Schottky diodes current ratings expanded to 8A, 15A, and 20A
Littelfuse introduced four new series of 1200V silicon carbide (SiC) Schottky Diodes from its GEN2 product family, which was originally released in May 2017. The LSIC2SD120A08 Series, LSIC2SD120A15 Series, and LSIC2SD120A20 Series offer current ratings of 8A, 15A ,20A, respectively and are provided in the popular TO-220-2L package. Additionally, the LSIC2SD120C08 Series offers a current […]
Gauging progress in SiC MOSFET technology
A review of SiC MOSFET performance data shows these devices have improved dramatically in a short time. And improvements are likely to continue. Kevin M. Speer, PhD | Littelfuse, Inc., Sujit Banerjee, PhD | Monolith Semiconductor Inc. Insulated gate bipolar transistors (IGBTs), first commercialized in the early 1980s, revolutionized the power electronics industry. Today, silicon […]
Fuses for power protection, Part 2
Part 1 of this FAQ explained fuse basics. Although fuses are simple in principle, selecting the most suitable fuse for the application is more complicated than it may seem initially. Q: What are the key questions to ask when selecting a fuse? A: These are just a few of the considerations: What is the normal […]
SiC MOSFET provides ultra-fast switching in power electronics
The LSIC1MO120E0080 Series, with a voltage rating of 1.2 kV and ultra-low (80 mΩ) on-resistance, is optimized for high-frequency switching applications, providing a combination of ultra-low switching losses and ultra-fast switching speeds that’s unavailable with traditional power transistor solutions. When compared with silicon devices that have the same rating, the SiC MOSFET Series enables substantially […]
Six considerations for better circuit protection
In an electronic system where the power source can be connected the wrong way round, protection should be considered to prevent damage to the circuitry. Most electronic circuits don’t like the power supply being reversed. However, there are other eventualities you could protect your circuit or system from temperature, humidity, excess current or excess loading, […]
16-A SCR thyristors optimized for EV charging apps
Littelfuse, Inc.,introduced a series of 16A SCR (silicon-controlled rectifier) switching thyristors developed especially for use in electric vehicle on-board charge (EVOBC) applications. S8016xA Series SCR Switching Thyristors offer excellent AC handling capability and surge robustness, which allows them to handle Level 1 charging up to 16ARMS at 120V, and Level 2 charging up to 16ARMS at 240V at […]
