扬杰ESD12VD3BA瞬态抑制二极管(TVS)产品概述

一、核心身份与基本定位

扬杰ESD12VD3BA是一款专为静电放电(ESD) 和瞬态浪涌防护设计的表面贴装TVS二极管,采用SOD-323(SC-90)超小型封装,主要用于保护低电压电子电路免受过压冲击。产品符合IEC 61000-4-2(ESD)、IEC 61000-4-5(浪涌)国际标准,适用于消费电子、通信终端等高密度集成场景,兼具高可靠性与成本优势。

二、关键电性能参数深度解析

1. 反向截止与钳位特性

  • 反向截止电压(Vrwm):12V
    正常工作时反向偏置的最大允许电压,确保电路静态下无导通损耗,适配12V及以下电源/信号电路。
  • 击穿电压(Vbr):典型值12.6V
    比Vrwm高5%左右,保证浪涌发生时快速导通(无明显延迟),避免后端器件因过压损坏。
  • 钳位电压(Vc):典型范围17V~22V
    随脉冲电流幅值变化(如24A@8/20μs时Vc≈22V),可有效限制过压峰值,将其控制在敏感器件的耐受范围内。

2. 静态损耗与信号兼容性

  • 反向漏电流(Ir):≤500nA(Vrwm下)
    静态功耗极低,不会影响电路正常工作电流,尤其适合低功耗设备(如智能穿戴)。
  • 结电容(Cj):135pF
    适配低频至中速信号(如USB2.0、UART、音频信号),但需注意:高频信号(>100MHz,如USB3.0)下电容耦合可能影响信号完整性,需换用低电容TVS。

3. 脉冲耐受能力

  • 峰值脉冲电流(Ipp):24A(8/20μs浪涌波形)
    可承受多次重复浪涌冲击,覆盖常见电源/信号端口的瞬态过流场景。
  • 峰值脉冲功率(Ppp):600W(8/20μs)
    满足大部分消费电子、通信设备的浪涌防护需求,无需额外并联多颗器件。

三、封装与可靠性设计

1. 超小型封装适配高密度布局

采用SOD-323(SC-90)封装,尺寸仅1.6mm×0.8mm×0.7mm(典型值),适合手机主板、智能手环等空间受限的PCB设计,支持自动贴装生产线高效生产。

2. 可靠性与标准合规

  • ESD防护能力:符合IEC 61000-4-2(接触放电±8kV、空气放电±15kV),可有效抵御人体静电冲击;
  • 浪涌防护能力:符合IEC 61000-4-5(1.2/50μs&8/20μs混合波形,2kV/100A),覆盖电网浪涌、雷电感应等场景;
  • 环保与工艺:无铅环保(RoHS compliant),采用扬杰成熟半导体工艺,产品一致性好,回流焊兼容性强。

四、典型应用场景

1. 消费电子终端

  • 手机、平板的USB接口、耳机接口、充电端口防护;
  • 智能穿戴设备(手环、手表)的充电/数据接口,防止静电和充电浪涌损坏内部芯片。

2. 通信与物联网设备

  • 路由器、交换机的以太网端口、WiFi模块接口;
  • 物联网传感器节点(温湿度、运动传感器)的信号输入端口,防护环境静电冲击。

3. 小型电子设备

  • 蓝牙音箱、耳机的电源和音频接口;
  • 便携式充电器的输出端口,防止输出过压损坏负载设备。

五、选型注意事项

  1. 信号速率匹配:避免用于高频信号(如USB3.0、HDMI2.0),需选择低电容TVS(<10pF);
  2. 电压匹配:电路正常工作电压需≤12V,否则反向漏电流会增大;
  3. 封装兼容性:需确认PCB焊盘设计适配SOD-323封装,避免贴装不良。

总结

扬杰ESD12VD3BA是一款高性价比的TVS防护器件,兼具小封装、低漏电流、强浪涌耐受能力等特点,符合国际防护标准,广泛适用于中低速信号和低电压电路的ESD/浪涌防护,是消费电子、通信终端等领域的理想选择。

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
