BSD3A361V 产品概述

一、产品简介

BSD3A361V 是 BORN(伯恩半导体)出品的一款单向 TVS(二极管)瞬态抑制器,专为接口与线路的静电放电(ESD)、电快速瞬变(EFT)和雷击/浪涌冲击保护而设计。器件采用小型 SOD-323 封装,体积小、响应快、适合贴片自动化生产与空间受限的电路板使用,常用于接口保护材料与各类输入/输出端口防护。

二、核心参数

  • 极性:单向(unidirectional)
  • 反向稳态电压 Vrwm:36 V
  • 钳位电压(Vcl):约 60 V(于规范脉冲条件下)
  • 峰值脉冲电流 Ipp:4 A @ 8/20 μs
  • 峰值脉冲功率 Ppp:240 W @ 8/20 μs
  • 反向漏电流 Ir:典型 1 μA(在 Vrwm 条件下)
  • 结电容 Cj:约 25 pF
  • 防护等级:符合 IEC 61000-4-2(ESD)、IEC 61000-4-4(EFT)、IEC 61000-4-5(浪涌)
  • 封装:SOD-323
  • 类型:TVS 二极管(ESD 静电保护管)

三、主要特性与优势

  • 响应速度快:典型 TVS 响应用于纳秒级,能迅速钳位过冲电压,保护后端器件免受瞬态能量损伤。
  • 低漏电流:Ir 约 1 μA,可在不显著增加静态功耗的情况下长期并接在线路上。
  • 适中结电容:约 25 pF,兼顾高频性能和能量承受能力,适用于多数数字与模拟接口保护(对极高速差分接口请选择更低电容型号)。
  • 高脉冲承受能力:在标准 8/20 μs 测试波形下可承受 4 A 峰值脉冲电流及 240 W 峰值功率,钳位电压约 60 V,能有效吸收常见浪涌与静电冲击能量。
  • 小型封装:SOD-323 适合空间受限设计,便于贴片生产与密集布线。

四、典型应用场景

  • USB、串口、GPIO 等各种外部接口的静电与瞬态保护(视具体速率与电容需求选择)
  • 电源输入与保护线路(DC 线、监控回路,最高工作电压不超过 36 V)
  • 工业控制、通信设备、消费电子接口保护
  • PCB 上装置靠近连接器或外部暴露的信号引出点,作为第一道保护元件

五、封装与布板建议

  • 尽量将 BSD3A361V 放置在被保护端口或连接器的靠近位置,缩短受保护引脚到 TVS 的走线长度以减少感性与阻抗影响。
  • 将 TVS 的地端与 PCB 的接地平面直接焊接,使用宽而短的回流路径降低地回路阻抗。
  • 单向器件需注意极性,通常阴极(带标记端)接到被保护信号线,阳极接地(请按产品数据手册标识安装)。
  • 对于差分高速信号或对电容敏感的接口,建议在选型时比较 Cj 值或采用专门的低电容 TVS。

六、注意事项与选型建议

  • 若线路为交流或两端可能出现正反向瞬态,考虑使用双向 TVS;本型号为单向,仅适合有明确极性的直流/信号线路。
  • 若保护对象为极高速差分接口(如高速 USB、HDMI 等),请评估 25 pF 的结电容是否满足信号完整性要求,必要时选用更低电容型号。
  • 尽量遵循厂商推荐的回流焊接温度曲线和湿敏等级规范,避免因不当回流条件或潮湿造成器件失效。
  • 在实际系统中,需参考器件完整数据手册的测试条件与典型曲线,验证钳位电压与能量吸收能力是否满足系统容限。

七、合规与可靠性

BSD3A361V 符合 IEC 61000-4-2 / 4-4 / 4-5 等常见工业级抗扰度标准,适合用于有一定静电与瞬态冲击风险的应用环境。结合适当的 PCB 布局与接地设计,能显著提高系统的抗扰度与产品可靠性。

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
