SiC JFETs enhance system reliability under stress

1 week ago | edn.com | Susan Nordyk

CoolSiC JFETs from Infineon provide low conduction losses and robust turn-off behavior for solid-state protection and power distribution. Their strong short-circuit capability, linear-mode thermal stability, and accurate overvoltage control make them well-suited for solid-state circuit breakers, automotive battery disconnect switches, and industrial safety relays. The bulk-channel optimized JFETs offer RDS(on) values as low as 1.5 mΩ for 750 V devices and 2.3 mΩ for 1200 V variants.
SiC MOSFETs reinforce system longevity

With a built-in MEMS resonator, SiTime’s Symphonic SiT30100 mobile clock generator replaces up to four discrete timing devices. It provides accurate clock signals for 5G and GNSS chipsets in mobile and IoT devices such as smartphones, tablets, laptops, and asset trackers. An integrated temperature sensor feeds precise data to compensation algorithms, helping maintain clock stability.
3D ultrasonic sensor improves robot safety

1 week ago | edn.com | Susan Nordyk

Sonair’s 3D ultrasonic sensor uses acoustic detection and ranging (ADAR) to enable 360° obstacle detection up to 5 meters. Each ADAR sensor offers a 180×180° field of view, allowing autonomous mobile robots (AMRs) to safely navigate around people and objects. The beamforming technology behind ADAR—used in SONAR, RADAR, and medical imaging—has been under development at Norway’s MiNaLab research center for over 20 years and is now adapted for in-air ultrasonic sensing.
High-power laser diode targets bio diagnostics

1 week ago | edn.com | Susan Nordyk

Designed for life science applications, the PLT5 488HB_EP cyan laser diode from ams OSRAM delivers 300 mW of output power at 488 nm. It offers five times the optical output and over 40% higher efficiency than its predecessor—key for DNA sequencing, flow cytometry, and other diagnostic tasks. According to the company, cyan light effectively stimulates fluorescent dyes in diagnostic devices like flow cytometers and blood testing equipment.
Gate driver enables flexible EV inverter design

The STGAP4S galvanically isolated automotive gate driver from ST connects to an external MOSFET-based push-pull buffer to scale gate current capability. This architecture enables control of inverters with varying power ratings, including high-power designs with multiple parallel power switches. The STGAP4S can deliver gate drive currents in the tens of amperes using small external MOSFETs and handles operating voltages up to 1200 V.
Rectifiers meet automotive quality standards

Taiwan Semiconductor offers two series of high-voltage rectifiers, both manufactured to AEC-Q101 standards for reliable automotive performance. The fast-recovery HS1Q series provides a repetitive peak reverse voltage of 1200 V, a forward current of 1 A, and a reverse recovery time of 75 ns. The standard-recovery SxY series includes 1600-V rectifiers with forward currents of 1 A (S1Y) and 2 A (S2Y). Both series are also available in commercial-grade versions.
SiC MOSFETs trim on-resistance and gate losses

2 weeks ago | edn.com | Susan Nordyk

Infineon’s 750-V CoolSiC G2 MOSFETs enhance system efficiency and power density in automotive and industrial power conversion. The second-generation G2 technology provides typical on-resistance values up to 60 mΩ, supporting a wide range of applications such as onboard chargers, DC/DC converters, xEV auxiliaries, and solar inverters. A best-in-class RDS(on) of 4 mΩ is available in the top-side cooled Q-DPAK package, which delivers strong thermal performance and reliability.
Nexperia shrinks Schottky footprint with CFP2-HP

2 weeks ago | edn.com | Susan Nordyk

Sixteen planar Schottky diodes for automotive and industrial use are now available from Nexperia in compact CFP2-HP packages. These clip-bonded FlatPower (CFP) packages offer a smaller, high-performance alternative to legacy SMA, SMB, and SMC packages, delivering improved heat dissipation while maintaining a compact 3.45 mm² footprint—particularly in space-constrained automotive designs.
