BV-SMBJ15CA 产品概述

一、产品简介

BV-SMBJ15CA 是 Bencent(槟城)推出的一款 SMB 封装、双向瞬态浪涌抑制器(TVS 二极管)。其设计针对车辆电源、工业控制、电信接口和数据线路等易遭受静电放电(ESD)与浪涌干扰的场合,提供快速、可靠的过压钳位保护,保护下游敏感器件和电路板免受瞬态高能脉冲的破坏。

二、主要参数

  • 极性:双向
  • 反向截止电压 Vrwm:15 V
  • 击穿电压 Vbr:18.5 V
  • 钳位电压 Vclamp(峰值):24.4 V
  • 峰值脉冲电流 Ipp:24.6 A(10/1000 μs)
  • 峰值脉冲功率 Ppp:600 W(10/1000 μs)
  • 反向电流 Ir:1 μA(常温)
  • 工作温度:-55 ℃ ~ +150 ℃
  • 防护等级:满足 IEC 61000-4-2 标准(ESD 抗扰)
  • 封装:SMB

三、核心特点

  • 高能量吸收能力:在 10/1000 μs 浪涌波形下可承受 600 W 峰值功率和 24.6 A 峰值电流,适合处理较长时间尺度的脉冲能量。
  • 低漏流与稳定钳位:Typ. 1 μA 的低反向电流与约 24.4 V 的钳位电压,能在保护同时减少对正常工作电压的影响。
  • 宽温度范围:-55℃ 至 +150℃ 的工作温度,适应严苛环境。
  • 双向保护:适用于交流或可能反向极性的线路,简化设计。
  • SMB 封装:兼顾功率散热与 PCB 布局便捷性,适合表面贴装工艺。

四、典型应用场景

  • 汽车电子(车载总线、传感器接口、充电系统的瞬态保护)
  • 工业控制与自动化(电源线、I/O 接口、现场总线)
  • 通信设备(基站、电信端口、以太网接口的过压保护)
  • 消费电子与电源模块(适配器输出防护、充电站防浪涌)

五、封装与安装建议

  • 建议将 BV-SMBJ15CA 紧靠被保护的接口或器件布局,最短保护路径可降低寄生感抗。
  • PCB 走线应尽量宽且短,以利于热量分散与降低串联阻抗;对高能量冲击场合可增加铜厚或加焊盘散热。
  • 使用常规回流焊工艺贴装,注意遵循器件厂家推荐的焊接曲线与回流温度限制。
  • 对于关键应用推荐并联或级联保护方案时,需注意能量分配与器件一致性。

六、可靠性与认证

BV-SMBJ15CA 符合 IEC 61000-4-2 静电放电抗扰标准,器件在广泛温度下具有良好的稳定性与重复浪涌承受能力,适合长期运行环境。对于特定可靠性要求(如高加速寿命试验或车规级认证),建议与供应商确认具体测试报告与批次资料。

七、选型与注意事项

  • 若系统工作电压接近或高于 Vrwm(15 V),应重新评估钳位与泄漏影响;对 12 V 系统是常见选择,但对更高母线电压需选更高 Vrwm 的型号。
  • 关注实际应用中的浪涌波形与能量(10/1000 μs、8/20 μs 等),以确保器件额定能力满足需求。
  • 在并联使用时需考虑到电流共享与热失控问题。

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
