KSMAJ6.5CA-E3/61 TVS瞬态抑制二极管产品概述

一、产品核心定位与典型应用场景

KSMAJ6.5CA-E3/61是一款双向瞬态抑制二极管(TVS),专为电子电路的瞬态过压防护设计,可有效抑制静电放电(ESD)、开关浪涌、雷击浪涌等突发高压,避免MCU、传感器、通信芯片等敏感元器件被损坏。其典型应用覆盖以下领域:

  • 消费电子:智能手机、平板电脑、智能穿戴的USB端口、音频接口、电源输入保护;
  • 工业控制:PLC模块、传感器节点、电机驱动电路的宽温环境防护;
  • 通信设备:路由器、交换机、基站射频接口的浪涌抑制;
  • 车载辅助:车载USB充电口、低功耗传感器电路的瞬态保护(适配-55℃~+150℃宽温)。

二、关键电气参数及技术意义

产品核心参数直接决定保护性能,各参数的实际价值如下:

1. 极性与基础电压参数

  • 双向极性:无需区分正负方向,安装时无需极性匹配,简化生产流程,避免接反失效;
  • 反向截止电压(Vrwm=6.5V):电路正常工作时TVS保持截止的最大电压(如5V系统下完全不导通,不影响电路功能);
  • 击穿电压(Vbr=7.22V):TVS从截止转为导通的临界电压,比Vrwm高0.72V,确保正常工作无漏电流干扰,过压时快速响应。

2. 保护能力参数

  • 钳位电压(Vc=11.2V):浪涌到达时,TVS将电路电压钳位在11.2V以下(若后端芯片最大耐压12V,可直接保障芯片安全);
  • 峰值脉冲电流(Ipp=35.7A):TVS能承受的最大峰值浪涌电流(10/1000μs标准波形),超过此值可能被击穿;
  • 峰值脉冲功率(Ppp=400W):可吸收的最大脉冲功率(≈Vc×Ipp),满足大多数中功率浪涌场景(如电源开关浪涌、小型雷击)。

3. 可靠性参数

  • 反向漏电流(Ir=500μA):Vrwm下的最小漏电流,不影响电路功耗,保证能效;
  • 工作温度(-55℃~+150℃):宽温设计,适配工业高温车间、低温户外设备等极端环境。

三、封装特性与可靠性

采用SMA(DO-214AC)表面贴装封装,具备以下优势:

  1. 小型化:尺寸仅2.7mm×1.6mm×1.1mm,适配高密度PCB设计(如智能手机主板);
  2. 焊接兼容:支持回流焊、波峰焊,焊接峰值温度≤260℃(持续10秒内),符合行业标准;
  3. 抗恶劣环境:封装结构抗机械应力,通过温度循环、振动测试,符合IEC 61000-4-2(ESD)、IEC 61000-4-5(浪涌)国际标准。

四、选型与使用注意事项

为确保保护效果,需注意以下要点:

  1. 选型匹配:Vrwm需大于电路正常电压(如5V系统选6.5V),钳位电压需小于后端芯片耐压;
  2. 安装位置:并联在被保护电路两端,尽量靠近保护点(如电源输入端、信号接口),减少线路阻抗影响;
  3. 焊接规范:避免高温长时间焊接,防止封装损坏;双向无需极性,但需确认并联连接正确;
  4. 降额使用:高浪涌频率场景(如频繁开关),建议Ipp降额至80%,延长寿命;
  5. 失效判断:若TVS短路(漏电流异常增大)或开路,需及时更换,避免失去保护。

该产品平衡了小型化、宽温可靠性与中功率浪涌防护能力,是消费电子、工业控制等领域过压保护的高性价比选择。

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
