Diode arrays protect PHY chips from ESD and lightning damage
Littelfuse announced the first of a series of TVS Diode Arrays (SPA Diodes) designed to protect two lines of 10/100/1000BaseT Ethernet ports from damage due to sustained overcurrent and overvoltage. Through-package routing permits the SP4031 Series Hybrid Protection Module’s circuitry to protect an Ethernet PHY chip from damage due to events such as electrostatic discharge (ESD) […]
Thru-hole 650-V SiC power Schottky rectifiers handle up to 10 A
Through-hole SICR5650, SICR6650 and SICR10650 Series of 650-V silicon carbide (SiC) Power Schottky Rectifiers provides low total conduction losses and stable switching over temperature extremes. The single-diode SICR5650 and SICR6650 Schottky rectifiers support average rectified currents of 5 A and 6 A respectively, whereas the common cathode, dual-center-tapped SICR 10650 parts are provided with rectified […]
What are diodes? A quick refresher
A diode is a passive component made with semiconductor materials (a chip) that conducts current flowing in one direction but does not conduct current flowing in the opposite direction. The symbol for a diode (to the right in Figure 1) looks something like an arrow pointing in the direction of the forward current. Current flows […]
Trends in discrete power semiconductors
For many years the rumored demise of the discrete semiconductor has been thrown around, says Joe Beck from Central Semiconductor. Everything’s going to be integrated into an IC. It’s all going away. Not true. In fact, there’s more interest in discrete today than in the last 10 or 15 years, Beck says. When engineers try […]
SiC Schottky diodes shrink energy costs and space requirements
GEN2 Series 1,200-V, 3L TO-247 Schottky diodes and GEN2 Series 1,200-V, 2L TO-263 Schottky diodes dramatically reduce switching losses and allow for substantial increases in the efficiency and robustness of power electronics systems. High-efficiency benefits that SiC technologies enable offer multiple advantages to the designers of electric vehicle chargers, data center power supplies and renewable […]
SiC Schottky diodes target on-board charging of EVs and hybrids
At this year’s PCIM Europe trade fair in Nuremberg (June 5 to June 7) Infineon Technologies AG presents the first products of its automotive Silicon Carbide portfolio: the CoolSiC Schottky diode family is now ready for current and future on-board charger (OBC) applications in hybrid and electric vehicles. Infineon has designed the diodes specifically to […]
3-kW 3-phase PFC reference design uses SiC diodes and MOSFETs
Microsemi Corporation announced the availability of its new scalable 30-kilowatt (kW), three-phase Vienna power factor correction (PFC) topology reference design featuring its Silicon Carbide (SiC) diodes and MOSFETS. Developed in collaboration with North Carolina State University (NCSU), the scalable, user-friendly solution is ideally suited for fast electric vehicle (EV) charging and other high power automotive and industrial applications, providing customers with more efficient switching […]
