SMCJ7.0CA/TR13 TVS二极管产品概述

一、产品基本定位

SMCJ7.0CA/TR13是台湾君耀(Brightking)推出的双向瞬态抑制二极管(TVS),核心作用是快速抑制电路中的瞬态过压(如雷击、静电放电、开关浪涌等),将电压钳位在安全范围,避免后级敏感元件(IC、传感器等)损坏。该器件采用SMC(DO-214AB)表面贴装封装,体积小巧,适配高密度PCB布局,广泛应用于消费电子、工业控制、通信等领域。

二、核心电气参数详解

各参数直接决定防护能力,具体意义如下:

  1. 极性双向:无需区分正负,可同时防护正向/反向瞬态脉冲,简化电路设计;
  2. 反向截止电压(Vrwm)7V:电路正常工作时,该电压下器件截止,漏电流极小,不影响电路运行;
  3. 钳位电压12V:瞬态浪涌时快速击穿,将电压钳位在12V以内,确保后级元件(如耐压15V的IC)安全;
  4. 峰值脉冲电流(Ipp)125A:10/1000μs标准浪涌波形下,单次可承受最大电流,应对较强浪涌冲击;
  5. 峰值脉冲功率(Ppp)1.5kW:同波形下最大承受功率,满足多数工业/消费场景防护需求;
  6. 击穿电压8.6V:反向击穿典型值,介于Vrwm(7V)和钳位电压(12V)之间,响应及时;
  7. 反向漏电流(Ir)200μA:7V截止电压下漏电流,数值小,对电路功耗影响可忽略;
  8. 工作温度-65℃~+150℃:宽温特性,适配高温(如工业炉)或低温(如户外通信)环境。

三、封装与物理特性

采用SMC(DO-214AB)封装,尺寸约3.2mm×2.4mm×1.8mm,引脚间距1.27mm,适合自动化贴装。塑料封装绝缘性、耐腐蚀性好,单次脉冲后热量可快速消散,无需额外散热片,适合高密度PCB布局。

四、典型应用场景

  1. 消费电子:手机、平板、笔记本的USB接口、充电端口防护,抵御静电/充电浪涌;
  2. 工业控制:PLC模块、传感器节点、电机驱动的电源/信号端口防护,应对开关浪涌;
  3. 通信设备:路由器、交换机的以太网接口、POE端口防护,抵御雷击/线路浪涌;
  4. 低压电源:12V直流电源(LED驱动、安防监控)输出端防护,防止负载短路/切换浪涌;
  5. 汽车电子(部分场景):-65℃~150℃宽温,适配汽车仪表、辅助驾驶传感器的低电压防护(需确认汽车级认证)。

五、品牌与可靠性

台湾君耀(Brightking)是全球知名保护器件厂商,产品符合IEC 61000-4-2(ESD)、IEC 61000-4-5(浪涌)等标准,经高温存储(150℃×1000h)、温度循环(-65℃~150℃×1000次)等验证,长期稳定可靠。

六、选型与使用注意事项

  1. 参数匹配:Vrwm略高于电路正常电压(如5V电路选7V),钳位电压低于后级元件耐压;
  2. 布线要求:靠近防护端口(如USB接口),减少引线长度(降低电感,提升响应速度);
  3. 脉冲频率:单次脉冲防护,高频脉冲需并联多器件或选高频TVS;
  4. 极性安装:双向无需区分正负,任意方向贴装,简化生产。

该器件以平衡的防护能力、宽温特性和紧凑封装,成为低压电路过压防护的高性价比选择。

Sourcing availability signal

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
