SI2347DS-T1-GE3-VB P沟道MOS场效应管产品概述

SI2347DS-T1-GE3-VB是VBsemi(微碧半导体)推出的一款低压P沟道功率MOS场效应管,采用SOT-23小型表面贴装封装,专为低电压、高密度应用场景设计,兼具低导通损耗、快速开关特性与宽温适应性,是便携式设备、低压电源系统的理想器件。

一、产品基本信息

该器件为单管P沟道MOSFET,核心型号为SI2347DS-T1-GE3-VB,由微碧半导体(VBsemi)生产,封装形式为3脚SOT-23(小型表面贴装封装),适合对体积敏感的电路设计,单管封装可直接用于原型开发或批量生产。

二、核心电气参数特性

SI2347DS-T1-GE3-VB的电气参数针对低压应用优化,关键参数及实际意义如下:

2.1 电压与电流参数

  • 漏源击穿电压Vdss:30V(最大额定值)—— 关态下漏极与源极间可承受的最大电压,满足5V、12V等常见低压电源系统的耐压需求;
  • 连续漏极电流Id:5.6A(25℃时)—— 常温下允许的最大连续导通电流,可支撑中等功率负载(如小型电机、电池放电回路);
  • 阈值电压Vgs(th):500mV(典型值)—— 栅源电压达到此值时器件开始导通,低阈值特性适合3.3V单片机等低电压控制电路直接驱动。

2.2 导通与功率特性

  • 导通电阻RDS(on):46mΩ@Vgs=10V—— 导通状态下漏源间的等效电阻,低阻值可显著降低导通损耗(P=I²R),减少电路发热,提升效率;
  • 最大耗散功率Pd:1.6W(25℃时)—— 封装可承受的最大连续功率损耗,结合SOT-23封装的散热能力,满足小功率应用的热管理需求。

2.3 电容与开关特性

  • 输入电容Ciss:1.295nF@Vgs=15V—— 栅极与源极、漏极间的并联电容,影响开关速度,低电容值有助于提升电路响应时间;
  • 反向传输电容Crss:130pF@Vgs=15V—— 漏极与栅极间的电容,是米勒效应的主要来源,该值越小,开关过程中的电压过冲越小,电路稳定性越高;
  • 栅极电荷量Qg:24nC@Vgs=10V—— 驱动器件导通所需的总栅极电荷,低Qg可降低开关损耗,进一步提升电路效率。

2.4 温度特性

  • 工作结温范围:-55℃~+150℃—— 宽温范围覆盖工业级环境(如车载周边、户外设备),满足极端温度下的可靠性要求,无需额外散热设计即可稳定工作。

三、封装与物理特性

SI2347DS-T1-GE3-VB采用SOT-23封装,具有以下优势:

  • 体积小巧:引脚间距紧凑,适合高密度PCB布局(如智能手机、智能手表等便携设备);
  • 表面贴装:可通过回流焊工艺批量生产,焊接可靠性高,降低生产难度;
  • 3脚设计:引脚定义清晰(通常为源极S、栅极G、漏极D),电路设计简单易实现,无需复杂外围电路。

四、典型应用场景

结合参数特性,该器件适用于以下场景:

  1. 便携式电子设备:手机、平板、智能穿戴的电源开关、电池过充/过放保护电路;
  2. 低压电源系统:5V/12V DC-DC转换器的同步整流、负载开关,提升电源转换效率;
  3. 小型电机驱动:玩具电机、小型风扇、微型泵的驱动电路,控制精度高;
  4. LED背光控制:笔记本电脑、显示器的背光亮度调节开关,实现低功耗调光;
  5. 工业/车载周边:传感器模块的电源控制、低功率负载驱动(宽温特性适配车载-40℃~+85℃环境)。

五、品牌与可靠性说明

VBsemi(微碧半导体)是国内专注功率器件研发的厂商,其产品符合RoHS环保标准,且通过了多项可靠性测试(如温度循环、湿度老化、ESD测试等)。SI2347DS-T1-GE3-VB的参数一致性好,批量应用时性能稳定,可替代同类进口器件(如AO3401等),性价比优势明显。

总结:SI2347DS-T1-GE3-VB是一款性能均衡的低压P沟道MOSFET,兼顾低损耗、快开关、小体积与宽温特性,可满足便携式设备、低压电源等场景的多样化需求,是电路设计中的高性价比选择。

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.
