Why it’s tough to characterize SiC power MOSFETs
Switching transients and parasitics can combine to thwart the accurate measurement of important MOSFET operating parameters. Levi Gant, Xuning Zhang, Ph.D., Littelfuse, Inc. Silicon carbide (SiC) power MOSFETs get a lot of attention because they can switch fast while maintaining high blocking voltages. But their superior switching qualities also have potential drawbacks. Parasitic inductances caused […]
650 V SiC Schottky diodes are AEC-Q101-qualified
Littelfuse, Inc. introduced two second-generation series of 650V, AEC-Q101-qualified silicon carbide (SiC) Schottky Diodes. The LSIC2SD065CxxA and LSIC2SD065AxxA Series SiC Schottky Diodes are available with a choice of current ratings (6A, 8A, 10A, 16A or 20A). They offer power electronics system designers a variety of performance advantages, including negligible reverse recovery current, high surge capability, and […]
Low capacitance diode arrays extends breakdown voltage range from 3.3V to 36V
Littelfuse, Inc. today introduced 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. 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. This back-to-back configuration […]
Power SIP relay rated for up to 1A DC/1Arms continuous current load
IXYS Integrated Circuits Division, now part of Littelfuse, Inc., hasintroduced the CPC1984Y, a 600V, Normally Open Power SIP Relay, rated for up to 1A DC/1Arms continuous load current, twice the load current of the company’s most popular power relay. This high-reliability device uses optically coupled MOSFET technology to provide 4000Vrms of input-to-output isolation. In fact, […]
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) […]

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 […]
