1700V SiC MOSFET optimized for high-frequency, high-efficiency applications
Littelfuse has announced their first 1700V SiC MOSFET, the LSIC1MO170E1000, expanding its portfolio of SiC MOSFET devices. An important addition to the Littelfuse SiC MOSFET product offering, the LSIC1MO170E1000 is a powerful addition to the company’s 1200V SiC MOSFETS and Schottky diodes already released. End-users will benefit from more compact, energy-efficient systems and also from a […]
Battery protection devices boost LiP and prismatic battery safety
Littelfuse Inc. had introduced the introduced MHP–TAC (Metal Hybrid PPTC – Thermal Activated Compact) Series Resettable Over-temperature Protection Devices, the latest addition to its line of battery min-breakers. These devices connect a PPTC (Polymeric Positive Temperature Coefficient) device in parallel with a bimetal protector (a resettable thermal cut-off device) to protect the high-capacity lithium-ion polymer […]
Eval kits help design silicon-carbide power circuits
There’s a lot of benefits that come with silicon carbide semiconductor devices. Increased power density, increased efficiency, lower form factor, simpler designs, simpler thermal management, are all examples of the benefits. But along with the things that silicon carbide enables, there’s also some side effects that make them hard to control, and if they’re not […]
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 […]
High-temp SCRs block up to 600 V, carry up to 40 A
The SJ Series High-Temperature SCR (Silicon-Controlled Rectifier) Switching Thyristors offers blocking voltages (VDRM) up to 600 V and current ratings from 4 to 40 A to support a wide range of applications. By offering a wider operating margin than earlier SCRs, they make it possible to tolerate insufficient cooling and higher inrush currents at startup. […]
