffer or inverting buffer, a D or JK flip-flop, multiplexers or a four-input look-up table. It is called the CLB (configurable logic block) and it based on an earlier simpler Microchip peripheral called the CLC ...
