UDD32C05L01-AT 产品概述

一、产品简介

UDD32C05L01-AT 是来自 Brightking(台湾君耀)的一款车规级双向 ESD 抑制二极管,采用 SOD-323 小型封装,专为汽车电子与精密高速信号线的浪涌与静电防护设计。器件在 8/20μs 浪涌条件下可承受高达 17A 峰值脉冲电流,瞬态功率能力达 350W,适合在有限空间内实现高可靠性的瞬态过压保护。

二、主要性能与特点

  • 反向截止电压(Vrwm):5V,适配 5V 及以下工作电压的信号和电源线。
  • 钳位电压:典型钳位电压为 9.8V 与 18.3V(在标准浪涌测试条件下测得),能有效限制瞬态电压冲击。
  • 峰值脉冲电流(Ipp):17A @ 8/20μs,瞬态冲击承受能力强。
  • 峰值脉冲功率(Ppp):350W @ 8/20μs,适合短时高能量脉冲吸收。
  • 反向漏电流(Ir):典型 5μA,低漏电可减少对系统静态功耗影响。
  • 结电容(Cj):0.8pF,超低电容设计,适合高速信号线(如 USB、CAN、LVDS 等)防护,影响小。
  • 单路双向保护,便于对差分或双向信号线进行对称保护。
  • 满足 IEC 61000-4-2、IEC 61000-4-4、IEC 61000-4-5 抗扰度要求,具备车规级防护能力。

三、典型应用场景

  • 汽车车载信息娱乐系统(IVI)、AFS、车载网络接口(CAN、LIN)等外部接口防护。
  • 高速数据接口(USB2.0/3.0 较低速通道、以太网 PHY 低速线)与传感器信号线保护。
  • 点火系统开关或瞬态脉冲可能干扰的控制线。
  • 工业控制、楼宇自控等需要高可靠瞬态保护的小型模块。

四、电气参数摘要

  • 类型:ESD 抑制二极管(双向)
  • 封装:SOD-323(小型表贴)
  • 通道数:单路(1 通道)
  • Vrwm:5V
  • 钳位电压:9.8V / 18.3V(典型)
  • Ipp:17A @ 8/20μs
  • Ppp:350W @ 8/20μs
  • Ir:5μA(典型)
  • Cj:0.8pF(典型)
  • 防护等级:符合 IEC 61000-4-2 / IEC 61000-4-4 / IEC 61000-4-5

五、封装与可靠性

SOD-323 紧凑封装有利于高密度布板和自动化贴装,适配主流回流焊工艺。器件设计兼容车规环境的温度和电磁干扰要求,在符合规范的 PCB 布局与热管理下,可提供长期稳定的瞬态防护功能。

六、使用与布局建议

  • 对高速信号线应尽量靠近受保护的接口处放置,缩短受保护端与二极管之间的走线长度以获得最佳抑制效果。
  • 由于器件为瞬态能量吸收器,不可用于持续功率限流;遇到重复高能量冲击需评估可靠性与是否需要并联或外加限流元件。
  • 采用合适的回流焊温度曲线并注意防静电作业,避免在装配和测试过程中对器件施加非必要的静电应力。
  • 在双向保护应用中,器件便于直接并联于差分线与地之间或两线之间,实现对称钳位。

七、订购信息与支持

  • 品牌:Brightking(台湾君耀)
  • 型号:UDD32C05L01-AT
  • 封装:SOD-323
    如需样片、批量报价或数据手册(包含详细的钳位曲线、浪涌测试条件和典型应用电路),建议联系供应商或授权分销商获取完整资料与车规相关认证信息。

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
