SK335N N沟道MOSFET产品概述

一、核心电气参数总览

SK335N为SHIKUES(时科)推出的N沟道增强型MOSFET,参数围绕低电压、小封装、中电流场景优化,核心指标如下:

  • 电压参数:漏源击穿电压(Vdss)=20V(满足5V/12V系统耐压);阈值电压(Vgs(th))=1.3V(典型值,测试条件:Id=250μA),平衡误触发风险与驱动兼容性。
  • 电流参数:25℃下连续漏极电流(Id)=2A;不同驱动电压下的导通电流能力提升——Vgs=2.5V时最大3.1A,Vgs=4.5V时最大3.6A(脉冲电流需参考datasheet占空比限制)。
  • 导通电阻:Vgs=2.5V时RDS(on)=75mΩ,Vgs=4.5V时RDS(on)=80mΩ,低损耗特性显著。

二、封装与品牌背景

  • 品牌:由国内功率器件厂商SHIKUES(时科)研发,该品牌专注小封装MOSFET,以“高性价比+高可靠性”覆盖消费电子、通信等领域。
  • 封装:采用SOT-23超小型表面贴装封装,尺寸2.9×2.5×1.1mm,引脚间距0.95mm,适配高密度PCB设计(如便携式设备);散热依赖PCB铜箔传导,需预留足够铜箔面积。

三、关键性能优势

  1. 低导通电阻适配低电压驱动:2.5V驱动下RDS(on)仅75mΩ,可直接由3.3V MCU驱动,无需额外升压电路,简化系统设计。
  2. 阈值电压平衡可靠性与兼容性:1.3V阈值避免低电压(<1V)误导通,同时无需高驱动电压即可实现低损耗导通,适配绝大多数嵌入式系统。
  3. 小封装实现中电流能力:SOT-23封装下实现连续2A输出,脉冲电流达3.6A,打破传统小封装MOSFET的电流限制。
  4. 低电压耐压避免过度设计:20V Vdss针对低电压系统优化,既满足锂电池(3.7V/7.4V)、5V电源等场景需求,又不增加不必要的成本。

四、典型应用场景

SK335N的参数特性使其在低电压、小体积、中电流场景中表现突出,典型应用包括:

  • 便携式设备电源管理:智能手环、蓝牙耳机、移动电源的输出开关、电池过充/过放保护;
  • 小型负载驱动:LED灯串(<2A)、小型直流电机(玩具/微型设备)、低功耗继电器线圈驱动;
  • 低电压电源系统:5V/12V电源的负载开关、小型充电器通断控制;
  • 通信模块控制:小型路由器、蓝牙模块的电源开关、信号路径切换。

五、应用设计注意事项

为保障可靠性与性能,设计需注意:

  1. 驱动电压范围:建议Vgs控制在2.5V~4.5V,避免超过10V(虽最大Vgs为±20V,但过高驱动加速老化);
  2. 散热设计:连续2A工作时,PCB需预留≥10mm²铜箔(可通过过孔连接上下层提升散热),避免结温超150℃;
  3. ESD防护:SOT-23封装ESD敏感度为HBM 2000V,生产需采用静电防护(接地工作台、离子风扇);
  4. 电流降额:环境温度超25℃时,连续电流需降额(如85℃时Id≈1.5A,100℃时Id≈1A,参考datasheet降额曲线)。

SK335N凭借小封装、低损耗、适配低电压驱动的特性,成为便携式设备、小型电源系统的理想功率开关器件。

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
