SK2301AAT 产品概述

一、概述

SK2301AAT 是时科(SHIKUES)推出的一款小封装 P 沟道功率 MOSFET,封装为 SOT-523,面向便携与空间受限的低电压高侧开关与电源管理场景。器件额定漏源电压为 20V,适用于锂电池、电池背板及小功率开关电源等场合,具备较低的导通电阻与适中的开关特性,便于直接与逻辑或 MCU 配合实现高侧控制。

二、主要参数(典型)

  • 漏源耐压 Vdss:20 V
  • 连续漏极电流 Id:2.3 A(器件规格)
  • 导通电阻 RDS(on):130 mΩ @ Vgs = 4.5 V, Id = 2.3 A
  • 耗散功率 Pd:700 mW(器件热耗散上限,实际应用需考虑 PCB 散热)
  • 栅极电荷 Qg:3.9 nC @ Vgs = 4.5 V
  • 输入电容 Ciss:290 pF @ 10 V
  • 反向传输电容 Crss:29 pF @ 10 V
  • 工作温度范围:-55 ℃ ~ +150 ℃
  • 封装:SOT-523(超小型)

注:资料中对功耗有不同标注(部分资料显示 350 mW),设计时请以最终正式数据表为准。

三、性能亮点

  • 小封装、体积极小,适配紧凑型电路板与便携设备。
  • 低 RDS(on)(130 mΩ)在 4.5V 驱动下可实现较低导通损耗。
  • 中等栅极电荷(3.9 nC),在开关频率不高的应用中开关损耗可控。
  • 宽工作温度范围,适应工业级环境。

四、典型应用

  • 锂电池保护与负载开关(高侧负载控制)
  • 耳机、可穿戴与移动设备电源切换
  • 电源管理 IC 的外部开关元件
  • 反向连接保护与电源隔离
  • 小功率 DC-DC 变换器的同步或旁路开关(低到中频)

五、设计与使用建议

  • 高侧驱动:作为 P 沟道器件,门极需较源极更高或更低电压以实现关闭/开启,常见做法是将源接正电源,门通过 MCU/电阻拉至接地完成导通。
  • 散热管理:SOT-523 封装热阻较大,器件 Pd 受 PCB 铜面积影响显著。若持续电流接近额定值,应增大铜箔面积并使用散热通孔。
  • 开关速度控制:为抑制振铃与过冲,建议在栅极串联 10~100 Ω 的阻尼电阻;驱动电容(Ciss)与 Qg 指标用于评估驱动器能力与切换损耗。
  • 保护电路:驱动感性负载时,建议并联合适的二极管或 RC 吸收网络,并在必要位置添加 TVS 防浪涌。

六、典型计算示例

在 RDS(on)=0.13 Ω、Id=2.3 A 条件下,导通损耗 P = I^2·R ≈ 0.69 W,接近器件标称耗散能力,说明在满载时需靠 PCB 散热降低结温,否则需降低持续电流或改用更大功率器件。

七、存储与装配注意

  • MOSFET 对静电敏感,生产和装配过程中需采取 ESD 保护(佩戴手环、使用接地工作台)。
  • 小封装对回流焊工艺与湿敏等级(MSL)敏感,请按厂家回流温度曲线与湿度保存要求操作。

八、订购信息

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
