SMBJ10CA 产品概述
一、产品简介
SMBJ10CA 是 RUILON（瑞隆源）推出的一款双向瞬态电压抑制二极管（TVS），采用 SMB（DO-214AA）表面贴装封装。器件专为抑制瞬态过电压、吸收雷击浪涌和开关瞬变设计，广泛用于工业、通信、电源及汽车电子等需要对导线端口、输入输出接口和电源总线进行过电压保护的场合。
二、主要电气参数
- 极性：双向（适用于交流或对称脉冲保护）
- 反向工作电压 Vrwm：10 V
- 击穿电压 VBR：12.8 V（典型/标称）
- 钳位电压 Vc：17 V（在峰值脉冲电流条件下）
- 峰值脉冲电流 Ipp：35.3 A（对应 10/1000 μs 波形）
- 峰值脉冲功率 Ppp：600 W（10/1000 μs）
- 反向电流 Ir：5 μA（在 Vrwm 条件下）
- 工作温度范围：-55 ℃ 至 +150 ℃
- 符合抗扰度标准：IEC 61000-4-4（EFT）、IEC 61000-4-2（ESD）
三、封装与机械特性
SMB（DO-214AA）封装适合自动贴装与回流焊工艺，具有良好的热量散发能力和机械强度，便于在受限空间内实现高能量吸收器件的部署。推荐将 TVS 尽可能靠近被保护的连接器或器件布局，以最小化环路电感。
四、典型应用场景
- 12 V/24 V 电源总线过压保护（汽车电源、工业电源）
- 通信接口和数据线防护（以太网、RS-485 等）
- 电源适配器、充电桩、逆变器输入端的浪涌吸收
- PCB 端口、连接器及模块化产品的外部雷电与开关瞬变防护
五、选型与设计要点
- 工作电压匹配：Vrwm（10 V）应高于线路正常工作电压，但低于被保护器件可承受的最大电压。
- 钳位电压评估：钳位电压 17 V 意味着在冲击发生时被保护侧电压不会超过此值（受测试条件限制），需确保该电压对下游部件安全。
- 功率与脉冲能力：600 W/10/1000 μs 能有效吸收一次性高能浪涌，若存在频繁冲击或更大能量，需采用并联或更高等级型号。
- 极性选择：双向器件适合 AC 或双向脉冲环境；若仅用于单向直流线路，可考虑单向 TVS 以获得更低的钳位电压。
六、安装与可靠性建议
- 布局：靠近受保护端（输入端口或连接器）并尽量缩短走线长度与回路电感。
- 焊接：遵循回流焊温度曲线与制造商推荐的工艺参数，避免长时间过高温度。
- 环境：工作温度高达 150 ℃，适合高温环境，但长期高温下应考虑器件老化与热管理。
- 测试与验证：在最终系统中进行 ESD/EFT 和雷击仿真测试，验证实际钳位与能量吸收表现。
SMBJ10CA 以其 10 V 级别的工作电压、600 W 的脉冲功率和符合 IEC 抗扰度标准的特性，是在中低电压系统中实现稳健瞬态保护的可靠选择。根据实际应用场景做好电压、钳位和热管理匹配，即可发挥其最佳保护效果。

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.
