BV-SMBJ7.5CA TVS瞬态抑制二极管产品概述

一、产品定位与核心属性

BV-SMBJ7.5CA是Bencent(槟城)品牌推出的双向瞬态抑制二极管(TVS),专为低电压电路的瞬态过压防护设计,采用SMB(DO-214AA)表面贴装封装,体积紧凑(约3.0×2.0×1.5mm),适配高密度PCB布局。该器件核心功能是快速抑制静电放电(ESD)、雷击浪涌等瞬态过压,保护MCU、传感器、通信接口等敏感元件免受损坏,是低电压系统过压防护的高性价比选择。

二、关键电气参数深度解析

该器件参数精准匹配低电压防护需求,核心参数及实际意义如下:

  1. 极性与截止特性:双向极性设计,可同时防护正负瞬态过压;反向截止电压(Vrwm)7.5V,即正常工作时可承受的最大反向电压,确保5V~7.5V低电压系统无异常导通(反向漏电流Ir仅100μA,符合低功耗要求)。
  2. 导通与钳位能力:击穿电压(Vbr)9.21V,当瞬态过压超过该值时,器件快速导通(TVS典型响应时间<1ns);钳位电压(Vc)12.9V,可将过压峰值钳位在安全范围,避免后级元件过压损坏。
  3. 脉冲耐受强度:峰值脉冲功率(Ppp)600W(10/1000μs波形)、峰值脉冲电流(Ipp)46.6A(同波形),可有效承受雷击浪涌、ESD等强瞬态脉冲,防护等级符合IEC 61000-4-2静电放电标准。
  4. 宽温工作范围:-55℃~+150℃的温度区间,覆盖工业、汽车等极端环境应用场景。

三、封装与可靠性设计

  1. SMB封装优势:采用DO-214AA表面贴装封装,引脚间距合理,兼容自动化贴装工艺;尺寸小巧,适合消费电子、通信设备等高密度PCB设计。
  2. 可靠性保障:
    • 宽温范围满足工业级(-40℃+125℃)及汽车级(-55℃+150℃)温度要求;
    • 内部玻璃钝化工艺,提升反向耐压稳定性与抗浪涌能力;
    • 符合IEC 61000-4-2标准,可抵御人体接触静电(接触放电8kV、空气放电15kV)。

四、典型应用场景

BV-SMBJ7.5CA适配多领域低电压系统防护,典型应用包括:

  1. 消费电子:手机、平板、笔记本的USB接口、HDMI接口、音频接口防护,抵御静电放电与插拔浪涌;
  2. 工业控制:PLC模块、传感器节点、RS485/RS232通信接口的电源/信号线路防护,适应工业现场宽温环境;
  3. 汽车电子:车载传感器(胎压监测、摄像头)、辅助电路低电压模块防护,符合汽车级温度要求;
  4. 通信设备:路由器、交换机、基站的RJ45接口、电源输入线路防护,提升抗ESD与浪涌能力。

五、品牌与质量说明

Bencent(槟城)作为专业元器件制造商,在TVS领域拥有成熟研发生产体系:

  • BV-SMBJ7.5CA通过严格参数一致性测试,批量产品性能稳定;
  • 符合RoHS环保标准,无铅无卤,适配绿色电子产品设计;
  • 器件寿命长,可承受多次瞬态脉冲冲击,降低系统维护成本。

总结:BV-SMBJ7.5CA兼具宽温适应性、强脉冲耐受能力与紧凑封装,可广泛应用于消费电子、工业控制、汽车电子等领域的低电压过压防护,有效提升电子系统的可靠性与抗干扰能力。

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
