SMCJ85A/TR13 单向瞬态抑制二极管产品概述

SMCJ85A/TR13是台湾君耀电子(Brightking)推出的一款表面贴装单向瞬态抑制二极管(TVS),采用SMC(DO-214AB)封装,专为电路中的浪涌电压防护设计,可有效抑制雷击、静电放电(ESD)、电源瞬变等异常脉冲,保护敏感电子元器件免受损坏。

一、产品基本属性与品牌背景

SMCJ85A/TR13属于君耀经典TVS系列,核心定位为中低压电路的浪涌防护器件,关键属性如下:

  • 类型:单向TVS(仅反向击穿导通,正向无防护);
  • 品牌:Brightking(台湾君耀)——全球知名防护器件厂商,专注TVS、压敏电阻等产品研发,以高可靠性、宽温特性著称;
  • 封装:SMC(DO-214AB)——小型化表面贴装封装,适配自动化贴装工艺;
  • 标识:“85”代表反向截止电压等级,“A”表示单向导通。

二、关键电气参数解析

SMCJ85A/TR13的参数经过场景化优化,核心指标及实际意义如下:

  1. 反向截止电压(Vrwm):85V
    电路正常工作时的最大反向耐受电压——若电路工作电压≤85V,器件处于截止状态,几乎不影响电路运行。
  2. 钳位电压:137V
    浪涌触发时的电压限制值(11A峰值电流下)——将过压脉冲钳位在137V以内,避免后续元器件击穿。
  3. 峰值脉冲电流(Ipp):11A
    单次浪涌的最大耐受电流,可覆盖10/1000μs(雷击)、8/20μs(电源浪涌)等常见波形。
  4. 峰值脉冲功率(Ppp):1.5kW
    11A峰值电流对应的浪涌功率耐受能力,是判断防护强度的核心指标。
  5. 击穿电压:94.4V
    反向击穿的触发电压(略高于Vrwm),确保正常电压下不误触发,仅在浪涌时导通防护。
  6. 反向漏电流(Ir):1μA
    截止状态下的漏电流,数值极低——不增加电路功耗,避免误触发其他元件。

三、封装与典型应用场景

SMCJ85A/TR13采用SMC(DO-214AB)封装,尺寸约3.0mm×2.5mm×1.5mm,具备小体积、高密度贴装优势,典型应用场景包括:

  1. 消费电子:手机、平板、智能穿戴的充电接口、电源电路防护;
  2. 工业控制:PLC模块、传感器接口、电机驱动电路的浪涌抑制;
  3. 通信设备:路由器、交换机、光模块的信号端口及电源防护;
  4. 汽车电子(低电压场景):车载辅助电路、车载充电器的12V/24V系统防护(需确认汽车级认证适配性)。

四、核心性能优势

  1. 快速响应:ns级响应时间(远快于压敏电阻的μs级),可瞬间抑制ESD、雷击感应脉冲;
  2. 低功耗截止:1μA漏电流确保正常工作时几乎无功率损耗,不影响电路效率;
  3. 高防护能力:1.5kW峰值功率+11A峰值电流,覆盖多数中低压电路的浪涌风险;
  4. 小体积适配:SMC封装适合便携式设备、高密度电路板的空间限制;
  5. 高可靠性:君耀成熟工艺保障批量一致性,符合RoHS环保标准,工作温度范围-55℃~+150℃。

五、选型与使用注意事项

  1. 电压匹配:Vrwm需大于电路正常工作电压(如电路70V,选85V避免误触发);
  2. 极性确认:单向TVS阳极(带色环端)接低电位,阴极接被防护端;
  3. 焊接规范:无铅封装,回流焊温度≤260℃,避免高温损坏;
  4. 并联扩容:浪涌电流超单个Ipp时,可并联同型号器件(需注意均流);
  5. 场景适配:常规为工业级,汽车场景需确认是否符合AEC-Q认证(该型号未明确标注汽车级)。

SMCJ85A/TR13凭借小体积、高防护能力与稳定可靠性,成为中低压电路浪涌防护的经典选型,广泛适配各类电子设备的防护需求。

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
