SMF22A 产品概述
一、产品简介
SMF22A 是一款单向瞬态电压抑制器（TVS），由 GOODWORK（固得沃克）提供，采用 GPP 工艺芯片制造，具备低漏电、高对档率的特性，适用于对电源和信号线抗浪涌、抗雷击及抗静电干扰的保护需求。器件采用 SOD-123FL 小型封装，适合表贴安装，工作温度范围宽（-55℃~+150℃），在恶劣环境下仍能保持稳定性。
二、主要性能参数
- 极性：单向
- 反向截止电压 Vrwm：22 V
- 击穿电压 VBR：24.4 V
- 钳位电压 Vc：35.5 V
- 峰值脉冲电流 Ipp：5.6 A
- 峰值脉冲功率 Ppp：200 W
- 反向漏电流 Ir：1 μA（常温）
- 通道数：单路
- 工作温度：-55℃ 到 +150℃
- 封装：SOD-123FL
三、特点与优势
- GPP 工艺芯片带来更低的漏电流和更高的对档率，提高可靠性。
- 单向设计适合直流电源和单向信号线保护，钳位电压低，能有效限制过电压峰值，减小后端器件应力。
- 小型 SOD-123FL 封装利于紧凑布局和自动贴装，适配消费电子、通信与工业设备。
- 宽温工作范围和良好高温特性，适合车载/工业级等高温场景。
四、典型应用
- 电源输入端过压/浪涌保护（DC 供电系统）
- 通信接口及数据线（如 PoE 辅助线路）的瞬态浪涌抑制
- 工业控制设备、测量仪器、车载电子防护
- 需满足ESD、雷击或电磁脉冲防护的场景
五、封装与可靠性
SOD-123FL 封装体积小、热阻低，利于热量散逸；在设计时应保证良好的接地和散热通道以释放瞬态能量。推荐器件靠近被保护节点放置，减少走线电感，保证响应速度与钳位效果。
六、选型与使用建议
- 确认系统工作电压与 Vrwm（22V）匹配；单向器件适用于正向受压场合，若为双向系统请选用对应型号。
- 注意峰值功率 Ppp 与脉冲次数限制，避免长期超出规格的冲击。
- PCB 布局上建议靠近保护端口放置，并保证良好地线连接与散热路径。
- 存储与焊接遵循厂家工艺建议，避免过高回流温度或长时间高温暴露以保护器件性能。
SMF22A 以其小体积、高可靠性和良好高温特性，适合作为中高压直流和信号线的通用瞬态保护器件，能在多种工业与民用场景中提供稳定有效的浪涌抑制。

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.
