Brightking SMBJ160A/TR13 单向TVS瞬态抑制二极管产品概述

一、产品定位与核心功能

SMBJ160A/TR13是台湾君耀(Brightking)推出的单向瞬态抑制二极管(TVS),属于表面贴装式过压防护器件,核心定位是为中低压电路提供快速、可靠的浪涌电压抑制,适配对空间紧凑、自动化贴装要求高的电子设备设计。其通过反向击穿特性,在电路遭遇瞬态过压时快速导通,将电压钳位在安全范围内,避免后端敏感元器件(如IC、传感器)因过压损坏。

二、关键电气参数深度解析

该器件的核心参数围绕“浪涌防护能力”与“正常工作稳定性”设计,关键参数含义如下:

  • 反向截止电压(Vrwm=160V):电路正常工作时,反向可承受的最大直流/交流电压,确保器件不击穿,避免静态漏电流影响电路性能;
  • 击穿电压(Vbr=178V):反向击穿的典型阈值,当电路电压超过此值时,TVS管从高阻态快速切换为低阻态,启动防护;
  • 钳位电压(Vc=259V):在额定峰值脉冲电流(Ipp)下,器件两端的最大电压,是防护时后端电路实际承受的最高电压,需低于敏感元器件的耐压极限;
  • 峰值脉冲电流(Ipp=2.3A):能承受的单次8/20μs浪涌脉冲的最大电流,结合钳位电压计算得峰值脉冲功率(Ppp=Vc×Ipp≈600W),即器件的浪涌功率容量;
  • 反向漏电流(Ir=1μA):正常工作电压下的反向漏电流,远低于常见器件的漏电流水平,可忽略对电路功耗的影响。

三、封装设计与可靠性优势

SMBJ160A/TR13采用SMB封装(DO-214AA),具备以下设计优势:

  1. 小尺寸适配自动化生产:封装尺寸约为2.3mm(宽)×5.3mm(长)×1.0mm(高),占用PCB面积小,适合高密度贴装;支持回流焊、波峰焊等自动化工艺,生产效率高;
  2. 单向极性明确:封装上印有极性标识(如色环或丝印),便于焊接时识别方向,避免接反导致防护失效;
  3. 环境适应性强:封装材料采用耐高温环氧树脂,可承受-55℃~+150℃的工作温度范围,满足工业级、消费电子的环境要求;抗机械冲击与振动性能符合行业标准,适合移动设备或振动环境下的应用。

四、品牌与品质保障

Brightking(君耀)作为专注于过压防护器件的台企,在TVS、压敏电阻等领域拥有20余年研发生产经验,SMBJ160A/TR13具备以下品质优势:

  • 参数一致性好:批量生产中,击穿电压、钳位电压等关键参数偏差控制在±5%以内,确保不同批次器件防护性能稳定;
  • 环保与认证:符合RoHS 2.0、REACH等环保指令,无铅无卤;部分型号通过UL、VDE等国际安全认证,可满足出口或高端设备的认证要求;
  • 可靠性验证:经过高温老化、浪涌寿命测试(如多次承受额定浪涌脉冲后性能无衰减),适合长期在恶劣环境下工作。

五、典型应用场景

SMBJ160A/TR13的参数特性使其适用于多类中低压电路的过压防护:

  1. 工业控制设备:PLC(可编程逻辑控制器)的输入输出端口、传感器接口、电源模块,防护电网浪涌或静电放电(ESD);
  2. 通信设备:路由器、交换机的以太网端口、光模块电源,应对雷击浪涌或线路过压;
  3. 消费电子:智能家电(如空调、洗衣机)的控制板电源、显示屏接口,保护内部MCU、显示驱动芯片;
  4. 医疗设备:小型医疗仪器的电源端口、传感器电路,确保设备在电网波动下稳定工作。

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
