ESDBL24VA1 产品概述

ESDBL24VA1 是 GOODWORK(固得沃克)推出的一款双向瞬态电压抑制器(TVS),专为保护电子设备免受静电放电(ESD)和浪涌过电压的损害而设计。器件采用极小型 DFN1006-2L 封装,具备极低结电容和微小反向漏流,适用于对信号完整性和空间有限制的消费类电子、通讯接口和工业控制端口保护。

一、主要电气参数(关键参数概述)

  • 极性:双向(bidirectional),可用于双向瞬态抑制场景,如差分信号或交流接口。
  • 反向截止电压 Vrwm:24 V(工作反向电压上限)。
  • 击穿电压 VBR:28.3 V(典型值,在规定电流条件下测得)。
  • 钳位电压(示例值):51 V;38 V(在不同标准测试电流或波形下测得的典型钳位电压,具体测试条件请参照产品数据手册)。
  • 峰值脉冲功率 Ppp:250 W(浪涌脉冲 8/20 μs 波形标准)。
  • 反向电流 Ir:100 nA(在 Vrwm 条件下的低漏电流,有利于低功耗应用)。
  • 结电容 Cj:13.7 pF(低电容设计,适合高速信号线的保护)。
  • 工作温度范围:-55 ℃ 到 +125 ℃。
  • 防护等级:符合 IEC 61000-4-2(静电放电抗扰度)标准。
  • 封装:DFN1006-2L(超小型贴片封装,便于高密度 PCB 布局)。

二、产品特点与优势

  • 低结电容(13.7 pF):对高速数据线(如 USB、PCIe 较低速部分、串行通信等)影响小,能最大限度降低对信号完整性的干扰。
  • 低漏电流(100 nA):适合对静态电流敏感的便携式与电池供电设备。
  • 高浪涌能量吸收能力(250 W @ 8/20 μs):可有效吸收工业环境和现场操作中常见的瞬态浪涌能量。
  • 双向结构:无需区分极性,便于在差分线或双向接口中直接使用。
  • 宽温度范围和可靠性:适应工业级应用环境,长期稳定性好。
  • 小型 DFN1006-2L:节省 PCB 空间,适合紧凑型模块和表面贴装自动化生产。

三、典型应用场景

  • 接口端口保护:USB、HDMI、耳机插口、串口(RS-485/RS-232)等外部接口的 ESD 与浪涌防护。
  • 通信设备:基站设备、网络交换机和路由器中对信号线和控制线的浪涌保护。
  • 消费电子:智能手机配件、平板、可穿戴设备和其它便携式终端的外部暴露端口保护。
  • 工业控制:现场总线、传感器接口和人机界面(HMI)中对静电和浪涌的防护需求。
  • 汽车电子(非直接暴露于高能环境时):作为辅助保护器件用于车载信息娱乐系统和传感器模块(需根据汽车级规范进一步确认)。

四、应用建议与 PCB 布局要点

  • 靠近受保护端口布置:将 ESDBL24VA1 尽量靠近连接器或引入点放置,缩短信号或电源到器件的走线长度,以提高防护效率。
  • 保持短而宽的接地回流路径:保证瞬态电流有低阻抗回路,减小地环路面积,提升钳位和能量吸收效果。
  • 在高频应用中注意匹配:尽管结电容低,但在极高速链路中仍需评估器件对信号的影响,可配合串联阻抗或阻尼网络优化信号完整性。
  • 热和焊接工艺:遵循常规 SMT 回流焊工艺要求,焊盘设计应与封装规范相匹配,避免机械应力集中。

五、可靠性与合规

ESDBL24VA1 设计满足 IEC 61000-4-2 静电放电抗扰度要求,器件的高温低温工作范围(-55 ℃ 至 +125 ℃)确保可在苛刻环境下长期稳定工作。低漏电和耐浪涌能力提升了在实际应用中的可靠性表现。详细的认证测试条件与结果请参照 GOODWORK 官方数据手册。

六、选型与注意事项

  • 确认钳位与系统耐受性:在选择 TVS 时,应根据系统能够承受的最大瞬态电压确定钳位电压是否满足要求。数据中给出的 51V 和 38V 为不同测试条件下的钳位参考值,具体应用请结合实际浪涌电流与器件数据页曲线进行评估。
  • 双向配置适用场景:若保护单向电源线或对地参考明确的场合,考虑使用单向 TVS;ESDBL24VA1 更适合差分或双向突发过压场景。
  • 请参考生产商数据手册以获得完整的电气特性曲线、封装外形和推荐 PCB 焊盘尺寸。

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
