SMAJ18CA-AT/TR13 产品概述
一、概述
SMAJ18CA-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）表面贴装封装。器件设计用于对抗雷击、静电及电路瞬态过压，特别适合I/O接口与AC/DC电源线的过压保护。器件具有低轮廓、低电感与玻璃钝化结结构，确保在高速与高重复冲击条件下稳定工作。
二、主要规格
- 极性：双向
- 反向截止电压 Vrwm：18 V
- 击穿电压 VBR：20 V
- 钳位电压（Ipp=13.7 A）：29.2 V
- 峰值脉冲电流 Ipp：13.7 A
- 峰值脉冲功率 Ppp（10/1000 μs，重复率0.01%）：400 W
- 反向电流 Ir：≤1 μA
- 工作温度：-55 ℃ 至 +150 ℃
- 封装：SMA（DO-214AC）
三、产品特性
SMAJ18CA 提供出色的钳位能力与低漏电流，适用于要求高可靠性与低功耗的设计。玻璃钝化结带来优良的长期稳定性，低电感特性使其能兼容高速信号线的保护需求。SMD 封装利于节省电路板空间并支持自动化贴装。
四、应用场景
- 串行/并行 I/O 接口保护（USB、RS-485、CAN 等）
- AC/DC 电源输入浪涌保护
- 工业控制、通讯设备、自动化终端与消费电子等需抗浪涌与静电的场合
五、典型布局与安装建议
为获得最佳抑制效果，推荐将 TVS 器件靠近被保护端口布置，连接走线最短且对称。小尺寸铜迹与多层地平面结合散热孔可提升脉冲能量承受度。建议在回流焊工艺中遵循元件厂商的温度曲线并采取防潮处理。
六、可靠性与使用注意
器件能在-55 ℃ 至 +150 ℃范围内工作，适应苛刻环境。长期存储请避光、防潮并遵循防静电操作规范。虽然器件能承受短时大功率脉冲，但不应作为持续过压情况下的替代方案，设计时应配合适当的限流或熔断保护。
七、订购与品牌保障
型号：SMAJ18CA-AT/TR13，封装SMA，常见为卷带（TR）包装以支持贴片生产线。Brightking（台湾君耀）提供稳定的质量管控与技术支持，适合批量生产与工业级应用。购买时请确认规格表与原厂批次以确保器件性能一致。

Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
