SMCJ30CA-AT/TR13瞬态抑制二极管产品概述

SMCJ30CA-AT/TR13是台湾君耀(Brightking)推出的一款双向瞬态抑制二极管(TVS),专为低压电路的瞬态过压防护设计,凭借宽温范围、高脉冲耐受能力及小体积贴片封装,在消费电子、工业控制、汽车电子等领域具备广泛应用价值。

一、产品核心定位与设计目标

该产品的核心定位是低压电路的快速过压保护器件,针对电路中常见的静电放电(ESD)、雷击感应脉冲、开关瞬态过压等干扰,实现“快速响应、精准钳位、低功耗待机”的防护目标:

  • 正常工作时反向截止,不影响电路静态功耗;
  • 过压脉冲触发时快速导通(典型响应时间ns级),将电压钳位在安全范围;
  • 耐受多轮脉冲冲击后仍保持稳定性能,保障电路长期可靠性。

二、关键性能参数深度解析

SMCJ30CA-AT/TR13的参数设计精准匹配低压防护需求,核心参数可分为三类:

(一)保护特性参数

  1. 极性:双向
    可同时防护正、负向过压脉冲,无需区分电路正负极,简化设计与安装;
  2. 反向截止电压(Vrwm):30V
    电路正常工作时TVS反向截止的最大电压,适配12V~24V典型低压电路(如车载USB、工业传感器);
  3. 钳位电压(Vc):48.4V
    峰值脉冲电流(31A)下的电压钳位值,确保后级器件(如MCU、传感器)的工作电压不超过其耐压极限;
  4. 峰值脉冲电流(Ipp):31A
    单次8/20μs标准脉冲下的最大耐受电流,可应对较强瞬态干扰;
  5. 峰值脉冲功率(Ppp):1.5kW
    脉冲能量耐受能力,支持多轮脉冲冲击(如静电放电、频繁开关瞬态)。

(二)静态电气参数

  1. 击穿电压(Vbr):33.3V
    反向过压时的击穿导通电压,比Vrwm高10%左右,避免电路正常波动(如电压纹波)触发误导通;
  2. 反向漏电流(Ir):1μA
    反向截止时的漏电流,远低于常规电路功耗要求,不影响系统待机效率。

(三)环境与可靠性参数

  • 工作温度:-55℃~+150℃
    宽温范围覆盖工业级(-40℃+85℃)及汽车级(-40℃+125℃)需求,可在极端环境下稳定工作;
  • 封装:SMC(DO-214AB)
    表面贴装封装,尺寸紧凑(约2.0mm×3.8mm),适配高密度PCB设计,支持自动化贴装生产。

三、品牌与封装优势

(一)Brightking(君耀)品牌背书

作为台湾知名被动元器件厂商,君耀在TVS领域拥有成熟的设计与制造工艺,产品一致性好、可靠性高,广泛应用于国际一线品牌的消费电子、汽车电子产品中,符合RoHS等环保标准。

(二)SMC封装的应用价值

  1. 小体积: 相比传统插件封装,节省PCB空间,适配小型化产品(如智能手表、无线传感器节点);
  2. 高集成: 适合多通道防护设计(如USB接口、多传感器端口),可并行布置多颗器件;
  3. 易加工: 表面贴装工艺兼容主流SMT生产线,降低生产难度与成本。

四、典型应用场景

SMCJ30CA-AT/TR13的参数特性使其在多领域具备实用价值:

  1. 消费电子:智能手机/平板的充电接口、耳机接口ESD防护;无线耳机充电盒的过压保护;
  2. 工业控制:PLC输入输出端口、温度/压力传感器节点的瞬态过压防护;
  3. 汽车电子:车载USB接口、胎压监测模块、倒车雷达传感器的宽温环境防护;
  4. 通信设备:小型基站、路由器的以太网接口、SIM卡槽的过压保护。

五、选型与应用注意事项

  1. 参数匹配原则:
    选择时需确保Vrwm≥电路正常工作电压(如电路工作电压24V,选30V可留10%余量);钳位电压Vc需≤后级器件的最大耐压(如工业24V电路后级器件耐压50V,48.4V为安全范围);
  2. 安装注意事项:
    TVS需并联在被保护电路两端(正负极之间),布线尽量短(减少寄生电感影响),避免串联;
  3. 可靠性考量:
    宽温范围适合高低温环境,若应用于汽车电子需确认符合AEC-Q101标准(君耀该系列部分产品已通过认证)。

该产品凭借平衡的性能参数、可靠的品牌品质及灵活的封装设计,成为低压电路瞬态防护的高性价比选择,可满足不同领域的过压保护需求。

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
