SMAJ5.0CA-AT/TR13 产品概述
一、产品简介
SMAJ5.0CA-AT/TR13 为 Brightking（台湾君耀）出品的双向瞬态电压抑制二极管（TVS），采用 SMA（DO-214AC）低轮廓表面贴装封装，专为抑制瞬态过压而设计。器件采用玻璃钝化结工艺，具备低寄生电感与优良的钳位能力，适用于空间受限且要求高速响应的保护场合。
二、主要参数
- 极性：双向
- 反向截止电压 Vrwm：5.0 V
- 击穿电压 VBR（直流）：6.4 V
- 钳位电压（Ipp 下）：9.2 V
- 峰值脉冲电流 Ipp（10/1000μs）：43.5 A
- 峰值脉冲功率 Ppp（10/1000μs，重复率 0.01%）：400 W
- 反向泄漏电流 Ir：≤800 μA
- 工作温度范围：-55 ℃ ～ +150 ℃
- 封装：SMA (DO-214AC)，卷带供料（-AT/TR13）
三、关键特性说明
- 玻璃钝化结：提高热稳定性与长期可靠性，适合严苛环境。
- 低电感、低轮廓：对高频信号干扰影响小，适合高速接口与紧凑型电路板布局。
- 优秀钳位性能：在标准 10/1000μs 浪涌波形下可提供 400 W 峰值吸收能力，能有效限制电压峰值，保护后级器件。
- 双向保护：可同时抑制正向与反向瞬态，满足交流或可极性交换信号线路的防护需求。
四、典型应用场景
- I/O 接口保护（例如以太网端口、串行通信、USB 外围保护）
- AC/DC 电源输入和输出端浪涌保护
- 工业控制、消费电子、汽车电子的瞬态过压防护（在符合温度与环境规范下）
- 任何需在有限空间内实现高能量瞬态吸收的电路板设计
五、封装与安装注意
- 封装：SMA（DO-214AC），适合回流焊工艺，提供带卷带（TR13）包装，便于自动贴装。
- 布局建议：尽量将 TVS 靠近被保护端口或电源入口放置，最短、最粗的焊盘连接到需要保护的线路，以降低串联电感与提升响应速度。
- 热管理：在高能量吸收场合注意周边散热与 PCB 铜箔扩展，以提升重复浪涌承受能力。
六、可靠性与环境适应
- 工作温度范围宽（-55 ℃ 到 +150 ℃），适合多种工况。
- 低泄漏电流（≤800 μA）在 Vrwm 下有利于降低静态功耗，但在高温时泄漏会增加，应在系统热预算内评估。
七、选用与注意事项
- 确认所需保护电压与钳位电压要求一致：Vrwm 5 V，钳位约 9.2 V，适用于 5 V 系统保护。
- 对于多次高能量浪涌或更高脉冲电流需求，应评估是否需要更大功率等级或并联设计，并遵循厂商浪涌能力与热循环限制。
- 在汽车安全关键或极端环境应用中，建议参考厂商完整可靠性和 AEC 等级认证资料。
SMAJ5.0CA-AT/TR13 以其紧凑封装、良好钳位与高瞬态能量吸收能力，为 5 V 级别的接口与电源保护提供了一种经济、高效的解决方案。

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.
