SMAJ30CAQ 瞬态抑制二极管(TVS)产品概述

一、核心产品定位与基础信息

SMAJ30CAQ是扬杰科技(YANGJIE)推出的双向瞬态抑制二极管(TVS),属于SMAJ系列过压防护器件。其采用行业标准DO-214AC封装(即SMA封装),专为电子电路中的瞬态过压(如静电放电、雷击感应、开关浪涌等)防护设计,可有效隔离脉冲电压对后端敏感元器件(如IC、MOS管、传感器)的损坏风险。

二、关键电气参数详解

作为过压防护核心器件,SMAJ30CAQ的参数直接决定防护能力,关键参数及意义如下:

1. 电压等级与极性

  • 极性:双向(无正负极性要求,电路设计无需区分方向,简化布线);
  • 最大反向工作电压(Vrwm):30V(器件正常工作时可承受的最大反向直流电压,电路长期工作电压需低于此值);
  • 击穿电压(Vbr):典型值36.8V(反向击穿起始电压,实际应用需参考datasheet的范围规格);
  • 钳位电压(Vc):峰值脉冲下典型值48.4V(器件击穿后将电路电压钳位的目标值,限制后端过压应力)。

2. 脉冲耐受能力

  • 峰值脉冲电流(Ipp):8.3A(10/1000μs标准脉冲波形下的最大耐受电流);
  • 峰值脉冲功率(Ppp):400W(10/1000μs波形下的核心脉冲功率容量,反映强浪涌应对能力)。

3. 静态电气特性

  • 反向漏电流(Ir):典型值1μA(@Vrwm=30V)(漏电流极小,正常工作时几乎无额外功耗,不影响电路静态性能)。

三、封装特性与可靠性

SMAJ30CAQ采用DO-214AC(SMA)表面贴装封装,具备以下优势:

  1. 小型化设计:封装尺寸紧凑(行业标准SMA封装,长≈5.0mm、宽≈2.5mm),适配消费电子、通信设备等高密度PCB布局;
  2. 焊接兼容性:支持回流焊、波峰焊等常规表面贴装工艺,适配自动化生产流程;
  3. 可靠性保障:扬杰科技封装工艺经过温度循环、湿度老化等严格测试,可确保恶劣环境下长期稳定工作,应对脉冲冲击时封装完整性可靠。

四、典型应用场景

SMAJ30CAQ的30V电压等级及双向防护特性,使其广泛应用于以下领域:

  1. 消费电子:手机、平板、笔记本的USB接口、充电端口、耳机接口,防护静电放电(ESD)及开关浪涌;
  2. 通信设备:路由器、交换机、光模块的信号端口、电源输入,抑制雷击感应浪涌及静电干扰;
  3. 工业控制:PLC的I/O接口、传感器输入端口,保护敏感模拟电路免受工业环境浪涌冲击;
  4. 小型电源系统:12V/24V低电压电源输出端,防止负载切换或外部干扰导致的过压损坏。

五、产品应用优势总结

相较于同类器件,SMAJ30CAQ的核心优势包括:

  1. 双向防护简化设计:无需区分极性,降低PCB布线复杂度,避免极性接反风险;
  2. 低功耗无干扰:1μA漏电流确保正常工作时几乎无静态功耗,不影响电路效率;
  3. 参数明确易选型:400W脉冲功率、8.3A峰值电流等参数清晰,工程师可快速匹配电路需求;
  4. 性价比突出:扬杰科技作为国内知名厂商,产品质量可靠且成本可控,适合批量应用。

SMAJ30CAQ凭借双向防护、紧凑封装、可靠性能及明确参数,成为低电压电子电路过压防护的高性价比选择,广泛适配消费电子、通信、工业等多领域应用需求。

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
