WNM2016 产品概述
WNM2016 是 KUU 推出的一款小封装、高性价比的 TrenchFET N 沟道功率 MOSFET，专为便携设备与低功耗 DC/DC 电源应用设计。器件以 SOT-23 卷带封装提供，兼顾体积、导通损耗与开关性能，适合作为负载开关、同步整流或低侧开关使用。
一、主要规格
- 类型：N 沟道 MOSFET（TrenchFET）
- 漏源电压 Vdss：20 V
- 连续漏极电流 Id：4.2 A
- 导通电阻 RDS(on)：45 mΩ @ Vgs = 4.5 V
- 阈值电压 Vgs(th)：1.2 V
- 总耗散功率 Pd：1.25 W
- 栅极电荷 Qg：8 nC @ Vgs = 4.5 V
- 输入电容 Ciss：740 pF
- 反向传输电容 Crss：66 pF
- 封装：SOT-23（支持卷带）
二、产品特性
- 超低导通电阻，有效降低导通损耗，提升效率与发热控制。
- 采用 TrenchFET 工艺，具备较好的导电携带能力与低热阻比。
- 中等栅极电荷（Qg = 8 nC），在 4.5 V 栅压下能快速切换，适配常见 MCU/驱动器。
- 小封装设计，便于在空间受限的便携设备中使用并支持自动贴片生产（卷带供货）。
三、典型应用场景
- 便携设备的电源负载开关与电池保护切换
- 小功率 DC/DC 转换器（作为低侧开关或同步整流器）
- 电池管理系统、移动终端、物联网终端及便携式外设
- 通用开关控制与功率路径管理
四、设计注意事项
- 工作模式：由于 Vdss = 20 V，适合低压系统；作为高侧开关时需注意栅电压需高于源极，若直接当高侧开关使用请确认驱动能提供足够 Vgs。
- 驱动与开关速度：Qg = 8 nC、Ciss = 740 pF，驱动器需能提供相应电流以满足开关频率要求。为控制振铃与 EMI，可在栅极串联合适的栅阻（如 5–50 Ω）。
- 热管理：封装 Pd = 1.25 W，在高电流或高占空比场合需注意 PCB 散热设计，增大铜箔面积并在封装下方/附近布局散热铜皮和过孔以降低结温。
- 布线建议：输入与输出电源走线尽量短粗、靠近器件；将退隙电容（旁路电容）靠近 MOSFET 的电源/地端放置以降低寄生感抗。
- 保护与可靠性：对负载开关建议并联 TVS 或在电源线上加入软启动电路以缓解浪涌电流；在电感性负载场合注意反向恢复与钳位需求。
五、封装与采购
- 封装形式：SOT-23，支持卷带（适合贴片自动化生产）
- 品牌：KUU
- 典型单件数量：1 片/型号；批量采购按卷带规格
总结：WNM2016 在 SOT-23 小体积下提供较低的 RDS(on) 与可观的电流承载能力，是便携式设备负载开关与低压 DC/DC 电源设计中兼顾成本与效率的实用选择。设计时重点关注栅驱动、散热与 PCB 布局，可在保证可靠性的同时发挥其高效低耗的特性。若需更详细的电气特性曲线、热阻数据或封装尺寸图，请参考器件规格书。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Sourcing availability signal
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
Examples of how common component sourcing requests are organized.
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.
