SMBJ6.8CA — 双向瞬态抑制二极管（TVS）产品概述
一、产品简介
SMBJ6.8CA 是 RUILON（瑞隆源）出品的一款双向 TVS（二极管型瞬态电压抑制器），采用 DO-214AA（SMB）封装，专为瞬态过电压、静电放电（ESD）与浪涌冲击保护设计。器件响应快、能量吸收能力强，适合工业、通信、消费电子及汽车等需稳健浪涌保护的场合。
二、主要参数
- 极性：双向（Bidirectional）
- 反向截止电压 Vrwm：5.8 V
- 击穿电压（典型）：7.14 V
- 钳位电压 Vc：约 10.5 V（在峰值脉冲电流 Ipp 条件）
- 峰值脉冲电流 Ipp：57 A（10/1000 μs 波形）
- 峰值脉冲功率 Ppp：600 W（10/1000 μs）
- 反向漏电流 Ir：1 mA（在 Vrwm 条件下）
- 工作温度：-55 ℃ 至 +150 ℃
- 封装：DO-214AA（SMB）
三、关键特性
- 双向抑制：可在正负极性瞬态下工作，无需外加极性选择，适用交流或双向脉冲保护。
- 高能量吸收：600 W（10/1000 μs）峰值功率与 57 A 峰值脉冲电流，可承受工业级浪涌事件。
- 低钳位：在规定脉冲条件下约 10.5 V 的钳位电压，有效保护下游器件免受过压损伤。
- 宽温区可靠性：-55 ~ +150 ℃，满足严苛环境和高温工作需求。
- SMB 封装：利于表面贴装生产，散热良好，机械强度高。
四、典型应用
- 电源输入与总线上浪涌保护（交流/直流）
- 通信接口（串口、CAN、以太网）与数据线过压保护
- 工业控制、PLC、变频器等抗干扰设计
- 汽车电子模块（需评估汽车级认证要求）
- 消费类电子和仪器仪表的端口防护
五、封装与安装建议
- 尽量将 TVS 芯片布置在被保护线与地之间，靠近被保护器件或连接器位置，缩短信号/电源回路走线以降低寄生阻抗。
- 推荐结合熔断器或电流限制器使用，以防长时间大电流对 TVS 造成热应力。
- 焊接时遵循 SMB 封装的回流焊工艺规范，控制焊接与回流温度以保证可靠性。
- 对于高速信号线保护，应评估器件电容对信号质量的影响。
六、可靠性与选型要点
选择 SMBJ6.8CA 时，应确认系统允许的工作电压（Vrwm 5.8 V）与漏电流容忍度（Ir 1 mA）。若系统常态电压接近或超过 Vrwm，请改用更高 Vrwm 规格。对于需汽车 AEC-Q 等级的应用，建议与供应商确认器件认证与 DPA/可靠性测试报告。总体而言，SMBJ6.8CA 在中高能量、双向保护场合表现均衡，是常见的浪涌与静电防护解决方案。

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.
