YJL3134KADW 产品概述

YJL3134KADW 是扬杰(YANGJIE)基于 French Power LV MOSFET 工艺开发的双 N 沟道低压功率 MOSFET,封装为 SOT-363(小封装)。器件面向便携与消费类电子中对开关与保护要求较高的低电压应用,兼顾高可靠性与良好工艺一致性。

一、主要特性

  • 器件类型:双 N 沟道 MOSFET(2×N-channel)
  • 漏源耐压:Vdss = 20 V
  • 额定连续漏极电流:Id = 800 mA(标准测试条件)
  • 导通电阻:RDS(on) = 700 mΩ @ Vgs = 1.8 V
  • 阈值电压:Vgs(th) = 1.1 V
  • 总栅极电荷:Qg = 800 pC @ Vgs = 4.5 V
  • 输入/输出/反向传输电容:Ciss = 33 pF,Coss = 20 pF,Crss = 10 pF
  • 功耗耗散:Pd = 290 mW(器件封装限制)
  • 封装:SOT-363,Moisture Sensitivity Level = 1
  • 环保与安全:环氧树脂达到 UL 94 V-0 阻燃等级,符合无卤标准

二、电气性能要点说明

YJL3134KADW 在 20 V 以下的低压域内表现稳定,RDS(on) 在 Vgs=1.8 V 时约 700 mΩ,适合低压小电流的开关或保护电路。Qg 较大(800 pC @4.5 V),表明若用于高频大电流开关,应关注驱动能力与开关损耗。器件电容值较小,适合高速开关场景中对寄生影响可控的设计。

三、热设计与使用建议

SOT-363 为微小封装,Pd = 290 mW 对功率耗散有较强限制。尽管标称 Id 可达 800 mA,但实际连续工作电流应根据系统散热条件降额使用:

  • 在连续高电流场景,优先考虑并联、外部散热或换用更大封装器件;
  • 管脚布局与 PCB 热铜面积对散热影响显著,建议增加散热铜箔和热通孔;
  • 高速切换时由于 Qg 大,会带来较高的开关损耗和峰值电流,需匹配合适的驱动电路或限制开关频率。

四、典型应用

  • 移动终端与消费电子的电源路径控制、负载开关与电池保护
  • 低压信号开关、搬运小电流负载的电路板级开关
  • USB/Type-C 辅助开关、功率路径隔离(低功率场景)
  • 对体积和可靠性有严格要求的小型化模块

五、封装与可靠性

SOT-363 小型封装利于空间受限的应用,器件符合 MSL1(无吸湿限制造作要求),环氧树脂满足 UL 94 V-0 阻燃等级并为无卤配方,便于消费电子和工业产品的可靠性与环保合规设计。

六、选型与工程提示

  • 若应用要求连续大电流或低导通损耗,应选择更低 RDS(on) 或大封装器件;
  • 高速开关应用需评估 Qg 对驱动器的要求,必要时采用专用驱动芯片或限制开关频率;
  • PCB 热设计(铜面积、过孔)对提升可用电流能力效果显著;
  • 在规格边界工作前,建议基于实际 PCB 和温度条件做功耗与热仿真验证。

YJL3134KADW 在小封装下提供便捷的双通道 MOSFET 解决方案,适合空间受限、低压低功率的开关和保护场景。选择和设计时应综合考虑封装散热与开关驱动要求,以确保长期稳定运行。

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
