BEP0080SC 产品概述

一、概述

BEP0080SC 是 BORN(伯恩半导体)推出的一款半导体放电管(Thyristor Surge Suppressor, TSS),采用 SMB 表面贴装封装,面向需要浪涌/瞬态过压保护的电子线路。该器件在常态下呈高阻抗,当线路出现超过触发电压的瞬态冲击时快速导通,将冲击能量钳位到安全电压并通过回路分流,从而保护后端敏感电路不被损坏。器件工作温度范围宽(-40℃~+150℃),适用于多种工业与消费类应用。

二、主要参数(关键指标)

  • 断态峰值电压 Vdrm:6 V
  • 触发/开关电压 Vs:25 V
  • 峰值脉冲电流 Ipp:100 A
  • 通态电压 Vt:4 V(It=2.2 A)
  • 通态电流 It:2.2 A
  • 保持电流 Ih:30 mA
  • 漏电流:5 μA(断态)
  • 断态电容 Co:80 pF
  • 工作温度:-40℃ ~ +150℃
  • 封装:SMB(表面贴装)

三、工作原理简述

该 TSS 在正常电压下维持高阻抗,漏电流极小(5 μA),不会对正常电路造成影响。当受到瞬态过压并超过其触发电压(Vs ≈ 25 V)时,器件迅速触发导通,将线路电压钳位至通态电压 Vt(典型 4 V),并承受冲击峰值电流(可达 100 A),在冲击结束且回路电流降至保持电流 Ih(30 mA)以下后恢复到高阻态。

四、主要特性与优势

  • 响应速度快,适合钳位短时高能脉冲。
  • 宽温度范围,能在较高环境温度下工作。
  • 漏电流低,对休眠和低功耗系统影响小。
  • SMB 封装适合自动化贴装与批量生产,热性能与机械强度兼顾。

五、应用场景与注意事项

  • 典型应用:电源总线防护、通信线路防雷/浪涌保护、工业接口保护、消费电子过压防护等。
  • 注意器件为钳位/自保持型:在设计保护回路时需考虑该器件在导通后会在电流低于 Ih 前保持导通,需与限流器件(保险丝、限流电阻或电流源断路装置)配合使用,以避免长时间导通导致器件损坏或系统故障。
  • 对高速数据线(高带宽信号)应用需注意断态电容 Co(80 pF)可能影响信号完整性,必要时选择更低电容的保护器件或采用差分/隔离方案。
  • 虽然工作温度上限为 150℃,在实际 PCB 设计中仍应为器件提供良好散热路径并遵循厂家回流焊工艺建议。

六、封装与可靠性建议

SMB 封装便于 SMT 贴装,推荐根据生产工艺采用标准回流焊曲线。量产前应做浪涌能量循环测试与热冲击测试,验证在系统最大冲击能量下的重复承受能力。对关键应用建议参考厂商完整器件数据手册与可靠性报告。

七、选型与采购建议

在选型时请结合系统峰值冲击电流、触发电压需求与信号带宽要求,确认 Vdrm、Vs 与 Ipp 等参数满足应用场景;并与供应商确认封装引脚标识、外形尺寸与认证信息。若需双向保护、低电容或更高能量承受能力,可与厂家沟通对应型号或定制方案。

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
