SMF15A 单向TVS二极管（SOD-123 封装）产品概述
一、产品概述
SMF15A 是 JSMSEMI（杰盛微）推出的一款单向瞬态电压抑制器（TVS），封装为 SOD-123。器件专为保护低压电子系统与 I/O 接口免受浪涌、电压尖峰和静电放电损害而设计，体积小、响应速度快，适合表贴安装与空间受限的应用。
二、主要参数
- 极性：单向
- 反向工作电压 Vrwm：15 V
- 击穿电压 VBR：16.7 V（Ibr 标准条件）
- 钳位电压 Vc（Ipp 时）：24.4 V
- 峰值脉冲电流 Ipp（10/1000 μs）：8.2 A
- 峰值脉冲功率 Ppp（10/1000 μs）：200 W
- 反向漏电流 Ir：1 μA
- 工作温度范围：-55 ℃ ~ +150 ℃
- 封装：SOD-123
三、主要特性
- 高能量吸收能力（200 W@10/1000 μs），有效限制瞬态电压至安全水平；
- 低静态漏电，适合对待机电流敏感的系统；
- 单向结构对直流电源和外围接口提供优先保护；
- SOD-123 小巧封装，便于自动贴装与批量生产。
四、典型应用场景
- 低压电源线保护（汽车电子、工业控制）
- USB、串口、以太网等 I/O 接口的浪涌抑制
- 电池管理、充电器及便携设备防护电路
- EMI/ESD 抑制与电源总线保护
五、使用与封装注意事项
- 极性必须正确：单向 TVS 在正向导通方向承受浪涌，反向为工作状态；
- PCB 布局应尽量缩短 TVS 到被保护点的连线长度，减少电感环路；
- 若频繁承受大能量冲击，应考虑并联或采用更高功率等级器件以延长寿命；
- 焊接温度与回流曲线按 JSMSEMI 焊接指南执行，避免过热导致封装或电性退化。
六、可靠性与订购信息
SMF15A 适合工业级工作温度并通过常见浪涌测试。订购时请注明型号、封装（SOD-123）与品牌 JSMSEMI。如需样品、器件数据手册或可靠性报告，可联系供应商获取更详尽的参数与应用电路示意。

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.
