CJSMAJ16CA 瞬态抑制二极管(TVS)产品概述

一、产品核心定位与类别属性

CJSMAJ16CA是江苏长电(CJ)推出的双向瞬态抑制二极管(TVS),属于SMAG封装系列的低压防护器件。其核心定位是为16V以下直流/交流电路提供快速、可靠的瞬态过压防护,可有效抑制静电放电(ESD)、雷电感应浪涌及电路开关瞬态脉冲,适配双向极性脉冲的防护需求(无需区分正负极)。

二、关键电气参数深度解析

该器件的电气参数针对低压防护场景做了精准优化,核心参数意义如下:

1. 直流工作参数

  • 最大反向工作电压(Vrwm):16V
    器件正常工作时允许施加的最大反向电压,在此电压下处于截止状态,保证电路正常供电不被干扰。
  • 反向漏电流(Ir):5μA
    施加Vrwm电压时的反向漏电流仅5μA,远低于常规TVS管水平,大幅降低对电路正常功耗的影响,适合低功耗设计。
  • 击穿电压(Vbr):19.69V
    反向击穿起始电压,比Vrwm高约23%,确保正常电压下不触发击穿,仅当电压超19.69V时快速导通防护。

2. 脉冲防护参数

  • 钳位电压(Vc):25.7V
    峰值脉冲导通后的最大电压,远低于后级敏感元器件耐压极限(通常≥30V),避免器件损坏。
  • 峰值脉冲电流(Ipp):15.4A@10/1000μs
    10μs前沿、1000μs半峰值浪涌波形下的最大耐受电流,体现大电流浪涌耐受能力。
  • 峰值脉冲功率(Ppp):400W@10/1000μs
    对应波形的峰值功率,覆盖大多数低压电路的浪涌防护需求。

三、封装与环境适应性设计

1. SMAG封装特性

SMAG为表面贴装封装(SMA小型化优化版),尺寸紧凑(长3.0mm×宽1.6mm×高1.1mm),适合高密度PCB设计,适配便携式设备、汽车电子模块等小型化终端。

2. 宽温工作范围

器件工作温度覆盖**-55℃+150℃**,满足工业级(-40℃+85℃)及汽车级(-40℃~+125℃)严苛环境,极端温度下稳定工作,无需额外散热。

3. 双向极性优势

双向导通设计,安装无需区分正负极,减少装配错误,提升生产效率,适配正负双向浪涌防护(如交流电路、双向信号接口)。

四、典型应用场景

CJSMAJ16CA的参数特性使其广泛适配以下场景:

  1. 低压直流电源防护:12V/16V车载电源、工业PLC电源、便携式设备(平板电脑、智能手环)电源端口;
  2. 通信接口防护:RS485、USB 2.0/3.0、CAN总线等接口的静电及浪涌防护;
  3. 工业控制电路:传感器输入输出、继电器线圈、电机驱动电路的瞬态过压防护;
  4. 汽车电子模块:车载中控、车灯控制、胎压监测等12V系统(符合汽车级温度要求)。

五、选型优势总结

相较于同类低压TVS管,CJSMAJ16CA具备以下核心优势:

  • 低功耗干扰:5μA反向漏电流,对电路正常工作影响极小;
  • 宽温可靠性:-55℃~+150℃覆盖工业/汽车级环境,长期稳定性强;
  • 安装便捷:双向极性无需正负极区分,降低装配成本;
  • 成本可控:CJ品牌量产优势,性价比高于进口同类器件;
  • 防护精准:Vrwm16V与Vc25.7V匹配度高,兼顾正常工作与过压抑制。

该器件通过了CJ内部可靠性测试(如高温老化、温度循环、机械振动等),可满足批量生产的一致性要求,是低压电路瞬态防护的高性价比选择。

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
