HESDNC5VB1CL-A 双向ESD防护器件产品概述

HESDNC5VB1CL-A是华轩阳电子(HXY MOSFET)推出的单路双向ESD防护器件,专为敏感电子电路的静电放电(ESD)和电快速瞬变脉冲群(EFT)干扰防护设计,兼具低结电容、高瞬态耐受能力与宽温适应性,可满足消费电子、汽车电子、工业控制等多领域的防护需求。

一、产品定位与核心价值

本器件定位于高速信号链路的瞬态干扰防护,核心价值在于平衡「低电容信号完整性」与「高能量脉冲防护」——既不会因电容过高影响USB、HDMI等高速接口的信号传输,又能有效泄放静电或EFT带来的强瞬态能量,避免后端IC因过压损坏。其双向防护特性无需区分电路极性,进一步简化了PCB布局设计,降低了电路设计复杂度。

二、关键参数深度解析

1. 防护阈值与导通特性

  • 反向截止电压(Vrwm)5V:正常工作时漏电流仅1uA,不干扰电路静态功耗,适配3.3V/5V等常见电源系统;
  • 击穿电压7.8V:瞬态电压超过该值时,器件快速从截止态转为导通态;
  • 钳位电压18.6V:远低于多数敏感IC的耐压上限(如3.3V系统典型耐压20V),有效抑制过压冲击。

2. 瞬态耐受能力

  • 峰值脉冲电流(Ipp)9A(8/20μs波形)、峰值脉冲功率(Ppp)90W:可承受IEC 61000-4-2标准下的强ESD脉冲(接触放电8kV、空气放电15kV),以及IEC 61000-4-4标准下的EFT干扰(4kV/5kHz),覆盖日常使用中常见的静电冲击与电磁干扰。

3. 信号兼容性

  • 结电容(Cj)15pF:属于低电容ESD器件范畴,对100Mbps以上的高速数字信号(如USB 2.0、HDMI 1.4)的传输延迟、串扰影响极小,适配高速接口的信号完整性要求。

4. 环境适应性

  • 工作温度范围-40℃~+125℃:满足工业级与汽车级的宽温需求,可在户外、高温车间等严苛环境下稳定工作。

三、防护性能优势

1. 双标准兼容

同时符合IEC 61000-4-2(ESD)与IEC 61000-4-4(EFT)国际防护标准,覆盖电子设备常见的瞬态干扰场景,无需额外设计多重防护,降低系统成本。

2. 快速响应

击穿电压稳定,触发时间处于ns级(典型值<1ns),能在静电脉冲到达后端IC前快速导通泄放能量,将过压冲击降至最低,避免器件损坏。

3. 小体积高集成

采用SOD-523超小型表面贴装封装,尺寸仅约0.8mm×0.6mm×0.4mm,节省PCB空间,适配智能手机、智能穿戴等便携式设备的高密度布局。

四、典型应用场景

  1. 消费电子:智能手机、平板电脑、笔记本电脑的USB Type-C、HDMI、音频接口ESD防护;智能手表、耳机等穿戴设备的充电/传感器接口防护;
  2. 汽车电子:车载信息娱乐系统(IVI)的USB、蓝牙接口防护;汽车摄像头、胎压监测传感器的信号接口瞬态干扰防护(符合汽车级宽温要求);
  3. 工业控制:PLC可编程逻辑控制器的I/O接口防护;工业传感器、RS485通信模块的ESD/EFT防护;
  4. 通信设备:路由器、交换机的以太网接口、光纤收发器接口的高速信号防护。

五、品牌与品质保障

华轩阳电子专注功率器件与防护器件研发生产近10年,HESDNC5VB1CL-A通过了严格的可靠性测试(温度循环、湿度老化、ESD重复冲击等),批量生产参数一致性好(离散性控制在±5%以内),符合RoHS环保指令要求,可放心用于各类电子产品设计。

本器件以「高性能、小体积、宽适配」为核心特点,是敏感电子电路瞬态干扰防护的高性价比选择。

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
