5.0SMDJ58CA 产品概述

5.0SMDJ58CA 为 DOWO(东沃)出品的一款高能量瞬态抑制二极管(TVS),采用 SMC(DO-214AB)封装,属于双向保护器件。该器件专为吸收和钳位大能量瞬态浪涌而设计,适用于工业电源、通信接口、直流母线及其它需要高能保护的电路中。

一、主要参数一览

  • 型号:5.0SMDJ58CA
  • 类型:双向 TVS(瞬态电压抑制二极管)
  • 封装:SMC (DO-214AB)
  • 反向截止电压 Vrwm:58 V
  • 击穿电压 Vbr:64.4 V
  • 钳位电压 Vc(Ipp):93.6 V
  • 峰值脉冲电流 Ipp(10/1000 μs):53.42 A
  • 峰值脉冲功率 Ppp(10/1000 μs):5 kW
  • 反向静态电流 Ir:5 μA(在 Vrwm 条件下)
  • 工作温度范围:-55 ℃ ~ +150 ℃
  • 极性:双向

二、功能与特点

  • 高能量吸收:Ppp 高达 5 kW(10/1000 μs),能有效吸收交流或脉冲式浪涌能量。
  • 双向保护:能同时抑制正、负极性瞬态,适合交流电源或双极信号线的保护。
  • 低漏电流:典型 Ir 为 5 μA,在静态工作下对电路影响小。
  • 宽温工作:-55 ℃ 到 +150 ℃ 的工作温度范围,适用于恶劣环境和工业级应用。
  • SMC 封装:体积适中、热性能好,便于表面贴装自动化生产。

三、典型应用场景

  • 工业控制电源和配电系统的浪涌保护(SPD)
  • 电机驱动、变频器的输入输出端抑制浪涌
  • 通信基站、电源模块及配电箱的过压保护
  • 直流母线、蓄电池管理系统(BMS)及太阳能逆变器的瞬变抑制
  • 对称/双向脉冲或交流线缆的保护场合

四、选型与使用建议

  • 根据工作电压选择 Vrwm:本器件 Vrwm 为 58 V,适用于额定线电压接近或高于该值的系统;若系统常态电压远低于 Vrwm,可选择更低 Vrwm 的型号以获得更优保护。
  • 钳位能力匹配负载耐压:在 Ipp(53.42 A)条件下钳位电压约 93.6 V,应确保被保护设备在此钳位电压下不会发生损坏。
  • PCB 散热与焊盘设计:峰值能量吸收时产生较大热量,推荐使用较厚的铜箔、增加散热铜区域及过孔进行热量传导到背面散热层。
  • 自动化回流焊兼容:SMC 封装适合回流焊流程,但建议遵循厂家推荐的回流曲线,避免长时间高温导致器件退化。
  • 双向 vs 单向:交流或有正负极交换的线路优先选用双向型号;对单极性直流电源,可考虑单向 TVS 以获得更低钳位电压。

五、可靠性与测试

该器件标称在 10/1000 μs 浪涌波形下可承受 5 kW 峰值功率。实际设计中建议进行整机或子系统级的浪涌试验验证(如 10/700 μs、IEC 或厂商指定波形),并预留一定裕量(derating)以提升长期可靠性。

六、封装与安装要点

  • SMC(DO-214AB)体积较大,焊盘需按封装规范设计,保证良好接触和热传导。
  • 焊接后建议避免器件正对大功率器件近距热源,利于散热与寿命。
  • 存储、回流及波峰焊等工艺过程中遵照东沃提供的数据手册中的温度与湿敏等级说明。

总结:5.0SMDJ58CA 是一款面向高能量瞬态抑制的双向 TVS 器件,具有 5 kW 的强大浪涌吸收能力、较低的漏电流与宽温度范围,适用于各种工业、电力与通信设备的浪涌保护。在使用时应注意与系统工作电压、设备耐压和 PCB 散热设计相匹配,以确保长期稳定可靠的防护效果。若需更详细的电气特性曲线、封装尺寸或典型应用电路,建议参考东沃的完整数据手册或联系供应商获取技术支持。

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
