UBT23A05L02 ESD二极管 产品概述

一、产品简介

UBT23A05L02 是 Brightking(台湾君耀)推出的一款双路低容抗静电二极管,封装为 SOT-23。针对快速数据线与电源线的静电放电(ESD)保护设计,适用于 5V 系统与高速接口,能在瞬态脉冲发生时迅速限幅,保护下游敏感器件。

二、主要参数

  • 反向截止电压 Vrwm:5V(适合 5V 系统)
  • 击穿电压 Vbr:6V
  • 钳位电压(典型):15V(在 8/20µs 测试波形下)
  • 峰值脉冲电流 Ipp:3A @ 8/20µs
  • 反向电流 Ir:500nA(常温)
  • 通道数:双路(两线并入单芯片保护)
  • 结电容 Cj:0.4pF / 0.8pF(低电容设计,适合高速信号)
  • 防护等级:满足 IEC 61000-4-2 标准(接触/氣隙放电防护)

三、封装与外形

SOT-23 小体积封装,适合空间受限的移动设备、USB/HDMI 接口板、摄像头模块等。封装提供良好的热与电气连接,同时便于贴片加工。

四、主要特性与优势

  • 低钳位电压:在高能脉冲时有效限幅,降低对后级芯片的冲击。
  • 低结电容:0.4pF/0.8pF 有利于保持高速信号完整性,适用差分或单端高速线路。
  • 低泄漏电流:500nA 降低系统静态功耗与误触发风险。
  • 双路集成:节省 PCB 面积,降低 BOM 成本与装配复杂度。
  • 符合 IEC 61000-4-2:适合抗静电要求严格的产品设计。

五、典型应用场景

  • 智能手机、平板与便携式设备的 I/O 保护
  • USB、HDMI、MIPI、CSI 等高速信号线防护
  • 摄像头模块、显示器驱动、工业控制接口
  • 通信终端与消费电子产品的静电防护点

六、典型电路与布局建议

将 UBT23A05L02 靠近外部连接器或信号入口放置,缩短受保护线到二极管的走线;器件地端应直接回到系统地并使用短而粗的过孔/回流路径,避免将敏感信号线穿过二极管下方或地平面切割。对高频差分线,优先选择低容差通道以维持信号完整性。

七、可靠性与合规性

器件经过 ESD 测试并满足 IEC 61000-4-2 要求;SOT-23 封装适合常规 SMT 工艺,推荐在生产过程中遵循湿敏等级与回流焊温控规范以保证长期可靠性。

八、注意事项与选型建议

  • 对 5V 系统尤为适配,若系统工作电压更高需选用对应 Vrwm 更高的器件。
  • 对于极高速差分信号,优先参考结电容较低的通道或选型更低 Cj 的产品系列。
  • 在高温或严苛环境下需评估泄漏电流与钳位性能可能的偏移。

九、采购与包装信息

品牌:Brightking(台湾君耀);封装:SOT-23;型号:UBT23A05L02。常见为卷装供货,适合自动贴片生产。如需样片、样品测试或大批量采购,可联系供应商获取完整规格书(Datasheet)与应用说明。

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
