SMDJ45CA/TR13 产品概述
一、概述
SMDJ45CA/TR13 是 Brightking（台湾君耀）推出的一款双向瞬态电压抑制器（TVS），采用 SMC（DO-214AB）表面贴装封装，专为保护敏感电子电路免受瞬态过压冲击而设计。器件具有低外形、低电感与玻璃钝化结结构，兼顾空间优化与可靠性，适用于 I/O 接口及 AC/DC 电源等多种场合。
二、主要电气参数
- 极性：双向
- 反向截止电压 Vrwm：45 V
- 击穿电压 VBR：50 V
- 钳位电压（典型）：72.7 V
- 峰值脉冲电流 Ipp：約 68.8 A（10/1000 μs）
- 峰值脉冲功率 Ppp：5 kW（10/1000 μs）
- 反向漏电流 Ir：2 μA（典型）
- 工作温度范围：-55 ℃ ~ +150 ℃
- 封装：SMC（DO-214AB）
- 类型：瞬态抑制二极管（TVS），表面贴装
三、产品特点
- 表面贴装设计：适配自动化贴装与回流焊工艺，节省电路板空间。
- 低外形与低电感：减小寄生电感，提高对高能瞬态的响应速度和抑制效果。
- 玻璃钝化结与内置应力消除：提高结可靠性与热机械稳定性，延长使用寿命。
- 出色的钳位能力与高峰值功率承受能力：在 10/1000 μs 冲击下可承受高达 5 kW 的瞬态能量，适合高能浪涌环境。
- 极低漏电流：2 μA 等级，减少对电路静态性能的影响。
四、典型应用
- 各类 I/O 接口保护（通信接口、USB、串行总线等）。
- AC/DC 电源端口的浪涌保护与抑制。
- 工业控制、基站设备、汽车电子（非车规版本需确认）、消费电子等需要高能量瞬变防护的系统。
五、设计与布局注意事项
- 放置位置：尽量靠近被保护的受害器件或接口端口以缩短能量回路。
- 布线要求：焊盘与走线要尽量短、宽，避免长回流路径引入额外电感，必要时使用多箔层铜埋或过孔增加散热。
- 热管理：在高能量抑制场景下，注意 PCB 散热设计与周边元件热敏性。
- 选型确认：双向器件适用于交流或双向冲击场景；若仅单向保护，请选择相应单向型号。
- 测试与可靠性：在目标应用中进行浪涌测试以验证实际钳位与功率承受能力，注意长期工作环境温度对器件特性的影响。
六、包装与订购信息
- 品牌：Brightking（台湾君耀）
- 型号：SMDJ45CA/TR13（表面贴装，SMC 封装）
- 订购时请确认数量、包装卷带规格与锡膏/回流工艺兼容性，并在使用前参照厂家数据手册获得完整的电气、机械与焊接规范。
如需器件完整规格表、浪涌波形下的典型伏安曲线或在特定应用中的布局示意图，可提供进一步资料或引用官方数据手册以便精准设计。

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.
