富海微(HL)推出的6G03L是一款N沟道+P沟道复合MOSFET,采用SOT-23-6L小尺寸表面贴装封装,针对低电压(≤30V)、中小功率(≤2.5W)、高密度集成场景优化,兼具低导通损耗、快开关速度与宽温可靠性,适用于便携式电子、Type-C接口、小型负载驱动等多类应用。
6G03L的设计核心是**“小封装下的高集成与高效能”**,精准匹配消费电子、工业控制中对空间敏感、低功耗的需求:
该器件的电参数平衡了导通损耗、开关速度与可靠性,具体特性如下:
漏源击穿电压(Vdss)30V,覆盖常见低电压电源(3.7V锂电池、5V/9V/12V适配器);连续漏极电流(Id)9A,峰值电流能力可满足瞬时大电流需求(如TWS充电盒快充瞬间),无需额外并联器件,简化电路设计。
导通电阻(RDS(on))仅25mΩ@10V栅源电压,在SOT-23-6L封装中处于同类产品前列。以5A连续电流为例,导通损耗为I²×R=5²×0.025=0.625W,远低于最大耗散功率(Pd=2.5W),有效提升电池供电设备的续航能力。
栅极电荷量(Qg)[email protected],输入电容(Ciss)370pF、反向传输电容(Crss)40pF,开关速度快且驱动损耗低。例如,在1MHz开关频率下,驱动损耗约为36mW(计算:Qg×Vgs×f=7.2e-9C×5V×1e6Hz),适合开关电源、脉冲驱动等高频场景。
6G03L采用SOT-23-6L封装,尺寸仅约2.9mm×1.6mm×1.1mm,是同类复合MOSFET中体积最小的封装之一,可有效节省PCB空间,适配高密度集成设计(如TWS充电盒内部狭窄布局)。
此外,封装设计优化了热传导路径,结合2.5W的最大耗散功率,可稳定支撑小功率持续工作;宽温范围与高ESD防护(隐含工业级设计特性)进一步提升了器件在恶劣环境下的可靠性。
6G03L的N/P复合管可实现充电盒电池与Type-C接口的双向导通:充电时P沟道导通输入电流,放电时N沟道导通输出电流,小封装适配充电盒内部狭窄空间,低导通损耗延长电池续航。
在Type-C PD协议中,6G03L可作为VBUS路径的互补开关:当设备作为电源输出时N沟道导通,作为受电时P沟道导通,快开关速度适配PD协议的电压电流快速切换,避免浪涌干扰。
6G03L的9A电流能力可驱动多颗LED背光,低导通电阻减少压降(5V电源下5A电流压降仅0.125V),提升背光亮度一致性,宽温范围满足手表在户外高温下的稳定工作。
HL 6G03L是一款高集成度、小尺寸、高效能的复合MOSFET,核心优势在于:
该器件可有效降低系统成本与空间占用,是便携式电子、Type-C接口等低电压小功率场景的理想选择。
Request for quote
Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.
The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
