SMCJ36CA 瞬态抑制二极管(TVS)产品概述

晶导微电子推出的SMCJ36CA是一款双向瞬态抑制二极管(TVS),采用SMC(DO-214AB)贴片封装,专为中低压电子系统的瞬态过压防护设计,具备宽温适应性、低漏电流与高脉冲耐受能力,可有效抑制静电放电(ESD)、雷电感应及开关浪涌等瞬态干扰。

一、产品基本信息与核心定位

  • 品牌与型号:晶导微电子,SMCJ36CA
  • 封装类型:SMC(DO-214AB),贴片式表面贴装封装(典型尺寸2.2mm×3.2mm×1.6mm),适配自动化贴装产线,节省PCB布局空间。
  • 核心功能:双向过压防护,电路出现瞬态过压时快速导通钳位,将过压能量泄放至地,保护后端敏感元器件(如MCU、传感器、接口芯片)。
  • 通道特性:单通道双向设计,无需区分正负极,简化电路布线。

二、关键电性能参数解析

SMCJ36CA的参数围绕“防护有效性”与“系统兼容性”优化,核心指标如下:

1. 截止与击穿特性

  • 反向截止电压(Vrwm):36V,TVS正常工作时(反向偏置)可承受的最大直流电压,适配3.3V、5V、12V等中低压系统,确保TVS截止不影响电路运行。
  • 击穿电压(Vbr):44.2V(典型值),符合TVS“击穿电压为截止电压1.2倍左右”的特性,是TVS从截止到导通的临界电压,保证过压时快速响应。

2. 钳位与脉冲耐受能力

  • 钳位电压(Vc):58.1V(10/1000μs波形下),TVS导通后将过压钳位到的最大电压,需低于被保护器件耐压(如普通MCU耐压≥60V),确保后端器件安全。
  • 峰值脉冲电流(Ipp):25.9A(10/1000μs波形),峰值脉冲功率(Ppp):1.5kW(10/1000μs波形),两者匹配(Vc×Ipp≈1500W),可承受多次中等强度瞬态脉冲(如开关浪涌、小电流雷电感应)。

3. 漏电流与环境适应性

  • 反向漏电流(Ir):1μA(典型值),低漏电流避免TVS正常工作时额外功耗,适合电池供电的低功耗设备。
  • 工作温度范围:-55℃~+150℃,覆盖工业级与部分汽车级环境,可应用于户外设备、车载系统等 harsh 场景。

三、典型应用场景

SMCJ36CA的参数特性适配多类中低压系统防护,典型应用包括:

  1. 消费电子:手机、平板、笔记本的USB/HDMI接口、电源端口,抑制静电与充电浪涌。
  2. 工业控制:PLC输入输出模块、传感器节点、电机驱动电路,应对工业现场开关浪涌与电磁干扰。
  3. 汽车电子:车载娱乐系统(车机、音响)、车身传感器(温度/压力传感器),适配车载宽温环境。
  4. 通信设备:路由器、交换机、光模块的以太网/电源端口,抑制雷电感应与静电放电。

四、使用注意事项与选型参考

1. 选型匹配原则

  • Vrwm需大于系统最大工作电压(如12V系统选36V Vrwm,留足裕量);
  • 钳位电压Vc需低于被保护器件的最大耐压值(如MCU耐压60V,58.1V满足要求)。

2. 电路布线要求

  • 需并联在被保护电路两端(双向TVS不分正负极);
  • 尽量靠近被保护器件,减少引线长度(降低引线电感,避免过压尖峰)。

3. 替换参考

同参数竞品包括Vishay SMCJ36CA、Littelfuse 1.5KE36CA等,晶导SMCJ36CA性价比更高,适合成本敏感项目。

五、总结

晶导微电子SMCJ36CA作为高性价比双向TVS,以36V截止电压、58.1V钳位电压、1.5kW脉冲功率及宽温范围,为中低压系统提供可靠过压防护,适配消费电子、工业控制、汽车电子等多领域,是替代进口同类型器件的优质选择。

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
