IRL1404ZSTRLPBF 产品概述

一、概述

IRL1404ZSTRLPBF 为英飞凌(Infineon)系列的 N 沟道功率 MOSFET,单只封装为 D2PAK(TO-263)。器件面向中低压大电流开关应用,结合低导通电阻与较高的耗散功率,适用于车载 12V 平台、同步整流、DC-DC 变换器与功率开关等场合。

二、主要参数

  • 型号:IRL1404ZSTRLPBF
  • 极性:N 沟道
  • 漏—源耐压 Vdss:40 V
  • 连续漏极电流 Id:200 A(实际允许电流受散热条件限制)
  • 导通电阻 RDS(on):3.1 mΩ @ Vgs=10 V, Id=75 A
  • 耗散功率 Pd:230 W(典型条件下)
  • 栅—源阈值电压 Vgs(th):2.7 V
  • 总栅极电荷 Qg:75 nC
  • 输入电容 Ciss:5.08 nF
  • 反向传输电容 Crss:570 pF
  • 输出电容 Coss:970 pF
  • 工作结温 Tj:-55 ℃ ~ +175 ℃
  • 封装:D2PAK(TO-263)

三、关键特性与性能说明

  • 低导通电阻带来较小的导通损耗,适合高电流连续导通场合;RDS(on) 标注条件为 Vgs=10V、Id=75A,实际在高温或较低 Vgs 下会上升。
  • 较大的 Qg(75 nC)与 Crss(570 pF)意味着在开关过程中需要较大栅极驱动电流以获得较短的开关时间,否则开关损耗将显著增加。
  • 较宽的工作结温范围(最高 175 ℃)有利于在严苛环境下的可靠性,但需配合良好散热设计以保证长期稳定。

四、热管理与封装注意事项

  • D2PAK 为平面大引脚封装,适合焊接至具散热铜皮的 PCB。实际连续电流能力高度依赖于 PCB 散热(底铜面积、过孔和散热层)。
  • 推荐在 PCB 下方增加散热铜箔并使用热过孔将热量传导到内/底层;必要时并联散热片或将器件焊接到散热板。
  • 参考 Pd=230W 的额定功耗时,需确认测量条件(如 Tc=25 ℃)并按器件额定热阻计算允许电流。

五、驱动与开关建议

  • 为达到标称 RDS(on),建议使用 10–12 V 的栅极驱动电压。若由 5V 逻辑直接驱动,注意导通损耗增加且热升高明显。
  • 由于 Qg 较大,驱动器需有足够峰值电流能力(例如多安培级)以快速充放电栅极,降低开关损耗与过渡热应力。
  • 布线时尽量缩短栅极与源极回路的寄生电感,使用合理的门阻以控制 dv/dt 和振铃。

六、典型应用

  • 同步整流和高效率 DC-DC 转换器
  • 车载 12V/24V 电源开关与保护电路
  • 电机驱动大功率开关器件并联场景(需注意均流)
  • 高电流负载开关与逆变器二级功率侧

七、封装与采购提示

  • 封装:D2PAK(便于表面贴装与 PCB 散热布局)
  • 在并联使用多颗器件时,注意栅极驱动一致性与热分布,推荐采用电流均衡与并联设计规范。
  • 采购与样片测试时,应参照完整数据手册验证热阻、脉冲极限、SOA(安全工作区)与封装焊接工艺要求。

概述基于所给基础参数整理,具体电路设计请以原厂数据手册和实测为准,并在高功率场合做好热仿真与实验验证。

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
