SMBJ130CA 产品概述
一、产品简介
SMBJ130CA 是东沃（DOWO）推出的一款双向瞬态电压抑制二极管（TVS），用于吸收和钳位瞬态过电压，保护敏感电子元件免受雷击、开关瞬变和感性负载反向峰值电压的破坏。该器件在 10/1000 μs 浪涌条件下可承受高达 600W 峰值脉冲功率，适合各种工业和商业电源与信号保护需求。
二、主要参数与电气特性
- 极性：双向（Bidirectional）
- 反向截止电压 VRWM：130 V
- 击穿电压（典型）：144 V
- 钳位电压 VC（在 Ipp）：209 V
- 峰值脉冲电流 Ipp（10/1000 μs）：2.87 A
- 峰值脉冲功率 Ppp（10/1000 μs）：600 W
- 反向泄漏电流 Ir：1 μA
- 工作温度范围：-55 ℃ ～ +150 ℃
这些参数表明 SMBJ130CA 在高工作电压系统中具有良好的浪涌承受能力与低泄漏特性，钳位电压控制在安全范围内，能有效限制瞬态电压对下游电路的冲击。
三、结构与封装
- 封装类型：SMB（DO-214AA）表面贴装封装，适用于自动化贴装及回流焊工艺。
- 封装优势：体积适中，热阻较低，便于在有限空间内实现有效散热与可靠的机械固定。
- 安装注意：推荐按 PCB 厂家和封装推荐的焊盘布局进行阻焊与过孔设计，确保良好热量传导与可靠焊接。
四、典型应用场景
- 交流/直流电源输入与分配保护
- 工业控制、变频器及驱动器的瞬态抑制
- 通信与数据传输接口保护
- 能源与储能系统的过压防护（如逆变器侧）
- 汽车电子、医疗设备及仪器仪表的局部浪涌防护（在满足系统规范前提下）
五、设计与使用建议
- 在选择 TVS 时，优先确认系统最大工作电压应低于 VRWM，以避免器件持续导通。
- SMBJ130CA 为双向器件，适合交流线路或需双向钳位的场合；若为直流单向场合，可考虑相应单向型号以降低钳位电压。
- 在高能量脉冲应用中，注意为器件提供充分的散热路径（如加大铜箔面积、使用热 vias）。
- 若系统存在重复高能脉冲，需评估器件的寿命和退化，必要时采用并联或级联保护策略并配合熔丝/限流器。
六、采购与选型要点
- 型号：SMBJ130CA，品牌：DOWO（东沃）
- 封装：SMB（DO-214AA）
- 在选型时，核实供应商提供的典型 IV 曲线、钳位测试条件（Ipp 波形与能量）、以及是否通过项目所需的可靠性与环境认证。
- 建议在样机阶段进行实际浪涌测试验证，确保在目标系统条件下达到预期防护效果。
总结：SMBJ130CA 以其 130V 的工作电压、600W 的脉冲承受能力和双向钳位特性，适用于需要中高电压瞬态保护的场合，是工业电源与通信接口等应用中性价比较高的 TVS 保护元件。

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.
