SMCJ75CA 双向瞬态抑制二极管(TVS)产品概述

一、产品定位与核心功能

SMCJ75CA是扬杰科技(YANGJIE)推出的双向瞬态抑制二极管(TVS),属于电路过压保护核心器件,主要针对突发瞬态脉冲干扰(如静电放电ESD、电快速瞬变脉冲群EFT、雷击浪涌等)提供快速防护。其核心作用是在微秒级时间内将电路电压钳位至安全范围,避免后端敏感元件(如IC、MOS管、传感器、通信模块等)因过压击穿损坏,保障电路稳定运行。

二、关键电气参数深度解析

SMCJ75CA的参数针对中等电压场景优化,各核心参数的实际意义如下:

  • 极性:双向
    无需区分正负极,正负脉冲均能有效防护,安装便捷,降低生产错误率。
  • 反向截止电压(Vrwm):75V
    电路稳态工作时,TVS保持截止状态的最大反向电压——即电路正常电压≤75V时,器件不介入电路,不影响信号传输与功耗。
  • 击穿电压:92.1V
    瞬态脉冲电压超过75V时,TVS开始击穿导通的阈值电压,是从“截止”到“钳位导通”的过渡点。
  • 钳位电压:121V
    导通后将电路电压稳定的最大值,确保后端元件承受电压不超过121V,避免过压损坏。
  • 峰值脉冲电流(Ipp):12.4A@10/1000us
    10/1000us为国际通用脉冲波形(前沿10μs、半峰值时间1000μs),器件能承受的最大峰值脉冲电流,超过该值可能导致性能下降。
  • 峰值脉冲功率(Ppp):1.5kW@10/1000us
    对应12.4A峰值电流与121V钳位电压的乘积(12.4×121≈1500W),反映TVS的瞬态浪涌耐受能力。
  • 反向漏电流(Ir):5μA
    75V截止电压下的漏电流,数值极小,不影响电路正常功耗与信号传输。

三、封装与物理特性

SMCJ75CA采用DO-214AB(SMC)表面贴装封装,适配多数应用场景的小型化需求:

  • 体积小巧:封装尺寸约2.54mm(宽)×5.08mm(长)×1.0mm(厚),适合高密度PCB设计,满足消费电子、工业控制等对小型化的要求;
  • 自动化兼容:表面贴装结构适配SMT自动化生产,提高生产效率;
  • 瞬态散热适配:虽为小封装,但TVS为瞬态工作(脉冲持续时间极短),其瞬态热阻可满足中等功率浪涌场景的散热需求。

四、典型应用场景

结合参数特性,SMCJ75CA适用于以下中等电压场景:

  1. 工业控制:PLC输入输出模块、4-20mA传感器接口、电机驱动电路的过压防护;
  2. 通信设备:以太网接口、WiFi/蓝牙/LoRa无线模块、基站射频电路的ESD/EFT防护;
  3. 消费电子:24V及以下电源适配器、智能家电控制板、便携式设备充电接口保护;
  4. 车载电子:12V/24V车载系统(显示屏、传感器)的浪涌抑制(符合ISO 7637车载标准)。

五、品牌与可靠性保障

SMCJ75CA由扬杰科技生产,其可靠性经过严格验证:

  • 合规性:符合RoHS环保标准,无铅无卤,适配全球市场要求;
  • 可靠性测试:通过1000次以上脉冲浪涌重复测试、-55℃~150℃温度循环测试、85℃/85%RH湿度测试,满足工业级应用要求;
  • 品质管控:全流程参数一致性管控,批量应用稳定性高,适合规模化生产需求。

SMCJ75CA凭借双向防护、中等电压适配、小体积封装等优势,成为工业、通信、消费电子等领域过压保护的高性价比选择。

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
