SMF5.0CA 产品概述

一、产品简介

SMF5.0CA 是华轩阳电子(HXY MOSFET)出品的一款高性能瞬态电压抑制器(TVS),封装为 SOD-123FL。该器件为双向保护设计,标称反向截止电压(Vrwm)为 5V,击穿电压在 6.4V 至 7V 之间,能在瞬态冲击中提供可靠的钳位保护,典型钳位电压为 9.2V。峰值脉冲功率 Ppp 为 200W,峰值脉冲电流 Ipp 为 21.7A,反向漏电流 Ir 最大 400µA,工作温度范围宽(-65℃ 至 +150℃),适合工业级及汽车级瞬态抑制需求。

二、主要性能特点

  • 双向极性,适用于交流或双向脉冲场合的浪涌吸收与限制。
  • 低工作电压:Vrwm = 5V,适合 5V 电源总线及 USB 等接口保护。
  • 低钳位电压:典型 Vc = 9.2V,有利于降低被保护器件的应力。
  • 高瞬态承受能力:Ppp = 200W,Ipp = 21.7A,可应对常见的瞬态浪涌事件。
  • 宽温度工作范围:-65℃~+150℃,适应恶劣环境与高温场合。
  • 封装小巧:SOD-123FL,有利于节省 PCB 面积并实现自动贴装。

三、典型应用场景

  • 5V 电源轨保护(例如 USB、通信模块供电)。
  • 串行数据接口保护(如 RS-485、CAN 总线,需双向保护时尤为合适)。
  • 工业控制器、传感器前端的瞬态抑制。
  • 汽车电子的稳压与浪涌保护(需满足温度与耐压要求时)。
  • 电源适配器输出端、DC-DC 变换器及继电器驱动线路的浪涌保护。

四、典型电气参数(概要)

  • 极性:双向
  • 反向截止电压 Vrwm:5V
  • 击穿电压:6.4V ~ 7V
  • 钳位电压 Vc(典型):9.2V
  • 峰值脉冲电流 Ipp:21.7A
  • 峰值脉冲功率 Ppp:200W
  • 反向漏电流 Ir:≤400µA
  • 工作温度:-65℃ ~ +150℃
  • 封装:SOD-123FL

(注:以上参数请以厂家最新数据手册为准;钳位电压通常对应特定测试条件下测得,实际电路中与脉冲波形和源阻抗有关。)

五、选型与使用建议

  • 确认工作电压:器件 Vrwm 为 5V,适合稳态电压 ≤5V 的系统。若系统空载或瞬态允许更高电压,需重新评估余量。
  • 钳位要求:比较器件钳位电压 9.2V 与被保护器件的耐压极限,确保在浪涌情况下不会超出被保护器件允许值。
  • 浪涌能力匹配:考虑系统可能出现的最大冲击电流,选择 Ipp 与 Ppp 足够的器件或并联/并用更高等级 TVS。
  • 封装布局:SOD-123FL 建议靠近被保护端口贴装,附近保持清晰的散热路径,减小系列阻抗以提高响应速度。
  • 温度与可靠性:在高温环境下应注意漏电流上升及寿命影响,必要时选择更高温等级或采取降温措施。

六、封装与安装注意事项

  • SOD-123FL 为小型塑封贴片,双端电极设计,便于自动贴装与回流焊工艺。
  • 焊接温度与曲线应遵循供应商推荐的回流规范,避免过度热应力引起性能退化。
  • 对于高能量冲击应用,建议在 PCB 设计中增加热铜箔面积以利散热,并避免紧邻敏感信号线。

七、结论

SMF5.0CA(HXY MOSFET,SOD-123FL)是一款针对 5V 级电源与数据线的高性价比双向 TVS 器件,具备较低钳位电压、良好的瞬态吸收能力及宽温度范围,适用于工业、通信及汽车电子等多种场景。在选型时应综合考虑系统工作电压、允许的钳位电压及预期冲击能量,合理布板与热管理可确保器件长期稳定工作。

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.
