SMF5.0CA 产品概述
一、产品简介
SMF5.0CA 为双向瞬态抑制二极管（TVS），由 DOWO（东沃）提供，采用 SOD-123 小封装，专为保护 5V 及周边电路免受雷击、浪涌与静电瞬态过压而设计。器件响应快速、体积小、适合表面贴装，适用于通信、消费电子、汽车电子与工业控制等领域的过压保护。
二、主要电气参数
- 极性：双向
- 反向截止电压（VRWM）：5 V
- 钳位电压（VC）：9.2 V（在指定脉冲条件下）
- 峰值脉冲电流（Ipp）：21.74 A
- 峰值脉冲功率（Ppp）：200 W（8/20 μs 波形）
- 击穿电压（Vbr）：6.4 V
- 反向漏电流（IR）：400 μA（常温典型值）
- 工作温度范围：-55 ℃ ~ +150 ℃
- 封装：SOD-123（表面贴装）
三、特性与优势
- 良好的双向保护能力，适合正负瞬态脉冲抑制。
- 在 8/20 μs 浪涌条件下提供 200 W 峰值吸收能力，钳位电压低，有效降低被保护节点电压应力。
- 小型 SOD-123 封装，便于高密度 PCB 布局与自动贴装生产。
- 宽温工作范围，适应苛刻环境与高温工况。
四、典型应用场景
- USB、串口、以太网等数据接口的浪涌与静电保护；
- 车载电子中微弱信号或总线的瞬态防护（需评估车规级要求）；
- 工业控制设备、传感器接口、电源输入端的过压吸收；
- 消费电子产品的 I/O 端口保护与系统级防雷。
五、封装与可靠性建议
SOD-123 封装利于贴片生产与热管理，但在高能量脉冲下要确保足够的线路板铜箔面积以提升散热性能。建议在被保护端靠近受保护器件处短距离布置 TVS，并预留良好焊盘及散热铜箔。为获得长期可靠性，推荐遵循回流焊曲线并在实际应用中进行热循环和浪涌测试验证。
六、选型与使用注意
- 本型号反向截止电压 5 V，适合保护 5 V 及相近电平系统；请确认系统工作电压与 VRWM 匹配并留有余量。
- 钳位电压 9.2 V 为典型值，实际钳位依浪涌波形与线路阻抗略有差异；设计时以最大允许电压为准。
- 对于频繁或大能量冲击场合，需评估器件的累积热应力与是否需并联/升级更高能量器件。
- 详细绝对最大额定值、典型曲线与封装尺寸请参阅产品数据手册并与供应商确认。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
