SENC23T3V2BC 双路ESD防护器件产品概述

SENC23T3V2BC是国内电子防护厂商静芯微(ElecSuper) 推出的一款双向双路ESD(静电放电)防护器件,专为敏感电子电路的瞬态过压防护设计,符合国际ESD防护标准IEC 61000-4-2,可有效抵御静电冲击对芯片、传感器等元件的损坏或误触发风险,适配多场景电子设备的小型化、高可靠性需求。

一、产品定位与核心功能

作为通用型ESD防护器件,SENC23T3V2BC的核心作用是:当电路遭遇静电放电(如人体接触、设备插拔产生的ESD脉冲)时,快速导通并钳位电压,将瞬态过压限制在后端器件的耐受范围内。其双路设计可同时防护两路独立信号,双向极性支持信号正反方向防护,无需额外匹配方向,简化电路布局。

二、关键电气参数解析

SENC23T3V2BC的参数经过优化,兼顾防护能力与电路兼容性:

1. 防护电压指标

  • 反向截止电压(Vrwm):3.3V:匹配主流3.3V供电电路的工作电压,正常工作时器件截止,不影响信号传输;
  • 击穿电压:4.5V:当电压超过4.5V(典型值)时,器件启动防护,快速导通泄放电流;
  • 钳位电压:12V:峰值脉冲下将电压钳位至12V以内,确保后端器件(如MCU、传感器)安全。

2. 脉冲耐受能力

  • 峰值脉冲电流(Ipp):30A:可承受单次30A ESD脉冲冲击,应对高强度静电;
  • 峰值脉冲功率(Ppp):300W@8/20us:基于国际标准8/20us浪涌波形测试,覆盖多数工业、消费电子场景需求。

3. 信号兼容性参数

  • 结电容(Cj):46pF:适合低速数字信号(UART、I2C)、音频信号,不损耗信号完整性;
  • 反向漏电流(Ir):1uA:正常工作时漏电流极小,不影响电路静态功耗与信号精度。

4. 通道与极性设计

  • 双路通道:单器件防护两路信号,减少元件数量,优化板级空间;
  • 双向极性:支持信号正反向传输防护,无需调整安装方向。

三、封装与可靠性特性

SENC23T3V2BC采用SOT-23封装,体积小巧(约2.9×1.6×1.1mm),适配便携式设备、IoT模块等高密度设计;同时具备优异可靠性:

  • 宽温范围:-55℃~+150℃:覆盖工业级(-40+85℃)与汽车级(-40+125℃)区间,可在恶劣环境稳定工作;
  • IEC 61000-4-2认证:符合国际静电放电抗扰度标准,防护有效性经权威验证。

四、典型应用场景

基于参数与封装优势,SENC23T3V2BC适用于:

  1. 工业控制:PLC、传感器接口的ESD防护;
  2. 消费电子:手机、平板的USB接口、耳机孔、按键电路防护;
  3. IoT节点:温湿度、位移传感器的信号输入防护;
  4. 汽车电子:车载显示屏、倒车雷达的静电防护(适配宽温环境)。

五、核心性能优势总结

SENC23T3V2BC在同类产品中具备差异化优势:

  • 宽温可靠性:-55~+150℃满足工业、汽车级严苛环境;
  • 强防护能力:30A脉冲电流+300W功率,抵御高强度ESD;
  • 双路双向:单器件防护两路信号,简化电路设计;
  • 低功耗兼容:1uA漏电流,不影响电路精度;
  • 小体积适配:SOT-23封装,适配小型化设备布局。

综上,SENC23T3V2BC是一款性能均衡、可靠性高的ESD防护器件,可广泛应用于消费电子、工业控制、汽车电子等领域,为敏感电路提供稳定静电防护。

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
