SMF5.0A 瞬态抑制管(TVS)产品概述

一、产品简介

SMF5.0A 是时科(SHIKUES)推出的一款单向瞬态抑制二极管,封装为 SOD-123FL,专为5V电源与信号线的浪涌和瞬态过压保护设计。器件响应迅速、钳位电压低、耐冲击能力强,适用于消费电子、通信设备和工业控制等需要稳健抗干扰的场合。

二、主要电气参数

  • 极性:单向
  • 反向截止电压 Vrwm:5V(适配5V电源轨)
  • 击穿电压(Vbr):7V
  • 钳位电压 Vc(Ipp):9.2V
  • 峰值脉冲电流 Ipp:21.7A @ 10/1000µs
  • 峰值脉冲功率 Ppp:200W @ 10/1000µs
  • 反向电流 Ir:400µA(在Vrwm条件下)
  • 工作温度范围:-55 ℃ ~ +150 ℃
  • 类型:TVS(瞬态电压抑制管)
  • 封装:SOD-123FL

以上参数反映了本器件在单次大能量脉冲下的钳位与承受能力,以及在常温工作时的泄漏特性与环境适应性。

三、核心特点与优势

  • 针对5V系统优化:Vrwm=5V,适配常见5V电源和信号线保护。
  • 低钳位电压:在21.7A脉冲条件下钳位约9.2V,有效限制过压幅度,保护下游器件。
  • 高能量吸收能力:200W(10/1000µs)脉冲功率,适合汽车电子、工业控制环境中的浪涌防护需求(单次脉冲)。
  • 宽工作温度:-55~+150 ℃,能满足苛刻环境下长期稳定工作。
  • 小型封装:SOD-123FL 占板面积小,便于高密度 PCB 布局。
  • 单向结构:对直流电源线提供更准确的单向过压保护。

四、典型应用

  • 5V 电源轨保护(主板、嵌入式系统、模块电源输入)
  • USB、串口等通讯接口浪涌保护
  • 工业控制设备与传感器接口防护
  • 通信基站、路由器等设备的电源与信号防护
  • 电池管理与便携设备的输入端瞬态抑制

五、封装与安装建议

  • 推荐采用标准 SOD-123FL PCB 孔位与焊盘布局,保持焊盘与器件引脚良好焊接以利热散。
  • 焊接方式建议按无铅回流工艺曲线进行,避免超温时间过长。
  • 布局时将 TVS 的地端尽可能短且直连至系统地,减少环路电感以提高抑制效果。
  • 对于高能量或重复脉冲场合,建议在 TVS 周围留有足够铜箔面积或热沉结构以辅助散热。

六、使用与可靠性注意事项

  • 本器件的 Ipp 与 Ppp 为单次脉冲能力,重复或频繁的脉冲应参考供应商建议进行降额使用或增加并联/级联保护措施。
  • TVS 不能替代熔断器或限流元件;在强短路或持续过压情况下应配合限流装置使用。
  • 反向泄漏电流会随温度上升而增加,应在高温条件下校核泄漏对系统待机或精密测量的影响。
  • 订购与批量应用前建议索取完整数据手册,并在目标系统中做实际浪涌测试验证。

七、订购与技术支持

常用型号:SMF5.0A(SHIKUES / 时科,封装 SOD-123FL)。采购与样品、订货包装(卷带/散装)信息请联系时科研发或授权分销商获取详细料号与库存。购买前请务必确认具体应用环境与极限参数,以便选型最优的保护方案。

总结:SMF5.0A 在小型封装下提供了针对5V系统的一致性钳位与较高脉冲吸收能力,是保护电源与接口免受瞬态冲击的可靠选择。

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
