UAT36A05L05 ESD二极管产品概述

一、产品简介

UAT36A05L05 是 Brightking(台湾君耀)推出的一款小型化四路ESD防护二极管,采用 SOT-363 封装,专为 5V 工作电压环境的快速信号与接口线防护设计。器件在静电放电事件中提供低电容、快速响应的钳位保护,适合对信号完整性要求高且空间受限的消费电子与工业应用。

二、主要参数与性能

  • 反向耐压(Vrwm):5V(适合 5V 系统工作电压)
  • 击穿电压:约 6V
  • 峰值脉冲电流(Ipp):3A @ 8/20µs(单次脉冲能力)
  • 钳位电压:15V(典型钳位水平,限制被保护端电压)
  • 反向漏电流(Ir):1µA(在 Vrwm 下的典型泄漏,适用于低功耗应用)
  • 结电容(Cj):约 1pF(低电容,有利于高速信号保持)
  • 通道数:四路(可同时保护多条线)
  • 封装:SOT-363(超小型,适合空间受限的终端设计)
  • 防护等级:符合 IEC 61000-4-2 静电放电防护要求

三、关键特性与优势

  • 小电容(1pF):对USB、LVDS、MIPI等高速差分/单端信号影响极小,降低信号失真与抖动。
  • 低漏电流(1µA):利于电池供电设备与低功耗系统的待机性能。
  • 四路集成:单封装内实现对多条信号线的并行保护,节省PCB空间与BOM。
  • 良好脉冲承受力:3A @ 8/20µs 的脉冲能力,可应对常见的接触型静电放电事件。
  • 小封装(SOT-363):适用于移动设备、摄像头模组、显示接口与其他空间受限场合。

四、典型应用

  • USB/USB OTG、Micro USB 接口保护(5V 系统)
  • HDMI、MIPI、相机接口等高速数据线的防护(需关注电容影响)
  • GPIO、I2C、SPI 等数字信号线的ESD防护
  • 工业控制与人机界面(HMI)端口的静电保护

五、PCB布局与使用建议

  • 器件应尽量靠近外部连接器或受保护引脚放置,走线长度越短越好以降低电感耦合。
  • 保护二极管的地端应通过宽铜皮或多过孔直接接到主地平面,形成低阻抗回流路径。
  • 对于高速差分线,注意对称布局并尽量避免在保护器件处引入不必要的串联电阻或电感。
  • 在需要进一步吸收能量的场合,可配合串联限流电阻或共模扼流圈使用以提高整体耐受能力。
  • 验证时应参考 IEC 61000-4-2 测试方法,评估接触与空气放电条件下的实际钳位与泄露行为。

六、可靠性与合规

UAT36A05L05 针对 IEC 61000-4-2 的静电放电防护进行了设计。器件具有稳定的低漏电与可预测的钳位特性,适合批量生产与长期可靠性要求较高的终端产品。在高能量反复冲击场景下,建议在系统层面做冗余防护设计并进行寿命验证。

七、封装与采购信息

  • 封装形式:SOT-363(也称 SC-70-6 小型封装)
  • 品牌:Brightking(台湾君耀)
  • 型号:UAT36A05L05
    在选型时请确认器件的方向性(单向/双向)与目标电路的工作电压匹配,并向供应商索取详细的器件规格书与封装图纸以便可靠布局与焊接工艺验证。

八、总结

UAT36A05L05 以其4路集成、小封装、低电容与对5V系统友好的电压等级,适合用于需要兼顾ESD保护与高信号完整性的移动设备与接口电路。正确的布局与系统级防护配合能够大幅提升接口抗干扰能力并降低因静电导致的功能故障风险。若需进一步的电气特性曲线、钳位测试数据或封装管脚定义,建议查阅厂商完整规格书或联系技术支持。

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
