KSMBJ6.8CA-E3/52 瞬态抑制二极管(TVS)产品概述

一、产品核心定位与功能

KSMBJ6.8CA-E3/52是KUU品牌推出的双向瞬态抑制二极管(TVS),专为电路中的瞬态过压防护设计,可快速响应浪涌脉冲(如静电放电、电源浪涌、雷击感应等),将电压钳位至安全范围,避免敏感电子元器件(如MCU、传感器、接口芯片)因过压击穿损坏。其双向极性无需区分正负极,简化电路布局;SMB(DO-214AA)贴片封装体积紧凑,适配高密度PCB设计,覆盖汽车、工业、消费电子等多领域应用。

二、关键电气参数及性能优势

1. 过压防护核心参数

  • 反向截止电压(Vrwm):6.8V
    对应电路常态工作电压的安全裕量,确保产品在电路正常运行时不导通,不影响信号传输或增加功耗。
  • 击穿电压(Vbr):7.22V(典型值)
    过压触发阈值,当电路电压超过该值时,TVS快速击穿导通,启动防护功能。
  • 钳位电压(Vc):11.2V(@Ipp=53.6A)
    浪涌脉冲峰值时的最大钳位电压,远低于多数敏感器件的耐压极限(如普通MCU耐压通常为15V),有效保护后级电路。

2. 脉冲耐受能力

  • 峰值脉冲功率(Ppp):600W
  • 峰值脉冲电流(Ipp):53.6A
    可承受常见浪涌脉冲(如IEC 61000-4-5标准下的2kV/1.2μs浪涌),满足多数应用场景的抗干扰需求。

3. 宽温可靠性

工作温度范围覆盖**-55℃~+150℃**,符合汽车电子(发动机舱高温、仪表盘低温)及工业级环境的温度要求,无需额外降额设计,长期稳定性强。

4. 低反向漏电流

反向电流(Ir)仅500μA(@Vrwm=6.8V),常态下漏电流极小,不会导致电路功耗增加或信号失真,适合低功耗应用(如便携式设备)。

三、封装与可靠性设计

  • SMB贴片封装:尺寸紧凑(约2.2×3.5mm),适配回流焊工艺,可实现自动化贴装,提高生产效率;引脚间距合理,焊接可靠性高,不易出现虚焊。
  • 品牌可靠性:KUU对该产品进行了严格的可靠性测试(如温度循环、脉冲寿命测试),确保在极端环境下性能稳定,故障率低。

四、典型应用场景

1. 汽车电子领域

  • 车载传感器(胎压监测、温度传感器)、ECU(电子控制单元)的过压防护;
  • 车载充电接口(Type-C、点烟器)的浪涌防护,应对汽车启动时的电压波动。

2. 工业控制领域

  • PLC(可编程逻辑控制器)输入输出端口、工业传感器模块的浪涌防护;
  • 伺服驱动器、变频器的接口保护,应对工业现场的电磁干扰。

3. 消费电子领域

  • 智能手机、平板电脑的充电端口、Type-C接口防护;
  • 音频设备(耳机、音箱)的静电放电(ESD)保护。

4. 通信设备领域

  • 路由器、交换机的以太网接口、光模块的浪涌防护,满足IEC 61000-4-5抗干扰标准。

五、选型与使用注意事项

  1. 参数匹配:反向截止电压需高于电路正常工作电压的10%-20%(如电路工作电压5V,6.8V可提供足够裕量);钳位电压需低于后级器件的最大耐压值。
  2. 焊接要求:采用回流焊工艺,焊接峰值温度不超过260℃(时间≤30秒),避免过温损坏。
  3. 并联扩容:若单颗功率不足,可多颗并联(需确保参数一致性),但需注意均流设计,避免局部过流。

该产品以高性价比、宽温可靠性及紧凑封装,成为多领域过压防护的优选器件,可有效提升电路的抗干扰能力与使用寿命。

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
