SMF5.0CA 产品概述
一、产品简介
SMF5.0CA 是扬杰（YANGJIE）推出的一款双向瞬态抑制二极管（TVS），采用紧凑型 SOD-123FL 表面贴装封装，专为瞬态过电压和浪涌脉冲保护设计。器件在宽温度范围内工作，适配工业级和苛刻环境的抑制需求。
二、主要电气参数
- 类型：TVS（二极管，双向）
- 反向截止电压 Vrwm：5.0 V
- 击穿电压 Vbr：7.07 V
- 钳位电压 Vc（Ipp 对应）：9.2 V
- 峰值脉冲功率 Ppp：200 W（10/1000 μs 波形）
- 峰值脉冲电流 Ipp：21.74 A（10/1000 μs）
- 反向漏电流 Ir（在 Vrwm）：400 μA
- 工作温度：-55 ℃ ～ +150 ℃
- 封装：SOD-123FL
- 品牌：YANGJIE（扬杰）
三、性能特点
- 双向设计，可对正负极性瞬变提供对称保护，适合交流或差分信号线路。
- 200 W（10/1000 μs）的大能量吸收能力，可有效抑制雷击感应和开关浪涌引起的高能脉冲。
- 低钳位电压（9.2 V），在承受峰值脉冲时能将被保护节点电压限制在安全范围内，减少后端元件应力。
- 宽温度范围（-55～150 ℃），满足工业级和部分汽车级环境要求。
四、典型应用场景
- 低压直流电源轨过压保护（5 V 系统保护）
- 通信接口与差分信号保护（如数据线对地或对线间浪涌）
- 工业控制设备、仪表与供电模块的浪涌抑制
- 电源适配器、充电类设备防雷防浪涌保护
五、典型接法与使用注意
- 双向 TVS 通常并联接入被保护线路：跨于正负线或数据对之间，以在瞬变出现时迅速导流。
- 选型时注意 Vrwm（5 V）应高于工作电压且留有裕量，避免在正常工作状态下产生持续漏流。
- 漏电流 Ir=400 μA 在 Vrwm 下可能影响高阻输入或低功耗电路，必要时评估功耗与待机影响。
- 对于长期承受频繁浪涌的场合，应评估器件能量吸收循环寿命并预留热耗散空间。
六、封装与热管理
SOD-123FL 提供小型化表贴形式，便于自动贴装与高密度 PCB 布局。尽管封装紧凑，但在吸收高能量脉冲时会产生显著热量，建议在 PCB 布局中考虑热散路径并配合合适的焊盘与铜箔面积以利散热。
七、选型建议与可靠性
- 如被保护电路工作电压接近 5 V，应优先考虑 SMF5.0CA；若系统对漏电流敏感，可选漏电更小的型号或采取串联高阻限流措施。
- 对于更高能量或更长波形需求，核对 Ppp 波形（10/1000 μs）是否与实际浪涌场景匹配。
- 出货前建议进行样机测试，验证在目标系统中的钳位性能、漏电与热稳定性满足要求。
如需器件 Datasheet、封装尺寸图或在具体电路中的仿真与布局建议，可提供电路信息以便给出更精确的设计支持。

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.
