1.5KE47CA/B 产品概述

1.5KE47CA/B 为 Brightking(台湾君耀)生产的一款单向瞬态电压抑制二极管(TVS),采用 DO-201 封装,专为抑制瞬态过电压和浪涌冲击设计。该器件在工业电源、通信接口及各类电子设备的输入端与电源线上提供可靠的瞬态保护,能够在极短时间内吸收能量并将电压钳位在安全范围内,防止后端电路因浪涌或静电放电而受损。

一、主要参数概览

  • 极性:单向
  • 反向截止电压(Vrwm):40.2 V
  • 击穿电压(Vbr):44.7 V
  • 钳位电压(Vc):64.8 V(在指定脉冲条件下测得)
  • 峰值脉冲电流(Ipp):23.5 A
  • 峰值脉冲功率(Ppp):1.5 kW(测试波形 10/1000 μs)
  • 反向电流(Ir):1 μA(典型值,在规定测试条件下)
  • 类型:TVS(瞬态电压抑制器)
  • 品牌:Brightking(台湾君耀)
  • 封装:DO-201(轴向引线、便于波峰焊或手工焊接)

二、主要特性

  • 强大的浪涌吸收能力:在标准 10/1000 μs 测试波形下可承受 1.5 kW 的峰值功率,对短持续时间的大能量脉冲具有良好缓解效果。
  • 清晰的钳位保护:在指定浪涌条件下可将峰值电压钳位于约 64.8 V,显著降低后端元器件所承受的最大电压应力。
  • 低漏电与稳定击穿:反向漏电小(Ir ≈ 1 μA),击穿电压集中(Vbr ≈ 44.7 V),便于在设计时控制静态功率损耗与阈值余量。
  • 单向配置:适用于需要单向电压抑制的场合,便于在有极性要求的电源或信号线中部署。

三、典型应用场景

  • 工业电源输入端的瞬态浪涌保护,保护开关电源、驱动模块等敏感电路。
  • 通信设备与接口防护,如调制解调器、以太网端口、串行总线输入等,抵御外来浪涌或静电干扰。
  • 电池管理、逆变器与直流配电系统的输入保护,防止瞬态电压对后端电子件造成不可逆损伤。
  • 其他对高能瞬态有抑制需求的消费电子与测试设备。

四、封装与安装注意

  • DO-201 轴向封装便于通过波峰焊或手工焊接,但要注意焊接温度与时长,避免超出元件的热应力承受范围(参考厂方焊接规范)。
  • 单向 TVS 有极性要求,安装时应确保正确方向:通常阴极(带标记端)接向被保护电路的供电负极或接地侧,具体以图纸或封装标识为准。
  • 为获得最佳保护效果,建议器件尽量靠近受保护端口或输入端安装,以缩短走线与寄生电感。

五、选型与使用建议

  • 若系统工作电压接近或略高于 Vrwm(40.2 V),需评估常态下漏电与功耗;若工作电压较高,考虑选择更高 Vrwm 的型号。
  • 钳位电压 64.8 V 意味着在浪涌事件中被保护电路会承受该电压峰值,选型时应确保后端元器件耐压裕量充足。
  • 对于连续或重复高能脉冲应用,应关注器件的热耗散与平均功率能力,必要时采用并联、外部限流或更高规格的浪涌保护器件。
  • 在有严格 EMI/ESD 要求的设计中,可与滤波、电阻限流或保险元件联合使用以提升整体抗扰性能与可靠性。

通过合理选型与正确布板、焊接方式,1.5KE47CA/B 能为中高能瞬态工况提供稳健且成本效益良好的过压保护,是许多需要瞬态抑制的系统中的常用选择。如需更详细的电气特性曲线、温度依赖性或焊接规范,请参考 Brightking 官方数据手册或联系供应商获取完整技术资料。

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
