SI2310B-TP 产品概述

一、产品简介

SI2310B-TP 是美微科(MCC)推出的一款小功率 N 沟道场效应管(MOSFET),适用于开关与线性应用。器件采用常见的 TO-236-3 / SC-59 / SOT-23-3 小封装,集成度高,体积小,适合空间受限的消费类和工业电子产品。器件额定参数平衡,既能满足中等电流开关需求,又便于在低功耗系统中实现高效驱动。

二、主要参数

  • 类型:N 沟道 MOSFET,数量:1 只
  • 漏源电压 Vdss:60 V
  • 连续漏极电流 Id:3 A
  • 导通电阻 RDS(on):105 mΩ @ Vgs = 10 V, Id = 3 A
  • 耗散功率 Pd:1.2 W(请注意封装与散热条件)
  • 阈值电压 Vgs(th):0.5 V(典型)
  • 总栅电荷 Qg:6 nC @ Vgs = 4.5 V
  • 输入电容 Ciss:247 pF @ 30 V
  • 反向传输电容 Crss:19.5 pF @ 30 V
  • 工作结温范围 Tj:-55 ℃ ~ +150 ℃
  • 品牌:MCC(美微科)
  • 封装:TO-236-3,SC-59,SOT-23-3

三、关键特性及优势

  • 60 V 的耐压能力适配绝大多数中低压整流、电源和开关场景。
  • 105 mΩ 的导通电阻在 3 A 电流水平下表现均衡,适合中等电流负载的低损耗开关。
  • 较低的总栅电荷(6 nC @ 4.5 V)使其在 4.5 V 驱动电平下开关损耗较小,有利于提高开关效率并减小驱动器负担。
  • 小封装(SOT-23 系列)利于密集 PCB 布局和便携设备的体积优化。
  • 宽工作温度范围和典型的工业级规格,适合多种环境应用。

四、典型应用场景

  • 开关电源(低功率 DC-DC 转换器)与降压/升压模块的开关器件。
  • 负载开关、电机驱动(小型直流电机)及 PWM 调光电路。
  • 电池供电设备的功率管理与保护电路。
  • 通用功率开关、数字电路侧的低侧开关或配合驱动器作高频开关使用(需关注驱动与热设计)。

五、使用注意事项与设计建议

  • 耗散功率 Pd 标称为 1.2 W,实际可用功率强烈依赖 PCB 铜箔面积与散热条件。在高电流或连续工作场景下应采用加大铜箔、过孔强化散热或选择更大封装。
  • RDS(on) 给定值为 Vgs=10 V 条件下的典型值;若在 4.5 V 或更低门压下工作,导通电阻会增加,应在电路仿真或样机测试中确认损耗与发热。
  • Qg 与 Ciss、Crss 指示了器件的开关速度与驱动需求。对于高频开关应用,需评估驱动器的电流能力以确保满足上升/下降时间要求并控制开关损耗与电磁干扰。
  • 针对感性负载(如电机、线圈),建议在器件两端或电源侧加吸收或缓冲电路(例如 TVS、RC 降压网络或斜坡栅驱动)以限制 Vds 的瞬态应力并保护器件。
  • 工作温度升高会导致 RDS(on) 增大,应在高温环境下适当留有裕量并进行热仿真验证。
  • 小封装引脚电阻与散热能力有限,布局时应优化金属层宽度与过孔分布,优先将散热路径与大面积铜箔连接。

总结:SI2310B-TP 在 60 V 电压等级和 3 A 电流等级的应用中表现均衡,适合体积受限且需中等功率开关的场景。设计时关注栅极驱动与散热管理,可在多种消费及工业类应用中获得可靠表现。

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
