SMBJ13CA — 双向瞬态抑制二极管产品概述
一、产品概述
SMBJ13CA 是 RUILON（瑞隆源）推出的一款双向 TVS（瞬态电压抑制）二极管，封装为 SMB（DO-214AA），专为保护敏感电子线路免受静电放电（ESD）、电快速瞬变（EFT）及雷击感应脉冲等瞬态过电压而设计。器件工作温度范围宽（-55℃~+150℃），适合工业级与通信、电源等应用场景。
二、主要性能参数
- 极性：双向
- 反向截止电压 Vrwm：13 V
- 击穿电压 Vbr：16.5 V
- 钳位电压 Vc（典型）：21.5 V
- 峰值脉冲电流 Ipp：27.9 A（10/1000 µs）
- 峰值脉冲功率 Ppp：600 W（10/1000 µs）
- 反向电流 Ir：1 μA（常温）
- 工作温度：-55 ℃ ～ +150 ℃
- 防护等级/标准：符合 IEC 61000-4-4（EFT）、IEC 61000-4-2（ESD）
三、主要特性与优势
- 双向结构可同时抑制正负向瞬态，适用于交流或双向信号线保护。
- 低泄漏电流（Ir≈1 μA），对电路静态功耗影响小。
- 钳位电压低（21.5 V），在瞬态发生时能有效限制电压幅值，保护后级器件。
- 高冲击能力（600 W /10/1000 µs，Ipp 27.9 A）适合雷击感应与大能量脉冲防护。
- 宽工作温度与工业级封装，可靠性高，适用于严苛环境。
四、典型应用场景
- 通信接口（以太网、串口等）和信号线浪涌保护；
- 电源输入端的浪涌抑制；
- 工业控制设备、PLC、变频器的EMC防护；
- 通信基站、路由器及户外设备的防雷防静电；
- 消费类电子中对接口防护要求较高的场合。
五、封装与可靠性
SMB（DO-214AA）封装方便通过波峰/回流焊或手工焊接加工，具备良好散热与机械强度。器件经过IEC 61000-4-2/4-4等级试验验证，适用于要求ESD与EFT保护的产品设计。
六、选型与使用建议
- 若线路为单向直流保护，应选用单向 TVS；双向线路（交流或差分信号）推荐 SMBJ13CA。
- 钳位电压应低于被保护器件最大承受电压余量；21.5 V 钳位适合大多数 24 V 类系统或接口。
- 注意并联或串联使用时的热耗散与功率分布，确保Ppp与Ipp不被超载。
- 焊接时遵循厂商的温度曲线，避免过热影响可靠性。
七、安装与维护
建议靠近被保护端口布置、短引线连接以降低寄生电感。为保证长期可靠性，应避免在超过额定工作温度和重复冲击下长期运行，必要时配合保险或限流元件共同使用以提升系统鲁棒性。

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.
