RUILON SMAJ36CA(SMA 封装)产品概述

一、产品简介

SMAJ36CA 是 RUILON(瑞隆源)推出的一款双向瞬态电压抑制器(TVS),采用 DO-214AC(SMA)表面贴装封装,专为36V 顶限工况的浪涌/静电防护设计。器件在 10/1000µs 脉冲波形下可承受高达 400W 峰值脉冲功率,适用于工业、电源输入、通信接口及汽车电子等需要稳健过压防护的场景。

二、主要电气参数

  • 钳位电压(Vc):58.1 V(对应峰值脉冲电流 Ipp)
  • 峰值脉冲电流(Ipp):6.9 A(10/1000µs)
  • 峰值脉冲功率(Ppp):400 W @ 10/1000µs
  • 反向工作电压(Vrwm / 截止电压):36 V
  • 击穿电压(Vbr):46 V
  • 反向漏电流(Ir):1 µA(典型/最大等级,按 Vrwm 测试)
  • 极性:双向(Bidirectional)
  • 工作温度范围:-55 ℃ ~ +150 ℃
  • 防护等级/认证:符合 IEC 61000-4-2(ESD)、IEC 61000-4-4(EFT)标准
  • 封装:DO-214AC(SMA)

三、性能特点

  • 高能量吸收能力:10/1000µs 条件下 400W 峰值功率,能有效吸收高能浪涌能量。
  • 精准钳位:钳位电压 58.1V 与 Ipp 6.9A 配合,可在浪涌时快速夹紧电压,保护后级器件。
  • 双向保护:对正负极性瞬态均能防护,适合交流或可能出现反向电压的线路。
  • 宽温度工作:-55℃ 至 +150℃,适应恶劣环境与汽车级温度要求。
  • 低漏电流:Vrwm 下漏电仅 1µA,降低待机损耗与功耗影响。
  • 表面贴装封装:SMA 封装便于自动化贴装,适合标准 PCB 组装工艺。

四、典型应用场景

  • 电源输入端的浪涌保护(24V/36V 工业电源、逆变器控制部分)
  • 通信接口和数据线的瞬态抑制(串口、电表接口等)
  • 汽车电子低压系统的瞬态防护(适合车规级温度范围的应用)
  • 工业控制设备、仪表及楼宇自控系统的电磁兼容(EMC)防护
  • 配合滤波器用于加强对 ESD 与 EFT 冲击的抗扰能力

五、封装与布局建议

  • SMA(DO-214AC)为表面贴装器件,推荐靠近需保护的连接器或器件焊接,尽量缩短线路路径以降低寄生电感。
  • 为充分散热与承受高能量,PCB 板上应留有适当的铜箔散热区,并遵循厂商的焊盘尺寸和回流规范。
  • 在地线布线时优先采用单点或短回路地,避免将浪涌电流通过敏感电路路径。
  • 对于高频或高速信号线,若需要并联 TVS,请注意其电容值对信号完整性的影响(选择低电容款或在非关键高速线上使用)。

六、选型与使用建议

  • 确认系统常态最大工作电压 ≤ Vrwm(36V),以避免器件长期偏置造成热量或漏电问题。
  • 若系统可能承受短时更大电流或更陡浪涌,需核对脉冲波形(10/1000µs)是否与实际环境匹配,必要时考虑额外串联阻抗或更高能量等级器件。
  • 在并联多个 TVS 时注意热均匀与功率共享,避免单个器件超载。
  • 对汽车或关键系统,建议参考供应商详细器件规范书(Datasheet)进行温升、循环寿命和剪裁试验验证。

SMAJ36CA 以其较高的吸收功率、双向防护与宽温度范围,适合对 36V 等级线路进行可靠的瞬态过压保护。选择与布局合理匹配,可显著提升系统的抗浪涌与抗静电干扰能力。

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
