BEP3500SB 产品概述

一、产品简介

BEP3500SB 是 BORN(伯恩半导体)推出的一款 DO-214AA/SMB 封装半导体放电管(防雷管),额定浪涌耐受能力 4 kV,针对中高能量瞬态过压保护而设计。器件兼顾低漏电、宽温度范围与较高峰值脉冲能力,适合工业电源、通信接口、配电模块及各类含有开关电路的设备做输入侧或关键节点的过压保护。

二、主要电气参数

  • 断态峰值电压(Vdrm):320 V(器件在断态时可承受的最大静态电压)
  • 漏电流:5 μA(常态下的微小泄漏,适合对静态功耗敏感的系统)
  • 开关电压(Vs):400 V(触发/开通的参考电压)
  • 保持电流(Ih):120 mA(放电后维持导通所需的电流下限)
  • 通态电压(Vt):4 V(导通时的压降)
  • 通态电流(It):2.2 A(连续导通允许电流)
  • 峰值脉冲电流(Ipp):80 A(短时冲击浪涌电流能力)
  • 工作温度范围:-40 ℃ ~ +150 ℃(适应广泛环境条件)
  • 封装:SMB(DO-214AA)

以上参数体现出 BEP3500SB 在静态和瞬态条件下的综合保护性能:低漏电、较高的触发电压及强劲的脉冲承受能力,适合在高压或容易出现大能量瞬态的场合使用。

三、应用场景

  • 工业电源与逆变器输入侧浪涌保护
  • 配电箱、开关电源的主回路及保护回路
  • 通信基站、光纤收发模块的过压防护(输入侧)
  • 充电设施、电动车充电桩的瞬态抑制与防雷保护
  • 需要在高压下抑制短时脉冲能量的场景

四、封装与安装注意

BEP3500SB 采用 SMB(DO-214AA)贴片封装,便于自动贴装与回流焊接。PCB 布局建议:

  • 放电管与被保护端尽量靠近,走线最短以减少寄生感抗与环路面积。
  • 在可能的情况下与串联熔断器或限流元件配合使用,以避免反复触发或大能量持续作用。
  • 考虑散热与环境温度:虽然器件工作温度范围宽,但在高频次冲击或高温环境下应保证足够散热空间与良好散热设计。

五、选型与使用建议

  • 对照系统工作电压选择合适的断态峰值与开关电压,确保在正常工况下不误触发,同时能在浪涌时及时导通。
  • 留意保持电流(Ih)与系统泄漏/工作电流关系,避免触发后无法恢复或误动作。
  • 峰值脉冲电流(Ipp)决定了对短时高能量浪涌的承受能力;对经常发生较大浪涌的场合,可采用并联或配合更大能量吸收器件的方案。
  • 若需更详细的脉冲波形功率数据(如 8/20 μs 能量)、重复性寿命或寄生参数,请参考厂方完整数据手册或直接咨询供应商技术支持。

六、可靠性与检测

器件支持 -40 ℃ 至 +150 ℃ 的工作温度,适配工业级应用。出厂前应进行常规的电气参数检验与浪涌耐受测试。系统级验证建议在目标应用环境中做整机冲击(浪涌/雷击)测试,以确认保护策略与器件配合是否满足可靠性要求。

七、总结

BEP3500SB 以其 4 kV 浪涌耐受能力、低漏电与宽温度特性,为中高压场合提供了一种可靠、易于安装的过压保护方案。合理匹配系统电压、注意 PCB 布局与配套保护元件,可发挥其最佳防护效果。如有特殊波形或更高能量要求,建议与厂方或技术工程师进一步确认详细参数与定制化解决方案。

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
