SMBJ6.8A TVS二极管(SMB 封装)产品概述

一、产品简介

SMBJ6.8A 是 RUILON(瑞隆源)推出的一款单向瞬态电压抑制器(TVS),适用于保护电源线和信号线免受浪涌与瞬态过压损害。该器件为单向极性,封装为 SMB,具有高脉冲功率吸收能力与宽工作温度范围,适配工业级和消费级多种应用场景。描述:校验通过!

二、主要电气参数

  • 反向截止电压(Vrwm):5.8 V(推荐工作反向电压)
  • 击穿电压(Vbr):6.45 V(标称击穿点)
  • 钳位电压(Vc):约 10.5 V(在额定脉冲条件下)
  • 峰值脉冲电流(Ipp):57 A
  • 峰值脉冲功率(Ppp):600 W(按 10/1000 μs 波形)
  • 工作温度范围:-55 ℃ 至 +150 ℃
  • 类型:单向 TVS,SMB 封装

三、主要特性与优势

  • 高能量吸收:600 W(10/1000 μs)能力,可吸收典型雷击或开关瞬态能量。
  • 低钳位电压:在 57 A 峰值脉冲条件下钳位约 10.5 V,有效保护后端器件免受过压。
  • 宽温度范围:-55 ℃ 到 +150 ℃,适合严苛环境与工业应用。
  • SMB 封装:适合表面贴装,兼顾散热和自动化装配;尺寸适中,便于在电源轨和接口处布局。
  • 单向结构:对直流电源线(比如 5 V 或 6 V 轨)提供针对性保护,响应速度快。

四、典型应用场景

  • 电源输入保护:适用于 5 V / 6 V 直流电源轨的浪涌与反向瞬态抑制。
  • 通讯与接口保护:USB、串口、以太网交换机等需要抗突发浪涌的接口。
  • 工业控制设备:PLC、电机驱动器等易受雷击或电磁脉冲影响的系统。
  • 消费电子与汽车电子(视系统要求与认证而定)。

五、封装、可靠性与质量说明

SMB(表面贴装)封装利于流水线贴装与回流焊工艺,具备良好热特性。产品通过检验(校验通过),制造与检验流程可确保一致性与长期可靠性。推荐在设计阶段考虑器件的热阻与浪涌能量分配,适当留出散热空间并配合阻尼元件以延长寿命。

六、使用建议与注意事项

  • 工作电压选择:Vrwm=5.8 V,适用于接近 5–6 V 的电源轨,超过此范围需选型更高 Vrwm 的器件。
  • 布局建议:尽量将 TVS 靠近受保护端口或电源入点,走线短且粗,减小寄生电感以得到更低的有效钳位。
  • 热管理:高能量吸收时会产生热量,需保证良好散热路径并避免长期在脉冲功率接近极限条件下工作。
  • 串联阻抗:在高能量环境下,结合串联电阻或其他限制元件可分担冲击能量,提高系统可靠性。
  • 安全与认证:若用于汽车或特殊行业,请另行确认相应认证与温度/振动要求。

七、总结与推荐

SMBJ6.8A(RUILON,SMB 封装)以其 600 W(10/1000 μs)、57 A 峰值脉冲能力、低钳位电压与宽温度范围,为 5–6 V 轨道及接口提供高效的瞬态过压保护。适用于要求高能量吸收和可靠性的工业与民用场景。设计时建议按上述布局与热管理建议实施,以发挥器件最佳保护效果。若有更高工作电压或更低钳位要求,可提供替代型号选型支持。

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
