SMF10CA(10V)产品概述

一、产品概述

SMF10CA 为晶导微电子推出的一款 TVS(瞬态电压抑制)二极管,采用 SOD-123FL 表贴封装,针对电源和信号线的瞬态过压浪涌提供高速、可靠的钳位保护。器件工作温度范围宽(-55℃ 至 +150℃),在 10/1000μs 浪涌波形下可承受高达 200W 的峰值脉冲功率,适合汽车、工业与通信等对抗浪涌能力和温度稳定性要求较高的场合。

二、主要电气参数

  • 钳位电压(Vc):17V(在 10/1000μs、Ipp 条件下)
  • 工作反向电压(Vrwm):10V
  • 击穿电压(Vbr):12.3V
  • 峰值脉冲功率(Ppp):200W @ 10/1000μs
  • 峰值脉冲电流(Ipp):11.8A @ 10/1000μs
  • 反向电流(Ir):2.5μA(在 Vrwm 条件)
  • 类型:TVS(二极管)
  • 封装:SOD-123FL(表面贴装)
  • 品牌:晶导微电子
  • 工作温度:-55℃ ~ +150℃

三、关键特性与优势

  • 高浪涌吸收能力:200W 的峰值脉冲功率与 11.8A 的峰值电流能力,能够有效吸收工业及汽车场景下的大能量瞬态冲击。
  • 低钳位电压:在规定脉冲条件下钳位至 17V,能在保护设备的同时减少过压对后端电路的冲击。
  • 低反向泄漏:Vrwm 下反向电流仅 2.5μA,有利于低功耗系统和精密模拟电路的可靠性。
  • 宽温度工作范围:-55℃ 至 +150℃,适合高温或严苛环境应用。
  • 紧凑封装:SOD-123FL 体积小,便于在空间受限的 PCB 上布置且兼容常规回流焊工艺。

四、典型应用场景

  • 汽车电子:车载电源线、传感器线、通讯总线等需要抵御启动/关闭瞬变和感性负载回路的应用。
  • 工业控制:电机驱动、PLC、工业以太网、I/O 接口等抗浪涌保护。
  • 通信与网络设备:保护供电线、串行/并行接口及中继设备防止雷击/浪涌引起的故障。
  • 消费电子与电源模块:用于 USB、DC 电源输入侧的过压浪涌保护。

五、封装与使用建议

  • 布局:将器件尽量靠近被保护接口或电源入口放置,减小线路感抗与寄生电感,提升钳位效率。
  • 接地:对于单端保护,将 TVS 的参考端直接接大面积地平面;对于高能量保护,建议增加金属平面或热沉以分散热量。
  • 焊接工艺:SOD-123FL 支持标准回流焊,遵循厂商给出的温度曲线以避免封装或内部结构损伤。
  • 保护设计:TVS 为瞬态吸收器件,不应作为连续稳压元件使用;对高频或精密信号线保护时,需考虑器件电容带来的影响(必要时选用低容抗 TVS)。

六、可靠性与选型注意

  • 能量限制:峰值功率与脉冲电流是基于 10/1000μs 波形的条件,若遭遇其他波形或重复浪涌,应按能量累计和热性能进行降额使用或选用更高规格器件。
  • 型号确认:在系统设计前核对产品完整型号与数据手册,确认是否为单向或双向 TVS(不同后缀可能表示不同极性特性)。
  • 环境与寿命:在高温或频繁浪涌场合,应关注热循环与封装应力对长期可靠性的影响,并考虑额外的热管理或并联冗余设计。
  • 兼容性:若保护对象为高速差分信号,应评估 TVS 的电容和导通特性对信号完整性的影响,必要时选择专用的低容抗 TVS。

总结:SMF10CA(10V,SOD-123FL)以其高能量吸收能力、低泄漏、电压钳位性能和宽工作温度,适合多种工业、汽车与通信领域的瞬态过电压保护需求。选型时应结合实际脉冲能量、封装热散、布线和信号完整性要求做综合评估。

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
