P6SMB6.8CA 产品概述

一、产品简介

P6SMB6.8CA 为 UMW(友台半导体)出品的双向瞬态电压抑制器(TVS),用于对抗静电放电(ESD)与电源/信号线浪涌冲击。器件封装为 SMB,适合中等功率、需要PCB表贴保护的工业与消费电子应用,型号标识清晰,可靠性设计用于满足现场电磁兼容防护要求。

二、主要电气参数

  • 类型:双向 TVS(ESD/浪涌防护)
  • 反向截止电压 Vrwm:5.8 V(额定驻留/工作电压)
  • 击穿电压 Vbr:约 6.45 V(典型)
  • 钳位电压 Vc:约 10.5 V(峰值脉冲条件下的钳位值)
  • 峰值脉冲功率 Ppp:600 W(10/1000 µs 波形)
  • 峰值脉冲电流 Ipp:57.1 A(对应上述功率/波形)
  • 反向漏电流 Ir:约 1 mA
  • 极性:双向(可用于交流或双向信号线路)
  • 防护等级:符合 IEC 61000-4-2(ESD)与 IEC 61000-4-4(EFT)规范

三、典型应用

  • 串行通信接口、差分信号保护(如 RS-485、CAN)
  • 电源线及充电口的浪涌和静电保护
  • 工业控制设备、楼宇自控、仪表前端的抗干扰设计
  • 消费类电子中需要中等能量耐受的端口保护

四、封装与布局建议

  • 封装:SMB(表面贴装),适合自动贴装生产。
  • 布局建议:器件应尽量靠近需保护的端口或连接器放置,走线短、回路面积小以减小寄生电感;建议旁路电容与地线宽而短,保证低阻抗回流路径。对于双向器件,注意两端对称布局。

五、设计要点与注意事项

  • 选择 Vrwm 时应确保其高于最大工作电压,P6SMB6.8CA 的 Vrwm 为 5.8V,适合 5V 类系统需谨慎评估。
  • 钳位电压 10.5V 为在规定冲击条件下的保护电压,设计时需确认被保护器件能承受该瞬态电压。
  • 反向漏电流约 1 mA,长时间并联使用或在低功耗系统时需考虑对电路的影响。
  • 热管理:在频繁或高能量浪涌环境下考虑散热及器件热排布,保证可靠性。
  • 测试与验证:在目标系统上进行实际浪涌/ESD 测试,验证布局、接地与器件性能满足 EMC 要求。

本器件适用于对中等能量脉冲有较高抗扰要求的场合,结合合理的 PCB 布局与电源/地线设计,可为端口与系统提供可靠的瞬态过压保护。若需更详尽的电气曲线或封装尺寸图,请参阅 UMW 官方数据手册。

Sourcing availability signal

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
