SMAJ6.0CA 瞬态抑制二极管(TVS)产品概述

一、产品定位与核心功能

SMAJ6.0CA是静芯微(ElecSuper)推出的双向瞬态抑制二极管(TVS),核心作用是快速抑制电路中的瞬态过压(如静电放电ESD、电快速瞬变EFT等),保护敏感电子元器件免受损坏。其小体积SMA封装与宽温特性,使其成为消费电子、工业控制等领域接口防护的高性价比选择,尤其适合工作电压≤6V的电路系统。

二、关键电气参数详细解析

1. 极性与截止电压

采用双向导通设计,无需区分正负极,安装更便捷;反向截止电压(Vrwm)=6V,即电路正常工作电压≤6V时,TVS处于截止状态,不影响电路静态功耗与信号传输。

2. 钳位与击穿特性

击穿电压(Vbr)典型值为6.67V,当电路电压超过此阈值时,TVS快速击穿并导通;峰值脉冲下钳位电压(Vc)=10.3V,可将过压稳定在安全范围(如保护5V芯片时,10.3V远低于芯片最大耐压值,避免后端器件损坏)。

3. 脉冲防护能力

峰值脉冲电流(Ipp)=38.8A,峰值脉冲功率(Ppp)=400W,可承受IEC 61000-4-2标准下的高强度静电放电(如8kV接触放电、15kV空气放电),以及电机启停、雷击感应等瞬态干扰,防护能力满足多数工业与消费场景需求。

4. 反向漏电流

正常工作时反向漏电流(Ir)=400uA(典型值),漏电流小,不会增加电路静态功耗,适合低功耗设备(如蓝牙耳机、智能手环)应用。

三、封装与环境适应性

1. 封装规格

采用DO-214AC(SMA)贴片封装,尺寸小巧(约2.54mm×1.55mm×1.1mm),兼容标准贴片生产线,可直接贴装于PCB板,节省空间,适合高密度布局的设备(如智能手机主板)。

2. 宽温工作范围

工作温度覆盖**-65℃至+150℃**,满足工业级、车载级(若符合相关认证)等恶劣环境需求,可在高低温交替、湿度变化大的场景下稳定工作(如户外传感器、车载电子模块)。

3. 标准符合性

防护等级符合IEC 61000-4-2静电放电标准,确保产品在静电防护场景下的可靠性,可通过第三方静电测试验证。

四、典型应用场景

1. 消费电子接口防护

手机、平板、蓝牙耳机等设备的USB Type-C、充电接口,以及音频接口的静电与过压防护,避免用户插拔时的静电损坏(如充电时误触静电导致主板故障)。

2. 工业控制模块防护

PLC(可编程逻辑控制器)、传感器模块的信号输入输出端,防止现场电磁干扰(如电机启停产生的瞬态脉冲)损坏敏感电路(如ADC采样芯片)。

3. 通信设备接口防护

路由器、交换机的以太网接口、光纤收发器的信号端,抑制通信线路中的瞬态过压,保障数据传输稳定(如避免雷电感应损坏网络芯片)。

4. 车载电子辅助防护

车载USB接口、胎压监测传感器、倒车雷达等模块的瞬态防护(宽温特性支持车载环境,需结合车载认证使用)。

五、使用注意事项

1. 焊接规范

采用回流焊时,需遵循SMA封装的焊接温度曲线(如峰值温度≤260℃,焊接时间≤30秒),避免过热损坏器件;手工焊接建议使用恒温烙铁(≤350℃,焊接时间≤5秒)。

2. 降额使用建议

若工作环境温度接近150℃,或脉冲频率较高(如>10Hz),建议将Vrwm降额至5.5V以下,确保长期可靠性。

3. 并联防护扩展

如需更高防护电流(如超过40A),可采用2个SMAJ6.0CA并联(注意封装对齐,避免电流不均),提升总防护能力。

4. 安装位置

应尽可能靠近被保护器件的接口端,缩短TVS与被保护电路的距离(≤5mm),减少寄生电感影响,提升防护效率。

SMAJ6.0CA凭借双向防护、小体积、宽温特性,成为低电压电路瞬态防护的可靠选择,可覆盖多数消费电子与工业场景的防护需求。

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.
