SMAJ15CA 产品概述
一、产品简介
SMAJ15CA 是富芯森美（FUXINSEMI）推出的一款双向瞬态抑制二极管（TVS），采用SMA（DO-214AC）低剖面表面贴装封装设计。器件针对10/1000 μs波形的浪涌能量提供400W峰值脉冲功率（占空比0.01%），在狭小电路板空间内实现高效的过压保护。
二、主要电气参数
- 极性：双向
- 反向工作电压 Vrwm：15 V
- 击穿电压 VBR（Ibr测量点）：16.7 V
- 钳位电压（Ipp=16.4 A）：24.4 V
- 峰值脉冲电流 Ipp：16.4 A（对应10/1000 μs）
- 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：5 μA
- 工作温度范围：-55 ℃ ~ +150 ℃
三、关键特性与优势
- 高能量吸收：针对10/1000 μs波形优化，400W峰值脉冲功率能有效吸收雷击及工业浪涌能量。
- 优秀钳位性能：24.4V的钳位电压保证在浪涌发生时被保护线电压迅速受控，减少下游器件应力。
- 低增量浪涌电阻：提升系统在高电流冲击下的稳定性与保护效率。
- 快速响应：从0V到VBR的响应快速（单向型通常小于1 ns，双向型约5 ns），能够在瞬态初期即限制过压。
- 可靠制造：玻璃钝化芯片结工艺、无铅且符合RoHS与无卤要求，适配现代环保与可靠性要求。
- 宽温工作：-55 ℃~+150 ℃适用于工业与汽车级工作环境。
四、典型应用场景
- 通信接口保护（如以太网、串口等）
- 电源线路与配电模块的浪涌保护
- 工业控制设备与测量仪器的输入保护
- 汽车电子系统中对瞬态高压保护（在符合系统设计要求下）
五、封装与布局建议
SMA（DO-214AC）表面贴装封装便于自动贴装加工。为发挥最佳保护效果，建议：
- 将TVS尽量靠近需要保护的端口或连接器放置，以降低互联感性和环路面积；
- 使用宽、短的走线及低阻抗回流路径，必要时在焊盘下方或附近添加散热/接地过孔以增强热耗散；
- 遵循器件制造商推荐的回流焊工艺曲线，避免超出最大结温。
六、选型与可靠性注意
选择时请核对系统最大工作电压、允许钳位电压以及浪涌波形（10/1000 μs或8/20 μs等）的一致性。对于频繁或更高能量的冲击环境，应考虑并联或选用更高功率等级的TVS。器件玻璃钝化与宽温特性提高了长期可靠性，但仍需在规范的使用条件下保证寿命。
如需器件数据手册、封装尺寸图或样品订购信息，请提供具体用途与数量，以便进一步匹配最佳替代型号与应用建议。

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.
