SMF5.0CA-TP 产品概述

一、产品简介

SMF5.0CA-TP 是 MCC(美微科)出品的一款高可靠性双向 TVS 二极管,专为 5V 级电源与信号线的瞬态过压保护设计。该器件在标准测试条件下具有 200W 峰值脉冲功率能力,并满足 IEC 61000-4-2 静电放电防护要求,能够在恶劣电磁环境中保护敏感电子元件,适用于通信、工业控制、车载电子和消费类设备等场景。

二、主要电气参数

  • 钳位电压(Vc):9.2 V(典型)
  • 工作电压(Vrmw):5 V(额定反向截止电压,适用于 5V 系统)
  • 击穿电压(Vbr):6.4 V(典型)
  • 峰值脉冲功率(Ppp):200 W(标准脉冲条件下)
  • 峰值脉冲电流(Ipp):21.7 A
  • 反向电流(Ir):400 μA(在 Vrwm 条件下)
  • 极性:双向(Bidirectional)
  • 工作温度范围:-65 ℃ 至 +175 ℃
  • 防护等级/标准:IEC 61000-4-2(ESD)
  • 封装:SOD-123FL(低轮廓、小体积)

三、核心特点与优势

  • 双向结构:可在正负瞬态电压下工作,适合交流或双向传输线的瞬态抑制。
  • 高能量吸收能力:200W 峰值功率与 21.7A 峰值脉冲电流,能有效吸收短时大电流冲击。
  • 低钳位电压:9.2V 钳位能在保护目标器件的同时减少剩余冲击能量。
  • 宽温度适应性:-65 ℃ 至 +175 ℃ 工作温度区间,满足汽车级及工业级环境要求。
  • 封装优势:SOD-123FL 提供低剖面和良好焊接性,便于表面贴装和自动化生产。

四、典型应用场景

  • 5V 电源轨防护(MCU、电源模块)
  • USB、UART、I2C 等数据线的 ESD 与浪涌保护
  • 工业控制设备的接口保护(传感器、继电器驱动端)
  • 汽车电子辅助保护(车内通信总线、控制单元接口)
  • 消费类电子产品的输入端口与外设连接保护

五、使用建议与注意事项

  • 安装位置:尽量靠近被保护端口或连接器放置,缩短保护元件到受保护节点的走线长度,以降低感抗带来的钳位电压上升。
  • 热设计:对于经常会承受脉冲能量的场合,建议在 PCB 布局中考虑充足的铜箔面积或散热通孔以帮助散热。
  • 极性选择:若保护对象为固定极性的直流电源轨,可评估是否采用单向 TVS;本产品为双向,适合需双向防护的场合或差分信号线。
  • 可靠性验证:在最终产品中应结合实际浪涌/ESD 环境进行系统级验证,确认钳位水平与残压满足被保护器件安全裕度。
  • 焊接与储存:遵循器件供应商及行业焊接规范(如 JEDEC/IP C 标准)进行回流焊工艺控制,避免长时间高温或潮湿环境存放。

六、封装与订购信息

  • 型号:SMF5.0CA-TP
  • 品牌:MCC(美微科)
  • 封装形式:SOD-123FL,适用于自动贴片装配
  • 建议在采购与设计阶段索取完整数据手册(Datasheet)以获取详细的电气性能曲线、封装尺寸和回流焊曲线等信息。

SMF5.0CA-TP 以其低钳位、高能量吸收能力和宽温范围,适用于对 5V 级电源与接口要求高可靠保护的应用。选型时请结合系统级电压、允许残压及散热条件,参照厂商详细数据手册完成最终设计验证。

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
