SLMESD5V0D9-ES 产品概述

一、产品简介

SLMESD5V0D9-ES 是静芯微(ElecSuper)推出的一款单路单向 TVS 抑制二极管,专为 5V 供电与信号线的瞬态过压保护设计。器件采用 SOD323 小封装,响应迅速、体积小巧,适用于对空间和成本敏感的消费、工业与通信类设备。

二、关键性能

  • 极性:单向
  • 反向工作电压 Vrwm:5V(适配典型 5V 电源和 I/O 保护)
  • 击穿电压 Vbr:6.5V
  • 钳位电压:9V(在脉冲条件下有效限制峰值电压)
  • 峰值脉冲电流 Ipp:30A(8/20µs)
  • 峰值脉冲功率 Ppp:450W(8/20µs)
  • 反向漏电流 Ir:1µA(常温条件)
  • 通道数:单路
  • 工作温度:-40℃ ~ +125℃
  • 防护等级:符合 IEC 61000-4-2 标准(ESD 抗扰度)

三、产品特点

  • 高能量吸收能力:在 8/20µs 浪涌下可承受 30A 脉冲电流和 450W 峰值功率,适合直击或间接雷击及瞬态浪涌场景。
  • 低漏电、稳定钳位:1µA 的低反向电流有利于待保护电路低功耗运行,9V 的钳位电压在保护同时减小对受保护器件的应力。
  • 小型封装:SOD323 占板面积小,利于移动设备、消费电子和密集 PCB 布局。
  • 宽温度范围与工业级可靠性,适用于车规类边缘应用及恶劣环境。

四、典型应用

  • 5V 电源轨与 USB、串口等 I/O 接口的瞬态抑制
  • 工业控制模块与传感器前端保护
  • 通信设备、路由器、网关的接口防护
  • 消费类电子(摄像头、机顶盒、智能家居)防护

五、应用建议

  • 单向 TVS 的阴极连接到地,阳极接需保护的正极/信号线,确保方向正确以发挥正向钳位效果。
  • 靠近被保护器件或接口放置 TVS,短引线有助于减少寄生电感,提高抑制效率。
  • 对高频信号线(如高速数据)应用时注意选择合适封装与布局,避免引入额外串扰。
  • 对于重复或极端浪涌环境,建议并联或与其他滤波器件配合使用以延长整体可靠性。

如需器件封装图、原理接法或更详细的电气特性曲线(如钳位电压随电流变化曲线),可按需提供数据手册或参考设计。

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
