5N10 SOT-89(KUU)产品概述

一、概述

5N10 是 KUU 出品的一款单颗 N 沟道增强型功率 MOSFET,采用 SOT-89 小型封装,额定漏源耐压 100V,适用于中低功率开关与线性场合。器件在体积受限的表贴设计中提供较好的电压支撑能力,适合便携电源、开关电源外围开关以及一般负载控制应用。

二、主要特性

  • 类型:N 沟道功率 MOSFET(单颗)
  • 漏源电压 Vdss:100V
  • 连续漏极电流 Id:5A(请按封装与散热条件适当降额)
  • 导通电阻 RDS(on):100 mΩ @ Vgs = 10V
  • 阈值电压 Vgs(th):约 2.5V
  • 栅极电荷 Qg:4 nC @ 10V(栅驱动能量需求低)
  • 输入/输出/反向电容:Ciss = 210 pF,Coss = 30 pF,Crss = 2 pF
  • 耗散功率 Pd:2W(SOT-89 封装)
  • 工作温度范围:-55 ℃ ~ +150 ℃
  • 封装:SOT-89(表面贴装)

三、电气参数要点与影响

  • RDS(on)=100 mΩ 在 Vgs=10V 条件下为典型值,工作电流接近 5A 时导通损耗 P≈I^2·R,会显著升温,建议在高电流工况下改善散热或降额使用。
  • 低 Qg(4 nC)和中等 Ciss(210 pF)使其在开关频率不太高的 DC-DC 或 PWM 应用中驱动损耗小,适合使用简单驱动电路或单级驱动器。
  • Crss(2 pF)较小,有利于减少米勒效应导致的开关延时与振荡概率。
  • Pd 为 2W,SOT-89 封装的散热能力受 PCB 铜箔面积影响大,实际允许持续电流需按 PCB 散热设计计算。

四、热管理与封装注意

  • SOT-89 封装体积小但散热通道有限,建议在 PCB 中为器件底片和引脚处铺设大面积散热铜箔,并在必要时增加过孔引至底层散热层。
  • 在高环境温度或连续较大负载条件下,应进行结温(Tj)和外壳温度评估并对额定 Pd 进行降额。
  • 建议在布局时缩短大电流路径,避免热源集中,并在器件附近留出热散逸空间。

五、典型应用与使用建议

  • 低/中功率开关电源开关管、降压(同步或非同步)外围开关
  • 负载开关、电源管理、继电器替代
  • 中小功率电机驱动、LED 驱动(需考虑导通损耗与散热)
  • 使用时推荐:在栅极串联 10–100 Ω 阻尼以抑制振荡;并在感性负载侧配备续流二极管或 RC 吸收以降低开关应力;栅极控制电压不超过厂家规定的最大 Vgs(通常 ±20V,使用前请参照数据手册确认)。

六、包装与选型建议

  • 单颗封装:SOT-89,适合空间受限且需一定功率处理能力的设计。
  • 选型时权衡点:若系统工作电流长期接近 5A 或需要极低导通损耗,可考虑更大封装或 RDS(on) 更低的器件;若关注开关损耗和驱动能量,5N10 的低 Qg 有优势。

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.

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.

Replenishment inquiry Typical RFQ workflow
