KYOTO, Japan<\/span><\/span>, Aug. 21, 2025<\/span><\/span> \/PRNewswire\/ —\u00a0ROHM Co., Ltd. has launched the AW2K21, a 30V\u00a0N-channel MOSFET in a common-source configuration that delivers an industry-best* ON-resistance of 2.0 milliohms (typ.) in a compact 2.0mm x 2.0mm WLCSP package. This innovation addresses the growing demand for fast charging in compact devices like smartphones and wearables, which require bidirectional protection and high-current handling.<\/p>\n

Traditional solutions often rely on two large MOSFETs to meet stringent specs — 20A current rating, 28-30V breakdown voltage, and less than or equal to 5 milliohms ON-resistance — resulting in increased board space and complexity. ROHM’s AW2K21 overcomes these limitations by integrating two MOSFETs into a single ultra-compact package, enabling bidirectional protection with reduced footprint and power loss.<\/p>\n

The proprietary structure enhances cell density and places the drain terminal on the top surface, unlike conventional vertical trench MOSFETs. This allows for a higher chip-to-package area ratio, minimizing ON-resistance per unit area and supporting high-current operation. Compared to standard 3.3mm x 3.3mm MOSFETs, the AW2K21 reduces footprint and ON-resistance by approximately 81% and 33%, respectively. It also outperforms similarly sized GaN HEMTs with up to 50% lower ON-resistance.<\/p>\n

Ideal for power supply and charging circuits, the AW2K21 also excels in load switch applications as a unidirectional protection MOSFET. ROHM is further advancing miniaturization with a 1.2mm x 1.2mm model currently under development.<\/p>\n

ROHM continues to drive energy efficiency and miniaturization in electronics, contributing to a more sustainable society through high-performance semiconductor solutions.<\/p>\n
