ESD36VD3B TVS管产品概述

一、产品核心定位与应用场景

ESD36VD3B是扬杰科技推出的双向瞬态抑制二极管(TVS),专为小型电子设备的ESD静电放电和浪涌过压防护设计,核心作用是在电路遭遇瞬态高压时快速导通,将电压钳位在安全范围内,保护后端敏感元器件(如MCU、传感器、通信芯片等)免受损坏。

该产品适配高密度、小型化电子设备,典型应用场景包括:

  • 消费电子:智能手机/平板的音频接口、USB Type-C接口防护;
  • 可穿戴设备:智能手表/手环的心率、加速度传感器输入接口;
  • IoT模块:低功耗通信模块(Wi-Fi、蓝牙)的天线接口、数据总线;
  • 小型家电:智能插座、遥控器的控制电路防护。

二、关键性能参数解析

ESD36VD3B的参数设计平衡了防护能力与电路兼容性,核心参数及实际意义如下:

1. 防护电压范围明确

  • 反向截止电压(Vrwm=36V):电路正常工作时TVS处于截止状态,无明显电流导通,不影响信号传输;
  • 击穿电压(Vbr=47V):当瞬态过压超过47V时,TVS快速击穿启动防护;
  • 钳位电压(Vc=76V):在5A峰值脉冲电流下,将过压钳位至76V以内,远低于后端器件耐压极限(多数半导体器件耐压≤100V),有效避免损坏。

2. 脉冲防护能力满足主流标准

  • 峰值脉冲电流(Ipp=5A@8/20us):可承受8/20us波形的5A浪涌电流(符合IEC 61000-4-5浪涌测试波形);
  • 峰值脉冲功率(Ppp=380W@8/20us):覆盖日常场景瞬态过压(如雷电感应、电源开关浪涌)的能量耐受需求。

3. 电气特性适配中低速信号

  • 反向漏电流(Ir=500nA):正常工作漏电流极小,不增加电路功耗或导致信号失真;
  • 结电容(Cj=13pF):适合UART、I2C等低速数字信号或音频模拟信号防护,对高速信号需结合场景评估;
  • 单路通道:针对单端信号防护设计,结构简单易布局。

三、封装与可靠性设计

ESD36VD3B采用SOD-323超小封装(尺寸约1.6mm×0.8mm×0.6mm),是小型化设备的优选封装:

  • 体积优势:大幅节省PCB空间,适配紧凑设备内部布局;
  • 工艺兼容:支持回流焊、波峰焊等常规贴片工艺,生产效率高;
  • 可靠性测试:经温度循环(-55℃~125℃)、湿度老化(85℃/85%RH)测试,确保恶劣环境下稳定防护。

四、典型应用电路与注意事项

ESD36VD3B的应用逻辑为并联在被防护信号/电源端与地之间,核心布局原则是靠近被防护器件(减少引线电感,提升防护响应速度),典型电路如下:

[信号输入端] → [可选限流电阻(10Ω~100Ω)] → [ESD36VD3B(信号→地)] → [后端敏感器件(如MCU引脚)]

应用注意事项:

  1. 电源防护需确认电源正常电压≤36V(避免TVS误导通);
  2. 多通道信号(如USB2.0 D+/D-)需每通道单独并联一颗;
  3. 禁止串联使用,需并联在信号/电源与地之间。

五、符合标准与认证

ESD36VD3B完全符合国际EMC标准,满足全球主流市场认证要求:

  • IEC 61000-4-2:静电放电防护,可承受接触放电±8kV、空气放电±15kV;
  • IEC 61000-4-5:浪涌防护,满足1.2/50us电压浪涌、8/20us电流浪涌测试;
  • RoHS认证:无铅、无镉等有害物质,符合欧盟环保指令。

六、产品优势总结

ESD36VD3B的核心优势可概括为**“小封装+强防护+低干扰”**:

  1. 超小SOD-323封装,适配高密度PCB;
  2. 双向防护,覆盖正负极性瞬态过压;
  3. 低漏电流、适中结电容,不影响电路正常工作;
  4. 满足主流EMC标准,可靠性有保障。

该产品是小型电子设备ESD/浪涌防护的高性价比选择,能有效提升设备抗干扰能力与使用寿命。

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.
