CJSMCJ36CA 产品概述

一、产品简介

CJSMCJ36CA 是江苏长电/长晶(CJ)出品的一款双向瞬态电压抑制器(TVS),采用 SMCG 封装,专为抑制电源和信号线上突发过压浪涌而设计。器件对高能量脉冲具有良好的吸收能力,能够在短时雷击、开关脉冲或电磁干扰引起的过压事件中保护后端电路,适用于工业与通信电源保护场景。

二、主要电气参数

  • 极性:双向(Bidirectional),无需明确极性方向,适合交流耦合或双向浪涌情况
  • 反向截止电压 Vrwm:36 V(推荐直流工作电压参考值)
  • 钳位电压 Vcl:57.5 V(在规定脉冲条件下的最大钳位)
  • 峰值脉冲电流 Ipp:25.9 A @ 10/1000 μs(脉冲波形10/1000μs标准)
  • 峰值脉冲功率 Ppp:1.5 kW @ 10/1000 μs
  • 击穿电压 Vbr:44.17 V(典型或测试条件下测得)
  • 反向电流 Ir:5 μA(常温下低漏电流,有利于节能与热稳定)
  • 工作温度范围:-55 ℃ ~ +150 ℃
  • 类型:TVS;封装:SMCG;品牌:CJ(江苏长电/长晶)

三、性能特点与优势

  • 高能量吸收:在10/1000 μs脉冲下可承受25.9 A 的峰值脉冲电流与1.5 kW 的瞬态功率,适合抗雷击和大能量浪涌场合。
  • 双向保护:对正负方向过压均能进行钳位保护,适用于交流耦合、信号线或双向电源线路。
  • 低漏电流:5 μA 的反向电流有助于降低静态损耗与热升,提高系统稳定性。
  • 宽温性能:-55 ℃ 至 +150 ℃ 的工作温度区间,适配工业级温度要求。
  • 紧凑封装:SMCG 封装便于表面贴装,适合自动化贴装与批量生产。

四、典型应用场景

  • 工业24 V电源总线保护:对24 V系统的浪涌与雷击提供二次防护,Vrwm 36 V 适合在 24 V 工况下使用。
  • 通信与基站设备:电源入口、放大器前端及数据接口的过压防护。
  • 可再生能源与逆变器外围保护:光伏逆变器或风机控制单元的线路浪涌抑制。
  • 电力控制与自动化设备:PLC、驱动器及传感器接口保护。
  • 消费电子与充电设备:高能量脉冲场合需二级保护时可选用。

五、封装与应用注意事项

  • 封装与热管理:SMCG 为表面贴装形式,布局时应注意器件底面散热路径,必要时在焊盘下设置热过孔或加铜皮以提高散热能力。
  • 焊接工艺:遵循元件供应商给出的回流焊温度窗口,避免过高温度或长时间加热导致封装应力。
  • 布局建议:浪涌源端应尽量缩短导线与回流路径,保护元件应靠近被保护端口放置;与浪涌能量相关的阻抗匹配和接地设计直接影响抑制效果。
  • 极性说明:双向器件无特定极性标记要求,但在电路上仍需按数据手册推荐的方向与焊盘布局安装。

六、选型建议

  • 工作电压匹配:选择 Vrwm 时应保证其高于正常工作电压但留有足够裕量,36 V Vrwm 非常适合标称24 V 系统。
  • 能量余量评估:根据系统可能出现的最大浪涌能量与脉冲波形,确认 Ipp 与 Ppp 能否满足最坏工况;必要时可并联或串联多只 TVS 或选择更高功率型号。
  • 温度与可靠性:若长期在高温环境运行,应关注封装热阻和长期漂移特性,并在可靠性评估中考虑温升影响。

七、结论

CJSMCJ36CA 为一款面向中高能量瞬态抑制的双向 TVS 器件,凭借 36 V 的 Vrwm、57.5 V 的钳位电压以及在 10/1000 μs 条件下 25.9 A 的抗冲击能力,适用于工业电源与通信等需要高能量浪涌保护的场景。在实际应用中,应结合系统工作电压、预期浪涌能量和散热条件进行选型与版图优化,以获得最佳保护效果与长期可靠性。若需更详细的典型曲线、封装图或回流焊工艺参数,请参考厂商完整数据手册或向供货商索取样片测试。

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.
