IRLL014NTRPBF-VB 产品概述

一、产品简介

IRLL014NTRPBF-VB 是 VBsemi(微碧半导体)推出的一款单通道 N 沟道功率场效应晶体管,采用 Trench 工艺制造,流片采用台积电(TSMC),封装由长电科技(JCET)完成,封装形式为 SOT-223-3。器件面向小功率开关与线性应用,兼顾低导通损耗与适度开关性能,适用于电源管理、传感器模块、LED 驱动及便携式电子产品等场合。

二、主要特色

  • 额定漏源电压:Vdss = 60V,适合中低压电源与开关应用。
  • 连续漏极电流:Id = 4.5A(受封装及PCB散热能力限制)。
  • 低导通电阻:RDS(on) = 76mΩ @ VGS = 10V;85mΩ @ VGS = 4.5V,适合在 10V 驱动下获得更低导通损耗。
  • 中等栅极电荷:Qg = 22nC @ 10V(10nC @ 4.5V),驱动能量要求适中。
  • 电容参数:Ciss = 810pF,Crss = 100pF,Coss = 120pF,有利于评估开关和回灌特性。
  • 宽工作温度:-55°C ~ +150°C,满足工业级温度要求。
  • 包装便于 PCB 安装与散热:SOT-223-3,带导热大引脚(Tab 为漏极)。

三、关键电气参数(要点)

  • VDS(max):60V
  • ID(cont):4.5A(需结合 PCB 铜层与散热考虑实际持续能力)
  • RDS(on):76mΩ@VGS=10V;85mΩ@VGS=4.5V
  • VGS(th):典型范围 1.0 ~ 2.5V(门槛电压依工况略有差异)
  • Pd(功耗耗散):3W(SOT-223 封装典型)
  • Qg(总栅极电荷):22nC@10V;[email protected]
  • 频率相关电容:Ciss=810pF、Crss=100pF、Coss=120pF

四、应用场景

  • 便携式电源开关与负载断电管理(低功耗模式控制)
  • 传感器与接口电源开关(受限封装下的中小电流驱动)
  • LED 驱动与恒流控制(中低电压 LED 阵列)
  • 电源管理模块(降压/升压转换器的低侧开关、同步整流场合)
  • 工业与消费电子中需要 60V 耐压且体积受限的场合

五、设计与使用建议

  • 驱动电压:若要求最低导通损耗,门极驱动建议接近 10V;在 4.5V 驱动时 RDS(on) 会增加(约 85mΩ),适用于逻辑电平驱动但损耗更高。
  • 散热管理:SOT-223 的 Pd≈3W 为理想条件下数值,实际持续电流需参考 PCB 铜层面积和热阻。典型 4.5A 在短时可行,但长时间大电流建议加大铜箔或外部散热。
  • 开关性能:Qg 中等(22nC@10V),在高频开关应用中需配合合适的驱动器以降低开关损耗并避免门极振铃;建议加入门极电阻并在必要时并联阻尼网络或 TVS。
  • 感性负载保护:驱动电感性负载时应采用续流路径或RC/snubber/TVS 抑制瞬态,保护器件与系统。
  • 布局要点:将源与地回流路径短化,漏极大引脚(Tab)保证良好焊接以提升散热;将驱动回路与功率回路分离以减小干扰。

六、封装与引脚说明

  • 封装:SOT-223-3(小型贴片,便于手工焊接与波峰/回流工艺)。
  • 引脚提示:SOT-223 的大金属 Tab 通常为漏极(Drain),建议将 Tab 与大面积铜箔相连以获得更好散热。具体引脚排列请以正式器件封装图纸为准。

总结:IRLL014NTRPBF-VB 在 60V 耐压、4.5A 电流等级下提供了较低的导通电阻和适中的开关特性,适合体积受限的功率开关与管理场合。在设计时应重视驱动电压、散热与感性负载保护,以发挥该器件的最佳性能。若需完整电气特性曲线与封装图纸,建议索取厂方详细 datasheet 以便最终电路仿真与热设计。

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.
