Brightking SMCJ170A/TR13 TVS二极管产品概述

一、产品核心定位

SMCJ170A/TR13是台湾君耀(Brightking)推出的单向瞬态电压抑制二极管(TVS),采用SMC(DO-214AB)表面贴装封装,专为中高压电路的瞬态过压防护设计。其核心功能是在电路遭遇雷击、开关浪涌、静电放电(ESD)等瞬态脉冲时,快速导通并钳位电压,避免后级敏感元器件(如微控制器、传感器、通信接口芯片等)被击穿损坏,广泛适配工业控制、汽车电子、通信设备等领域的防护需求。

二、关键参数详解

该器件的参数围绕“过压防护可靠性”优化,核心指标及意义如下:

1. 电压类核心参数

  • 反向截止电压(Vrwm):170V
    电路正常工作时,反向偏置下不导通的最大电压,确保器件不干扰正常信号传输;
  • 击穿电压(Vbr):189V
    反向偏置下开始导通的电压,比Vrwm高19V,清晰界定“正常工作”与“防护触发”的边界;
  • 钳位电压(Vc):275V
    峰值脉冲电流下,器件两端能维持的最高电压,直接决定防护效果(远低于后级器件耐压阈值)。

2. 电流与功率参数

  • 峰值脉冲电流(Ipp):5.5A(8/20μs脉冲波形)
    单次瞬态脉冲能承受的最大电流,支撑中强度浪涌防护;
  • 峰值脉冲功率(Ppp):1.5kW
    单次脉冲的最大耗散功率,可有效抑制常见浪涌冲击;
  • 反向漏电流(Ir):1μA(Vrwm下)
    反向截止时漏电流极小,不影响电路正常功耗。

3. 环境与标准参数

  • 工作温度:-65℃~+150℃
    宽温范围覆盖工业、汽车等严苛环境(如汽车-40℃+125℃、工业-40℃+85℃);
  • 防护标准:IEC 61000-4-2
    符合静电放电防护要求,可抵御接触放电(8kV)、空气放电(15kV)等ESD冲击。

三、封装与品牌优势

1. SMC(DO-214AB)封装特点

该封装为表面贴装式,尺寸紧凑(约3.5mm×1.8mm×1.0mm),适合高密度PCB布局;引脚间距合理,兼容回流焊、波峰焊等自动化焊接工艺,且抗机械应力性能较好,适配批量生产。

2. Brightking品牌可靠性

台湾君耀是全球知名防护器件厂商,产品通过ISO/TS 16949、IEC等国际认证,一致性与稳定性突出;SMCJ系列采用优化芯片设计,多次浪涌冲击后性能无衰减,降低电路维护成本。

四、典型应用场景

结合参数与封装优势,SMCJ170A/TR13的典型应用包括:

  1. 工业控制电路:PLC输入输出接口、电机驱动电源、传感器信号线路,应对工业现场浪涌干扰;
  2. 汽车电子:车载DC-DC转换器、CAN总线接口、胎压监测系统(TPMS),适配汽车宽温环境;
  3. 通信设备:基站电源模块、以太网接口、光纤收发器,抵御雷击与ESD干扰;
  4. 电源模块:170V左右的直流/交流电源(如光伏逆变器辅助电源、工业电源),抑制开关浪涌。

五、性能特点总结

SMCJ170A/TR13的核心优势在于:宽温范围适配严苛环境、低漏电流不影响正常电路、高脉冲功率支撑中强度防护、SMC封装适合高密度设计。作为中高压TVS二极管,其在工业、汽车、通信等领域的过压防护中具有较强适用性,是替代同类进口器件的高性价比选择。

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
