SMF6.5CA 产品概述
一、简介
SMF6.5CA 是台舟电子（TECH PUBLIC）提供的一款双向瞬态电压抑制器（TVS），用于抑制脉冲过电压和短时浪涌。器件设计用于在双向电路中钳制瞬态电压，保护敏感电子元件免受雷击、开关瞬变或静电放电等干扰。
二、主要参数
- 极性：双向
- 反向截止电压 VRWM：6.5 V
- 击穿电压（典型）：7.98 V
- 钳位电压 Vc（峰值）：11.2 V
- 峰值脉冲电流 Ipp：17.9 A（10/1000 μs 波形）
- 峰值脉冲功率 Ppp：200 W（10/1000 μs 波形）
- 反向电流 Ir：≤250 μA
- 工作温度：-55 ℃ ～ +150 ℃
- 封装：SOD-123FL（小型表面贴装）
- 器件类型：TVS 二极管（未分类）
三、应用场景
- 通信接口与数据线防护（如串口、CAN、USB 等双向信号线）
- 电源轨和电源输入端的浪涌保护（尤其是需双向钳位的二极管替代场合）
- 工业设备、仪表及汽车电子等对瞬态耐受性要求较高的领域
- 需要小尺寸、易于贴装的 PCB 防护方案
四、封装与可靠性
SOD-123FL 封装提供紧凑的占板面积和良好的焊接可靠性，适合自动贴装与回流焊工艺。器件工作温度范围宽（-55℃ 至 +150℃），适应恶劣环境与高温工况，但长期承受高能量脉冲应遵循额定脉冲功率与散热条件。
五、设计与使用建议
- 布局上尽量缩短 TVS 与被保护端之间的走线，减小串联电感与环路面积；
- 对于重复脉冲或高能量环境，考虑采用并联或更高功率等级的 TVS 分担能量；
- 避免将 TVS 用作连续限压元件，长期稳态电流应限制在器件反向电流范围内；
- 在汽车或工业级应用中，关注焊接工艺与热回流曲线，确保封装机械与热稳定性。
SMF6.5CA 以其双向钳位特性、小型封装与较高的脉冲承受能力，适合在空间受限且需可靠瞬态保护的电子设计中广泛采用。

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.
