ESD0524P 产品概述

一、产品简介

ESD0524P 是友台半导体(UMW)推出的一款四路静电与浪涌保护器件,封装为 DFN2510-10,主要用于对 5V 等低电压高速信号线的静电放电(ESD)和浪涌(Surge)保护。器件类型为 TVS/ESD,针对 IEC 61000-4-2、IEC 61000-4-4 与 IEC 61000-4-5 等电磁兼容抗扰度标准提供保护能力,适合消费电子、通信及工业控制等场景。

二、主要特性

  • 钳位电压(Vc):16V(典型峰值响应时)
  • 击穿电压(Vbr):9.5V
  • 反向截止电压(Vrwm):5V(适配 5V 信号系统)
  • 峰值脉冲功率(Ppp):80W @ 8/20μs
  • 峰值脉冲电流(Ipp):4A @ 8/20μs
  • 反向电流(Ir):100nA(典型,低泄漏)
  • 结电容(Cj):0.3pF / 0.8pF(低电容版本适合高速信号)
  • 通道数:4 路
  • 封装:DFN2510-10(紧凑型,利于靠近接口布局)

三、关键参数说明

  • Vrwm 5V 表明器件在正常工作电压下(≤5V)保持高阻,不会导通,适合保护 USB、I2C、TTL 等 5V 逻辑或接口。
  • Vbr(9.5V)为器件开始导通的击穿电压,超过该点器件进入导通以引导过压至钳位电压。
  • 钳位电压 16V 是在冲击过程中对被保护节点的最大限制值,越低越能更好保护下游电路。
  • Ppp 与 Ipp 指示器件在短时浪涌(8/20μs)条件下的能量吸收能力与电流承受能力,应避免长期或重复超过该限值。
  • 极低的结电容(0.3pF/0.8pF)有利于保持信号完整性,适用于高速数据线保护。

四、典型应用场景

  • USB 2.0/串口等 5V 信号接口防护
  • 摄像头/显示器接口(MIPI/TTL)旁路保护(需核对接口电平)
  • SIM 卡、按键矩阵及外部 I/O 接口的 ESD 保护
  • 工业与通信设备的多通道接口保护,靠近连接器或插头处布局最佳

五、封装与可靠性

DFN2510-10 紧凑封装便于在空间受限的 PCB 上靠近受保护端口放置,减小引线感抗与感应路径。器件通过 IEC 61000-4-2(静电放电)、IEC 61000-4-4(瞬态电磁脉冲)和 IEC 61000-4-5(浪涌)等试验等级验证,满足常见产品的电磁兼容性要求。

六、使用建议

  • 建议将 ESD0524P 靠近受保护的连接器或端子放置,尽量缩短走线并直接回流至接地平面。
  • 对高速信号通道选择低电容(0.3pF)版本以减小信号失真;对一般 I/O 可选 0.8pF。
  • 注意峰值功率与电流限制,避免在无热沉或不当环境下反复承受超过额定冲击。
  • 在疑问方向性(单向/双向)或并联配置时,请参照详细数据手册以确认接线与极性要求。

若需器件详细管脚说明、典型等效电路或 PCB 布局示例,请提供对接的电路类型与应用场景,我可基于具体需求给出更精确的设计建议。

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
