SMAJ6.5A/TR13 产品概述
一、产品简介
SMAJ6.5A/TR13 为 Brightking（台湾君耀）出品的单向瞬态电压抑制二极管（TVS），封装为 SMA (DO-214AC)。该器件专为吸收瞬态过电压脉冲设计，保护敏感电子元件免受浪涌、电快速瞬变和静电放电的损害。其反向截止电压（Vrwm）为 6.5V，钳位电压约 11.2V，击穿电压约 7.22V，适合 5V 及类似电压等级的线路保护。
二、主要电气参数
- 极性：单向（用于正向保护场合）
- 反向截止电压 Vrwm：6.5V
- 击穿电压 Vbr：7.22V
- 钳位电压 Vc：11.2V（峰值脉冲时）
- 峰值脉冲电流 Ipp：35.7A
- 峰值脉冲功率 Ppp：400W（标准脉冲条件下）
- 反向漏电流 Ir：500µA
- 工作结温范围：-65°C ～ +150°C
三、关键特性与优势
- 高冲击吸收能力：单次脉冲峰值功率 400W，能有效吸收突发浪涌能量。
- 低钳位电压：在大电流时仍可将被保护电路电压限制在安全范围内，减少元件应力。
- 宽工作温度：适用于工业级及汽车周边环境（耐高低温）。
- SMA 紧凑封装：便于表面贴装、体积小且散热性能良好，利于自动化贴片生产。
四、典型应用场景
- 电源总线与数据总线过压保护（如 +5V 系统、通信接口）
- 工业控制设备、电源模块、开关电源输入端防护
- 消费电子、网络设备和外围接口的浪涌防护
- 汽车电子辅助保护（需参考汽车级规范与温度应力）
五、布局与使用建议
- 尽量将 TVS 靠近被保护端口或器件布置，以减小寄生电感和走线阻抗。
- 使用宽短走线或增加铜箔面积以提高散热能力和脉冲承受能力。
- 单向器件安装时注意极性，阴极端通常标识条纹并接地或负极。
- 对于长期漏电流敏感的应用，需评估 500µA 的反向漏电对系统的影响。
- 焊接时遵循封装耐温规范，避免超过制造商推荐的回流温度曲线。
六、选型与注意事项
选择时确认系统最大工作电压 ≤ Vrwm（6.5V），并预留安全余量；若系统可能出现更大脉冲或多次重复冲击，应考虑更高功率等级或并联、组合防护方案。文档型号：SMAJ6.5A/TR13，品牌 Brightking（台湾君耀），封装 SMA (DO-214AC)。

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.
