SMF5.0A 产品概述
一、简介
SMF5.0A 是 JSMSEMI（杰盛微）推出的一款单向瞬态电压抑制二极管（TVS），专为低电压系统的瞬态浪涌保护设计。器件工作电压（Vrwm）5V，典型钳位电压9.2V，适用于 I/O 接口、电源线及其它敏感电子元件的浪涌抑制。
二、主要特点
- 极性：单向（单极性）
- 反向截止电压 Vrwm：5V
- 钳位电压 Vc（Ipp 条件下）：9.2V
- 峰值脉冲电流 Ipp：21.7A（10/1000μs 波形）
- 峰值脉冲功率 Ppp：200W @10/1000μs
- 击穿电压 Vbr：6.4V
- 反向漏电流 Ir：200μA（常温）
- 工作温度范围：-55℃ 至 +150℃
- 封装：SOD-123FL，体积小、适合表面贴装
三、典型应用
- 手机、平板及便携设备的 USB/串口/数据线保护
- 汽车电子低压信号线和控制线的瞬态抑制（需确认汽车规范）
- 工业控制、传感器接口、电源输入端的浪涌保护
- 任意对地或对电源线的过压钳位与浪涌吸收场景
四、电气参数说明
- Vrwm = 5V 表示器件在正常反向工作下的最高直流工作电压；用于靠近 5V 总线的保护。
- Vbr（6.4V）为击穿起始电压；在高于此值时进入导通区。
- 钳位电压 9.2V 是在指定脉冲条件下保护时对被保护节点的最高电压，应与被保护器件耐压匹配。
- Ppp 200W（10/1000μs）与 Ipp 21.7A 表明在典型浪涌波形下的能量承受能力，适合中等能量冲击场景。
五、封装与可靠性
SOD-123FL 封装体积小、热阻低，适合自动贴装与回流焊工艺。工作温度范围宽（-55℃~+150℃），在正常使用条件下具备良好长期可靠性。建议在设计时考虑合适的PCB散热与焊点工艺以保证重复冲击后的稳定性。
六、使用建议
- 贴近被保护端口布板，走线尽量短、直，减小寄生电感。
- 对于高能量或连续冲击场景，可并联多只或选型更大功率器件。
- 注意器件钳位电压需高于电路正常工作电压并低于被保护元件最大承受电压。
- 存储和焊接按普通 SMD 器件工艺执行，避免过热超时，防潮处理按厂家推荐进行。

Request for quote
Send RFQ
Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
