SMAJ16A/TR13 产品概述

一、产品简介

SMAJ16A/TR13 是台湾君耀(Brightking)出品的一款单向瞬态电压抑制器(TVS),封装为常用的SMA(DO-214AC)。器件针对线路瞬态过电压和浪涌脉冲提供快速钳位保护,适用于汽车电子、通信设备、电源输入端以及一般工业控制场合的过压防护。产品以高能量吸收能力与宽工作温度范围著称,适合苛刻环境下的可靠保护需求。

二、主要电气参数

  • 反向工作电压 Vrwm:16 V(反向稳压工作点)
  • 击穿电压 Vbr:19.7 V(典型)
  • 钳位电压 Vc:26 V(在10/1000 μs,Ipp条件下)
  • 峰值脉冲电流 Ipp:15.4 A(标准10/1000 μs波形)
  • 峰值脉冲功率 Ppp:400 W(10/1000 μs)
  • 反向漏电流 Ir:1 μA(在 Vrwm 条件下,常温测量)
  • 工作温度范围:-65 ℃ ~ +150 ℃
  • 极性:单向(对于正向瞬态进行钳位,负极接地)

三、封装与机械特性

SMA(DO-214AC)封装,体积小、焊接可靠,便于自动贴装与回流焊工艺。后缀/TR13 表示卷装(Tape & Reel)包装,适合SMT大批量生产。推荐焊盘尺寸和散热铜箔按厂商样本设计,以保证最佳热散及焊接可靠性。

四、应用场景

  • 通信基站、路由器和光纤收发模块的输入/输出端保护
  • 电源输入与开关电源(SMPS)初级侧的浪涌防护
  • 汽车电子(耐热等级高,适用于车载附件和控制模块)
  • 工业控制、PLC 和楼宇自控系统中对雷击/开关瞬变的防护

五、设计要点与使用建议

  • 布局:TVS 应尽量靠近被保护的引脚或接口放置,走线短且宽,以降低串联电感和提升钳位效率。
  • 极性:单向器件应确认正负极方向,正向对地钳位;错误安装会影响保护能力或引起损坏。
  • 热管理:高能量脉冲后器件温升明显,应保证焊盘和PCB铜箔有适当散热面积,避免重复大脉冲造成热失效。
  • 额定使用:TVS 适合吸收脉冲能量,不宜长期在高于 Vrwm 的电压下工作;对连续过压或短路需配合限流器件(熔断器、限流电阻)使用。
  • 可靠性考量:在高湿、高温或有振动的环境中,建议参照厂家可靠性测试报告(如热循环、冲击、ESD)进行选型验证。

六、优点与限制

优点包括高峰值功率吸收(400 W@10/1000 μs)、低反向漏电和宽温度工作范围(-65~150 ℃),适合高能量浪涌场合。限制在于钳位电压相对固定(26 V),对要求更低钳位电压或更高脉冲电流的场合需选择更高规格的TVS或并联/组合方案。

七、结论与选型建议

SMAJ16A/TR13 适合用于对16 V 级别直流线或信号线进行高能量瞬态保护的场合,尤其在要求体积小、可回流焊和耐高温的工业或车载项目中表现优良。选型时请核对系统最大承受电压、允许钳位电压及脉冲能量需求,并结合PCB 布局与散热条件进行共同验证。如需更高浪涌电流或更低钳位值,可联系供应商获取系列其它型号对比建议。

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
