BEP0640SC 产品概述

一、产品简介

BEP0640SC 是 BORN(伯恩半导体)推出的一款高可靠性放电管(气体放电管/放电抑制器),采用 SMB 封装,专为中低电压线路的浪涌保护设计。该器件在正常工作条件下呈高阻抗状态,在过电压瞬变发生时迅速导通,将冲击能量引入地线或系统参考电位,从而有效保护后端敏感电子器件。产品适用于通信、电源、安防与工业控制等需要抗雷击与开关瞬变保护的场景。

二、主要性能参数

  • 断态峰值电压 (Vdrm):58 V(断态时对系统的耐压)
  • 开关电压 (Vs):77 V(触发导通所需电压)
  • 峰值脉冲电流 (Ipp):100 A(单次浪涌允许通过的峰值电流)
  • 漏电流:5 μA(断态下的微小漏电)
  • 保持电流 (Ih):120 mA(放电后维持导通所需电流)
  • 通态电压 (Vt):4 V(导通时的典型压降)
  • 通态电流 (It):2.2 A(持续通态电流能力)
  • 断态电容 (Co):80 pF(对高频信号的影响)
  • 工作温度范围:-40 ℃ 至 +150 ℃
  • 封装:SMB(表面贴装,方便自动贴装与回流焊工艺)

以上参数在实际应用中需结合系统阻抗、浪涌波形与频率特性进行评估。

三、核心特性与优势

  • 高浪涌承受能力:100 A 峰值脉冲电流使其能承受大部分直击雷或感应雷及开关瞬变引发的短时大电流冲击。
  • 低断态漏电:5 μA 的低漏电有利于对低功耗或灵敏模拟线路的保护,不会显著增加静态功耗。
  • 快速响应且低通态压降:开关电压与通态电压控制良好,导通后压降低(约 4 V),可以在保护过程中减少能量在被保护设备上的损耗。
  • 宽温度适应性:-40 ℃ 至 +150 ℃ 的工作温度满足多数工业与户外环境的可靠性需求。
  • 小封装、易于布线:SMB 封装兼顾散热与体积,适合表贴自动化生产。

四、典型应用场景

  • 通信线路保护:光纤接口旁供电线、RJ45 网络端口、基站及交换设备的直流/话务线保护。
  • 电源与供电模块:开关电源输入端、分配电源和备用电源线路的浪涌防护。
  • 工业与安防设备:PLC、传感器集线器、门禁与监控摄像头等对外引线的抗雷击防护。
  • 汽车电子(视认证与温度需求):用于车载低压电源或信号线的暂态抑制(需按车规要求验证)。

五、安装与使用建议

  • 放电管应靠近被保护端口或接地点布置,减小线路阻抗与环路面积,以优化能量引流路径。
  • 采用良好的地线连接,低阻抗的接地能显著提升防护效果并降低系统干扰。
  • 在多个放电器件并行使用或与其他浪涌保护元件(如 TVS 二极管、保险丝)组合时,应根据系统浪涌能量分配选择合适的序列与并联结构。
  • 回流焊工艺应考虑 SMB 封装的热稳定性,避免超温或长时间加热导致封装裂纹。

六、可靠性与环境注意事项

  • 工作温度范围宽,适合多数工业环境;但在高温或高湿环境中仍建议做加速寿命验证。
  • 放电事件会在器件内部产生能量耗散,多次大能量放电可能影响长期可靠性,应在系统设计中评估最大重复冲击能力并考虑配套保护(如可熔断器)。
  • 储存与运输应避免强震动、潮湿和静电环境,防止封装及引脚损伤。

七、选型与替代参考

在选型时,优先核对系统最大持续电压、触发电压与最大浪涌电流;若系统工作电压高于 58 V 或需更低触发电压/更高耐受电流,请选择相应参数更高或更适配的型号。与 TVS 二极管协同使用时,可实现更快的响应与更平滑的能量分担。

八、订购信息与标记

产品型号:BEP0640SC;品牌:BORN(伯恩半导体);封装:SMB。订购时请确认批次、出厂检测报告与规格书,以便满足特定应用的质量与合规需求。

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.
