BV-SMBJ6.5CA 瞬态抑制二极管(TVS)产品概述

BV-SMBJ6.5CA是一款双向瞬态抑制二极管(TVS),由Bencent(槟城)推出,采用SMB(DO-214AA)表面贴装封装,专为低电压电子系统的瞬态过压防护设计,可有效抑制雷击、ESD(静电放电)、开关浪涌等瞬态脉冲干扰,保护敏感电路免受损坏。

一、产品定位与核心价值

作为小体积、高功率密度的TVS器件,BV-SMBJ6.5CA的核心定位是低电压系统的双向过压防护,核心优势包括:

  1. 双向防护能力,同时应对正负瞬态脉冲;
  2. SMB封装适配高密度PCB设计,满足小型化设备需求;
  3. 宽温范围与高浪涌耐受,覆盖工业、汽车等恶劣环境;
  4. 符合IEC电磁兼容标准,可靠性有明确保障。

二、关键电性能参数深度解读

BV-SMBJ6.5CA的参数针对低电压系统优化,核心指标如下:

2.1 防护电压参数

  • 反向截止电压(Vrwm):6.5V
    正常工作时允许的最大反向电压,需高于系统工作电压(如3.3V、5V),避免器件误导通,确保系统功耗稳定。
  • 击穿电压(Vbr):7.22V
    反向电压超过Vrwm后,器件开始击穿导通的阈值,是截止到防护状态的过渡点,与Vrwm的差值符合TVS典型设计逻辑。
  • 钳位电压(Vc):11.2V
    峰值脉冲下的最大钳位电压,是防护核心指标——需确保被保护元件耐压高于此值(如12V元件可安全匹配),有效限制浪涌冲击。

2.2 浪涌耐受能力

  • 峰值脉冲电流(Ipp):53.6A
    10/1000μs标准浪涌波形下的峰值电流,可应对常见雷击、开关浪涌事件。
  • 峰值脉冲功率(Ppp):600W
    与Vc、Ipp满足Ppp≈Vc×Ipp(11.2V×53.6A≈600W),直观反映浪涌功率耐受能力。

2.3 功耗与漏电流

  • 反向漏电流(Ir):500μA
    Vrwm下的反向漏电流,属于TVS合理范围,不增加系统额外功耗,对低功耗电路友好。

三、封装与机械特性

BV-SMBJ6.5CA采用SMB封装(JEDEC DO-214AA),机械优势明显:

  1. 小体积:尺寸约2.3mm×5.2mm×1.0mm,适配高密度PCB布局;
  2. 表面贴装:支持自动化贴装,生产效率高;
  3. 双向引脚:无需区分正负极,安装便捷。

四、环境适应性与可靠性

4.1 宽温工作范围

  • 温度:-55℃~+150℃
    覆盖工业级、汽车级需求,可应用于高温(汽车发动机舱)、低温(北方户外设备)等场景。

4.2 电磁兼容防护

  • 标准:IEC 61000-4-2
    符合静电放电防护标准,应对人体放电(HBM)、机器放电(MM)等ESD事件,降低电路损坏风险。

4.3 长期可靠性

Bencent采用成熟工艺,确保多次浪涌后参数稳定,漏电流、钳位电压无明显漂移,满足长期使用需求。

五、典型应用场景

BV-SMBJ6.5CA适配多领域低电压系统:

  1. 低电压电源:3.3V/5V嵌入式系统、物联网节点的浪涌防护;
  2. 高速信号:USB、HDMI、以太网接口的ESD与浪涌防护;
  3. 汽车电子:车载娱乐、胎压传感器、ECU辅助电路防护;
  4. 工业控制:PLC、工业传感器、电机驱动电路防护;
  5. 消费电子:智能手机、平板充电/数据接口防护。

六、总结

BV-SMBJ6.5CA凭借6.5V截止电压、11.2V钳位电压、600W峰值功率,完美适配低电压系统防护;SMB封装与宽温能力,覆盖工业、汽车、消费电子等领域;符合IEC标准的可靠性,为敏感电路提供稳定瞬态防护。

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
