SMF6.5CA 双向 TVS 抑制二极管 — 产品概述

一、产品简介

SMF6.5CA 是 GOODWORK(固得沃克)品牌的一款双向瞬态电压抑制(TVS)器件,采用 GPP 工艺芯片制造,适用于对电源线、信号线及接口端口的瞬态过压保护。产品在设计上兼顾低漏电、高对档率与优良的高温稳定性,适应-55℃ 至 +150℃ 的宽温区工作需求,能够在恶劣环境下维持可靠保护性能。

二、主要电气参数

  • 极性:双向
  • 反向截止电压 Vrwm:6.5 V
  • 击穿电压 VBR:7.22 V(典型)
  • 钳位电压(Ipp 条件):11.2 V
  • 峰值脉冲电流 Ipp:17.9 A
  • 峰值脉冲功率 Ppp:200 W
  • 反向漏电流 Ir:250 μA(常温、Vrwm 条件下)
  • 工作温度范围:-55℃ ~ +150℃
  • 封装:SOD-123FL

以上参数为器件在额定测试条件下的关键指标,实际应用中应参考厂商完整规格书以获得温度、测试脉冲波形等条件下的详细曲线。

三、核心优势

  • GPP 工艺芯片带来低漏电、高对档率及更好的高温稳定性,降低静态功耗且在高温下仍能保持稳定抑制特性。
  • 双向结构适合保护交替极性或双向瞬态(如交流干扰、ESD 反向脉冲)场合,无需外加极性区分。
  • SOD-123FL 封装体积小、散热性能良好,利于表面贴装(SMT)自动化生产。

四、典型应用场景

  • 通信接口与端口保护(如串口、USB、数据线等)
  • 工业控制设备与传感器接口的浪涌防护
  • 电源输入与分配网络的瞬态抑制
  • 消费类电子及嵌入式系统的局部保护单元

五、封装与可靠性

SOD-123FL 封装提供良好的机械强度与可焊性,适合高速贴装线生产。器件设计考虑了高温环境下可靠性,额定工作温度上限 +150℃,但在长期高温或频繁大功率冲击工况下建议进行热管理与可靠性验证。

六、设计与选型建议

  • 选型原则:工作电压(Vrwm)应略高于系统正常工作电压以减少漏电;钳位电压应低于被保护器件允许的最大耐压。SMF6.5CA 的 Vrwm=6.5V 适用于 5V 类及类似电压域的保护。
  • 考虑脉冲能力:Ppp=200W、Ipp=17.9A 表明对短时大能量浪涌有良好承载力,但在更高能量冲击下仍需配合限流元件(如熔断器、阻尼元件)或多级保护方案。
  • 漏电考量:Ir=250 μA 在对静态电流敏感的场合(例如低功耗设备)需要评估是否影响待机功耗。

七、安装与测试注意事项

  • 器件应尽量靠近被保护引脚布置,走线短而粗,减少串联电感与阻抗。
  • 设计合理的焊盘与散热铜箔,有助于脉冲能量散逸与可靠性提升。
  • 在提交量产前进行实际工况下的浪涌/ESD 测试验证(包含不同极性、不同脉冲能量与重复冲击条件),并结合热仿真评估长期稳定性。

如需完整数据手册(IV 曲线、钳位电压随电流变化曲线、热阻、封装尺寸与焊盘建议等),建议索取 GOODWORK 官方规格书以便进行详细的电路保护设计与可靠性验证。

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
