RUILON SMAJ5.0CA 型号 TVS 二极管 产品概述

一、产品简介

SMAJ5.0CA 为 RUILON(瑞隆源)出品的双向瞬态电压抑制器(TVS),封装为 DO-214AC(SMA)。器件针对 5V 等低压电路的浪涌与静电脉冲提供可靠保护,具有较低钳位电压与高脉冲吸收能力,适合工业控制、通信接口、线缆入口及一般电源防护场合。

主要电气参数(典型/额定):

  • 极性:双向(Bi‑directional)
  • 反向额定工作电压 Vrwm:5V
  • 击穿电压(Vbr):7.25V
  • 钳位电压 Vc(典型):9.2V
  • 峰值脉冲电流 Ipp:43.5A @ 10/1000μs
  • 峰值脉冲功率 Ppp:400W @ 10/1000μs
  • 反向泄漏电流 Ir:800μA
  • 工作温度范围:-55℃ ~ +150℃
  • 防护等级:符合 IEC 61000-4-4(瞬态)与 IEC 61000-4-2(静电放电)标准

二、关键特性与优势

  • 双向结构:能同时抑制正负方向的瞬态脉冲,适用于交流或差分信号线以及无明确极性的接口。
  • 低钳位:9.2V 的典型钳位电压可在浪涌时有效限制被保护电路承受的电压应力。
  • 高能量吸收:10/1000μs 波形下 400W 峰值功率与 43.5A 峰值电流,适合电源突入与雷击引起的长尾脉冲。
  • 宽温度范围:-55℃~+150℃ 可满足苛刻环境中的可靠性需求。
  • 封装可靠:SMA(DO‑214AC)为常见表贴封装,便于量产装配与维修更换。

三、应用场景

  • 5V 电源总线、USB 与串行接口的浪涌与 ESD 防护。
  • 工业控制与自动化设备的输入输出端保护。
  • 通信设备、监控摄像头、POE 辅助线路(需根据系统电压选择)等对瞬态抑制有要求的场合。

四、选型与使用建议

  • 钳位匹配:选择钳位电压应确保在最大冲击下被保护器件的耐压之下,同时留有安全裕量。SMAJ5.0CA 钳位约 9.2V,适合 5V 级负载。
  • PCB 布局:将 TVS 靠近被保护端口放置,走线尽量短且宽,减小回路电感以提高抑制效果。
  • 热管理:长时间或重复脉冲会产生热量,应评估工作环境与散热条件,必要时增加散热铜箔或序列电阻以分担能量。
  • 安装注意:遵循制造商的回流焊工艺要求,避免超过封装可承受的温度与时间。

五、可靠性与测试

SMAJ5.0CA 已针对 IEC 61000‑4‑2(ESD)与 IEC 61000‑4‑4(脉冲群)等工业级抗扰度标准进行设计与测试,能提供稳健的瞬态保护效果。实际系统中建议结合浪涌试验与 ESD 试验验证整体防护性能,并做必要的老化与循环测试以评估长期可靠性。

六、注意事项

  • 本器件为防护用元件,不应用作稳压器;长期承受高电流脉冲会缩短寿命。
  • 选择时应综合考虑工作电压、最大允许泄漏、钳位电平与能量吸收能力。
  • 对关键应用建议与供应商确认样片测试数据与可靠性报告。

SMAJ5.0CA 以其低钳位、高能量吸收与工业级温度与抗扰度特性,是保护 5V 级电路免受瞬态冲击的实用选择。若需器件数据表(Datasheet)、典型波形或 PCB 推荐封装尺寸图,可进一步提供以便工程实现。

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
