Provides high-performance ICs and power devices, which are critical to the electrification of the automotive industry. ROHM's broad product lineup supports a variety of automotive solutions including infotainment/cluster, body ECU, EV, ADAS and powertrain.

In order to provide the quality and stable supply required by the automotive industry, ROHM employs a vertically integrated system - a key advantage - where all manufacturing stages are done in-house, from ingot drawing and photomask production to wafer processing, lead frame forming and packaging.

ROHM recently announced the addition of 10 new automotive-grade SiC MOSFETs. The SCT3xxxxxHR series allows ROHM to offer the industry's largest lineup of AEC-Q101 qualified SiC MOSFETs, providing high reliability for automotive onboard chargers and DC/DC converters.

circuit protection

ROHM offers an extensive line of TVS (Transient Voltage Suppressor) diodes, including ultra-low capacitance and high capacitance types in a variety of packages, to suit almost any need. Key features include leading TLP characteristics for ESD protection, high surge immunity with high clamping voltage for excellent surge resistance, and low VRWM for greater power savings. ROHM's RASMID technology also enables breakthrough miniaturization by providing unprecedented dimensional accuracy.

Discrete Semiconductor Products

ROHM's SiC Schottky Barrier Diodes feature low total capacitive charge (Qc), which reduces switching losses and enables high-speed switching operations. AEC-Q101-qualified types are also available for automotive PFC circuits and inverters, and they offer breakdown voltages of 600V, well beyond the limits of silicon SBDs.

In addition, high power Zener diodes are available that provide higher surge resistance than competing products, ensuring not only consumer equipment, but also automotive and industrial applications that require higher reliability.
