SMF58A-TP 瞬态抑制二极管(TVS)产品概述

一、产品基本信息

SMF58A-TP是由Micro Commercial Co(MCC,美微科) 生产的单向瞬态抑制二极管(TVS),属于通用型电路保护器件。产品以卷带(TR) 包装,适配自动化贴装;零件状态为有源,可直接投入电路使用;具备1个单向通道,仅在反向瞬态过压时导通防护,正向无保护功能;未集成电源线路保护,适用于信号接口、非电源线路的瞬态干扰防护场景。

二、核心性能参数

SMF58A-TP的核心参数围绕“瞬态过压防护能力”设计,关键指标及意义如下:

  1. 反向断态电压(典型值):58V
    器件正常工作时的反向最大允许电压,低于此值时处于截止状态,不影响电路正常信号传输。
  2. 击穿电压(最小值):64.4V
    反向电压超过此值时,器件开始击穿导通,启动防护机制,将过压能量转移至地或电源端。
  3. 箝位电压(最大值):93.6V
    承受峰值脉冲电流2.1A(10/1000µs波形) 时的最大箝位电压,可将下游电路电压限制在安全范围,避免敏感元器件(如MCU、传感器)损坏。
  4. 峰值脉冲功率:200W
    器件可承受的最大瞬态脉冲功率,反映对强干扰(雷击、静电放电ESD、电快速瞬变EFT)的耐受能力,满足多数通用电子设备的防护需求。

三、封装与安装方式

SMF58A-TP采用SOD-123FL封装,属于小型表面贴装型(SMD)封装,尺寸紧凑(约1.6mm×0.8mm),可显著节省PCB空间,适配高密度电路设计(如便携设备、小型通信模块)。
安装方式为表面贴装,兼容常规SMT工艺(回流焊、波峰焊),支持自动化批量生产,降低人工成本与贴装误差。

四、典型应用场景

作为通用型TVS二极管,SMF58A-TP适用于多种电子设备的瞬态干扰防护,常见场景包括:

  1. 消费电子:手机、平板、智能手表的USB接口、充电端口防护,抵御静电放电、电快速瞬变脉冲群干扰;
  2. 工业控制:PLC(可编程逻辑控制器)、传感器节点的信号接口防护,防止工业现场电磁干扰损坏敏感电路;
  3. 通信设备:路由器、交换机、无线基站的RJ45接口、射频端口防护,应对雷击、浪涌等瞬态过压;
  4. 汽车电子(扩展场景):因工作温度覆盖-65℃~175℃,可用于汽车低压辅助电路(如车载显示屏、传感器)的瞬态防护(需结合实际电路验证)。

五、工作环境与可靠性

SMF58A-TP的工作温度范围为**-65℃175℃**,覆盖工业级(-40℃85℃)及部分高温环境(如汽车发动机舱附近)的温度要求,具备较强环境适应性。
MCC采用稳定封装工艺,器件引脚与封装材料结合牢固,可在长期恶劣环境下保持可靠性能,降低因器件失效导致的设备故障风险。

六、品牌与制造商背景

MCC(美微科)是全球知名半导体供应商,专注于保护器件、功率器件、二极管等产品的研发与生产,产品广泛应用于电子、通信、汽车、工业领域。
SMF系列是MCC推出的小型表面贴装TVS产品线,覆盖多种电压等级,以高可靠性、宽温度范围、紧凑封装为核心优势,满足不同客户的防护需求。

SMF58A-TP凭借其平衡的防护性能、紧凑封装与宽温度范围,成为通用电子设备瞬态干扰防护的高性价比选择。

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
