SMBJ15A 单向瞬态抑制二极管(TVS)产品概述

一、核心技术参数与规格说明

SMBJ15A是一款针对静电(ESD)和浪涌干扰设计的单向瞬态抑制二极管,核心参数明确支撑其保护性能:

  • 极性:单向(仅对特定方向的脉冲起抑制作用,需匹配电路极性);
  • 反向截止电压(Vrwm):15V(系统正常工作时可承受的最大反向电压,建议电路工作电压低于此值);
  • 钳位电压:24.4V(遭遇峰值脉冲时,将电压钳位在安全范围,避免后级芯片被击穿);
  • 峰值脉冲电流(Ipp):24A(8/20μs标准脉冲波形下的最大耐受电流,体现浪涌冲击能力);
  • 峰值脉冲功率(Ppp):600W(对应脉冲电流的功率容量,满足多数中等强度浪涌需求);
  • 击穿电压:16.7V(反向电压达到此值时开始导通,启动保护机制);
  • 反向漏电流(Ir):5μA(反向截止时的漏电流,低功耗设计减少系统静态损耗);
  • 工作温度范围:-55℃~+150℃(结温Tj下的宽温范围,适应极端环境如工业、汽车场景);
  • 类型:TVS(瞬态抑制二极管,兼具ESD和浪涌双重保护功能)。

二、封装形式与品牌背景

  • 封装:SMB(DO-214AA)表面贴装封装,体积小巧(约2.7×1.7×1.0mm),兼容自动贴装设备,适合高密度PCB设计,广泛应用于小型化电子设备;
  • 品牌:GOODWORK(固得沃克),国内专注于保护器件的制造商,产品覆盖TVS、ESD、压敏电阻等,以高可靠性、高性价比著称,SMBJ系列是其经典浪涌保护产品线,已通过多项行业认证。

三、典型应用场景

SMBJ15A的参数特性使其适配多种需要双重保护的场景:

  1. 消费电子:智能手机、平板电脑、蓝牙耳机等便携设备的USB/Type-C接口、充电电路,抑制静电放电(如人体接触)和电源浪涌;
  2. 工业控制:PLC、传感器、工业电源模块的输入输出端,宽温范围适应车间-40℃~+85℃的环境变化;
  3. 汽车电子:车载充电器、显示屏、胎压监测传感器的保护电路,满足汽车级-40℃~+125℃的温度要求;
  4. 通信设备:路由器、交换机、光模块的信号/电源端口,抑制雷电感应浪涌和静电干扰。

四、产品优势与应用价值

  1. 双保护集成:同时实现ESD(静电)和浪涌保护,无需额外配置两种器件,简化电路设计,降低PCB空间占用;
  2. 高可靠性:低反向漏电流(5μA)减少系统静态功耗,宽温范围(-55℃~+150℃)适应极端工况,600W峰值功率满足多数场景的浪涌需求;
  3. 小型化适配:SMB封装符合电子设备轻薄化趋势,适合便携设备、小型模块的高密度设计;
  4. 成本效益:固得沃克的SMBJ系列性价比突出,在保证性能的前提下降低系统BOM成本,适合量产应用。

五、选型与使用注意事项

  1. 极性匹配:单向TVS需注意电路极性,反向截止电压端应接系统正电压端,接反会导致保护失效;
  2. 电压适配:系统正常工作电压需低于15V(反向截止电压),避免TVS在正常工作时导通;
  3. 脉冲容量:若应用场景浪涌强度超过600W,需并联器件或选择更高功率型号;
  4. 焊接规范:SMB封装为表面贴装,焊接温度需控制在260℃以内(持续时间≤10s),避免过热损坏器件。

SMBJ15A作为一款高性价比的单向TVS器件,在静电和浪涌保护领域具有广泛应用前景,可有效提升电子设备的抗干扰能力和可靠性,适合消费电子、工业、汽车等多领域的保护需求。

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
