PESD12VS1UB 单向瞬态抑制二极管(TVS)产品概述

一、产品基本定位与核心属性

PESD12VS1UB是台舟电子(TECH PUBLIC) 推出的单向TVS二极管,专为电子设备的瞬态过压防护设计,核心定位是「小尺寸、低功耗、宽温适配」的高性价比防护器件。

核心属性包括:

  • 类型:单向瞬态抑制二极管(TVS);
  • 通道数:单路;
  • 封装:SOD-523(超小型表面贴装);
  • 工作温度:-55℃~+125℃(工业级宽温);
  • 防护标准:符合IEC 61000-4-2(ESD静电放电)、IEC 61000-4-4(EFT电快速瞬变脉冲群)。

二、关键电性能参数深度解析

1. 电压防护基础参数

  • 反向截止电压(Vrwm):12V
    器件正常工作时可承受的最大反向直流电压,此时处于截止状态,不干扰电路正常信号传输;
  • 击穿电压(Vbr):15V
    反向电压超过此值时,器件快速导通,启动过压防护(导通响应时间<1ns);
  • 钳位电压(Vc):19V/30V
    • 低功率瞬态(如ESD)下钳位电压约19V,确保后级电路电压安全;
    • 峰值脉冲功率150W(8/20us波形)时钳位电压30V,可吸收强浪涌能量。

2. 脉冲防护能力

  • 峰值脉冲功率(Ppp):150W@8/20us
    对应国际标准浪涌波形(电流波:8us上升/20us下降;电压波:1.2us上升/50us下降),可有效抵御常见瞬态干扰(如雷击感应、电源浪涌);
  • 反向漏电流(Ir):200nA
    远低于常规TVS的μA级漏电流,对电路静态功耗影响可忽略,适合低功耗设备。

3. 信号兼容性

  • 结电容(Cj):35pF
    在保证防护能力的同时,兼顾中等频率信号(如音频、低速数字信号)的传输质量,避免信号失真(不适合高频射频信号,但适配90%以上消费/工业接口)。

三、封装特性与机械可靠性

采用SOD-523超小型封装,尺寸仅1.6mm×0.8mm×0.6mm,适配高密度PCB设计(如手机、智能手环等便携设备);封装采用无铅工艺,符合RoHS环保要求,焊接可靠性高,可兼容回流焊、波峰焊等常规贴片工艺。

四、防护标准与环境适应性

1. 电磁兼容(EMC)防护

满足IEC 61000-4-2(ESD) 和 IEC 61000-4-4(EFT) 标准:

  • ESD防护:可抵御人体接触静电(典型8kV)、设备间耦合静电(空气放电15kV);
  • EFT防护:可承受4kV/5kHz的电快速瞬变脉冲群,避免设备误触发或损坏。

2. 宽温环境适配

工作温度覆盖-55℃+125℃,超出常规消费级器件(0℃70℃),可用于工业现场(如PLC接口)、车载辅助设备等严苛场景。

五、典型应用场景

  1. 便携式消费电子:手机、平板、蓝牙耳机、智能手环的USB/音频/充电接口防护;
  2. 工业控制设备:PLC输入输出口、传感器模块、RS485总线的过压防护;
  3. 通信终端:路由器、交换机的RJ45接口、无线AP的射频辅助防护;
  4. 物联网(IoT)节点:低功耗传感器、智能穿戴设备的内部电路防护。

总结

PESD12VS1UB通过「小尺寸封装+低功耗设计+宽温能力+可靠防护」的组合,成为消费电子、工业控制等领域瞬态过压防护的高性价比选择,尤其适合对尺寸、功耗敏感的场景,可有效降低设备因瞬态干扰导致的故障风险。

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
