SMCJ90A/TR13 单向TVS二极管产品概述

一、产品基本定位与标识

SMCJ90A/TR13是台湾君耀(Brightking)推出的单向瞬态抑制二极管(TVS),属于SMCJ系列表面贴装器件,封装为SMC(DO-214AB)。型号各部分含义明确:

  • “SMCJ”:标识封装类型与系列(表面贴装TVS,适配自动化产线);
  • “90”:反向截止电压标称值(90V);
  • “A”:单向极性(仅抑制单方向过压);
  • “TR13”:编带包装的规格标识,方便批量贴装。

二、核心电性能参数解析

TVS的核心价值是纳秒级响应瞬态过压,将电压钳位到安全范围,SMCJ90A/TR13的关键参数需重点关注:

  1. 反向截止电压(Vrwm):90V
    电路正常工作时可承受的最大反向直流电压,未超此值时TVS截止,漏电流仅1μA,不影响电路静态功耗。
  2. 击穿电压(Vbr):100V
    瞬态电压超过此阈值时,TVS快速击穿导通,从截止态转入保护态,响应时间≤1ns(TVS典型特性)。
  3. 钳位电压(Vc):146V
    导通后限制的最高电压,是保护后级器件的核心指标——需确保IC、传感器等后级元件的最大耐受电压≥146V。
  4. 峰值脉冲电流(Ipp):10.3A
    标准8/20μs浪涌脉冲下的最大峰值电流,可承受单次或低重复频率脉冲(重复频率需参考规格书)。
  5. 峰值脉冲功率(Ppp):1.5kW
    脉冲持续时间内的最大功率容量,对应8/20μs脉冲的能量约12mJ,可覆盖常见开关浪涌、静电放电(ESD)场景。

三、封装与物理特性

采用SMC(DO-214AB)表面贴装封装,具备以下优势:

  • 尺寸紧凑:典型尺寸6.1mm×5.3mm×2.3mm,节省PCB空间,适配高密度电路设计;
  • 焊接可靠:扁平引脚设计,适配回流焊工艺,焊点强度高,耐机械振动;
  • 散热适配:封装热阻适中,中小功率浪涌场景无需额外散热片,大能量浪涌需结合PCB铜箔优化散热。

四、典型应用场景

SMCJ90A/TR13的电压等级与功率容量,使其广泛用于以下场景的过压保护:

  1. 工业控制:PLC输入输出端口、传感器接口、电机驱动电路,抵御雷击、开关浪涌;
  2. 通信设备:路由器、交换机、基站的电源/信号端口,抑制ESD与电网浪涌;
  3. 消费电子:机顶盒、智能家居控制器、显示器电源线路,保护内部IC免受瞬态冲击;
  4. 电力监测:电能表、数据采集模块信号端,避免电网波动损坏敏感电路。

五、选型与使用注意事项

  1. 电压匹配:电路正常工作电压需低于Vrwm(建议留10%-20%余量,如≤80V),避免TVS误触发;
  2. 钳位验证:确认后级器件最大耐受电压≥146V,确保保护有效性;
  3. 功率评估:根据电路浪涌能量(如雷击、负载切换),确认Ppp与Ipp满足需求;
  4. 极性选择:单向TVS适用于单方向过压(如电源正极→地),双向过压需选SMCJ90CA;
  5. 环保要求:产品符合RoHS无铅标准,适配绿色制造需求。

SMCJ90A/TR13凭借紧凑封装、可靠的瞬态保护能力,成为工业、通信等领域中小功率电路过压防护的常用选型。

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
