AOZ8904CIL 产品概述

一、产品简介

AOZ8904CIL 是一款四路单向静电放电(ESD)保护二极管阵列,采用 SOT-23-6 小型封装,面向对高速信号线和低电压供电线的瞬态浪涌与静电放电保护。器件具有低结电容(Cj≈1.25pF)、低泄漏电流(Ir≈1µA)和较低箝位电压(Vc=18V),并通过 IEC 61000-4-2(ESD)与 IEC 61000-4-5(浪涌)等工业防护标准认证,适合消费类与工业类接口保护。

二、主要性能特点

  • 钳位电压:18V(在指定脉冲条件下)
  • 反向工作电压(Vrwm):5.5V,适用于5V/USB等系统保护
  • 击穿电压:6.6V
  • 峰值脉冲功率(Ppp):50W
  • 峰值脉冲电流(Ipp):4A @ 8/20µs
  • 结电容:典型值 1.25pF,适合高速数据线
  • 反向电流:1µA(低漏电)
  • 通道数:4 路单向保护
  • 工作结温范围:-40℃ ~ +125℃
  • 封装:SOT-23-6,6 引脚紧凑封装

三、典型应用场景

  • USB、USB-C(配合线路选择)、HDMI、DisplayPort 等高速数据接口的ESD保护
  • 手机、平板、消费电子外部接口保护
  • 工业控制器与通信模块的接口防护
  • 节点端口、信号线对地浪涌与静电事件的本地抑制

四、设计与布局建议

  • 器件应尽量靠近被保护的连接器或输入端放置,以减少印制板走线感抗和延迟护放电路径。
  • 对于频繁承受高能量浪涌的场合,可在保护器与线路间并联小阻值或阻容滤波器以分摊能量。
  • 单向结构建议用于对地参照明确的接口(如Vbus、信号对地),若用于差分对需注意参考地和布局的一致性。
  • 在多通道封装中,共用地引脚的回流路径应宽且短,以降低接地阻抗并提升保护性能。

五、结语

AOZ8904CIL 以其低电容、低漏电、高抗脉冲能力以及紧凑的 SOT-23-6 封装,适合各种对信号完整性与抗扰性要求较高的系统。选型时请结合具体系统电压、最大容许箝位以及实际浪涌能量评估,必要时参考厂方数据手册进行详细脉冲测试与布板验证。

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
