ESDBL15VA1 产品概述

一、产品简介

ESDBL15VA1 是 CJ(江苏长电/长晶)推出的一款单路双向瞬态浪涌抑制(ESD)二极管,专为各种高速数据接口与敏感信号线提供线路级静电放电保护而设计。该器件在小型 DFNWB1.0x0.6-2L 封装内实现低电容、高能量吸收能力与低泄漏电流的平衡,适用于空间受限且对信号完整性有要求的应用场景。

二、主要参数

  • 极性:双向
  • 反向截止电压 (Vrwm):15 V
  • 钳位电压:40 V(在指定脉冲条件下)
  • 峰值脉冲电流 (Ipp):4 A @ 8/20 µs
  • 峰值脉冲功率 (Ppp):160 W @ 8/20 µs
  • 击穿电压:23 V
  • 反向电流 (Ir):1 µA(典型/最大值)
  • 通道数:单路
  • 防护等级:符合 IEC 61000-4-2 标准
  • 结电容 (Cj):约 15 pF
  • 类型:ESD 抑制器件
  • 封装:DFNWB1.0×0.6-2L
  • 品牌:CJ(江苏长电/长晶)

三、性能特点

  1. 高效能量吸收:在 8/20 µs 波形下可承受 4 A 峰值脉冲电流和 160 W 峰值功率,能够有效吸收来自静电放电或瞬态浪涌的能量,保护后端电路免受损害。
  2. 低钳位电压:典型钳位电压约 40 V,可在突发冲击时限制线路电压,减小对敏感器件的冲击。
  3. 低结电容:约 15 pF 的结电容使其对高速信号的影响较小,适合用于 USB、串口、视频和其他高速数据线的防护。
  4. 低泄漏电流:反向电流 ~1 µA,适配对功耗敏感或高阻输入的应用。
  5. 双向保护:双向结构可同时应对正负极性的静电冲击,简化双向信号线的保护设计。
  6. 小尺寸封装:DFNWB1.0×0.6-2L 小封装有利于在 PCB 上节省空间并便于贴装自动化生产。

四、典型应用场景

  • USB、HDMI、DP 等高速接口的保护
  • 手机、平板、笔记本等便携设备的外部接口防护
  • 工业控制、通信设备、消费电子中敏感信号线的浪涌与静电防护
  • 摄像头模组、传感器接口、电源管理外围保护

五、封装与可靠性

DFNWB1.0×0.6-2L 封装尺寸小,适合表面贴装(SMT)工艺,便于自动化生产与大批量制造。器件经过 IEC 61000-4-2 等级的测试验证,具备良好的静电耐受能力。推荐在实际应用中参考厂商的焊接工艺建议与回流曲线,以保证焊接可靠性和长期使用稳定性。

六、使用建议与注意事项

  • 建议将 ESDBL15VA1 靠近被保护的连接器或引脚放置,以缩短回路长度,提升防护效果。
  • 在需要更好信号完整性的场合,可与小阻值串联元件或差分滤波器配合使用,平衡保护和带宽需求。
  • 注意不要在连续高电压或超出 Vrwm 的条件下长期工作,以免器件进入击穿或损坏。
  • 对于高能量重复性脉冲的场合,需评估热耗散与器件寿命,必要时采用并联或外加能量吸收器件进行分担。

ESDBL15VA1 在体积小、性能均衡的前提下,为各类电子终端提供可靠的线路级静电保护,是空间受限且对信号完整性有要求的系统的理想选择。若需更详细的电气特性曲线、封装尺寸图或 PCB 布局建议,可参考 CJ 官方规格书或联系供应商获取支持。

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
