SMF5.0A（5.0V） TVS 二极管 产品概述
一、产品简介
SMF5.0A 是晶导微电子推出的一款单向瞬态电压抑制（TVS）二极管，封装为 SOD-123（SOD-123FL）。器件针对瞬态脉冲浪涌和雷击/感性负载释放产生的过压，提供快速钳位保护，典型钳位电压为 9.2V，适用于 5V 等电源和信号线的浪涌防护。
二、主要规格
- 类型：TVS（瞬态抑制二极管），单向
- 反向截止电压 Vrwm：5V
- 击穿电压（Vbr）：7V（典型）
- 钳位电压 Vc（Ipp 条件下）：9.2V
- 峰值脉冲功率 Ppp：200W（10/1000 μs）
- 峰值脉冲电流 Ipp：21.7A（10/1000 μs）
- 反向电流 Ir：450 μA（常温）
- 工作温度范围：-55℃ ~ +150℃
- 封装：SOD-123（低剖面 SOD-123FL）
三、器件特点与优势
- 高能量吸收：在 10/1000 μs 波形下具有 200W 的峰值吸收能力，适合工业级雷击及浪涌保护。
- 低钳位电压：9.2V 钳位能有效保护 5V 系统免受过压损害，同时在抑制瞬态时对下游器件冲击较小。
- 宽工作温度：-55℃ 至 +150℃ 的耐温能力满足工业及汽车环境要求。
- 小型封装：SOD-123FL 占板面积小，适合空间受限的 PCB 布局及自动贴装工艺。
- 单向结构：针对直流和单向电源/信号线路提供更可靠的反向阻断特性。
四、典型应用场景
- 5V 电源总线、USB 接口保护
- 通讯设备、路由器、交换机等网络端口浪涌抑制
- 工业控制、测量仪表的输入/输出保护
- 汽车电子非关键线路的瞬态抑制（需评估 AEC 要求）
- 消费电子中对浪涌和突发干扰敏感的电源或信号节点
五、设计与选型建议
- 在接近保护点布置 TVS，尽量缩短与被保护线之间的走线长度，以降低感性耦合与串联阻抗。
- 对于持续工作电压接近 Vrwm 的场合，注意 Ir（450 μA）可能带来的功耗与热升温；若为敏感模拟电路，应选择更低漏电的型号。
- 若系统可能遭受重复高能冲击，应评估器件的多次冲击寿命和散热条件，必要时并联或选用更高功率等级 TVS。
- SOD-123FL 封装适合自动化贴装，焊接工艺需控制回流温度以保证可靠性。
六、可靠性与合规
器件在宽温范围内保持稳定的钳位和击穿特性，符合通用工业级浪涌保护要求。对特定行业（如汽车）应核实是否满足对应的质量认证或按照系统级标准进行验证。
如需样品、客户化参数（如更低漏电、双向版本或不同 Vrwm 值）或参考电路布局建议，欢迎提供应用场景以便进一步技术支持。

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.
