SMF12A_R1_00001 产品概述

一、产品简介

SMF12A_R1_00001 是 PANJIT(强茂)推出的一款高性能单向 TVS(瞬态电压抑制)二极管,采用 SOD-123FL 小封装,专为汽车电子、通信接口、工业控制与消费类设备提供瞬态过压和静电放电(ESD)保护。该器件标称反向截止电压(Vrwm)为 12V,击穿电压(VBR)13.3V,钳位电压 19.9V,峰值脉冲功率可达 200W,能有效抑制突发高能脉冲,保护下游敏感电路。

二、主要参数

  • 类型:单向 TVS(ESD 保护二极管)
  • 封装:SOD-123FL(小型、低寄生)
  • 反向截止电压 Vrwm:12V
  • 击穿电压 VBR:13.3V
  • 钳位电压(典型):19.9V(在峰值脉冲电流条件下)
  • 峰值脉冲电流 Ipp:10.1A
  • 峰值脉冲功率 Ppp:200W(典型测试波形 10/1000µs)
  • 反向漏电流 Ir:2.5µA
  • 工作温度范围:-55°C ~ +150°C
  • 符合标准:IEC 61000-4-2(ESD 抗扰度)

三、关键特性

  • 高能量吸收:200W 峰值功率能力,能承受短时大能量冲击。
  • 低钳位:在指定脉冲电流下钳位电压 19.9V,降低对后级器件的瞬态应力。
  • 低漏电流:Ir 仅 2.5µA,适合对静态功耗敏感的应用。
  • 宽温度范围:-55°C 至 +150°C,适合严苛环境工作。
  • 小体积封装:SOD-123FL 有利于空间受限设计并降低寄生电容,适配高速信号线保护。

四、典型应用

  • USB、HDMI、Ethernet 等接口的端口保护
  • 汽车电子中 CAN、LIN 总线与传感器接口的过压与 ESD 防护
  • 工业控制、PLC 与变频器的输入输出保护
  • 消费电子产品的电源端口与信号线防护

五、封装与布局建议

  • 建议将 TVS 靠近受保护器件或接口放置,以最小化走线寄生与电感。
  • 为提高吸收能量能力,保证焊盘有良好散热通道并考虑多层板接地。
  • 对于高速差分线,注意器件的寄生电容对信号完整性的影响;SOD-123FL 比较适合兼顾保护与信号质量的场合。

六、可靠性与合规性

  • 满足 IEC 61000-4-2 ESD 抗扰度要求,适用于需要通过电磁兼容测试的产品。
  • 宽温度及低漏电特性使其在汽车与工业领域具有良好长期可靠性。
  • 推荐在实际应用中结合仿真与实验评估钳位性能与热耗散能力。

七、使用注意事项

  • 本器件为单向(UNI),请确认电路是否需要双向保护;双向场合需选择相应型号。
  • 在选择时关注测试条件(如脉冲波形与测试电流),以确保 Ppp、Ipp 与钳位数据在目标工况下满足要求。
  • 对于重复冲击或更高能量需求,应考虑并联或使用更高功率等级的保护方案。

SMF12A_R1_00001 以其高能量吸收、低漏电和紧凑封装,适合在对空间、可靠性和抗扰度有较高要求的电路中作为首选的瞬态抑制器件。请结合具体系统需求与数据手册进行最终选型与布局验证。

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
