SMCJ36CA 双向瞬态抑制二极管(TVS)产品概述

SMCJ36CA是台湾迪嘉(TWGMC)推出的一款工业级双向瞬态抑制二极管(TVS),核心作用是快速钳位电路中的瞬态过压,保护敏感电子元件免受雷击、开关浪涌、静电放电(ESD)等干扰损坏。其紧凑封装、宽温耐受与稳定电气特性,使其广泛适配通信、工业控制、消费电子及汽车电子等场景。

一、产品定位与典型应用场景

SMCJ36CA属于中等功率TVS器件,聚焦中低压电路的瞬态过压防护,典型应用包括:

  1. 通信设备:路由器、交换机、基站的电源端口与高速信号接口(以太网、USB)的浪涌防护;
  2. 工业控制系统:PLC输入输出模块、传感器接口、电机驱动电路的瞬态干扰抑制;
  3. 消费电子:手机充电器、显示器电源回路、机顶盒的静电与浪涌防护;
  4. 汽车电子:车载12V系统(传感器线路、电源接口)的宽温环境防护(符合-55℃~+150℃要求)。

二、核心电气参数详解

SMCJ36CA的电气参数经严格测试,关键指标明确:

  1. 极性与截止电压:双向设计,无需区分正负极即可抑制正负瞬态过压;反向截止电压(Vrwm)=36V,即正常工作时器件允许的最大反向电压,电路电压需低于此值避免导通。
  2. 击穿与钳位特性:击穿电压(Vbr)典型值44.2V(器件导通阈值);钳位电压(Vc)典型值58.1V(脉冲电流下的最大端电压),直接决定被保护元件的安全电压上限。
  3. 脉冲耐受能力:峰值脉冲功率(Ppp)=1.5kW(测试波形10/1000μs,即上升10μs、半峰值1000μs);峰值脉冲电流(Ipp)=25.9A(同波形),可耐受中等能量浪涌。
  4. 反向漏电流:Ir=1μA(@Vrwm=36V),正常工作时漏电流极小,对电路功耗无明显影响。

三、封装与机械特性

采用SMC封装(DO-214AB),表面贴装设计适配高密度PCB:

  1. 尺寸紧凑:约3.2mm×2.7mm×1.6mm,节省电路板空间;
  2. 工艺兼容:引脚镀锡处理,支持回流焊、波峰焊等自动化生产;
  3. 机械强度:环氧树脂封装,绝缘性与抗冲击能力优异,可承受常规生产应力。

四、可靠性与环境适应性

SMCJ36CA满足工业级可靠性要求:

  1. 宽温工作:-55℃~+150℃,覆盖低温户外、高温车间等极端场景;
  2. 浪涌循环:多次冲击后关键参数(Vbr、Vc)变化极小,长期稳定;
  3. 环保合规:符合RoHS无铅标准,不含有害物质。

五、应用设计注意事项

为确保防护效果,需注意:

  1. 近保护端安装:减少引线电感(避免过压峰值升高),提升钳位效率;
  2. 电压匹配:电路工作电压需低于Vrwm(36V),近36V时建议降额至80%(≤28.8V);
  3. 散热设计:脉冲功率大时,增加PCB焊盘散热面积(如连接铜箔);
  4. 并联扩展:需更高浪涌耐受时,可并联多个器件(保证参数一致性)。

SMCJ36CA凭借双向防护、宽温工作与紧凑封装,成为中低压电路瞬态保护的高性价比选择,适配对可靠性与成本均有要求的工业及消费电子应用。

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
