SMF6.5A（TECH PUBLIC 台舟电子）产品概述
一、产品简介
SMF6.5A 是一款单向瞬态电压抑制二极管（TVS），专为对直流电源线和信号线提供瞬态浪涌保护而设计。该器件在静态工作电压下具有低漏电流，在遭受雷击、开关瞬变或电磁干扰时能快速钳位，将过电压能量引导至地线，保护后级电路免受损坏。封装为 SOD-123FL，体积小，便于表面贴装自动化生产。
二、主要电气参数
- 极性：单向
- 反向工作电压 Vrwm：6.5 V
- 击穿电压 VBR（测量条件）：7.98 V
- 钳位电压 Vc（峰值）：11.2 V
- 峰值脉冲电流 Ipp：17.9 A（依据 200 W@10/1000 μs）
- 峰值脉冲功率 Ppp：200 W（10/1000 μs）
- 反向漏电流 Ir：≤ 250 μA
- 工作温度范围：-55 ℃ ～ +150 ℃
- 封装：SOD-123FL
- 类型：TVS（瞬态抑制）
三、核心特点
- 高能量吸收能力：200 W（10/1000 μs）峰值功率，能承受较大浪涌能量。
- 有效钳位：在浪涌条件下钳位电压约为 11.2 V，可限制后级电压幅度。
- 低漏电流：在 Vrwm 下漏电小（≤250 μA），有利于低功耗系统。
- 宽温度范围：-55℃ 至 +150℃，适应严苛环境。
- 小型封装：SOD-123FL 适合空间受限的 PCBA 设计，支持自动贴装。
四、适用场景
SMF6.5A 适合用于 5 V/6 V 级别电源保护、接口防护和一般信号线路防护，如：
- USB、电源输入、点烟器/车载电源等低压电源线路；
- 工业控制、通信设备和消费电子中的浪涌保护；
- 对于需要在恶劣温度环境下工作的设备，提供可靠的瞬态防护。
（注意：本器件为单向 TVS，针对直流或单向突波有效，若用于交流或双向浪涌场合应选择双向型元件。）
五、封装与布局建议
- 推荐将 TVS 靠近受保护端口或电源入端安放，缩短导线长度以降低感性耦合。
- SOD-123FL 对焊接工艺兼容常见回流焊曲线，生产时请参照厂商推荐的焊接温度曲线和 PCB 焊盘设计。
- 为提升散热与浪涌承受能力，必要时可在 PCB 设计中增大焊盘铜面积并做好散热过孔布局。
六、使用注意与采购建议
- 在选型时核对系统最大容许钳位电压，确保 11.2 V 钳位不会超出后级器件耐压。
- 注意器件极性，单向 TVS 的阳极应接地，阴极接被保护线路（或按数据手册标识接法）。
- 生产与存储时按防潮、防静电规范操作，出货前参考 TECH PUBLIC（台舟电子）原厂数据表获取详尽性能与可靠性信息。
- 订购时请确认完整型号、包装规格与合规证书以满足应用要求。
如需更详细的电气曲线、钳位随脉冲电流关系或封装尺寸图，请提供是否需要原厂数据手册，我可进一步整理关键参数供设计核查。

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.
