SMCJ15CA瞬态抑制二极管(TVS)产品概述

一、产品基本定位与标识

SMCJ15CA是RUILON(瑞隆源)品牌推出的双向瞬态抑制二极管(TVS),属于贴片式过压保护器件,核心作用是快速响应瞬态过压脉冲(如雷击、静电放电、电源浪涌),保护后端敏感电子元器件免受损坏。其型号中:

  • “SMCJ”代表SMC封装(DO-214AB)的TVS系列;
  • “15”对应反向截止电压15V;
  • “CA”标识双向极性(无正负极区分)。

二、核心电性能参数详解

该器件关键参数围绕“过压防护能力”与“工作稳定性”设计,具体如下:

参数名称 数值/条件 作用说明 反向截止电压(Vrwm) 15V 正常工作时可承受的最大直流/峰值交流电压,避免器件误触发 击穿电压(Vbr) 18.5V 电压超过此值时,器件进入导通状态,启动过压抑制 钳位电压(Vc) 24.4V 峰值脉冲下的最大电压降,直接决定后端器件的保护阈值 峰值脉冲电流(Ipp) 61.5A@10/1000μs 工业标准浪涌波形(上升沿10μs、半峰值1000μs)下的最大耐受电流 峰值脉冲功率(Ppp) 1.5kW@10/1000μs 浪涌功率容量,反映器件的浪涌耐受能力 反向漏电流(Ir) 1μA(额定电压下) 正常工作时的泄漏电流,数值小则系统功耗损耗低

三、封装形式与物理特性

SMCJ15CA采用SMC(DO-214AB)贴片封装,具备以下特点:

  1. 小体积:典型尺寸为3.2mm×2.5mm×1.5mm,适配高密度PCB布局(如小型化消费电子、物联网终端);
  2. 焊接兼容:支持回流焊、波峰焊等自动化工艺,生产效率高;
  3. 无极性安装:双向器件无需区分正负极,简化设计与组装流程;
  4. 引脚可靠性:封装引脚与PCB焊接牢固,抗振动性能满足工业级要求。

四、典型应用场景

该器件针对低电压系统的过压防护需求,广泛应用于:

1. 电源电路保护

  • 12V/15V直流电源系统(如便携式设备、工业控制器)的浪涌防护;
  • 电池供电设备(如智能手环、物联网传感器)的过充/过放瞬态抑制。

2. 通信接口防护

  • RS485、CAN总线等工业通信接口的ESD与浪涌防护(符合IEC 61000-4-5标准);
  • USB、以太网等高速接口的静电放电(ESD)抑制(满足IEC 61000-4-2标准)。

3. 工业与汽车电子

  • 工业PLC、传感器模块的过压保护;
  • 汽车低压系统(如车载音响、胎压传感器)的瞬态干扰抑制(适配宽温环境)。

4. 消费电子

  • 智能手机、平板的充电端口ESD防护;
  • 智能家居设备(如智能插座、摄像头)的电源与通信接口浪涌防护。

五、关键技术特性与优势

  1. 双向防护:无极性设计,兼容交流/直流双向过压场景,安装灵活;
  2. 快速响应:TVS典型响应时间<1ns,可瞬间抑制瞬态脉冲(如ESD);
  3. 高浪涌容量:1.5kW峰值功率覆盖多数低电压系统的浪涌需求;
  4. 低功耗损耗:1μA反向漏电流对系统正常工作影响极小;
  5. 宽温可靠性:-55℃~+150℃工作温度范围,适用于户外、高温工业环境;
  6. 成本效益:小体积封装与成熟工艺结合,兼顾防护性能与成本控制。

六、选型与应用注意事项

  1. 电压匹配:Vrwm需≥系统正常工作电压(如15V系统优先选Vrwm15V),避免误触发;
  2. 功率匹配:需根据系统最大浪涌功率选择型号,确保Ppp覆盖实际需求;
  3. 布局原则:尽量靠近被保护器件/接口端,减少引线电感对防护效果的影响;
  4. 温度验证:极端温度(如+150℃)下需确认器件性能稳定性;
  5. 极性确认:本型号为双向,无需区分正负极,单向TVS需严格核对极性。

SMCJ15CA凭借双向防护、小体积、宽温可靠等特性,成为低电压系统过压保护的主流选型之一,适用于从消费电子到工业控制的多场景需求。

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
