SMF11CA TVS瞬态抑制二极管(TECH PUBLIC / 台舟电子)

一、产品概述

SMF11CA 是一款双向硅瞬态抑制二极管(TVS),由 TECH PUBLIC(台舟电子)提供,适用于对瞬态过电压和浪涌脉冲进行保护的应用。器件设计用于在高能量脉冲(10/1000µs)条件下快速夹紧电压,保护电子线路免受雷击、静电放电或开关瞬变带来的损害。封装为 SOD‑123FL,体积小、易于表面贴装,适合空间受限的保护电路。

二、主要参数

  • 极性:双向
  • 反向截止电压 Vrwm:11 V
  • 击穿电压 VBR(Irr指定):13.5 V
  • 钳位电压(Vc)典型:18.2 V(在峰值脉冲电流下)
  • 峰值脉冲电流 Ipp:11 A
  • 峰值脉冲功率 Ppp:200 W(10/1000µs)
  • 反向电流 Ir:2.5 µA(在 Vrwm 条件下)
  • 工作温度范围:-55 ℃ 至 +150 ℃
  • 封装:SOD‑123FL

三、关键特性

  • 双向结构:无需区分极性,适合交流或可双向传输的信号线保护。
  • 高脉冲承受能力:200 W(10/1000µs)峰值能量,可吸收典型雷电/浪涌能量。
  • 低漏电流:在正常工作电压下 Ir 仅 2.5 µA,适合对静态功耗敏感的系统。
  • 快速响应:在瞬态出现时能迅速进入雪崩区并限制电压,保护下游元件。
  • 宽温度范围:适合工业级环境及高温封装需求。

四、典型应用场景

  • 线路供电及保护:DC/AC 供电总线、汽车电子低压线路(需匹配工作电压)
  • 通信接口:以太网、串口、数据总线等易受浪涌影响的信号线双向保护
  • 工业控制与自动化设备:PLC、传感器信号入口的浪涌抑制
  • 消费电子:电源进线、充电器接口及外设保护

五、使用建议与注意事项

  • 放置位置:尽量靠近被保护线路的入口或连接器,缩短环路面积以提高抑制效果。
  • 能量散热:脉冲能量较高时需注意PCB铜箔散热和环境条件,避免重复大脉冲下器件过热。
  • 连续工况:TVS 设计用于瞬态抑制,不适合承受长期过电压或连续大电流,应与熔断器/热敏电阻等保护元件配合使用。
  • 双向特性:对直流单向供电线路,若需更低钳位电压可考虑单向 TVS;双向更适合交流或双向信号线。

六、封装与可靠性

SOD‑123FL 封装提供了良好的焊接性与机械强度,适合自动化贴装。器件工作温度范围广,符合工业级可靠性要求。推荐在选型时参考 TECH PUBLIC 提供的完整数据手册,确认典型测试条件(如脉冲波形、测量电流)以保证在具体应用中的性能符合预期。

如需样品、尺寸图或更详细的性能曲线(例如 V‑I 特性、能量耗散曲线),建议联系供应商获取技术资料或索取评估样机进行实测验证。

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
