WNM3008-3/TR是韦尔半导体(WILLSEMI)推出的低压N沟道增强型MOSFET,采用SOT-23小型表面贴装封装,核心面向5V/12V低压小功率电路的开关控制需求,覆盖便携电子、电源管理、电池保护等多个细分场景。其参数设计匹配“小体积、高效率、宽温可靠”的低压应用痛点,是替代传统晶体管或同类MOSFET的高性价比选择。
最大漏源电压(Vdss)为30V,满足多数低压系统(如5V、12V)的耐压需求;连续漏极电流(Id)可达3.1A(需结合散热条件),峰值电流能力进一步提升,可覆盖微型电机、LED阵列等小功率负载的瞬时需求。
导通电阻(RDS(on))低至62mΩ(Vgs=10V时),在同电压等级、同封装MOSFET中处于优势水平。低导通电阻直接降低导通状态下的功率损耗(P=I²×R),尤其适合持续负载场景(如电源开关),减少发热并提升系统效率。
最大耗散功率(Pd)为800mW,结合SOT-23封装的散热能力,可满足小功率连续工作需求;工作温度范围(-55℃~+150℃)覆盖工业级与消费级设备的环境要求,适应户外或恶劣工况。
WNM3008-3/TR采用SOT-23封装,尺寸约2.9mm×1.6mm×1.1mm,属于小型表面贴装封装,适合高密度PCB布局(如便携设备紧凑主板)。3脚引脚(漏极D、源极S、栅极G)焊接工艺成熟,兼容回流焊、波峰焊等常规工艺。
散热方面,通过PCB源极焊盘向主板散热,800mW的Pd值在该封装下表现可靠;若需更高功率应用,可通过增加源极焊盘面积或辅助散热片进一步提升散热能力。
WNM3008-3/TR凭借“低压、小体积、高效率”的核心优势,成为便携电子、电源管理等领域的实用型MOSFET选择,适合对成本与性能平衡要求较高的应用场景。

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.
