P6SMB6.8CA 产品概述

一、产品简介

P6SMB6.8CA 是扬杰(YANGJIE)推出的一款双向瞬态抑制二极管(TVS),采用 SMB(DO-214AA)封装,专为瞬态过压、浪涌和雷击脉冲保护设计。该器件在 10/1000μs 波形下具有 600W 峰值脉冲功率能力,能在工业、通信、电源及汽车周边电路中有效吸收突发能量,保护敏感元件免受过压损坏。

二、主要参数

  • 极性:双向(Bidirectional)
  • 反向截止电压 Vrwm:5.8 V
  • 击穿电压 Vbr:7.14 V
  • 钳位电压 Vc(Ipp 下):10.5 V
  • 峰值脉冲电流 Ipp:57.14 A @ 10/1000 μs
  • 峰值脉冲功率 Ppp:600 W @ 10/1000 μs
  • 反向漏电流 Ir:1 mA(在 Vrwm 条件下)
  • 类型:TVS 二极管
  • 封装:SMB(DO-214AA)

三、关键特性

  • 强劲的浪涌吸收能力:在 10/1000μs 浪涌测试条件下,器件可承受 600W 的脉冲功率,对中长脉冲能量具有良好缓冲能力。
  • 低钳位电压:典型钳位电压 10.5V,可在过压事件发生时将被保护节点电压限制在安全范围,降低后端设备应力。
  • 双向保护:适合交流或可能产生双向过压的线路(如数据线、差分信号线、双向电源保护等),无需额外极性判断。
  • SMB 封装:适配表面贴装工艺,焊接可靠,便于自动化生产与更换。

四、典型应用场景

  • 电源输入及输出防护(DC/AC 电源线浪涌抑制)
  • 通信设备接口保护(以太网、串口等可能出现瞬态过压的信号线)
  • 工业控制设备与传感器节点的浪涌保护
  • 汽车电子系统的辅助线路保护(需注意车规级要求与温度/振动验证)
  • 家用电器和消费电子的输入端过压防护

五、封装与安装建议

SMB(DO-214AA)表贴封装,便于流水线贴片与回流焊接。推荐在待保护线路的靠近入口处布置,尽量缩短连接导线或铜箔长度以降低串联感抗,提高保护效果。焊接时应遵循元件最大回流温度和厂商焊接曲线,避免长时间高温暴露导致性能退化。

六、选型与使用注意事项

  • 确认工作电压:Vrwm(5.8V)应高于正常工作电压,以避免常态漏电或误触发;若系统工作电压接近或高于 Vrwm,应选择更高 Vrwm 的型号。
  • 漏电容与漏电流:Ir 在 Vrwm 条件下为 1 mA,若应用对静态漏电流敏感(如低功耗设备),需评估漏电对系统的影响。
  • 温度与功率降额:在高温或重复脉冲情况下器件承受能力会下降,设计时考虑热量散逸与必要的降额裕量。
  • 与熔断器/限流器配合:在高能量环境中可与保险丝或限流元件结合使用,以防止极端事件损坏保护器件或系统。
  • 可靠性验证:在关键应用(如汽车、航空)中建议做整机级的浪涌与环境验证,确保长期稳定性。

P6SMB6.8CA 在中等能量浪涌抑制场景中表现平衡,适用于需要双向保护与 SMB 表贴方案的多种应用。如需更高功率等级、更低钳位或车规级规范,可根据系统要求选择相应型号或与供应商进一步沟通。

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
