SMFJ5.0CA 产品概述
一 产品简介
SMFJ5.0CA 是华轩阳电子（HXY MOSFET）推出的一款双向瞬态电压抑制二极管（TVS），封装为 SOD-123FL。器件专为保护微型电路与接口电源免受瞬态过压（如雷击、电感负载开关、静电放电等）冲击设计，适合 5V 及近似电压等级的信号线和电源线保护应用。
二 主要电气参数
- 极性：双向（Bidirectional），可抑制正负双向突波。
- 反向截止电压 Vrwm：5V（稳态工作电压，器件在此电压下应保持低泄漏）。
- 击穿电压 Vbr：约 6.4V – 7.0V（器件进入雪崩导通的电压范围）。
- 钳位电压 Vc：9.2V（在峰值脉冲电流下的典型钳位电压）。
- 峰值脉冲电流 Ipp：21.7A（对应规格的脉冲测试条件）。
- 峰值脉冲功率 Ppp：200W（脉冲能量能力，具体测量波形与时长依规格书）。
- 反向电流 Ir：400µA（在 Vrwm 条件下的漏电流量级）。
- 类型：TVS 二极管，型号 SMFJ5.0CA。
以上参数为器件典型/额定值，详细测试条件与极限请参照完整规格书。
三 特性与优势
- 双向保护：适用于可能出现正负电压摆幅的信号线或差分接口，如数据总线、通信接口。
- 高能量吸收能力：200W 峰值功率与 21.7A 峰值脉冲电流，能在短时冲击下有效钳位，保护后端电路。
- 紧凑封装：SOD-123FL 小型低剖面，便于表面贴装，节省 PCB 面积并利于自动化生产。
- 设计于 5V 等级：Vrwm=5V 使其非常适合 USB、TTL、I²C、串口及 5V 电源轨的浪涌保护。
四 典型应用场景
- USB、串口和 I/O 接口的浪涌与静电保护。
- 5V 单片机、电源轨保护。
- 消费类电子、通信设备、仪表仪器中的接口保护。
- 需要双向保护的差分信号或可反向连接的电路。
五 封装与使用建议
- 封装：SOD-123FL，适合常规贴片工艺。推荐按照厂方典型焊盘尺寸设计 PCB，保证良好焊接与散热路径。
- 布局建议：将 TVS 靠近受保护的连接器或器件放置，尽量缩短寄生感抗，使用宽短走线接地；若为双面 PCB，优先采用大地平面以提高散热与能量分流能力。
- 安装注意：避免在超过器件额定功率和重复冲击条件下长期工作，如需更高能量吸收应并联或选用更高规格器件。
六 选型与注意事项
选择 SMFJ5.0CA 时，确认系统的最大工作电压、允许的泄漏电流及所需的钳位电压是否匹配。对于连续高能量或汽车高压环境，应选择对应级别的汽车级或更高功率 TVS。同时建议参考完整数据手册中的冲击波形（如 10/1000µs、8/20µs 等）下的参数，以确保在特定脉冲条件下器件能可靠工作。

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.
