Brightking(君耀)SMBJ13A/TR13 TVS二极管产品概述

SMBJ13A/TR13是台湾君耀(Brightking)推出的单向瞬态抑制二极管(TVS),专为电子电路的瞬态过压防护设计,凭借紧凑的SMB封装、宽温适应性及可靠的脉冲功率能力,广泛应用于通信、工业控制、汽车电子等领域。

一、产品定位与核心功能

SMBJ13A/TR13的核心定位是电路过压保护器件,可快速响应(ns级)雷击、静电放电(ESD)、电源浪涌等瞬态脉冲干扰,将瞬态电压钳位在安全范围内,避免后端敏感电子元件(如MCU、传感器、通信芯片等)因过压损坏。其单向导通特性(仅反向击穿保护)适合多数直流电路的单方向过压防护场景。

二、关键电气参数详解

该器件的核心电气参数直接决定防护能力,关键指标如下:

  1. 反向截止电压(Vrwm):13V
    正常工作时反向可承受的最大直流电压,电路工作电压需低于此值(如12V电源系统适配性强)。
  2. 击穿电压(Vbr):14.4V
    反向击穿的典型起始电压,处于Vrwm与钳位电压之间,是器件从截止到导通的过渡点。
  3. 钳位电压(Vc):21.5V(@Ipp=28A)
    当瞬态脉冲电流达到28A时,器件将电压钳位至21.5V以内,此值需小于后端元件的最大耐受电压(如多数芯片的过压阈值≥24V)。
  4. 峰值脉冲电流(Ipp):28A(10/1000μs波形)
    标准浪涌波形下可承受的最大峰值电流,对应典型雷击或电源浪涌的脉冲强度。
  5. 峰值脉冲功率(Ppp):600W
    由Vc与Ipp乘积(21.5V×28A≈602W)决定,是器件的脉冲功率防护能力上限。
  6. 反向漏电流(Ir):1μA(@Vrwm)
    正常工作时反向漏电流极小,不影响电路功耗与稳定性。

三、封装与物理特性

SMBJ13A/TR13采用SMB封装(DO-214AA),属于表面贴装型封装,具备以下特点:

  • 尺寸紧凑:典型尺寸为2.0mm(长)×3.5mm(宽)×1.5mm(高),适合高密度PCB设计(如小型化通信模块);
  • 极性标识清晰:封装侧面有色环标识反向端,便于焊接时极性判断;
  • 机械可靠性:SMB封装抗振动、冲击性能优异,可满足户外设备或车载环境的机械应力要求。

四、环境适应性

该器件的环境适应性覆盖宽温与恶劣工况:

  • 工作温度范围:-65℃+150℃,支持工业级(-40℃+85℃)、汽车级(-40℃~+125℃)及极端低温场景;
  • 存储温度:-65℃~+175℃,满足长期存储的温度要求;
  • 耐温稳定性:封装材料与芯片工艺支持高温下的持续工作,无性能衰减。

五、典型应用场景

SMBJ13A/TR13的参数特性使其适配多种过压防护场景:

  1. 通信设备:路由器、交换机、光模块的电源端口、以太网接口过压保护;
  2. 工业控制:PLC模块、传感器节点、伺服驱动器的输入输出端防护;
  3. 汽车电子:车载充电器、信息娱乐系统辅助电源的浪涌防护(需结合车规认证);
  4. 消费电子:高端智能设备(如户外监测仪)的电源与信号端口防护;
  5. 电源系统:DC-DC转换器、开关电源的输入浪涌抑制。

六、选型与使用注意事项

  1. 选型匹配:
    • Vrwm需≥电路正常工作电压(如12V系统选13V适配);
    • Vc需≤后端元件的最大耐受电压(如芯片过压阈值24V时,21.5V满足);
  2. 极性确认:
    单向TVS的反向端需接电路高电位侧(如电源正极→TVS反向端→GND),避免接反失效;
  3. 焊接规范:
    回流焊峰值温度≤260℃,持续时间≤10秒;手工焊接温度≤350℃,时间≤3秒,避免过温损坏;
  4. 并联扩容:
    若需更高脉冲功率,可并联多个同型号器件(需保证器件一致性,避免电流不均)。

综上,SMBJ13A/TR13凭借可靠的防护性能、宽温适应性与紧凑封装,成为中低压直流电路过压防护的高性价比选择,适用于对空间与可靠性要求较高的电子设备。

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.
