Brightking(君耀)SMBJ36A/TR13 单向瞬态抑制二极管(TVS)产品概述

一、产品定位与核心价值

SMBJ36A/TR13是台湾君耀(Brightking)推出的小型表面贴装单向瞬态抑制二极管(TVS),属于SMB(DO-214AA)封装系列的经典防护型号。其核心价值在于以紧凑体积实现电子电路的瞬态过压保护,可有效吸收ESD(静电放电)、雷击感应浪涌、开关瞬态尖峰等干扰,避免MCU、传感器、通信芯片等敏感元器件因过压损坏,适配消费电子、工业控制、通信设备等领域的高密度PCB设计。

二、关键电气参数深度解析

该型号的核心参数直接决定防护能力,需结合应用场景精准理解:

  1. 极性与工作模式:单向设计,仅抑制某一方向的浪涌电压(通常为电路反向浪涌),需与被保护电路极性严格匹配;
  2. 反向截止电压(Vrwm):36V,是器件正常工作时可承受的最大反向直流电压,电路正常电压需低于此值(适配30V以下直流系统);
  3. 击穿电压(Vbr):40V(典型值),反向电压达40V时器件开始导通(反向电流约1mA),进入浪涌吸收准备状态;
  4. 钳位电压(Vc):58.1V(@10.4A峰值脉冲电流),是浪涌电流峰值时的电压限制值——被保护电路电压不会超过此值,为核心保护参数;
  5. 峰值脉冲电流(Ipp):10.4A,即器件能承受的最大浪涌电流峰值,对应峰值脉冲功率(Ppp)600W(计算值≈58.1V×10.4A≈604W,与标称一致);
  6. 反向漏电流(Ir):1μA(@Vrwm),正常工作漏电流极小,不影响电路功耗与稳定性。

三、封装与物理特性

SMB(DO-214AA)封装是该型号的核心优势:

  • 尺寸紧凑:标准尺寸约2.9mm(长)×5.0mm(宽)×2.4mm(高),适配便携设备等高密度PCB布局;
  • 表面贴装(SMT):兼容自动贴装生产线,生产效率高,焊接可靠性好;
  • 引脚设计:符合DO-214AA标准,焊盘间距合理,避免焊接短路;
  • 散热特性:瞬态浪涌功率600W的承受能力,满足多数中低功率电路防护需求(多次浪涌需注意PCB散热)。

四、典型应用场景

SMBJ36A/TR13的参数特性决定其适配场景:

  1. 消费电子:智能手机、平板、笔记本的USB/Type-C接口保护,防止充电浪涌与ESD;
  2. 工业控制:PLC输入输出模块、传感器节点、电机驱动电路的过压保护,应对开关浪涌与雷击感应;
  3. 通信设备:路由器、交换机、光模块的端口保护,抵御线路浪涌干扰;
  4. 低压电源系统:12V/24V直流电源输出端、电池管理系统(BMS)的过压防护,吸收开关电源瞬态尖峰。

五、品牌与可靠性保障

君耀(Brightking)作为台湾老牌半导体厂商,其SMBJ系列具备可靠质量:

  • 环保认证:符合RoHS 2.0、REACH等国际标准,无铅无卤;
  • 可靠性测试:经过温度循环(-55℃~150℃)、湿度老化(85℃/85%RH)、浪涌寿命测试,恶劣环境下稳定工作;
  • 市场验证:广泛应用于国内家电、通信、工业设备厂商,配套技术支持完善。

六、选型与使用注意事项

确保防护效果需注意:

  1. 极性匹配:单向TVS需与电路极性一致(反向接保护电路地端),接反失效;
  2. 电压余量:Vrwm需大于电路正常电压(留10%~20%余量,如电路28V选36V);
  3. 功率适配:浪涌超600W时,并联多个同型号器件(注意参数一致性);
  4. 焊接要求:采用回流焊工艺,避免手工焊接过热损坏;
  5. 散热设计:多次浪涌场景下,PCB增加散热铜箔降低器件温度。

该型号以高性价比、紧凑体积和可靠防护,成为中低功率电路过压保护的主流选择之一。

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
