SMBJ11CA瞬态抑制二极管(TVS)产品概述

一、产品基本信息与定位

SMBJ11CA是RUILON瑞隆源推出的一款双向瞬态抑制二极管(TVS),核心作用是快速抑制电子电路中的瞬态过压干扰(如静电放电、电快速瞬变脉冲群等),保护敏感元器件免受损坏。其采用SMB封装(DO-214AA),属于表面贴装小型封装,适配高密度PCB设计,广泛覆盖工业、通信、消费电子等低压电路防护场景。

二、核心电气参数解析

SMBJ11CA的参数针对12V级低压电路优化,关键指标清晰指向防护性能:

  1. 反向截止电压(Vrwm):11V
    即器件正常工作时可承受的最大反向直流电压,确保电路在额定电压下无额外漏电流,不影响系统稳定运行。
  2. 击穿电压(Vbr):14V
    反向偏置下器件开始导通的电压阈值,当电路电压超过此值时,TVS快速击穿,将电压钳位至安全范围。
  3. 钳位电压(Vc):18.2V
    峰值脉冲电流(33A)作用下的两端电压,是保护敏感元件的核心参数(需确保Vc低于后端元件最大耐压)。
  4. 峰值脉冲电流(Ipp):33A
    10/1000μs脉冲波形下的最大耐受电流,可应对较强瞬态冲击(10/1000μs为行业标准脉冲:上升沿10μs,半峰值宽度1000μs)。
  5. 峰值脉冲功率(Ppp):600W@10/1000μs
    体现器件的脉冲功率耐受能力,可有效吸收瞬态浪涌能量。
  6. 反向漏电流(Ir):1μA
    反向截止电压下的漏电流极小,不干扰电路正常工作,反向截止性能稳定。
  7. 工作温度范围:-55℃~+150℃
    宽温设计覆盖工业级极端环境(如户外设备、高温车间),性能无衰减。

三、封装与可靠性设计

SMBJ11CA采用SMB封装(DO-214AA),尺寸紧凑(约2.5mm×4.0mm),适配自动化贴装,适合高密度PCB布局。可靠性方面:

  • 符合**IEC 61000-4-4(电快速瞬变脉冲群EFT)和IEC 61000-4-2(静电放电ESD)**标准,可有效抑制这两类常见干扰;
  • 封装工艺抗机械应力能力强,批量应用中一致性稳定;
  • 宽温范围通过严格环境测试,满足工业级可靠性要求。

四、典型应用场景

因低压防护、小封装、宽温等特点,SMBJ11CA广泛用于:

  1. 工业控制:PLC、传感器模块、工业机器人I/O接口,应对车间电快速瞬变干扰;
  2. 通信设备:路由器、交换机、光模块的电源/信号端口,抵御静电和线路浪涌;
  3. 消费电子:智能家居(智能插座、传感器)、可穿戴设备(智能手表)的接口防护,适配小型化需求;
  4. 低压电源:12V直流电源输出端,防止浪涌损坏MCU、传感器等敏感元件。

五、品牌与技术优势

RUILON瑞隆源作为专业保护器件厂商,SMBJ11CA具备:

  • 参数一致性:批量生产离散性小,防护效果稳定;
  • 成本效益:成熟封装工艺降低成本,适合大规模应用;
  • 技术支持:提供电路防护方案设计,帮助客户优化防护效率。

SMBJ11CA是一款性能稳定、适配性强的双向TVS器件,可满足多领域低压电路的瞬态过压防护需求,是工业、通信、消费电子等场景的优选元件。

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.

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
