P6SMB6.8CA 产品概述

一、产品简介

P6SMB6.8CA 是华轩阳电子(HXY MOSFET)出品的一款双向 TVS 晶体管抑制器,封装为 SMB。该器件针对瞬态过压冲击提供高速、强力的钳位保护,峰值脉冲功率可达 600W,适用于工业、通信、汽车电子和消费电子中对稳压线和信号线的浪涌防护需求。

二、主要电气参数

  • 极性:双向(对称钳位正负极性冲击)
  • 反向截止电压 Vrwm:5.8 V(工作钳位电压前的稳态电压)
  • 击穿电压 Vbr:6.45 V ~ 7.14 V(典型击穿/雪崩范围)
  • 钳位电压 Vc:10.5 V(在规定脉冲电流下的峰值钳位)
  • 峰值脉冲电流 Ipp:58.1 A(对应标准冲击波形条件)
  • 峰值脉冲功率 Ppp:600 W(10/1000μs 标准测试条件下)
  • 反向电流 Ir:1 mA(在 Vrwm 条件下的泄漏电流)
  • 工作温度范围:-65 ℃ ~ +150 ℃
  • 封装:SMB,便于表面贴装与散热

三、工作原理与关键特性

P6SMB6.8CA 利用雪崩击穿特性在短时瞬变过电压出现时迅速导通,将能量吸收并钳制到安全电平(10.5 V 左右),保护后端电路不被高压冲击损坏。双向结构使其能对正负极性瞬变均有效,适合有反向脉冲或交流耦合的应用场合。600W 的脉冲功率和 58.1A 的峰值脉冲电流表明该器件能承受较强的电磁瞬态(如雷击感应、开关瞬变等)。

四、典型应用场景

  • 5V/3.3V 电源总线和接口保护(USB、系统电源输入)
  • 通信接口与数据信号线防护(RS‑485、CAN 总线、串口)
  • 工业控制设备、PLC 与传感器前端防雷击与浪涌
  • 汽车电子模块的短时浪涌保护(注意汽车应用需符合车规要求)
  • 消费电子外设的端口防静电与过压保护

五、封装与安装建议

SMB 封装利于自动贴装与回流焊接。推荐按照 PCB 厂家的封装图纸设计焊盘并保留适当的散热铜箔,降低瞬态能量吸收时的温升。回流焊温度和曲线请遵循封装材料与工艺规范,避免超出极限温度导致器件性能劣化。

六、选型及注意事项

  • 若保护对象对钳位电压敏感,应注意 Vc=10.5V 是否在可接受范围内;必要时选择钳位更低的型号或配合限流元件使用。
  • 双向器件会在正常工作时出现更高的漏电流与较高的钳位;对电流敏感或寻求更低泄漏的场合可考虑单向 TVS。
  • 长期承受高能量脉冲会影响器件寿命,建议在可能的情况下通过串联摆放、增加熔断/限流保护或采用多级保护设计分散能量。
  • 在汽车或高可靠性场合,确认器件是否满足相应的车规/可靠性认证。

七、储存与可靠性建议

在非工作状态下避免潮湿、高温及机械应力环境存放,长期存储应保持原包装密封并避光。装配时遵守静电防护规范,防止器件在搬运过程中因静电击穿而损坏。

免责声明:上述参数以用户提供的技术数据为准。实际选型请结合具体电路条件、冲击波形(10/1000μs 等)及测试曲线,并向供应商索取完整数据手册与曲线进行验证。

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
