Brightking SMCJ170CA/TR13 双向瞬态抑制二极管(TVS)产品概述

一、产品核心身份与定位

Brightking(台湾君耀)SMCJ170CA/TR13是一款双向瞬态抑制二极管(TVS),属于电路过压保护器件,专为应对瞬态浪涌(如雷击、静电放电、开关尖峰等)设计,可快速将异常高压钳位至安全范围,保护后级敏感电子元件(如MCU、传感器、通信芯片)。料号后缀“TR13”对应卷带编带封装,适配自动化表面贴装生产线,满足批量生产需求。

二、关键电气参数深度解析

作为TVS的核心性能指标,SMCJ170CA/TR13的参数针对性强,覆盖多场景过压保护需求:

  1. 极性与电压耐受基础:
    采用双向设计,无需区分正负极,电路布局更灵活;反向截止电压(Vrwm)为170V(正常工作可长期承受的最大反向电压),典型击穿电压(Vbr)为189V(比Vrwm高11%,避免正常电压波动误导通)。
  2. 浪涌钳位能力:
    峰值脉冲钳位电压(Vc)为275V(浪涌下能限制的最高电压,远低于敏感元件击穿阈值);峰值脉冲电流(Ipp)达5.5A,峰值脉冲功率(Ppp)达1.5kW,可应对常见浪涌冲击(如工业开关尖峰、雷击干扰)。
  3. 静态功耗控制:
    反向漏电流(Ir)仅1μA(@Vrwm下),正常工作时漏电流极小,几乎不消耗系统功率,不影响设备能效。

三、封装与物理特性

SMCJ170CA/TR13采用SMC(DO-214AB)表面贴装封装,是行业标准小型封装:

  • 体积紧凑(典型尺寸5.8mm×3.8mm×2.3mm),适配高密度PCB设计,满足消费电子、工业控制的小型化需求;
  • 表面贴装引脚,支持回流焊工艺,生产效率高,适合批量制造;
  • 封装材料耐高温、耐潮湿,符合RoHS环保标准,可用于各类电子设备。

四、典型应用场景

结合电压参数与封装特性,主要应用场景包括:

  1. 工业控制:PLC、传感器模块、电机驱动的电源/信号线路保护,应对开关浪涌与雷击;
  2. 电源系统:中高压直流电源(光伏逆变器、UPS)输出端保护,防止瞬态电压损坏负载;
  3. 通信设备:路由器、交换机、基站的通信接口(以太网、光纤)保护,抵御静电与浪涌;
  4. 消费电子:高端家电、智能安防设备的电源线路保护(高压应用场景)。

五、产品优势与市场价值

  1. 双向保护简化设计:无需区分正负极,降低布局复杂度与接线错误风险;
  2. 高可靠性:Brightking作为台湾老牌厂商,产品经严格可靠性测试(温度循环、湿度老化),性能稳定,供货可控;
  3. 小封装适配多场景:体积小可集成到小型化设备,同时支持自动化生产,降低制造成本;
  4. 中高压场景匹配:170V Vrwm与275V钳位电压,填补传统低压TVS的应用盲区,适合中高压电路保护。

六、应用注意事项

  1. 选型匹配:确保Vrwm(170V)高于系统正常工作电压峰值(如220V交流峰值311V,需注意直流/低压峰值场景);
  2. 并联扩容:单颗功率不足时可并联多颗,但需添加限流电阻实现均流;
  3. 焊接规范:遵循SMC封装回流焊曲线(峰值温度≈260℃,时间≤30秒),避免高温损坏;
  4. 安装位置:尽可能靠近被保护电路输入端,减少引线电感对保护效果的影响。

SMCJ170CA/TR13凭借双向保护、高脉冲耐受与小封装优势,成为中高压电路过压保护的高性价比选择,可广泛应用于工业、通信、消费电子等领域。

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
