PESD15VS2UT-N TVS二极管产品概述

一、产品定位与核心价值

PESD15VS2UT-N是伯恩半导体(BORN)推出的单向ESD防护TVS二极管,专为电子设备的静电放电(ESD)、电快速瞬变脉冲群(EFT)及浪涌干扰防护设计。其核心价值在于小体积封装、宽电压覆盖、多标准兼容,可有效保护敏感电子元件(如MCU、传感器、通信模块等)免受瞬态过压损坏,同时适配消费电子、工业控制、通信等多领域的小型化产品需求。

二、核心电气参数深度解析

该器件的关键参数针对实际防护场景做了优化,核心参数及意义如下:

1. 电压类参数

  • 反向截止电压(Vrwm=15V):正常工作状态下反向截止,不影响15V以下电路(如3.3V、5V系统)的信号传输;
  • 击穿电压(Vbr=17.6V):瞬态过压超过17.6V时触发雪崩击穿,快速导通泄放电流;
  • 钳位电压(Vc=35V):8/20μs标准浪涌波形下,10A脉冲电流通过时,器件两端电压被钳至35V以下,避免后端元件过压击穿。

2. 电流与功率参数

  • 峰值脉冲电流(Ipp=10A@8/20μs):可承受10A标准浪涌电流,覆盖雷电感应、开关浪涌等日常冲击;
  • 峰值脉冲功率(Ppp=350W):由钳位电压与脉冲电流乘积得出(35V×10A),反映瞬时功率耐受能力;
  • 反向漏电流(Ir=100nA):漏电流极小,不影响电路功耗及信号完整性。

3. 高频特性参数

  • 结电容(Cj=50pF):适配低速至中速信号接口(如UART、I2C、USB 2.0),无明显信号失真;若需高频RF应用,可搭配低结电容型号,但本型号已覆盖主流数字接口需求。

三、EMC防护能力与标准兼容

PESD15VS2UT-N通过三项核心EMC防护标准,满足产品认证需求:

  • IEC 61000-4-2(ESD防护):覆盖人体放电(接触±8kV、空气±15kV及以上等级),抵御日常静电冲击(如人体触摸、衣物摩擦);
  • IEC 61000-4-4(EFT防护):应对电源开关、继电器动作产生的快速脉冲群,避免设备误触发;
  • IEC 61000-4-5(浪涌防护):兼容1.2/50μs电压浪涌与8/20μs电流浪涌,抵御雷电感应、电网浪涌。

四、封装与可靠性设计

  • 封装形式:SOT23:超小型表面贴装(尺寸2.9×1.6×1.1mm),适配高密度PCB(如智能手机、可穿戴设备),安装便捷;
  • 可靠性设计:采用成熟TVS工艺,结电容一致性好,漏电流稳定,工作温度范围-55℃~150℃(工业级),满足恶劣环境需求。

五、典型应用场景

该器件因体积小、防护均衡,广泛应用于:

  1. 消费电子:智能手机USB/耳机孔、智能手表无线充电接口;
  2. 工业控制:PLC输入输出模块、RS485总线端口、工业传感器接口;
  3. 通信设备:路由器以太网端口、Wi-Fi模块接口;
  4. 汽车电子(辅助):车载USB接口、显示屏触摸端口(需结合汽车级认证)。

六、选型对比与应用建议

与同类15V单向ESD TVS相比,优势在于:

  • 小体积SOT23封装,比SOT-323节省30%PCB空间;
  • 10A脉冲电流能力,优于竞品5A/8A规格;
  • 伯恩半导体供货稳定,交期短。

应用建议:并联在被保护端口与地之间,靠近接口端安装,缩短信号路径提升防护效果。

该器件凭借均衡的防护能力与小型化设计,成为多领域电子设备瞬态防护的高性价比选择。

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
