RV8L002SNHZG is ultra-compact MOSFET that delivers superior mounting reliability. RV8L002SNHZG is AEC-Q101 qualified, ensuring automotive-grade reliability and performance under extreme conditions. ROHM’s original Wettable Flank formation technology consistent solder quality even for bottom electrode type products. It is enabling automatic inspection machines to easily verify solder conditions after mounting. It enables the miniaturization of automotive components, such as ECU, ADAS camera modules, that demand high quality.
ROHM has released the ultra-compact AEC-Q101 qualified MOSFETs, RV8C010UN, RV8L002SN and BSS84X, best-in-class 1mm2 size that deliver automotive-grade reliability. The products are suitable for high-density applications such as ADAS and automotive ECUs.
The continuing electrification of vehicles in recent years has significantly increased the number of electronic and semiconductor components used per vehicle. Consequently, the need for a dramatic increase in component density has become even more important. For example, the average number of multilayer ceramic capacitors and semiconductor components installed in a single automotive ECU is expected to increase by 30%, from 186 in 2019 to 230 in 2025. At the same time, for high density automotive applications that demand greater miniaturization, studies are currently underway on bottom electrode packages that can achieve excellent heat dissipation in a compact form factor.
For automotive parts, automated optical inspection (AOI) is performed after mounting to ensure reliability, but with bottom electrode components the solder joint cannot be verified since the terminals are not visible, making it difficult to conduct visual inspection that meets automotive standards. ROHM has solved these issues with its original Wettable Flank technology that ensures an unprecedented side electrode height of 125μm in the 1.0mm × 1.0mm size, and leading to increased adoption by a number of vehicle manufacturers.
Extremely high solder mounting reliability is achieved during AOI in automotive systems that require high quality. In addition, the new bottom electrode package simultaneously provides both breakthrough miniaturization and high heat dissipation (which are normally in a trade-off relationship), making it ideal for ADAS and automotive ECUs featuring higher board densities.
In addition to MOSFETs, ROHM is committed to continuing to expand its product lineup of bipolar transistors and diodes.
With conventional bottom electrode packages, the sides of the lead frame cannot be plated, making it difficult to conduct AOI to verify the solder height required for automotive applications. In contrast, ROHM’s new MOSFETs leverage proprietary Wettable Flank technology to ensure a breakthrough side electrode height of 125μm in the 1.0mm × 1.0mm size. This enables stable toe fillet formation even with bottom electrode packages, allowing the solder condition to be verified by AOI after mounting.
ROHM’s new MOSFETs achieve the same performance as 2.9mm × 2.4mm packages (SOT-23 packages) but in the smaller 1.0 × 1.0mm package (DFN1010 packages), reducing mounting area by approx. 85%. In addition, adopting a high heat dissipation bottom electrode structure improves heat dissipation (which normally decreases with size) by up to 65% over SOT-23. As a result, the RV8C010UN, RV8L002SN, and BSS84X are ideal for automotive ECUs and ADAS that are seeing higher board densities following increasing performance.

AEC-Q101 Automotive Reliability Standard
AEC stands for Automotive Electronics Council, an organization (comprised of major automotive manufacturers and US electronic component makers) responsible for establishing reliability standards for automotive electronics. The Q101 standard is specifically intended for discrete semiconductor products (i.e. transistors, diodes).
Wettable Flank Formation Technology
A technique for plating the sides of the lead frame on bottom electrode packages such as QFN and DFN. This significantly improves solderability.
AOI (Automated Optical Inspection)
