SMF6.0A 产品概述

一、产品简介

SMF6.0A 是一款针对低压电源与数据线的瞬态电压抑制(TVS)二极管,由 JSMSEMI(杰盛微)提供,采用 SOD-123W 表面贴装封装。器件专为抑制瞬态过压(如雷击、感性负载开关、电磁干扰)设计,能在瞬时高能量冲击下保护敏感电子元件和电路板,适用于 5V/6V 等低压系统防护。

二、主要参数

  • 反向截止电压 Vrwm:6.0 V
  • 击穿电压 Vbr(典型):6.7 V
  • 钳位电压 Vc(Ipp):10.3 V
  • 峰值脉冲电流 Ipp:19.4 A
  • 峰值脉冲功率 Ppp(典型,10/1000 μs 波形):200 W
  • 反向电流 Ir:≤100 μA(部分资料标注为 400 μA,建议以最终出厂规格书为准)
  • 工作温度范围:-55 ℃ ~ +150 ℃
  • 封装:SOD-123W(小型表贴)
  • 类型:单向 TVS

三、关键特性

  • 强抗冲击能力:在标准脉冲测试条件下可承受高达 200 W 的瞬态功率,Ipp 可达 19.4 A,能有效吸收瞬态能量,快速钳位过电压。
  • 低反向泄漏:工作电压附近反向电流低,便于在待机或正常运行时保持系统稳定性(请以出厂数据为准)。
  • 紧凑封装:SOD-123W 提供小尺寸、易贴装的表面封装,便于自动化装配和空间受限电路板设计。
  • 宽工作温度:-55 ~ +150 ℃,适应工业级与汽车级周边环境条件(需参照完整可靠性规格)。

四、典型应用

  • 5V/6V 电源轨浪涌保护(例如单板电源、稳压模块输入侧)
  • USB、电源接口、DC 插口的输入防护
  • 通信接口与数据线(UART、I2C、SPI 等)以及传感器接口防静电/浪涌
  • 工业控制、仪表和消费电子中的瞬态过压保护
  • 辅助用于汽车电子的局部防护(需满足汽车认证和具体应用要求)

五、封装与热管理

SOD-123W 封装尺寸紧凑,易于高速贴装。建议在布局时将 TVS 器件尽量靠近被保护端口或元件,缩短信号/电源回路长度以降低分感和串联阻抗。对于需要频繁承受较大脉冲能量的应用,建议在 PCB 下方或附近加设适当的热沉、铺铜或热过孔(thermal vias),以提升散热能力并保护器件寿命。

六、选型与注意事项

  • 电压匹配:Vrwm 6V 适用于 5V 系统或标称不超过 6V 的电源轨;若系统工作电压较高,应选用额定 Vrwm 更高的型号。
  • 能量能力:200 W(10/1000 μs)为脉冲评估值,实际应用中需核算脉冲波形、重复性与器件余量。
  • 极性与连接:为单向 TVS,使用时注意极性方向;若需双向保护,请选择相应双向型号或并联对称器件。
  • 可靠性:长期承受高能冲击或高温环境会影响寿命,关键场合建议做冗余保护与寿命评估。
  • 数据核对:市场资料中 Ir 有不同标称(100 μA 或 400 μA),请以采购合同或器件出厂规格书为最终准据。

七、订购信息与型号说明

  • 品牌:JSMSEMI(杰盛微)
  • 型号示例:SMF6.0A – SOD-123W,单向 TVS,Vrwm 6V,Ppp 200W。
    在采购前,请确认完整的器件数据手册(Electrical Characteristics、Waveform、包装信息与可靠性测试),如有特殊认证(汽车级 AEC-Q)或抄板/代工要求,请与供应商沟通确认。

Sourcing availability signal

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
