It has been announced that Littelfuse has introduced two series of bidirectional TVS Diode Arrays (SPA Diodes) designed to protect ultra high speed consumer electronics interfaces from damaging electrostatic discharge (ESD) in applications where PCB layout is especially challenging.
SiC schottky diodes with current ratings from 6-40A at APEC 2019
Littelfuse has introduced two additions to its expanding line of second-generation, 650V, AEC-Q101-qualified SiC Schottky Diodes. Both series offer power electronics system designers a variety of performance advantages over traditional silicon-based devices, including negligible reverse recovery current, high surge capability, and a maximum operating junction temperature of 175°C. This makes them suitable for applications in which improv...
Protection thyristor safeguards CVBS signal lines
It has been announced that Littelfuse has launched the PxxxxS4xLRP Series SIDACtor Protection Thyristor, a robust solution for protecting Composite Video Blanking Sync (CVBS) signal lines and ports from damaging overvoltage transients. The combination of six volt operating voltage and 100A 5/310µs surge peak current capability and a low junction capacitance rating make the P0080S4BLRP suited for protecting a wide range of equipment needs da...
SiC MOSFETs respond to need for fast charge
Understanding the structure of SiC MOSFETs helps engineers develop appropriate systems, say Levi Gant, Littelfuse and Sujit Banerjee, Monolith Semiconductor
Hybrid protection module guards from sustained overcurrents
The first of a series of bidirectional TVS Diode Arrays (SPA Diodes) designed to protect high-end consumer and wearable electronics from damaging ESD-generating events have been introduced by Littelfuse. The SP1333-01UTG, the first TVS Diode Array in the SP1333 Series, with a breakdown voltage 3.3V, incorporates back-to-back diodes fabricated using a proprietary silicon avalanche technology.
SIP relay has 4000V isolation for high performance switching
Offering twice the load current of its most popular power relay, the CPC1984Y is a 600V, normally open power SIP relay, rated for up to 1A DC/1A rms continuous load current.
SiC MOSFET enables high frequency power control applications
Expanding its portfolio of SiC MOSFET devices, Littelfuse has introduced its first 1,700V SiC MOSFET, the LSIC1MO170E1000. An important addition to the Littelfuse SiC MOSFET product offering, the LSIC1MO170E1000 is a powerful addition to the company’s 1,200V SiC MOSFETS and Schottky diodes already released. End-users will benefit from more compact, energy-efficient systems and also from a potential lower total cost of ownersh...
Over-temperature protection devices boost battery safety
Littelfuse has 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 (LiP) and prismatic battery cells used in mobi...
TRIAC helps designers improve thermal management
Littelfuse has introduced six series of high-temperature sensitive, standard and alternistor TRIAC, designed for use as semiconductor switches in appliances and equipment powered by line AC voltages up to 220VRMS. Available in compact, surface-mount packages, these components are the industry’s first TRIAC with such a high maximum temperature that are available in ratings of 4A, 6A, and 8A.
SiC Schottky diodes shrink energy costs and space requirements
Littelfuse has introduced an expanded portfolio of silicon carbide (SiC) power semiconductor devices with the addition of five GEN2 Series 1200V, 3L TO-247 Schottky Diodes and three GEN2 Series 1200V, 2L TO-263 Schottky Diodes. When compared with silicon devices, GEN2 SiC Schottky Diodes reduce switching losses and allow for increases in the efficiency and robustness of power electronics systems. The product introduction was made during the PCIM ...
Robust clip-attach package design supports mechanical durability
Littelfuse has upgraded its switching thyristor line with the introduction of the SJ Series High Temperature SCR (Silicon-Controlled Rectifier) Switching Thyristors. This new series offers circuit designers blocking voltages (VDRM) up to 600V and current ratings from 4-40A to support a wide range of applications. By offering designers a wider operating margin than earlier SCRs, they make it possible to tolerate insufficient cooling and highe...
Automotive-qualified fuses save space on crowded boards
With interrupting current ratings up to 1,500A, a new series of surface-mount fuses has been introduced by Littlefuse. The series is optimised for use in high voltage automotive applications up to 350VAC or 450/500VDC. NANO2 885 Series Fuse is designed to protect electric vehicles against severe fault/short-circuit currents, ensuring reliability in harsh environments.
