ESDSLC3V3D3BS TVS管产品概述

ESDSLC3V3D3BS是扬杰科技(YANGJIE)推出的一款双向瞬态抑制二极管(TVS),专为3.3V供电系统的静电放电(ESD)和浪涌过压防护设计,兼具小封装、低电容、宽温适应性等特点,适配消费电子、通信、工业控制等多领域的高密度电路需求。

一、产品定位与核心功能

作为针对低电压系统的防护器件,ESDSLC3V3D3BS的核心功能是快速钳位瞬态过压,有效抑制静电放电(ESD)和浪涌脉冲对后端敏感电路(如MCU、传感器、通信接口等)的损坏。其双向极性设计适配I/O口双向信号传输场景,无需区分正负极,简化电路设计与焊接工艺。

二、关键电气参数解析

该器件的电气参数针对3.3V系统优化,核心指标如下:

1. 电压防护范围

  • 反向截止电压(Vrwm):3.3V,精准匹配主流3.3V供电电路的正常工作电压,确保无额外压降损耗;
  • 击穿电压(Vbr):典型值8V,保证过压触发的及时性;
  • 钳位电压(Vc):峰值11V,当遭遇瞬态过压时,快速将电压钳位在11V以内,保护后端器件不被击穿。

2. 脉冲防护能力

  • 峰值脉冲电流(Ipp):7A@8/20μs波形,满足IEC 61000-4-5浪涌防护标准(如1.2/50μs+8/20μs组合脉冲);
  • 峰值脉冲功率(Ppp):77W,可承受常见的浪涌冲击(如电源线上的雷击感应、开关瞬态)。

3. 低损耗特性

  • 反向漏电流(Ir):仅50nA(@Vrwm),对正常工作电路无额外功耗影响,适合低功耗设备;
  • 结电容(Cj):0.8pF,远低于普通TVS管(通常>1pF),适配USB2.0、SPI、I2C等高速信号线路,避免信号失真。

4. 温度适应性

工作温度范围为**-40℃~+85℃**,覆盖工业级和消费电子的宽温需求,在极端环境下仍能稳定防护。

三、封装特性与应用场景

1. 封装优势

采用SOD-323小型表面贴装封装,尺寸约1.6mm×0.8mm×0.6mm,体积仅为常规0805封装的1/3左右,适合智能手机、可穿戴设备、IoT终端等高密度PCB设计,有效节省布局空间。

2. 典型应用场景

  • 消费电子终端:智能手机/平板的USB接口、耳机接口、充电端口防护;
  • 通信接口:路由器、交换机的RJ45接口、WiFi模块的I/O口防护;
  • 工业控制:PLC的数字输入输出(DI/DO)口、传感器模块防护;
  • 可穿戴与IoT:智能手表、蓝牙模块、温湿度传感器的信号/电源线路防护。

四、可靠性与标准认证

ESDSLC3V3D3BS通过多项可靠性测试与国际标准认证:

  • 防护标准:符合IEC 61000-4-2(ESD防护) 和 IEC 61000-4-5(浪涌防护),可应对±8kV接触放电、±15kV空气放电等常见ESD冲击;
  • 可靠性测试:通过温度循环(-40+85℃,1000次)、湿度测试(85℃/85%RH,1000h)、振动测试(202000Hz,1g)等,确保长期稳定工作;
  • 品牌保障:扬杰科技作为国内功率半导体龙头,器件一致性与可靠性经市场验证。

五、产品优势总结

ESDSLC3V3D3BS的核心优势可概括为“小、快、稳、省”:

  • 小:SOD-323小封装,适配高密度设计;
  • 快:ns级过压响应,瞬间钳位;
  • 稳:宽温范围、低漏电流,工作稳定;
  • 省:低电容适配高速信号,无额外功耗损耗。

该器件是3.3V系统ESD/浪涌防护的高性价比选择,尤其适合对体积、功耗、信号完整性要求较高的小型化电子设备。

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
