Packing twin MOSFETs right into a tiny 2.0mm × 2.0mm footprint, it delivers ultra-low 2.0mΩ ON-resistance—ideally suited for fast-charging smartphones, wearables, and compact electronics.
ROHM has launched the AW2K21, a 30V N-channel MOSFET in a 2.0mm × 2.0mm package deal—delivering a class-leading ON-resistance of simply 2.0mΩ (typ.). Designed for power-hungry, fast-charging units like smartphones and wearables, this compact answer is optimized for bidirectional safety and excessive present move, tackling trendy design challenges in client electronics.
The important thing options of this are:
- 81% smaller footprint vs. standard 3.3mm × 3.3mm MOSFETs
- 33% decrease ON-resistance in comparison with commonplace options
- As much as 50% decrease ON-resistance than equally sized GaN HEMTs
- Improved thermal efficiency and lowered energy loss
- Sooner, extra dependable charging in ultra-compact units
Historically, assembly fast-charging calls for required two cumbersome low ON-resistance MOSFETs, taking over priceless board area. The corporate solves this with a dual-MOSFET common-source configuration, enabling a single system to deal with bidirectional safety in charging and energy provide circuits. Its proprietary vertical trench construction—with a top-side drain and WLCSP packaging—maximizes chip-to-package space and reduces ON-resistance per unit space.
With a 20A present ranking, 28V–30V breakdown tolerance, and minimal resistance, it’s tailor-made for at this time’s fast-charging, space-constrained functions—from smartphones, tablets, and laptops to VR headsets, drones, and moveable printers. It additionally serves as an ultra-efficient unidirectional safety MOSFET in load change roles, setting new requirements in miniaturization and efficiency.
Trying forward, the corporate is already pushing additional, creating a 1.2mm × 1.2mm variant to fulfill next-gen miniaturization calls for. It’s obtainable now at $3.5 per unit (pattern pricing, tax excluded), marking a brand new benchmark in compact energy system design for a sustainable electronics future.
