SMBJ15CA 产品概述
一、产品简介
SMBJ15CA 是扬杰（YANGJIE）出品的一款双向瞬态电压抑制器（TVS），采用 SMB（DO-214AA）封装，专为保护电子线路免受雷击、浪涌和静电放电等瞬态过电压冲击而设计。其工作电压水平适合 12V 及附近电源和信号总线的过压保护需求，具有快速响应和高能量吸收能力。
二、主要电气参数
- 极性：双向（Bi-directional），适用于交流或双向脉冲抑制场合
- 反向工作电压 Vrwm：15V
- 击穿电压 Vbr：约 18.5V
- 钳位电压 Vc：24.4V（对应测试条件）
- 峰值脉冲功率 Ppp：600W（10/1000 µs 波形）
- 峰值脉冲电流 Ipp：24.6A（10/1000 µs）
- 反向漏电流 Ir：5 µA（常温）
- 工作温度范围：-55℃ ~ +150℃
三、性能特点
- 高能量吸收：600W 峰值脉冲功率，能够吸收工业级浪涌或雷击残余能量。
- 低漏电流：5µA 的低反向电流，有利于不影响低功耗电路长期稳定工作。
- 快速响应：典型 TVS 特性，可在纳秒级别钳制过电压，保护下游元件。
- 双向保护：无需区分极性，适合交流线路或需双向钳位的应用场景。
- 标准封装：SMB（DO-214AA）便于自动化贴装与散热处理。
四、典型应用场景
- 汽车电子 12V/24V 线路的瞬变保护（注意选型时结合车规要求）
- 工业控制设备的电源及信号总线防护
- 电源适配器、逆变器输出侧的浪涌抑制
- 通信设备、接口保护（RS-485、CAN 等需要双向保护的总线）
- 家用电器及楼宇自动化系统的防雷防浪涌设计
五、封装与可靠性注意事项
- 封装：SMB（DO-214AA），适配常见 SMT 与 THR 装配工艺。
- 热管理：高能量吸收时会产生热量，须在 PCB 设计中留出足够铜箔散热区并靠近接地层布线。
- 安装建议：双向器件无极性要求，但需保证焊接可靠并避免与热敏元件并列放置。
- 使用寿命：TVS 为耗散型保护元件，频繁或超额浪涌后性能可能退化，关键系统建议配合熔断器或自恢复保险丝使用。
六、选型与应用提示
- 若保护对象为直流单向电源且对正向压敏性要求高，可优先考虑单向 TVS。
- 确认系统最大允许钳位电压是否低于被保护器件承受极限（此器件钳位约 24.4V）。
- 根据实际波形与能量（10/1000 µs 仅为常见测试波形），核算所需能量余量并考虑环境温度对功率的影响。
七、小结
SMBJ15CA 为一款适用于中等能量浪涌防护的双向 TVS，适配 12V 类电源与多种信号总线保护需求。凭借 600W 的吸收能力、低漏电与 SMB 可靠封装，能够在需要快速钳制瞬态过电压的场景中提供有效保护。选型时请结合实际系统允许的最大钳位电压、热管理及浪涌能量要求，保证长期稳定运行。

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.
