PESD1LIN-ES 产品概述

一、产品简介

PESD1LIN-ES 是 ElecSuper(静芯微)推出的一款单路双向瞬态抑制器(ESD Protector),采用 SOD323 小体积封装,面向需要高可靠静电防护的接口保护场景。器件在保证低反向漏电的同时,具备快速钳位响应与较高脉冲承受能力,适用于消费电子、通信接口及工业控制端口等敏感信号线保护。

二、主要参数一览

  • 极性:双向
  • 反向工作电压 Vrwm:15V、24V(两种规格可选)
  • 击穿电压 Vbr:16.5V(对应15V类)、26V(对应24V类)
  • 钳位电压 Vclamp:典型 45V
  • 峰值脉冲电流 Ipp(8/20µs):13A
  • 峰值脉冲功率 Ppp(8/20µs):450W
  • 反向电流 Ir:≤1µA(在 Vrwm 下)
  • 结电容 Cj:28pF
  • 通道数:单路(单线保护)
  • 工作温度范围:-40℃ 至 +125℃
  • 防护等级:符合 IEC 61000-4-2(静电放电抗扰度)
  • 封装:SOD323

三、电气性能说明

  • 双向结构允许器件在正负极性静电脉冲中工作,无需外加极性识别电路,适合数据线及信号线的双向浪涌场景。
  • 较低的反向漏电(1µA)保证了在高阻电路或电池供电设备中不会产生明显的静态功耗。
  • 28pF 的结电容对高速信号有一定影响,应在对信号带宽敏感的应用中评估其可接受性;对USB、UART类中低速数据线通常影响有限。

四、封装与可靠性

SOD323 封装体积小、焊接可靠,适合贴片工艺与高密度PCB布局。器件额定工作温度覆盖工业级范围(-40℃~+125℃),在常见温度应力下具有稳定的防护性能。

五、典型应用场景

  • 手机、平板、可穿戴设备的外部接口保护(耳机、按键、充电口)
  • 串行通信(UART/RS-232)、I²C、SPI 的信号线防护
  • 工业控制面板与传感器接口的静电防护
  • 车载信息娱乐与辅助电子系统中对单根信号线的浪涌防护(需按车辆规范评估)

六、选型与使用建议

  • 根据系统工作电压选择 Vrwm(15V 或 24V),保证常态电压低于 Vrwm,从而避免误触发。
  • 若应用对信号完整性高度敏感,注意 28pF 结电容可能引入的失真或带宽限制,必要时采用低电容型号或外加滤波方案。
  • 布局上建议将器件置于接口靠近外壳处,靠近受保护引脚并尽可能缩短到接地平面的返回路径。避免通过长走线连接以减少感应尖峰。

七、典型接法与布局要点

  • 单线保护:将 PESD1LIN-ES 一端接被保护线,另一端接地(共模/参考地),在双向器件中保持对称连接。
  • 地线应使用宽短回流路径,避免长串联走线或通过小孔连接,必要时配合地平面与旁路电容以提升吸收能量能力。
  • 对于多通道接口,器件应并排靠近各引脚安装,避免把保护器件集中放置在远离接口的位置。

如需器件的时序波形、钳位曲线或封装尺寸图(PCB footprint),可提供进一步资料以便针对具体电路进行详细评估与布局优化。

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
