SMBJ6.5CA 双向瞬态抑制二极管(TVS)产品概述

一、产品核心定位与应用领域

SMBJ6.5CA是一款双向瞬态抑制二极管(TVS),核心功能是为电子设备提供静电放电(ESD)和浪涌过压防护,是集成电路(IC)、MOS管、传感器等敏感元器件的关键防护器件。其设计逻辑是:在极短时间内(纳秒级)抑制过压脉冲,将电压钳位在安全范围,避免后级电路因过压损坏。

该器件的典型应用覆盖多领域:

  • 消费电子:智能手机、平板、笔记本的USB/HDMI接口防护,应对插拔静电、电源浪涌;
  • 通信设备:路由器、交换机的以太网端口、射频接口浪涌防护,抵御雷击感应浪涌;
  • 工业控制:PLC、传感器、工业电源的输入输出端ESD防护,适应复杂工业电磁干扰;
  • 小型终端:智能穿戴、物联网设备的低电压电路防护,匹配紧凑空间需求。

二、关键电气参数及实际意义

SMBJ6.5CA的参数直接决定防护能力,各参数的实际价值如下:

  1. 极性:双向
    可同时抑制正、负方向过压脉冲,无需额外反向保护电路,简化PCB布局,降低设计成本。

  2. 反向截止电压(Vrwm):6.5V
    设备正常工作时,器件处于截止状态的最大电压(漏电流极小)。若设备工作电压为5V,6.5V的Vrwm可确保器件不干扰正常电路,仅在过压时启动保护。

  3. 击穿电压(Vbr):7.22V
    过压超过该值时,器件击穿导通,将过压能量泄放至地,启动防护机制。此值略高于Vrwm,保证“正常工作→保护启动”的切换可靠性。

  4. 钳位电压(Vc):11.2V
    峰值脉冲电流下,器件两端的最大电压。该值越低,对后级敏感器件的保护效果越好——11.2V可避免IC因过压击穿损坏。

  5. 峰值脉冲功率(Ppp):600W@10/1000μs
    10/1000μs标准浪涌波形(10μs上升沿、1000μs下降沿)下,器件可承受的最大脉冲功率。600W足够应对日常环境中的多数浪涌(如雷击感应、电源开关浪涌)。

  6. 峰值脉冲电流(Ipp):53.57A
    与Ppp、Vc关联(Ppp=Vc×Ipp),是器件可泄放的最大脉冲电流,直接反映抗浪涌能力。

  7. 反向漏电流(Ir):500μA
    6.5V截止电压下的漏电流,值极小,可忽略对正常电路的影响,保证低功耗特性。

三、封装与品牌特性

  1. 封装:SMB(DO-214AA)
    贴片式SMB封装尺寸紧凑(约2.5mm×3.5mm),适合高密度PCB设计;支持自动化贴装,生产效率高,适配小型化电子设备的空间需求。

  2. 品牌:LGE(鲁光)
    LGE是国内知名半导体厂商,SMBJ6.5CA经过严格可靠性测试(温度循环、湿度测试、浪涌冲击测试),符合IEC 61000-4-2(ESD)、IEC 61000-4-5(浪涌)等行业标准,质量稳定可靠,性价比优势明显。

四、产品优势总结

SMBJ6.5CA的综合优势使其成为中低压电路防护的优选:

  • 双向防护:无需额外反向保护,电路设计更简洁;
  • 低钳位电压:11.2V可有效保护敏感IC;
  • 高脉冲耐受:600W峰值功率应对常见浪涌冲击;
  • 小封装适配:SMB封装适合小型化、高密度设计;
  • 可靠性价比:LGE品牌质量稳定,成本可控。

综上,SMBJ6.5CA是一款性能均衡、适配性强的TVS器件,可满足多数中低压电子设备的ESD/浪涌防护需求。

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
