SMAJ10CA（Brightking 台湾君耀）产品概述
一、产品简介
SMAJ10CA 为双向瞬态电压抑制二极管（TVS），封装为SMA（DO‑214AC），主要用于抑制电源线和信号线上的瞬态过电压和静电放电。额定反向工作电压 Vrwm 为 10V，典型击穿电压 12.3V，钳位电压约 17V，能在浪涌冲击时快速钳位，保护下游电子器件免受损坏。
二、主要电气参数
- 极性：双向（对称钳位，适合交流或双向脉冲环境）
- 反向截止电压 Vrwm：10V
- 击穿电压（Vbr）：12.3V
- 钳位电压 Vc：17V（典型）
- 峰值脉冲电流 Ipp：23.5A（10/1000μs）
- 峰值脉冲功率 Ppp：400W（10/1000μs）
- 反向电流 Ir：5μA（在 Vrwm 下）
- 工作温度：-55℃ 至 +150℃
- 防护等级：符合 IEC 61000‑4‑2 静电放电防护要求
三、性能特点与优势
该器件具有响应速度快、钳位电压低、漏电小、耐冲击能量高等优点。双向结构无需区分极性，便于在交流信号或差分线上使用。SMA 封装兼顾体积与散热能力，适合表面贴装工艺，便于自动化生产。
四、典型应用场景
适用于通信设备、工业控制、路由器、开关电源输入端、接口保护（如串口、以太网非隔离端口）及一般 5V~12V 级别电源和信号线的浪涌与 ESD 防护。对于高能量雷击或更严苛的汽车电气瞬态，应结合系统级保护设计选型。
五、使用与布局建议
- 将 TVS 尽量靠近受保护端口或器件放置，缩短引线路径以降低寄生感抗。
- 对于高能量冲击，考虑在输入端配合限流电阻或熔断器使用，避免单颗器件承受过载。
- 采用推荐的 SMA 焊盘与回流工艺，遵循制造商的焊接温度曲线和湿度控制要求以保证可靠性。
- 在高频或高速差分线应用时，注意 TVS 的电容对信号完整性的影响，必要时选择低电容型号。
六、可靠性与选型提示
SMAJ10CA 在温度范围宽、漏电低且对 IEC 61000‑4‑2 有防护能力，适合大多数工业及民用防护需求。选型时除关注 Vrwm、Vc 与 Ipp 外，应确认工作环境温度、容许反复冲击次数以及线路的最大允许钳位电压，必要时与器件供应商确认器件在目标波形与能量下的寿命与退化特性。

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.
