5.0SMDJ24CA 产品概述

一、产品简介

5.0SMDJ24CA 为 DOWO(东沃)出品的一款单路瞬态电压抑制二极管(TVS),封装为 SMC(DO-214AB),专为 24V 等中高压直流系统提供瞬态过压保护设计。器件可在极短时间内吸收大能量脉冲,保护下游电子元件免受浪涌、雷击及换向过电压影响,适用于工业、电源、汽车电子及通讯设备等场景。

二、主要参数

  • 反向截止电压 (Vrwm):24 V
  • 击穿电压 (Vbr):26.7 V
  • 钳位电压 (Vc):38.9 V(于规定测试条件下)
  • 峰值脉冲电流 (Ipp):128.5 A
  • 峰值脉冲功率 (Ppp):5 kW
  • 通道数:单路(单向或双向型号需参照型号后缀)
  • 工作温度范围:-55 ℃ ~ +150 ℃
  • 类型:瞬态抑制二极管(TVS)
  • 封装:SMC (DO-214AB)

(注:上述钳位电压与脉冲数据基于标准测试波形与条件,详细特性请参阅完整数据手册。)

三、核心特性

  • 高能量吸收能力:Ppp = 5 kW,配合短时大电流吸收能力,能在瞬时冲击下有效钳位电压,保护负载。
  • 低钳位电压:在规定冲击下 Vc ≈ 38.9 V,降低对被保护器件的应力。
  • 宽温区稳定工作:支持 -55℃ 至 +150℃,满足严苛环境与长期可靠性需求。
  • SMC 封装:适合表面贴装工艺,便于自动化装配,且具备良好热散能力。

四、典型应用场景

  • 24V 工业电源和控制系统的输入/输出保护。
  • 汽车电子(车载总线、车身电子模块)中的浪涌保护(需确认车规级要求)。
  • 通信设备、电源模块、逆变器与电机驱动的瞬态抑制。
  • 终端设备接口(如电源接口、传感器接口)防雷击与浪涌保护。

五、封装与热管理

SMC(DO-214AB)封装提供良好的功率耗散路径,建议在 PCB 设计时:

  • 使用较宽的元件焊盘和多层接地/电源平面以提高散热能力;
  • 在高能量冲击情形下,靠近受保护端口布局,减小寄生电感;
  • 若连续或重复冲击频繁,应评估热累积并考虑外加散热措施或并联器件分担能量。

六、选型与使用注意事项

  • 工作电压裕量:Vrwm(24V)应高于常态工作电压,保留一定裕量以避免误触发;
  • 钳位与耐受能力:确认在最大冲击条件下 Vc 不超过被保护器件允许最高电压;
  • 冲击波形与测试条件:Ipp 与 Ppp 通常基于特定波形(例如 10/1000 μs 等),选型时核对数据手册中的测试波形与条件;
  • 极性与安装:单向/双向型号极性不同,安装前核对型号后缀与原理图要求。

七、可靠性与环境适应

5.0SMDJ24CA 设计用于工业级和苛刻环境,支持宽温范围和高瞬态能量。建议在关键应用中参考完整可靠性试验(如温度循环、湿热、振动)报告,并在最终产品认证(例如汽车级 ISO/TS 或 AEC-Q 要求)中验证器件是否满足相应标准。

Sourcing availability signal

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
