SMFJ24CA 产品概述
一、产品简介
SMFJ24CA 是伯恩半导体（BORN）推出的双向瞬态电压抑制器（TVS/ESD），封装为 SOD-123FL，专为静电放电和浪涌事件的瞬态抑制设计。器件在 24V 工作电压等级（Vrwm=24V）下工作稳定，提供对正负极性脉冲的对称保护，适合各种低压接口与电源线路的防护需求。
二、关键参数
- 钳位电压（Vclamp）：38.9V（典型，通常对应峰值脉冲电流条件）
- 击穿电压（Vbr）：29.5V
- 反向截止电压（Vrwm）：24V
- 峰值脉冲功率（Ppp）：200W @ 10/1000 μs
- 峰值脉冲电流（Ipp）：5.1A
- 反向漏电流（Ir）：1 μA（典型）
- 极性：双向（Bidirectional）
- 类型：TVS（瞬态电压抑制器）
- 包装：SOD-123FL（表面贴装）
- 防护等级：符合 IEC 61000-4-4（脉冲群）与 IEC 61000-4-2（ESD）规范
三、产品特性与优势
- 双向对称抑制，能有效钳制正负极性瞬态脉冲，无需额外极性判断或旁路器件。
- 高能量吸收能力（200W@10/1000 μs），能承受瞬间浪涌与冲击，适合电源与信号线防护。
- 低漏电流（约 1 μA），对电路的静态功耗影响极小，适合对待机功耗敏感的系统。
- SOD-123FL 小尺寸封装，便于高密度 PCB 布局与自动化贴装。
四、典型应用场景
- 工业与楼宇自动化的 24V 电源线路保护
- 通信接口与数据总线（如串口、差分信号线、I/O 口）的浪涌与 ESD 防护
- 消费电子设备接口保护、模块间接口保护
- 需满足 IEC 61000-4-2/4-4 抗扰度要求的设备
五、安装与使用建议
- 双向 TVS 应直接跨接在需保护的线对之间（或线对对地，视电路拓扑而定），尽量靠近受保护器件布置，减小走线感抗与寄生电感。
- 考虑 PCB 熔断器、限流电阻等配合使用时注意不会影响 TVS 的响应性能。
- 在高能量冲击场合，注意 PCB 铜皮与散热设计，确保脉冲能量能够有效导出。
- 储存与贴装遵循标准静电防护流程，避免器件在加工阶段遭受过度静电损伤。
六、选型提示
若系统工作电压接近 24V 或需对称双向保护，且要求符合 IEC 61000-4-2/4-4 标准，SMFJ24CA 在能量吸收、低漏电与小尺寸封装方面具有良好性价比。对于更高能量或更大持续电流需求，应参考更高 Ppp 或更大 Ipp 规格的器件。

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.
