HL 3400是富海微(HL)推出的一款低电压N沟道增强型MOSFET,专为小尺寸、低功耗、高频切换场景设计,兼具高电流能力与小封装优势,适配多种便携及工业级应用需求。
HL 3400针对30V以下低压系统优化,核心优势集中在以下三点:
HL 3400的电气参数精准匹配低压应用需求,核心参数如下:
导通电阻(RDS(on))是低压MOSFET的核心指标:在2.5V栅源电压(Vgs)、3A漏极电流下,RDS(on)仅36mΩ,相比同类产品具有更低的导通损耗,尤其适合电池供电的便携设备(如手机、智能手环的电源管理)。
SOT23封装体积小巧,引脚间距合理,便于自动贴装(SMT),适合批量生产;同时封装材料耐温性好,与宽温工作范围匹配,长期可靠性高。
-55℃至+150℃的工作温度范围,覆盖了工业级设备(如户外传感器、车载小模块)的极端环境需求,避免低温下性能下降或高温下损坏。
栅极内置ESD防护(常规MOSFET标准设计),可承受±2kV人体模型(HBM)静电冲击,降低生产与使用中的损坏风险。
HL 3400的参数特性使其适配以下场景:
为确保HL 3400稳定工作,需注意以下要点:
综上,HL 3400是一款高性价比的低压N沟道MOSFET,兼具小封装、低损耗、宽温等优势,可广泛应用于便携、工业、消费电子等领域,是低压系统设计的理想选择。

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.
