AZ5825-01F 产品概述

一、产品简介

AZ5825-01F 是 Leiditech(雷卯电子)推出的一款面向 5V 系统的瞬态抑制二极管(ESD 抑制器),采用小型 DFN1006 封装,专为对静电放电(ESD)和雷击/浪涌(Surge)保护有要求的接口与电源线设计。该器件在保持小封装和低结电容的同时,提供较高的峰值脉冲能量承受能力,对便携式设备、消费类电子和工业接口保护具有很好的适配性。

二、主要性能与参数

  • 反向截止电压 (Vrwm):5 V(适用于 5V 及以下工作电压保护)
  • 击穿电压 (Vbr):6 V
  • 钳位电压(典型):12.5 V
  • 峰值脉冲功率 (Ppp):80 W(按 8/20 μs 波形)
  • 反向电流 (Ir):500 nA(在 Vrwm 条件下)
  • 结电容 (Cj):15 pF(低电容,有利于多数数据信号线的信号完整性)
  • 防护等级/标准:符合 IEC 61000-4-2(ESD)与 IEC 61000-4-5(浪涌)要求
  • 类型:ESD 保护二极管
  • 品牌:Leiditech(雷卯电子)
  • 封装:DFN1006(微小、低剖面封装,便于高密度 PCB 布局)

三、特点与优势

  • 针对 5V 系统优化的 Vrwm,使其在不影响正常工作电压的情况下提供可靠保护。
  • 12.5 V 钳位电压能有效限制瞬态过压,减小后端电路承受的冲击能量。
  • 80 W@8/20 μs 的峰值脉冲功率表示可吸收较强的浪涌能量,适合接口侧抗雷击/浪涌要求较高的场合。
  • 15 pF 的结电容在多数常见数据信号(如 USB2.0、UART、I2C 等)上仍能保持较好的信号完整性。
  • DFN1006 小封装有利于移动设备和高密度板级设计,同时降低寄生电感。

四、典型应用场景

  • USB(特别是 USB2.0/USB1.x)端口及其数据线保护(适用于 5V 供电体系)
  • 手机、平板、可穿戴设备等便携式终端的接口保护
  • I/O 信号线、GPIO、UART、I2C 总线等低电压数据信号保护
  • 工业控制设备与仪表中对静电与短时浪涌防护的电路保护
  • 网络模块、蓝牙、Wi‑Fi 模块的供电/数据接口防护(需结合速率与电容要求评估)

五、设计与 PCB 布局建议

  • 将 AZ5825-01F 靠近被保护的接口或引脚放置,走线尽量短直,以减少串联电感带来的尖峰电压上升。
  • 在封装附近预留充足的地回流通道,确保浪涌电流能经低阻抗路径快速回流到地。
  • 对差分或高速信号线,评估 15 pF 的结电容对信号上升/下降时间及眼图的影响;若系统对高频性能极为敏感,应在选型时做实际测量验证。
  • 焊接与回流工艺请按照供应商推荐的回流曲线及焊盘设计规范执行,避免热应力或焊接缺陷导致可靠性问题。
  • 处理与装配过程中注意防静电(ESD)防护,器件本身用于吸收静电但也需在安全环境下操作以避免损坏。

六、合规性与包装

AZ5825-01F 对应 IEC 61000-4-2(接触/空放静电)与 IEC 61000-4-5(浪涌)相关测试项,适合用于需要满足这些电磁兼容标准的产品设计。封装为 DFN1006,适用于自动贴片生产线。具体包装形式、运输与储存建议请参照 Leiditech 提供的产品数据表与包装说明。

七、选型要点与注意事项

  • 若目标系统为 5V 或更低电压,AZ5825-01F 的 Vrwm=5V 与 Vbr=6V 组合较为合适;对于更高工作电压场合需选择更高 Vrwm 的抑制器。
  • 钳位电压为 12.5V,应评估被保护器件在该钳位电压下的耐受能力,必要时在前端增加串联阻抗或电阻限制浪涌电流。
  • 对于非常高速或差分高速接口(如 USB3.0、HDMI、PCIe 等),需注意 15pF 电容可能影响高速信号,应进行信号完整性验证或考虑更低电容的器件。
  • 查看并遵循制造商的完整数据表,包含典型波形测试条件、热阻参数和可靠性数据,作为最终设计验证依据。

AZ5825-01F 是一款适配 5V 系统的通用 ESD/浪涌保护器件,结合小型封装与适中的电气特性,适合用于对接口保护有常规抗 ESD/Surge 要求的消费类与工业电子产品。若需进一步的测试曲线或封装机械图,请联系 Leiditech 获取完整数据资料。

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.
