SMF7.5CA TVS二极管产品概述

一、产品基本属性

SMF7.5CA是一款双向瞬态抑制二极管(TVS),由SHIKUES(时科)半导体推出,采用SOD-123FL小型表面贴装封装,核心作用是为电子设备提供过压/静电防护——当遭遇浪涌脉冲(静电放电、电源尖峰、雷击感应等)时,快速钳位电压至安全范围,保护后级敏感元件(IC、传感器、通信模块等)免受损坏。双向极性设计无需区分正负极安装,简化了电路设计与生产工艺。

二、核心电性能参数解析

SMF7.5CA的电参数经过严格标定,关键指标适配低压电路防护需求:

  1. 反向截止电压(Vrwm):7.5V
    正常工作时可承受的最大反向电压,无击穿风险,适配3.3V、5V等低压系统(≤7.5V)。
  2. 击穿电压(Vbr):典型值9.21V
    反向电压超Vrwm后进入击穿状态,电压稳定在9.21V左右,为钳位动作做准备。
  3. 钳位电压(Vc):12.9V
    10/1000μs浪涌波形下的最大钳位电压,远低于多数敏感IC的损坏阈值,直接降低后级器件损坏概率。
  4. 浪涌耐受能力
    • 峰值脉冲电流(Ipp):15.5A(10/1000μs波形)
    • 峰值脉冲功率(Ppp):200W(10/1000μs波形)
      可覆盖常见静电放电、电源开关瞬态等浪涌场景,应对中等强度冲击。
  5. 反向漏电流(Ir):50μA
    正常工作时漏电流极低,不影响低功耗设备(可穿戴、物联网节点)的续航。
  6. 工作温度范围:-55℃~+150℃
    宽温适配极端环境(工业低温车间、汽车高温引擎舱、户外通信设备)。

三、封装与可靠性设计

SMF7.5CA采用SOD-123FL表面贴装封装,具备以下优势:

  • 小型化:尺寸紧凑(约2.5mm×1.6mm×1.0mm),节省PCB空间,适配高密度电路(智能手机主板、小型通信模块);
  • 可靠性:耐高温封装材料+宽温设计,长期使用性能稳定,抗机械应力能力强;
  • 环保性:符合RoHS无铅标准,满足全球电子设备环保要求。

四、典型应用场景

SMF7.5CA的双向保护、低钳位电压特性,使其适用于多领域低压电路防护:

  1. 消费电子:智能手机、平板的充电/数据接口(USB、Type-C)ESD防护,避免静电损坏主板IC;
  2. 通信设备:路由器、交换机的以太网端口、射频接口防护,应对雷电感应浪涌;
  3. 汽车电子:车载12V系统传感器、显示屏接口过压保护,适配汽车宽温环境;
  4. 工业控制:PLC输入输出端口、传感器节点浪涌防护,适应工业现场电磁干扰;
  5. 物联网设备:智能门锁、智能家居传感器接口保护,低漏电流不影响续航。

五、品牌与应用优势

SHIKUES(时科)作为专业半导体厂商,SMF7.5CA具备以下竞争力:

  • 双向无极性:安装无需分正负,简化生产流程,降低出错率;
  • 低钳位电压:12.9V保护效果显著,减少后级器件损坏;
  • 宽温可靠性:-55℃~+150℃覆盖绝大多数场景;
  • 高一致性:批量参数稳定,适配工业化生产;
  • 成本效益:性能均衡,价格适中,是低压防护的高性价比选择。

SMF7.5CA凭借其双向保护、宽温耐受与小型化设计,成为低压电子设备浪涌防护的可靠方案,可满足消费电子、通信、汽车等多领域的防护需求。

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
