PESDALC10N5VU 产品概述

一、产品简介

PESDALC10N5VU 是台舟电子(TECH PUBLIC)推出的一款四路单向 TVS 晶体管阵列,专为5V工作系统的瞬态过压、浪涌和静电放电保护设计。器件封装为 DFN2510-10,体积小、引脚配置适合贴片安装,适用于对高速信号干扰敏感且空间受限的应用场景。

二、主要参数

  • 极性:单向(unidirectional)
  • 反向稳态电压 Vrwm:5 V
  • 击穿电压 Vbr:9.5 V(典型)
  • 钳位电压(典型):16 V
  • 峰值脉冲电流 Ipp:4 A @ 8/20 µs
  • 峰值脉冲功率 Ppp:80 W @ 8/20 µs
  • 反向泄漏电流 Ir:100 nA(典型)
  • 通道数:4 路
  • 结电容 Cj:0.8 pF;0.3 pF(取决于测试条件/端口)
  • 工作温度:-55 ℃ ~ +125 ℃
  • 防护等级:符合 IEC 61000-4-2(ESD)、IEC 61000-4-4(EFT)、IEC 61000-4-5(浪涌)
  • 封装:DFN2510-10(小型 SMT)

三、关键性能与优势

  • 低结电容:典型 0.3–0.8 pF,保证对高速信号(如 USB、CMOS 接口等)的最小加载与失真。
  • 高能量吸收能力:80 W(8/20 µs)峰值功率与 4 A 峰值脉冲电流,能够有效吸收工业级浪涌与开关瞬态。
  • 低泄漏电流:100 nA 级别,适合对静态功耗敏感的系统。
  • 宽工作温度范围与工业级可靠性,适应严苛环境下长期工作。
  • 多路集成设计减少外形尺寸与 BOM 成本,适合接口防护和板级保护。

四、典型应用场景

  • USB、串行接口、I2C/SPI 等 5 V 及高速数据线路的 ESD 与浪涌防护。
  • 工业控制、PLC、仪器仪表的接口保护。
  • 通信设备、消费电子的端口防护与瞬态抑制。
  • 汽车电子(非高可靠车规等级)和楼宇自动化中对 ESD/EFT/Surge 的局部保护。

五、使用建议与封装信息

  • 布局原则:TVS 尽量靠近被保护的连接器或接口放置,保护引脚到接地端的走线应尽量短且粗,以减少环路电感并保证钳位效果。共地布线时建议使用固体地平面并在器件附近增加过孔以改善散热。
  • 封装:DFN2510-10 紧凑且便于自动化贴装,焊盘设计请参考厂商封装说明书以保证焊接可靠性。
  • 回流焊:建议采用标准无铅回流曲线进行 SMT 焊接,避免长时间暴露于高温以保护器件性能。
  • 测试注意:结电容与钳位电压受测试电压及频率影响,实际设计中建议按系统条件进行验证。

六、可靠性与标准认证

PESDALC10N5VU 对常见的工业和消费级抗扰度标准(IEC 61000-4-2/4-4/4-5)具备保护能力,能满足大多数现场安装的 ESD、EFT 与浪涌防护要求。器件的工作温度覆盖工业级 -55 ℃ 到 +125 ℃,适合拓展到温度环境复杂的应用。

七、总结

PESDALC10N5VU 提供四路、单向、低电容的紧凑型 TVS 保护解决方案,兼顾高速信号完整性与强力瞬态吸收能力。对于需要在有限空间内实现多路口保护、同时对 ESD/EFT/Surge 有高要求的系统(如消费电子接口、工业通讯端口等),该器件是一个性价比较高且易于集成的选择。建议在最终设计中结合实际信号速率与浪涌能量做电路仿真与板级验证。

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
