SL2301 产品概述

SL2301 是 Slkor(萨科微)推出的一款小封装 P 沟道场效应管(P‑MOSFET),采用 SOT‑23 封装,适用于低压、高侧开关和电源路径管理场景。其主要电气参数为:耐压 Vdss = 20 V,连续漏极电流 Id = 2.8 A,导通电阻 RDS(on) = 112 mΩ(VGS = |4.5 V|),耗散功率 Pd = 400 mW,阈值电压 |Vgs(th)| ≈ 1 V(测试电流 250 μA),总栅极电荷 Qg = 10 nC(4.5 V),输入电容 Ciss = 405 pF,反向传输电容 Crss = 55 pF,输出电容 Coss = 75 pF,工作温度范围 −55 ℃ ~ +150 ℃。

一、主要特点

  • P 沟道器件,便于做高侧开关,简化驱动电路。
  • 20 V 耐压适合大多数单节锂电池与低压供电系统。
  • 112 mΩ 的导通电阻在小功率应用中能提供较低的导通损耗。
  • 栅极电荷 10 nC 与 Ciss 405 pF 表明驱动电流要求中等,适合 MCU 或简单驱动器配合使用。
  • SOT‑23 封装体积小,适合空间受限的便携设备和消费类电子。

二、典型应用

  • 电池供电设备的高侧开关与断电控制(负载开关)。
  • 电源路径管理与反向电流保护。
  • 便携设备、移动终端、摄像头和传感器等小功率模块的开关控制。
  • 电平移位、信号隔离与低速功率切换场景。

三、使用建议与工程注意事项

  • 热性能:SOT‑23 熔散功率 Pd = 400 mW,器件在高电流下产生的 I²R 损耗可能远超器件耗散能力。示例:若 Id = 2.8 A,理论功率损耗 I²R ≈ 0.88 W,显著高于 Pd,因此实际连续工作电流需受限于 PCB 散热与环境温度,建议通过增大铜箔面积、加装散热层或在设计中限制平均电流。
  • 驱动:P 沟道高侧开关时,栅源电压需向负方向驱动(相对于源极),通常用 VIN 作为参考,微控制器驱动时注意不要超过器件最大 Vgs。QG = 10 nC 表明驱动瞬态电流需求中等,应在快速切换场合使用合适的驱动电阻以控制开关速度与 EMI。
  • 开关损耗与寄生电容:Crss 和 Coss 会影响开关过渡、产生振铃和功耗,设计时可在栅极并联合适的阻尼电阻与 RC 滤波以稳定开关行为。
  • 安全裕量:检查最大额定值、热阻和实际 PCB 温升,避免长期在极限条件下工作;如需稳定大电流输出,建议选用更低 RDS(on) 或更大封装的 MOSFET。

四、封装与采购信息

  • 封装:SOT‑23‑3,适合自动贴片生产,焊盘占位小。
  • 品牌:Slkor(萨科微)。
  • 推荐在物料清单中注明完整型号及封装,配合 PCB 布局时参考厂商尺寸与焊盘建议,确保焊接可靠性与热扩散效率。

总结:SL2301 在 20 V、SOT‑23 体积下提供了较好的高侧开关功能,适合低功耗便携应用及电源管理场景。设计时需重视热量管理与驱动条件,合理匹配 PCB 散热与工作电流,以发挥器件最佳性能。

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
