SMFJ5.0CA 双向瞬态抑制二极管（TVS）产品概述
一、产品核心定位
SMFJ5.0CA是FUXINSEMI（富芯森美）推出的低电压双向TVS瞬态抑制二极管，针对5V供电系统的过压防护需求设计，可有效抑制静电放电（ESD）、电快速瞬变脉冲群（EFT）等瞬态干扰，保障敏感电子电路的可靠性。产品符合IEC 61000-4-2防护标准，适用于多类电子设备的接口、电源线路防护场景。
二、关键电气性能参数详解
SMFJ5.0CA的核心参数围绕“低电压防护”和“脉冲耐受能力”设计，具体如下：
- 极性与截止特性：双向导通设计，无需区分电路正负极，简化PCB布局；反向截止电压（Vrwm）为5V，正常工作时反向电压不超过5V则保持截止，不影响电路功能。
- 过压防护触发：击穿电压（Vbr）为7V，过压超过7V时快速导通泄放能量；峰值脉冲下钳位电压（Vc）为9.2V，将后级电路电压限制在安全范围（远低于多数5V芯片最大耐压）。
- 脉冲耐受能力：峰值脉冲电流（Ipp）达21.7A，峰值脉冲功率（Ppp）为200W，可承受单次强脉冲冲击；反向漏电流（Ir）仅400μA，截止状态对电路功耗影响极小。
- 通道配置：单路通道设计，适配单电源、单信号线路的独立防护需求。
三、机械与环境适应性
- 封装形式：采用SOD-123表面贴装封装，尺寸紧凑（小体积设计），兼容自动化贴装工艺，适合高密度PCB布局（如便携设备、小型模块）。
- 宽温工作范围：工作温度覆盖-55℃至+150℃，可适应工业级、汽车电子等严苛环境（如低温存储、高温工作场景）。
- 标准合规性：防护等级符合IEC 61000-4-2（ESD防护），能有效抵御人体接触静电、设备插拔静电等常见干扰源。
四、品牌与典型应用场景
- 品牌优势：FUXINSEMI（富芯森美）作为专业半导体厂商，SMFJ5.0CA通过稳定工艺保障参数一致性，适用于批量生产场景。
- 典型应用：
- 消费电子：手机、平板、智能穿戴的5V充电口、接口线路防护；
- 工业控制：PLC模块、传感器接口的瞬态干扰抑制；
- 通信设备：路由器、交换机的5V电源与信号口防护；
- 汽车电子：低电压辅助电路（如仪表盘、传感器模块）的过压防护（依托宽温特性）。
五、产品总结
SMFJ5.0CA凭借双向防护、低钳位电压、强脉冲耐受能力及宽温适应特性，成为5V系统过压防护的高性价比选择。其小尺寸封装与自动化贴装兼容性，满足现代电子设备小型化、高密度设计需求，广泛适配多领域电子电路的瞬态干扰防护场景。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
