YJL3400B 产品概述

一、产品简介

YJL3400B 是一款采用沟槽功率中压 MOSFET 技术的 N 沟道场效应管,面向中小功率高速开关场合。器件在 30V 漏源耐压下提供低电阻、快速切换特性,适合电源管理、负载开关和高频开关应用。其小型 SOT-23(TO-236)封装兼顾占板面积与成本,是便携设备与工业控制的实用选择。

二、主要参数

  • 类型:N 沟道 MOSFET(沟槽工艺)
  • 漏源电压 Vdss:30 V
  • 连续漏极电流 Id:5.6 A
  • 导通电阻 RDS(on):45 mΩ @ Vgs=2.5 V
  • 阈值电压 Vgs(th):1.5 V
  • 总栅极电荷 Qg:16 nC @ 10 V
  • 输入电容 Ciss:610 pF; 输出电容 Coss:60 pF; 反向传输电容 Crss:50 pF
  • 耗散功率 Pd:1 W(封装热容量相关,需注意散热)
  • 工作温度范围:-55 ℃ ~ +150 ℃
  • 湿度敏感度:MSL 1;环氧树脂符合 UL 94 V-0, 无卤
  • 封装:SOT-23(TO-236);品牌:YANGJIE(扬杰)

三、性能特点

  • 逻辑电平驱动:在 2.5V 驱动下已能达到 45 mΩ 的低导通电阻,适合与低压 MCU 或 PMIC 直接接口。
  • 高速开关:较低的 Crss 与适中 Qg 实现快速上升/下降时间,利于降低开关损耗并提高效率。
  • 宽温度范围与可靠封装:可在严苛环境下工作,封装阻燃且无卤,满足安全与环保要求。
  • 小封装大电流:SOT-23 封装在合理散热条件下可承载较高瞬时电流,适合节省 PCB 面积的设计。

四、典型应用

  • DC–DC 升/降压转换器主/同步开关
  • 移动设备与电池管理系统(负载开关、倒灌保护)
  • LED 驱动与背光控制
  • 小功率电机驱动、继电器替代
  • 通信与工业控制中的功率切换电路

五、封装与可靠性

SOT-23(TO-236)小封装便于自动贴装与大规模生产。器件为湿度敏感度等级 1(MSL1),出厂后无需回流前烘烤处理。环氧封装满足 UL 94 V-0 阻燃标准并且无卤,利于满足行业安全与环保规范。具体引脚排列与封装图请参考器件数据手册。

六、设计与使用建议

  • 散热:器件 Pd 标称 1 W,建议在 PCB 设计中使用适量铜箔散热、增加散热过孔以降低结温。
  • 栅极驱动:Q g=16 nC(10 V)表明在高频下需考虑驱动能力,建议根据开关频率选择合适的栅极驱动器或串联门阻(常见 10–47 Ω)以抑制振荡。
  • 保护措施:对于感性负载,应并联 TVS 或 RC 吸收网络以限制 Vds 峰值并保护器件。
  • 布局:缩短源极与驱动器之间的回流路径,合理安置地平面,减小寄生电感与功率损耗。
  • 驱动电压:尽管在 2.5 V 即能有效导通,但若追求更低 RDS(on) 可在允许条件下提高 Vgs。

YJL3400B 以其逻辑电平驱动能力、快速开关特性和小巧封装,适合对效率与体积有严格要求的中小功率场合。对于具体电路设计与热设计,建议结合参考电路与实际板级测试优化。

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
