SMAJ13CA(GOODWORK)产品概述

一、产品简介

SMAJ13CA 是 GOODWORK(固得沃克)推出的一款双向瞬态电压抑制器(TVS),封装为 DO-214AC(SMA)。器件用于吸收突发的静电放电(ESD)与浪涌能量,保护敏感电子电路免受过压损坏,适用于工业、电源、通信与消费类电子等多种场景。

二、主要电气参数

  • 极性:双向(Bidirectional),对称钳位正负方向均有效;
  • 反向截止电压 Vrwm:13 V;
  • 击穿电压 Vbr(典型):14.4 V;
  • 钳位电压 Vc(典型):21.5 V(对应峰值脉冲条件);
  • 峰值脉冲电流 Ipp:18.6 A;
  • 峰值脉冲功率 Ppp:400 W;
  • 反向电流 Ir:5 μA(常温条件);
  • 工作温度范围:-55 ℃ ~ +150 ℃(Tj);
  • 类型:TVS,封装:DO-214AC(SMA)。

三、产品特点与优势

  • 双向保护:适合交流或双向脉冲环境(例如通信对地、信号线和音频线路);
  • 高吸收能力:单脉冲峰值功率 400 W、峰值电流 18.6 A,能有效应对短时浪涌;
  • 低漏电流:典型 Ir = 5 μA,有利于节省待机功耗并保护高阻电路;
  • 宽工作温度:-55 ℃ 至 +150 ℃,适合严苛工业与汽车附近温度环境(需参照实际应用的相关认证)。

四、典型应用场景

  • 电源母线浪涌保护(DC 13V 级别系统的输入保护);
  • 通信接口与串口防护(RS-232/RS-485 等对称信号线);
  • 工业控制设备、仪表、安防与消费电子的过压保护;
  • 作为模块或板级器件,靠近进线/接口放置以吸收外来瞬态干扰。

五、选型与使用建议

  • 工作电压匹配:选用 Vrwm(13 V)应高于正常工作电压并低于被保护电路最大允许电压;
  • 钳位判定:钳位电压 21.5 V 为典型值,应确保被保护器件能承受该电压短时冲击;
  • 脉冲条件:Ipp 与 Ppp 通常基于标准脉冲波形(请结合厂家数据手册确认具体脉冲宽度与测试条件);
  • 布局建议:将 TVS 尽量靠近受保护端口或连接器焊盘放置,减小寄生电感;并配合熔断器或限流元件提升系统安全性;
  • 并联注意:若需更高能量吸收能力,使用并联器件前应考虑均流与热分布问题,优先参考厂家推荐方案。

六、封装与可靠性

DO-214AC(SMA)为通用贴片封装,便于波峰/回流焊安装,适合自动化生产。器件在高温范围内保持参数稳定,但在长时间反复大能量冲击下仍需关注热应力与焊接可靠性。

七、注意事项与测试建议

  • 在设计前获取并参考完整数据手册(包含钳位曲线、动态电阻、脉冲测试条件和能量吸收曲线);
  • 设计时验证典型钳位电压与被保护电路耐压极限的安全裕度;
  • 实际系统级测试建议按 IEC/ISO 或相关浪涌/ESD 标准进行(含不同幅值、极性与重复脉冲场景)。

SMAJ13CA 以其双向保护、高脉冲吸收能力与工业级温度范围,适合用作对称信号线与 13 V 级电源系统的短时浪涌与静电防护元件。选型时请结合完整规格书与实际系统要求进行验证。

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
