P4SMA6.8CA 产品概述
一、概述
P4SMA6.8CA 是富芯森美（FUXINSEMI）推出的一款双向瞬态电压抑制二极管（TVS），采用低轮廓表面贴装 DO-214AC（SMA）封装，面向电路输入/接口的浪涌与瞬态过压保护。器件具备高能量吸收能力与优良的钳位性能，适合在空间受限的板级保护场合使用，且产品为无铅并符合 RoHS 与无卤要求。
二、主要电气参数
- 极性：双向
- 反向截止电压 Vrwm：5.8 V
- 击穿电压 VBR：6.45 V
- 钳位电压（典型）：10.5 V
- 峰值脉冲电流 Ipp：40 A（10/1000 μs 波形）
- 峰值脉冲功率 Ppp：400 W（10/1000 μs，重复率/占空比 0.01%）
- 反向漏电流 Ir：1 mA（在 Vrwm 条件下典型）
- 响应时间：从 0 V 到 VBR 响应极快（单向通常 <1 ns，双向约 5 ns）
- 芯片结构：玻璃钝化结
三、关键特性
- 高能量吸收：单次 10/1000 μs 波形下可承受 400 W 峰值脉冲功率，能有效钳制来自雷击、开关瞬变等的高能脉冲。
- 低钳位电压：典型 10.5 V 钳位，可在保护目标电路的同时降低剩余应力。
- 低增量浪涌电阻：在大电流冲击下保持较低压降，提高保护效率。
- 表面贴装、低轮廓：DO-214AC (SMA) 封装优化电路板空间，便于自动化贴装与回流焊工艺。
- 可靠性设计：玻璃钝化芯片结提高结面稳定性，器件耐湿热与长期可靠性良好。
- 环保合规：无铅、RoHS 及无卤材料要求符合现代电子产品环保规范。
四、典型应用场景
- 电源输入与分配线路防护（如适配器、开关电源输入端）
- 通信接口与数据线防护（以太网、DSL、串行总线等）
- 工业控制与自动化设备的浪涌保护
- 消费电子产品的板级过压保护（例如充电器、主板外围）
- 基础设施设备（监控、电力、楼宇自控）中的瞬态抑制
五、封装与可靠性说明
P4SMA6.8CA 采用 DO-214AC（SMA）表面贴装封装，适合标准 SMT 工艺与回流焊。器件为玻璃钝化芯片结，整体结构对热冲击与湿度有良好抵抗能力。为保证最佳性能，建议在推荐的 PCB 布局下使用：靠近需要保护的输入端放置、并提供适当的散热路径与较短的接地回路。
六、选型与注意事项
- 本型号为双向 TVS，适用于交流或双向瞬态的防护场合；若仅需单向保护，可选择相应单向型号。
- 在选型时关注 Vrwm 与被保护电路的工作电压匹配，以确保在正常工作下漏电流在可接受范围内（Ir 典型 1 mA）。
- 对于高频敏感信号线，需评估 TVS 的寄生电容对信号完整性的影响。
- 采用时请参考厂方完整的电气特性曲线、热阻与包装信息，结合系统的最大允许钳位电压与浪涌能量做可靠性验证。

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.
