P6SMB6.8CA 瞬态抑制二极管(TVS)产品概述

P6SMB6.8CA是固得沃克(GOODWORK)推出的一款双向瞬态抑制二极管(TVS),专为低压电路的瞬态过压防护设计,具备宽温适应性、高脉冲耐受能力及小型化封装等特点,广泛应用于工业控制、消费电子、信号接口等领域。

一、产品定位与核心功能

作为TVS核心器件,P6SMB6.8CA的核心作用是快速钳位瞬态过压脉冲:当电路中出现雷击浪涌、静电放电(ESD)、开关瞬态等异常高压时,能在纳秒级时间内由高阻态转为低阻态,将电压钳位在安全范围内,保护后端敏感电子元件(如MCU、传感器、通信芯片等)免受损坏。其双向极性设计无需区分正负极,可同时防护电路正、负方向的过压干扰,简化电路布局。

二、关键参数与性能指标解析

P6SMB6.8CA的参数直接决定防护能力,核心指标及意义如下:

  1. 保护阈值参数:
    • 反向截止电压(Vrwm):5.8V,即器件常态工作不击穿的最大反向电压(建议系统常态电压≤5V,留有余量);
    • 击穿电压(Vbr):7.14V(测试电流Ir=1mA时),是器件开始导通的典型电压,反映初始保护阈值;
    • 钳位电压(Vc):10.5V(峰值脉冲电流下),是器件导通后能钳位的最大电压(后端元件耐压需高于此值)。
  2. 脉冲耐受能力:
    • 峰值脉冲功率(Ppp):600W@1ms,即1ms脉宽浪涌下的最大耐受功率;
    • 峰值脉冲电流(Ipp):57.1A,由Ppp=Vc×Ipp推导得出,反映大电流脉冲耐受能力。
  3. 环境与封装特性:
    • 工作温度:-55℃~+150℃,覆盖工业级宽温范围,适应户外、高温等严苛场景;
    • 封装:DO-214AA(SMB封装),贴片式小型封装(约2.3×1.8mm),适合高密度PCB设计,支持自动贴装。

三、典型应用场景

结合参数特点,P6SMB6.8CA适用于以下场景:

  1. 低压直流电源防护:如5V/3.3V电源线路(消费电子主板、嵌入式系统电源),常态电压低于Vrwm,瞬态时钳位至10.5V保护后级IC;
  2. 信号接口电路:如RS485、USB 2.0、I2C等低速信号接口,双向保护正负脉冲干扰(静电、线间串扰);
  3. 工业控制设备:PLC、传感器节点、远程IO模块等,宽温-55~150℃满足工业现场高低温需求;
  4. 便携电子设备:手机、平板、智能穿戴等,小型DO-214AA封装节省PCB空间,适配紧凑设计;
  5. 车载辅助电路:若符合AEC-Q101车规(需确认具体型号),可用于车载低压辅助电路(仪表盘、传感器)的过压防护。

四、产品优势与设计建议

核心优势

  • 双向防护:无需区分正负极,电路设计更灵活;
  • 宽温可靠:-55~150℃覆盖工业级应用,长期稳定性好;
  • 高脉冲耐受:600W@1ms可应对中等强度浪涌干扰;
  • 小型化封装:DO-214AA适配高密度PCB,降低系统体积。

设计注意事项

  1. 电压匹配:确保系统常态电压≤5V(Vrwm=5.8V留有余量),避免器件长期击穿;
  2. 布局优化:器件靠近被保护电路输入端,减少引线电感(避免钳位电压升高);
  3. 功率扩容:脉冲功率超600W时,可并联多个同型号器件(需保证均流);
  4. 温度余量:高温环境下参数略有漂移,设计预留10%~20%电压余量。

五、品牌与合规说明

P6SMB6.8CA由国内半导体厂商固得沃克(GOODWORK) 生产,该品牌专注过压保护器件研发,产品符合RoHS环保指令(无铅、无镉),部分型号通过AEC-Q101车规认证(需具体确认),可满足不同行业合规要求。

综上,P6SMB6.8CA是一款性价比高、适配性强的低压TVS器件,能有效解决电路瞬态过压问题,是工业、消费电子等领域的常用防护选择。

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.
