BSD5A071V35 产品概述

一、产品简介

BSD5A071V35 为单向硅雪崩瞬态电压抑制二极管(TVS),由 BORN(伯恩半导体)生产,采用超小型 SOD-523 封装,专为便携式与基于微处理器的设备提供高效瞬态浪涌与静电放电(ESD)保护。器件工作电压(Vrwm)为 7V,击穿电压(VBR)约 8V,具有低钳位电压与极低泄漏电流,适合对电源与敏感 I/O 端口的保护需求。

二、主要电气参数

  • 极性:单向
  • 反向截止电压 Vrwm:7V
  • 击穿电压 VBR:8V
  • 钳位电压:25V(典型)
  • 峰值脉冲电流 Ipp:15A(8/20μs)
  • 峰值脉冲功率 Ppp:400W(tp = 8/20μs)
  • 反向漏电流 Ir:1μA
  • 结电容 Cj:100pF
  • 防护等级:符合 IEC 61000-4-2、4-4、4-5(ESD、EFT、雷击脉冲等)

三、关键特性与优势

  • 高能量吸收:在 8/20μs 波形下可承受 400W 峰值功率,能可靠吸收短时浪涌能量。
  • 低钳位:典型钳位约 25V,可有效限制受保护节点电压,降低后级元件受击风险。
  • 低漏电:反向漏电仅 1μA,适合低功耗系统。
  • 小体积封装:SOD-523 适合空间受限的便携式设备,如 PDA、可穿戴与移动终端。
  • 符合工业级标准:通过 IEC 61000 系列抗扰度测试,支持接触 ±8kV、空气 ±15kV 等级别的 ESD 防护。

四、典型应用场景

  • 基于微处理器的嵌入式系统与开发板电源保护。
  • 便携式消费电子:PDA、手持终端、蓝牙设备、可穿戴等。
  • I/O 与通信接口保护(非超高速信号)。
  • 电源输入与充电接口的瞬态浪涌抑制。

五、选型与使用建议

  • 工作电压匹配:器件 Vrwm = 7V,适用于 5V/6V 类电源或低压电源线路,避免用于高压系统。
  • 高频/高速信号注意:结电容 100pF 在高带宽信号线上可能引入明显影响,不建议直接用于高速数据线(USB3.0、HDMI 等);用于慢速控制或电源线路更为合适。
  • 放置位置:靠近被保护端口或器件引脚布局,采用最短、最粗的走线连接至地,以降低回路电感并提高保护效率。
  • 散热与脉冲重复:器件额定为短时脉冲能量吸收(8/20μs),不建议用于持续或频繁大幅度冲击场景,应按实际工作环境进行功率与热量余量评估并适当降额使用。
  • 极性识别:单向器件仅在正向瞬态时发挥钳位功能,负向过压场景需选用双向型号或增设其他保护器件。

六、封装与可靠性

SOD-523 封装体积小、适合表面贴装(SMT),便于自动化贴装与小型化设计。BORN 提供的器件通过常见电气稳健性测试,适用于大多数工业与消费级抗干扰设计。使用时注意焊接温度曲线与回流规范,避免因加工造成器件性能下降。

七、总结

BSD5A071V35 是一款面向低压便携设备的高能量 TVS 器件,结合 400W 峰值吸收能力、低钳位和小型 SOD-523 封装,能在有限空间内为电源与敏感节点提供可靠瞬态保护。选用时需关注结电容对信号带宽的影响与脉冲能量的实际使用频率,以确保系统长期稳定与可靠。

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
