SI2301ADS-T1-GE3-VB P沟道MOS场效应管产品概述

SI2301ADS-T1-GE3-VB是VBsemi(微碧半导体)推出的低压P沟道增强型MOSFET,采用SOT-23(TO-236)小型表面贴装封装,专为低电压、小电流场景的功率控制设计,具备低导通电阻、低阈值电压等核心优势,广泛适用于便携式电子设备、电池管理等领域。

一、产品基本信息

  • 器件类型:P沟道增强型MOS场效应管
  • 品牌型号:VBsemi微碧半导体,SI2301ADS-T1-GE3-VB
  • 封装形式:SOT-23(TO-236)表面贴装封装(尺寸约2.9×1.6×1.1mm)
  • 核心定位:替代传统三极管的低压小功率开关管,实现低损耗功率控制

二、核心电气参数(需明确测试条件)

1. 极限参数(超出将导致器件损坏)

  • 漏源击穿电压:( V_{DSS} = 20V )(漏极-源极间最大反向耐压)
  • 连续漏极电流:( I_D = 3.5A )(25℃环境下的最大持续工作电流)
  • 最大耗散功率:( P_D = 1.6W )(25℃环境下的最大允许功耗)
  • 工作结温范围:( T_J = -55℃ \sim +150℃ )(器件正常工作的结温区间)

2. 导通特性参数

  • 导通电阻:( R_{DS(on)} = 60mΩ )(( V_{GS} = -10V )、( I_D = 3.5A ) 时的漏源导通电阻,低损耗核心)
  • 阈值电压:( V_{GS(th)} = 500mV )(( I_D = 250μA ) 时的栅源开启电压,低阈值兼容低电压逻辑)

3. 开关特性参数

  • 栅极总电荷量:( Q_G = 6.4nC )(( V_{GS} = -2.5V )、( I_D = 3.5A ) 时的栅极总电荷,影响开关速度)
  • 输入电容:( C_{ISS} = 835pF )(( V_{GS} = 0V )、( V_{DS} = 10V ) 时的输入电容)
  • 反向传输电容:( C_{RSS} = 155pF )(( V_{GS} = 0V )、( V_{DS} = 10V ) 时的反向传输电容,影响高频特性)

三、封装与引脚配置

SOT-23封装为超小型表面贴装结构,适配高密度PCB设计,引脚定义如下:

  • 引脚1:源极(S)
  • 引脚2:栅极(G)
  • 引脚3:漏极(D)

⚠️ 注意:P沟道MOSFET需负栅源电压驱动(( V_{GS} < 0V )),避免极性接反损坏器件。

四、典型应用场景

结合参数特性,该器件主要适用于以下场景:

  1. 便携式电子设备:智能手机、蓝牙耳机、智能手环的电源开关/负载控制(工作电压3.7V~5V,符合20V耐压要求)
  2. 电池保护电路:锂电池充放电回路的开关控制(P沟道适合电池正极侧低损耗开关)
  3. 低电压负载开关:3.3V/5V系统中的小电流负载通断(如LED驱动、传感器供电)
  4. 小型电机驱动:低功率直流微电机(玩具电机、小型风扇)的驱动控制
  5. 电平转换电路:1.8V低电压逻辑与5V系统之间的电平转换

五、产品优势与适用说明

  1. 低导通损耗:60mΩ导通电阻(@10V VGS)大幅降低导通功率损耗,适合低功耗设计
  2. 低电压驱动兼容:500mV阈值电压,可直接由3.3V/2.5V逻辑电路驱动,无需额外电平转换
  3. 小型化设计:SOT-23封装节省PCB空间,适配便携式设备轻薄化趋势
  4. 宽温可靠性:-55℃~+150℃结温范围,适应工业级或极端环境应用
  5. 开关速度较快:6.4nC栅极总电荷,支持高频PWM控制等快速开关场景

六、使用注意事项

  1. 极限参数降额:实际应用需对电压、电流、功耗降额30%~50%,避免长期过载
  2. 栅极静电防护:MOSFET栅极绝缘层易受静电损伤,需做好ESD防护(防静电手环、包装)
  3. 热管理设计:1.6W功耗需在PCB漏极引脚处增加铜箔面积,降低热阻
  4. 驱动电路匹配:栅极串联100Ω~1kΩ限流电阻,避免过流损坏

综上,SI2301ADS-T1-GE3-VB平衡了小封装、低损耗与宽温可靠性,是低压小功率场景的高性价比选择。

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.

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
