SMAJ5.0CA 产品概述

一、产品简介

SMAJ5.0CA 是 ElecSuper(静芯微)推出的一款双向瞬态抑制二极管(TVS),采用 DO-214AC(SMA)封装,提供对5V工作电源及信号线的瞬态过压保护。器件设计用于吸收外来浪涌与静电放电能量,保护下游电子元件免受瞬态电压损伤,适合通信、工业控制、仪表及消费电子等领域。

二、主要参数

  • 极性:双向(Bidirectional)
  • 额定反向稳态电压 Vrwm:5V
  • 钳位电压 Vc(峰值):9.2V
  • 峰值脉冲电流 Ipp:43.5A
  • 峰值脉冲功率 Ppp:400W
  • 击穿电压 Vbr:6.4V
  • 反向漏电流 Ir:≤400 µA(在 Vrwm 条件下)
  • 通道数:单路
  • 工作温度:-65℃ 至 +150℃
  • 防护等级:符合 IEC 61000-4-2 静电放电防护要求
  • 封装:DO-214AC(SMA)

三、性能与特点

  • 强劲的瞬态吸收能力:400W 峰值脉冲功率与 43.5A 峰值冲击电流,使其能有效承受较大幅度的浪涌与 ESD 冲击。
  • 低钳位电压:9.2V 的钳位水平在保护敏感 5V 系统时能显著降低被保护节点上的剩余电压,减小对下游器件的应力。
  • 宽工作温度范围:-65℃~+150℃,适应严苛工业环境。
  • 双向保护:无需区分正负方向,适合交流或可反向瞬态的场合,安装更灵活。
  • 坚固封装:SMA 封装便于表面贴装,散热与可靠性良好,适合批量生产与自动化贴装。

四、典型应用场景

  • 5V 电源输入与分配总线的瞬态保护
  • USB、串口、I/O 接口的 ESD 与浪涌防护
  • 工业控制器、PLC、仪表等对瞬态抑制要求较高的模块
  • 通信设备与嵌入式系统的接口保护

五、安装与使用建议

  • 布局建议:将 TVS 芯片尽量靠近被保护端口或连接处,信号线保持最短路径,减小串联电感与回路面积,以保证快速钳位。
  • 焊接注意:遵循 DO-214AC 的回流焊工艺规范,避免过长加热或反复加热以免影响器件性能。
  • 电路保护配合:TVS 适用于瞬态能量吸收,不用于长时间限流或连续工作;在可能出现持续过压的系统中,应配合熔断器、限流电阻或稳压元件使用。
  • 热管理:在高脉冲功率场合,应考虑 PCB 铜箔面积与散热路径,防止过热导致失效。

六、可靠性与存储

  • 此器件满足 IEC 61000-4-2 对静电放电的防护能力,适用于对 ESD 有严格要求的应用环境。
  • 存储与搬运时请注意防静电措施,避免长时间潮湿环境保存;建议按厂方出厂包装条件保存并尽快使用以保持最佳性能。
  • 使用前请参考厂方完整数据手册,注意测试条件(如脉冲波形、测量电流与电压条件)对参数的影响。

总结:SMAJ5.0CA 以其高能量吸收能力、低钳位电压与宽温度范围,适合为 5V 系统和接口提供可靠的瞬态过压保护,是工业与消费电子中常见的防护选择。有关详细电气特性和典型波形,请参阅厂方数据手册以便在具体设计中精确选型与验证。

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
