YJG40N03A 产品概述

YJG40N03A 是扬杰(YANGJIE)推出的一款低导通电阻、高电流承载能力的 N 沟道功率 MOSFET,适用于中低压开关电源、同步整流、负载开关与电机驱动等场景。器件采用 PDFN(5×6) 小封装,兼顾了功率密度与良好散热性能,便于 PCB 布局与批量组装。

一、主要参数一览

  • 类型:N 沟道功率 MOSFET
  • 漏源电压 Vdss:30 V
  • 连续漏极电流 Id:40 A
  • 导通电阻 RDS(on):5.5 mΩ @ Vgs = 10 V、Id = 15 A
  • 耗散功率 Pd:18 W(器件额定耗散,实际应用需考虑散热设计)
  • 阈值电压 Vgs(th):约 1 V
  • 总栅电荷量 Qg:23.6 nC @ Vgs = 10 V
  • 输入电容 Ciss:1.015 nF @ 15 V
  • 反向传输电容 Crss:164 pF @ 15 V
  • 工作温度范围:-55 ℃ ~ +150 ℃
  • 封装:PDFN 5×6(便于热流向 PCB 扩散)
  • 单位:1 颗,品牌:YANGJIE(扬杰)

二、性能特点

  • 低导通电阻:在 Vgs = 10 V 时 RDS(on) 仅 5.5 mΩ,适合高电流低压降应用,降低导通损耗与发热。
  • 高电流能力:40 A 连续额定电流,满足高负载瞬态需求。
  • 中等栅电荷:Qg = 23.6 nC,适配常见驱动器,需在高速开关时注意驱动功率与开关损耗。
  • 紧凑封装:PDFN(5×6) 在保证散热面的同时利于小型化设计与自动贴片生产。
  • 宽温度范围:工作温度覆盖工业级需求,可靠性高。

三、典型应用场景

  • 同步整流器与降压(Buck)转换器的开关管
  • DC–DC 电源、PWM 开关电源主开关或同步整流管
  • 汽车电子 12V/24V 系统负载开关与保护电路(注意电磁兼容与浪涌保护)
  • 电机驱动低侧开关与功率管理模块

四、设计与使用建议

  • 栅极驱动:为保证标称 RDS(on),建议驱动电压驱至 10 V。若使用 5 V 驱动,请验证实际 RDS(on) 与导通损耗。
  • 开关频率与驱动选型:Qg = 23.6 nC,较高速开关时驱动器需提供充放电电流以降低开关损耗与过渡热应力。
  • 热管理:器件额定 Pd = 18 W,为保证长期可靠性应通过铜箔散热、热垫与过孔导热等手段降低结温;在高功率密度应用中建议外加散热片或热介质。
  • PCB 布局:大电流回路使用宽铜线、多个过孔分布以降低电阻和提升散热;将热垫与功率铜区连接到器件底面散热区。
  • ESD 与稳压保护:栅极阈值低(≈1 V),在搬运与装配过程中注意静电防护;在实际电路中可考虑栅-源、栅-漏保护电阻与 TVS 二极管来防止浪涌。

五、注意事项与可靠性

  • 请按照器件数据手册中的最大额定值进行设计,避免长期在极限条件下运行以防热应力与迁移效应。
  • 在脉冲大电流或感性负载切换时,注意吸收回路设计(续流二极管或回授网络)以抑制过压。
  • 选型时应结合实际工作电压、开关频率及散热条件做热仿真或样机测试,确保结温与功率损耗在安全范围内。

YJG40N03A 以其低 RDS(on)、高电流能力和紧凑封装,为追求高效率与高功率密度的中低压电源设计提供了可靠选择。欲获取完整电气特性曲线、热阻参数与封装图样,请参考扬杰官方数据手册或联系供应商索取样片测试。

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
