BSD5C121V-ES 产品概述

一、产品简介

BSD5C121V-ES 是 ElecSuper(静芯微)推出的一款单路双向瞬态抑制二极管(ESD TVS),采用 SOD-523 超小封装,专为保护高速数据线和敏感电子元件免受静电放电与瞬态过压冲击设计。器件体积小、响应快,适合空间受限的消费类与工业电子设备。

二、主要技术参数

  • 极性:双向
  • 反向截止电压 Vrwm:12 V
  • 击穿电压:13 V
  • 钳位电压:18 V(峰值)
  • 峰值脉冲电流 Ipp:8 A
  • 峰值脉冲功率 Ppp:200 W(单次脉冲)
  • 反向漏电流 Ir:1 μA
  • 结电容 Cj:6.5 pF
  • 通道数:单路
  • 工作温度范围:-40 ℃ ~ +125 ℃
  • 防护等级:符合 IEC 61000-4-2 ESD 要求
  • 封装:SOD-523
  • 品牌:ElecSuper(静芯微)

三、产品特点

  • 双向保护:可对正负极性瞬变电压同时抑制,适合差分信号线。
  • 低钳位电压:在 8A 脉冲下钳位约 18V,能有效保护下游器件。
  • 小结电容(6.5 pF):在多数接口中对信号完整性影响较小,适用于 USB、音频等高速接口。
  • 低漏电流:1 μA 的低反向电流有利于电池供电与高阻抗电路应用。
  • 紧凑封装:SOD-523 便于 PCB 密集布局与自动化贴装。

四、典型应用

  • USB/HDMI/DP 等接口的静电防护
  • 智能手机、平板、便携式设备 I/O 保护
  • 摄像头模组与传感器信号线保护
  • 工业控制与通讯设备的接口保护

五、布局与使用建议

  • 靠近受保护端口(如连接器)放置,走线尽量短且直接接地以降低回路电感。
  • 对于高速差分信号,需评估 6.5 pF 电容对信号带宽的影响,必要时在 PCB 上做匹配与仿真。
  • 推荐与低阻抗接地平面配合使用,IC 侧接地通过多孔过孔实现良好回流。
  • 焊接时遵循 SOD-523 的回流温度规范,避免长时间高温使器件性能退化。

六、包装与存储

SOD-523 小封装适合贴片生产线,建议在干燥环境中保存,避免潮湿引起吸湿焊接缺陷。订购时请确认完整料号 BSD5C121V-ES 与供应商批次,以便追溯与质量保证。

如需更详细的电气特性曲线、冲击测试波形或推荐 PCB 布局文件,可向 ElecSuper(静芯微)或授权经销商索取完整数据手册与应用笔记。

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
