SMCJ36CA 产品概述

一、产品简介

SMCJ36CA 是 RUILON(瑞隆源)推出的一款双向瞬态电压抑制器(TVS),采用 DO-214AB(SMC)表面贴装封装。器件专为抑制瞬态过电压和冲击脉冲设计,可在工业与汽车类等恶劣电磁环境中保护敏感电子元件和电源系统,提供可靠的浪涌抑制能力与宽温度范围的长期稳定性。

二、主要电气参数

  • 钳位电压(VCL):58.1 V(在规定测试条件下)
  • 击穿电压(VBR):46 V
  • 反向截止电压(Vrwm,稳压电压):36 V(适合作为电路连续工作电压上限)
  • 峰值脉冲功率(Ppp):1.5 kW(瞬态脉冲能力,实际能量与脉冲波形/宽度相关)
  • 峰值脉冲电流(Ipp):25.9 A
  • 反向漏电流(Ir):5 μA(常温)
  • 极性:双向(适用于交流或无极性线路)
  • 工作温度:−55 °C ~ +150 °C
  • 封装:DO-214AB(SMC)

三、器件特点与优势

  • 强劲的瞬态吸收能力:1.5 kW 峰值脉冲功率和 25.9 A 峰值脉冲电流,使其能有效钳位并吸收来自雷击、开关瞬变等产生的高能脉冲。
  • 双向保护:对正负极性瞬态都能对称钳位,适合交流波形或需双向保护的直流系统。
  • 低漏电流与宽温区间:5 μA 的漏电在大多数待机或灵敏电路中影响极小;−55~+150 °C 的工作范围满足工业级可靠性需求。
  • SMC 封装利于散热与可靠焊接,适合大功率吸收场合。

四、典型应用场景

  • 工业控制设备与PLC的电源与信号保护;
  • 通信与基站接口保护;
  • 电动工具、逆变器和电池管理系统的浪涌防护;
  • 较高电压直流或低压交流系统(例如 24 V/36 V 工业总线)中的输入/输出端浪涌抑制;
  • 其他需双向钳位的电源或信号线路保护场合。

五、选型与使用建议

  • 确定稳态电压:Vrwm(36 V)应高于电路的最大正常工作电压,确保长期可靠运行。
  • 关注脉冲波形与能量:Ppp 与 Ipp 与测试波形(如 8/20 μs、10/1000 μs)相关,设计时以原厂数据手册给出的测试条件为准并留有安全余量。
  • PCB 布局与散热:SMC 封装在高能量吸收时会产生较大热量,建议增大铜箔散热区并缩短走线以降低寄生电感,必要时靠近被保护端点布局。
  • 保护与熔断配合:在高能脉冲或反复冲击场合,建议配合合适的熔断器或限流元件,避免单独依赖 TVS 长期承受超过其重复能力的能量。
  • 并联与替代:并联使用需谨慎,若需更高能量吸收优先选用额定更高的型号或专用浪涌抑制器。

六、封装与可靠性提醒

DO-214AB(SMC)为表面贴装大功率封装,焊接时注意遵循回流温度曲线及焊盘设计规范以保证焊点可靠性。长期在高温或频繁冲击环境下工作时,应参考厂方老化与循环测试数据,必要时在样机上进行系统级寿命验证。

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
