WNM2077-3/TR 产品概述

一、产品简介

WNM2077-3/TR 是 WILLSEMI(韦尔)推出的一款小功率 N 沟道增强型场效应晶体管,采用超小型 SOT-723 封装,适合空间受限且需高开关速度与低驱动能耗的便携及消费电子应用。器件额定耐压 20 V,工作温度范围宽(-55 ℃ 至 +150 ℃),提供可用于 1.8 V 逻辑驱动的低导通电阻和很低的栅极电荷,适合作为低电压开关及负载开关使用。

二、主要特性

  • 类型:N 沟道 MOSFET(增强型)
  • 漏源耐压(Vdss):20 V
  • 导通电阻(RDS(on)):840 mΩ @ VGS = 1.8 V
  • 阈值电压(Vgs(th)):1.0 V @ ID = 250 µA
  • 连续漏极电流(Id):540 mA
  • 最大耗散功率(Pd):360 mW
  • 栅极电荷(Qg):1.07 nC @ VGS = 4.5 V
  • 输入电容(Ciss):30 pF;输出电容(Coss):7 pF;反向传输电容(Crss/Crss):5 pF
  • 工作温度:-55 ℃ ~ +150 ℃
  • 封装:SOT-723(超小型封装)
  • 包装型号:WNM2077-3/TR(TR 表示卷带包装,便于贴片加工)

三、电气参数概览(便于快速对比)

  • 20 V 耐压适合大多数低压系统的开关控制与保护场景;
  • 在 1.8 V 门极驱动条件下 RDS(on) 为 840 mΩ,说明该器件为低电压逻辑兼容器件,适合 1.8 V/2.5 V 系统;
  • 低栅极电荷(1.07 nC @ 4.5 V)与小电容(Ciss 30 pF、Coss 7 pF、Crss 5 pF)有助于降低驱动能耗并提高开关速度,特别适用于需要频繁切换或快速响应的场合;
  • 连续电流能力达 540 mA,配合 SOT-723 封装适合小电流负载开关与信号切换任务;
  • 宽温工作范围保证器件在严苛环境下的可靠性与稳定工作。

四、典型应用场景

  • 电池供电的便携式设备中的负载开关与电源路径切换;
  • 移动终端、可穿戴设备的周边电源管理与外设使能;
  • 低电压逻辑控制的信号开关、电平移位与驱动小电流继电器/LED;
  • 通用低压开关、反向电流保护、短路保护电路中的开关元件;
  • 需要小封装与低漏电、低驱动能耗的消费电子与物联网终端。

五、封装与热管理建议

SOT-723 封装体积极小,适合高密度 PCB 设计,但热阻相对较大,应注意散热与功耗管理:

  • 在 PCB 布局时,为器件的引脚与底部附近安排适量铜箔(散热焊盘)以降低结-环境热阻;
  • 对于连续导通或频繁开关的应用,评估实际损耗(I^2·RDS(on) 与开关损耗)并保证 Pd(360 mW)不被超额使用;
  • 如长时间接近额定耗散功率运行,需在实测环境温度条件下验证结温并根据需要采取散热或降额措施。

六、使用建议与注意事项

  • 门级驱动:器件在 1.8 V 下已标注导通电阻,若需进一步降低 RDS(on) 可考虑 2.5 V 或 4.5 V 驱动,但应参考器件在其他 VGS 下的具体特性曲线(样片或数据手册);
  • 开关性能:低 Qg 与小寄生电容利于高频应用与低驱动功耗,但在快速切换时仍应关注电压尖峰与振铃,必要时加栅极电阻或阻尼网络;
  • ESD 与稳压:SOT-723 的引脚间距小,生产/贴装过程中注意静电防护;同时器件未内置大功率钳位,外加 TVS 或限压方案可提升系统可靠性;
  • 温度降额:在高温环境或长期工作场景,按厂家数据手册的温度-功耗降额曲线进行设计,避免长期过热影响寿命。

七、订购信息与可靠性

  • 订购型号:WNM2077-3/TR(TR 通常表示卷带包装,适配自动贴片生产线);
  • 品牌:WILLSEMI(韦尔)/ 韦尔半导体;
  • 可靠性:器件额定工作温度覆盖 -55 ℃ 至 +150 ℃,适用于工业级和消费级宽温环境。建议在设计初期获取完整的数据手册与可靠性报告(如 HBM/ CDM ESD 等级、温度循环与寿命测试)以满足特定应用的认证要求。

总结:WNM2077-3/TR 是一款面向低压、低功耗、空间受限场合的 N 沟道 MOSFET,具有逻辑电平兼容的导通特性、低栅极电荷与小寄生电容,适合便携设备与电源管理场景。设计时重点关注封装带来的热管理限制与开关瞬态抑制,以确保长期可靠运行。若需完整电气特性曲线或样片评估,建议联系厂商提供的数据手册与工程支持。

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
