SMCJ26CA 瞬态抑制二极管(TVS)产品概述

一、产品基本定位

SMCJ26CA是一款双向瞬态抑制二极管(TVS),由国内专业过压保护厂商RUILON(瑞隆源)研发生产,采用SMC(DO-214AB)表面贴装封装。该器件专为电子电路的瞬态过压防护设计,可有效抑制雷电、静电放电(ESD)、开关浪涌等瞬态脉冲干扰,保障通信、工业、汽车等领域敏感元器件的安全运行。

二、核心参数详解

SMCJ26CA的参数针对低压系统过压保护做了精准优化,核心指标如下:

2.1 极性与截止特性

  • 极性:双向:无需区分正负极,可直接并联在电路两端,简化PCB设计与装配流程;
  • 反向截止电压(Vrwm):26V:正常工作状态下,器件反向漏电流极小,不影响电路正常功能,适配12V、24V等低压系统。

2.2 保护关键参数

  • 击穿电压:33.2V:电路过压时,器件首先在该电压下导通,启动保护机制;
  • 钳位电压:42.1V:脉冲峰值时,将电压钳位在42.1V以内,确保后级IC、传感器等敏感元件不被损坏;
  • 峰值脉冲电流(Ipp):35.7A:可承受的最大瞬态脉冲电流,覆盖多数常见浪涌干扰场景;
  • 峰值脉冲功率(Ppp):1.5kW@10/1000μs:符合IEC标准的10/1000μs浪涌波形下,功率耐受能力达1.5kW,满足通信、工业领域典型需求。

2.3 静态与环境参数

  • 反向漏电流(Ir):5μA:正常工作时漏电流极低,静态功耗可忽略,不影响电路效率;
  • 工作温度范围:-55℃~+150℃:宽温设计,适应工业现场、汽车电子等极端温度环境。

三、封装与品牌优势

3.1 封装特性

SMCJ26CA采用SMC(DO-214AB)表面贴装封装,尺寸紧凑(约6.0×5.2×2.3mm),适合高密度PCB布局;支持回流焊、波峰焊等自动化工艺,生产效率高;封装材料耐高温,长期可靠性强。

3.2 品牌背景

RUILON(瑞隆源)是国内专注于过压保护器件的专业厂商,产品覆盖TVS、压敏电阻、ESD保护器等系列,广泛应用于通信、工业、汽车、消费电子领域。SMCJ26CA符合RoHS环保标准,质量稳定,性价比突出。

四、典型应用场景

SMCJ26CA因双向保护、宽温耐受、高脉冲功率等特性,适用于以下场景:

  1. 通信设备:基站、路由器、交换机的以太网接口、射频接口保护;
  2. 工业控制:PLC、传感器、伺服驱动器的输入输出端口防护;
  3. 汽车电子:12V辅助电路(中控、胎压监测、摄像头)的瞬态浪涌保护;
  4. 消费电子:智能手机、平板、笔记本的USB接口、充电端口ESD/浪涌防护;
  5. 电力系统:LED驱动电源、开关电源的低压配电过压防护。

五、产品性能优势

  1. 双向保护,设计简单:无需考虑极性,并联即可实现正反向过压保护,降低电路复杂度;
  2. 高脉冲耐受,可靠性强:1.5kW峰值功率与35.7A峰值电流,应对雷电、开关浪涌等强干扰;
  3. 低漏电流,低功耗:5μA反向漏电流,静态下不影响电路正常工作;
  4. 宽温范围,环境适应:-55℃~+150℃工作温度,满足工业、汽车极端环境需求;
  5. 紧凑封装,易集成:SMC封装尺寸小,适合高密度PCB,支持自动化生产。

六、选型与使用注意事项

  1. 电压匹配:反向截止电压(26V)需与电路正常电压匹配(建议≤24V),避免误导通;
  2. 功率评估:若实际浪涌功率超过1.5kW,可并联多个器件提升耐受能力;
  3. 焊接工艺:回流焊峰值温度≤260℃,时间≤30s,避免封装损坏;
  4. 布局建议:尽可能靠近被保护端口并联,减少引线电感,提升保护效果。

SMCJ26CA凭借稳定的保护性能与灵活的应用场景,成为低压系统过压防护的主流选择之一。

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
