SMAJ8.0A/TR13 产品概述
一、产品简介
SMAJ8.0A/TR13 是 Brightking（台湾君耀）出品的一款单向 TVS 二极管，封装为 SMA（DO-214AC）。该器件专为瞬态过电压和浪涌能量抑制设计，具有快速响应、高能量吸收能力和宽工作温度范围（-65℃ ~ +150℃），适用于各种直流电源线路与电子设备的浪涌保护。
二、主要电气参数
- 极性：单向（Unidirectional）
- 反向截止电压 Vrwm：8 V
- 击穿电压（典型）：8.89 V
- 钳位电压 Vc：13.6 V（在规定峰值脉冲条件下）
- 峰值脉冲电流 Ipp：29.4 A
- 峰值脉冲功率 Ppp：400 W（在典型脉冲测试条件下）
- 工作温度：-65℃ ~ +150℃
三、主要特性
- 高能量吸收能力，能在瞬态浪涌时钳位电压，保护下游电路免受过压损害。
- 单向结构，响应迅速，适合直流电源或具有明显极性的信号线路。
- SMA 封装（DO-214AC），适配常见的自动贴装工艺，占板面积小、散热性能良好。
- 宽温工作范围，适合工业级和恶劣环境应用。
四、典型应用场景
- DC 电源总线和分配线路保护（适用 Vrwm≈8V 的电源系统）
- 电池管理与充电接口的浪涌抑制
- 工业控制设备、电机驱动接口的瞬态保护
- 通信及网络设备的电源端保护
- 任何需要在有限封装中实现高能量抑制的电子系统
五、使用建议与布局要点
- 尽量将 TVS 器件置于受保护节点与接地之间，靠近受保护端口，减小 PCB 引线电感和走线长度。
- 对于需要吸收更高能量的场合，可并联多个器件或配合限流电阻/熔断元件使用，以分散能量并保护器件不被过载。
- 注意热量散发和焊接工艺，SMA 封装通过合理的铜箔面积有助于散热；回流焊参数应符合厂商推荐以避免热应力损伤。
- 在高可靠性应用中，结合合适的浪涌测试验证布局与实际保护效果。
六、封装与订购信息
- 封装：SMA（DO-214AC），表面贴装
- 品牌：Brightking（台湾君耀）
- 型号示例：SMAJ8.0A/TR13（请以供应商出货单为准）
总结：SMAJ8.0A/TR13 以其 400W 峰值脉冲功率与较低钳位特性，适合对 8V 级别电源与信号线进行高效瞬态保护。合理的 PCB 布局与配套电路能进一步提升系统抗冲击能力并延长器件寿命。若需在特定脉冲波形或更高能量条件下使用，请联系供应商获取完整测试曲线与可靠性数据。

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.
