ROHM Launches Fast Recovery Diodes


SANTA CLARA, CA — ROHM Semiconductor has launched its fourth generation 650V fast recovery diodes (FRDs). The RFL/RFS series features low for- ward voltage and fast reverse recovery time, as well as ultra- low noise characteristics. The new devices are ideal


for industrial and consumer equipment that handle large amounts of power, such as air conditioners and EV charging stations. In recent years, more effective use of electricity is nec- essary to cope with the rise in global power consumption. This is especially true for


white goods and industrial equipment that handle large amounts of power, such as EV charging stations. These require not only high electrical efficien- cy, but also reducing workload for noise countermeasures in cir- cuit design. In response, ROHM developed diodes that combine low forward voltage for more effi- cient operation with fast TRR characteristics that provide less loss and ultra-low noise during switching off. Optimizing the device struc-


ture and materials allows the RFL/RFS Series to achieve the optimum balance of forward volt-

age and TRR, which are important characteristics for FRDs, but are in a trade-off relationship. The RFL series reduces forward volt- age by approximately 3.2% and


Fast recovery diodes.


TRR by about 8.3% over the con- ventional RFN series, while the high-speed RFS series decreases forward voltage by approximately 17.9% versus the conventional RFUH series. Both products con- tribute to higher power supply effi- ciency through optimal design based on circuit requirements. Furthermore, ultra-low noise diode recovery characteristics are achieved as they help to reduce both workload and components for noise.

Silicon Designs Releases New Reference Accelerometers


KIRKLAND, WA — Silicon Designs has launched its Model 2290 series of high-precision, sin- gle-axis MEMS DC calibration reference accelerometers.


Offered in four unique full-


scale acceleration ranges, the series offers a precise, reliable, and accurate means of determin- ing the sensitivity and frequency response characteristics of un - known MEMS DC accelerometers during end-to-end calibrations and related performance verifica- tions.


Within these applications,


the Model 2290 serves as the “Reference Standard,” either for performance specification com- parisons, or as an actual substi- tute for the working accelerome- ter.


Beyond such verifications,


the Series also supports a variety of zero-to-medium frequency instrumentation applications ranging from 2,000 Hz to DC, including both center of gravity acceleration measurements and equipment calibrations. The Model 2290 Series is


relatively insensitive to tempera- ture changes and gradients. Onboard voltage regulation and an internal voltage reference eliminate the need for precision


power supplies. Contact: Silicon Designs,
