BV-SMBJ13CA 产品概述

一、产品简介

BV-SMBJ13CA 是 Bencent(槟城)推出的一款双向瞬态抑制二极管(TVS)。器件采用 SMB 表面贴装封装,针对瞬态过压和静电放电(ESD)事件提供快速响应和高能量吸收能力,适用于需要对电源总线、信号线或通信接口进行保护的场合。

二、主要参数

  • 极性:双向
  • 反向截止电压 Vrwm:13 V
  • 击穿电压(典型):14.4 V
  • 钳位电压(典型):21.5 V
  • 峰值脉冲电流 Ipp:28 A
  • 峰值脉冲功率 Ppp:600 W(10/1000 μs 波形)
  • 反向电流 Ir:1 μA(在 Vrwm 条件下)
  • 工作温度范围:-55 ℃ ~ +150 ℃
  • 抗扰度标准:符合 IEC 61000-4-2(ESD 抗扰度)
  • 类型:TVS 瞬态抑制二极管
  • 封装:SMB

三、特性与优势

  • 双向设计:可承受正负极性瞬态脉冲,适用于极性可能反转的电路,如交流信号线、差分总线或双向电源。
  • 高能量吸收:在 10/1000 μs 波形下可提供 600 W 的峰值脉冲功率,能有效吸收由雷击或开关瞬变引起的大能量脉冲。
  • 低泄漏电流:典型反向漏电仅 1 μA,有助于在待机或低功耗应用中降低静态功耗。
  • 快速响应:TVS 器件在瞬态到来时能在纳秒级内启动钳位,保护后级敏感器件。
  • 宽温度范围与工业级可靠性:-55 ℃ 至 +150 ℃ 的额定温度,适应严苛环境工作。

四、典型应用

  • 汽车 12 V 系统的瞬态保护(如电源输入、点火噪声抑制)
  • 通信接口与数据线保护(RS-485、CAN 总线等需考虑电压幅值时)
  • 电源模块与 DC-DC 转换器的输入端防护
  • 工业控制、仪器仪表及电源接入端的雷电和浪涌防护
  • 以太网受限场合或其他需要双向保护的信号链路

五、封装与可靠性

SMB 封装兼具热性能与可焊性,适合波峰或回流焊工艺,便于自动化贴装。器件的温度与电能吸收指标适用于工业与车规级应用,但在长期高能量冲击场合建议配合适当的热散布设计与过流保护措施以保证寿命。

六、设计与使用建议

  • 布局:将 BV-SMBJ13CA 尽量靠近被保护端口或连接器,走线短且宽以降低感抗与寄生电阻。
  • 热管理:对于可能承受频繁浪涌的应用,注意在 PCB 上提供足够的铜皮和过孔以利散热。
  • 额外保护:对于高能量或持续冲击场景,可与熔断器、串联阻抗或多个 TVS 并联(需均流考虑)组合使用。
  • 测试条件:钳位电压与功率指标基于标准测试波形(10/1000 μs),实际电路中的钳位电压会受回路阻抗影响,应在目标系统中验证实际性能。

七、订购与支持

BV-SMBJ13CA 由 Bencent(槟城)生产,封装为 SMB。采购或大量应用前建议向供应商索取完整数据手册、器件的典型波形、可靠性试验报告和元件代号,以便在特定应用中进行定制化验证和符合性评估。若需替代型号或并联/串联方案建议,可联系技术支持获取更多系统级保护设计建议。

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
