Leiditech PESD1LIN ESD防护器件产品概述

一、产品定位与核心价值

PESD1LIN是雷卯电子(Leiditech)针对敏感电子电路推出的小型化ESD/瞬态浪涌防护器件,核心解决“小体积下的宽温可靠性、低信号干扰与高防护能力”平衡问题,适配消费电子、汽车电子、工业控制等多领域的高速/高可靠性场景需求。其设计目标是:在不影响系统信号完整性的前提下,为电源轨、高速接口提供稳定的静电与浪涌防护。

二、核心电气参数深度解析

PESD1LIN的参数经过精准优化,覆盖不同应用场景的核心需求:

  1. 电压防护参数:反向截止电压(Vrwm)支持15V/24V,适配12V/24V系统电源轨;击穿电压(Vbr)为18.9V/27.8V,保证正常工作时无导通;钳位电压(Vc)达44V/70V,可将浪涌电压钳位在电子器件安全阈值内(如IC典型耐受电压<50V)。
  2. 信号完整性参数:结电容(Cj)仅13pF,远低于传统TVS管(通常>50pF),可兼容USB2.0(480Mbps)、HDMI1.4(10.2Gbps)等高速信号传输,避免信号衰减或失真。
  3. 低功耗与可靠性参数:反向漏电流(Ir)≤50nA(0.05μA),几乎不影响系统静态功耗;峰值脉冲功率(Ppp)160W(@8/20μs浪涌波形),可承受多次重复浪涌冲击而不失效。

三、防护性能与国际认证

PESD1LIN严格遵循国际EMC标准,防护能力覆盖:

  • 静电放电(ESD):符合IEC 61000-4-2标准,可承受接触放电±8kV、空气放电±15kV(行业典型值±4kV/±8kV);
  • 电快速瞬变脉冲群(EFT):符合IEC 61000-4-4标准,可抑制40A/μs的快速瞬变脉冲,避免后端IC误触发;
  • 浪涌冲击:160W峰值脉冲功率,可应对电源/信号线上的雷击感应、开关浪涌等瞬态干扰。

四、封装与宽温可靠性设计

  1. 小型化封装:采用SOD-323封装(尺寸1.6mm×0.8mm×0.6mm),体积仅为传统DO-15封装的1/5,适配智能手机、智能穿戴、小型化工业模块等空间受限场景;
  2. 宽温工作范围:支持-55℃~+125℃环境温度,满足汽车电子(AEC-Q100兼容)、工业现场(高低温循环)、航空航天等 harsh 环境的长期稳定运行;
  3. 长期可靠性:低漏电流设计减少自发热,配合雷卯封装工艺,125℃高温下1000小时寿命测试无性能衰减。

五、典型应用场景

PESD1LIN的参数适配性使其广泛应用于:

  1. 消费电子:智能手机/平板的USB、HDMI、音频接口防护;智能手表、蓝牙耳机的充电接口防护;
  2. 汽车电子:车载中控屏触摸接口、CAN总线、USB充电口的浪涌/ESD防护(适配汽车级温度要求);
  3. 工业控制:PLC模块数字I/O口、传感器接口的EFT/浪涌防护;
  4. 通信设备:路由器、交换机以太网接口、光纤收发器信号防护;
  5. 医疗电子:便携式医疗设备(血压计、血糖仪)电源/信号接口防护(低漏电流不影响设备精度)。

六、产品优势总结

相比同类型器件,PESD1LIN具备三大核心优势:

  • 平衡型设计:低结电容(13pF)+高防护(160W)+宽温(-55~125℃),打破“防护强则信号差”的 trade-off;
  • 小体积适配:SOD-323封装满足高密度PCB贴装需求,适配小型化产品趋势;
  • 品牌保障:雷卯电子作为国内EMC防护主流厂商,提供技术支持与定制化方案,产品经过多轮可靠性验证。

该器件通过了无铅无卤认证,符合RoHS标准,可直接用于环保要求严苛的产品设计。

BOM matching & alternatives

BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.

Electronic component sourcing availability dashboard with ESD-protected samples

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
