SMAJ7.5CA/TR13 产品概述
一、产品概述
SMAJ7.5CA/TR13 为 Brightking（台湾君耀）出品的一款双向瞬态电压抑制器（TVS），封装为 SMA（DO-214AC）。器件针对短时高能量脉冲过压事件进行钳位保护，提供快速响应、低钳位电压的瞬态抑制，适用于各种需要稳压保护的电源和信号线路。
二、主要电气参数
- 反向截止电压（Vrwm）：7.5 V（器件在此电压下可长期工作）
- 击穿电压（Vz）：约 8.33 V（开始导通）
- 钳位电压（Vc）：12.9 V（在额定脉冲条件下的典型钳位电压）
- 峰值脉冲功率（Ppp）：400 W（在标准脉冲测试条件下）
- 峰值脉冲电流（Ipp）：31 A
- 反向漏电流（Ir）：100 μA（在 Vrwm 下典型值）
- 极性：双向（适合正负双向瞬态）
- 封装：SMA（DO-214AC）
三、产品特点
- 双向结构，可直接用于交流或可能出现极性反转的线路，安装简便。
- 低反向截止电压与较低钳位电压，有效降低被保护电路承受的瞬态电压应力。
- 400 W 峰值脉冲功率与 31 A 峰值冲击电流，能应对常见的开关瞬态、雷击感应脉冲等干扰源。
- 小型表面贴装封装（SMA），适配空间受限的商用与工业 PCB 设计。
四、典型应用场景
- 通用电源线与局部电源防护（如 5V/12V 辅助电源或接口的瞬态抑制）
- 通信设备、网络设备的端口防护
- 工业控制与信息设备的抗浪涌保护
- 电子模块、消费类电子中易受冲击的电源/信号节点
五、封装与安装建议
- SMA（DO-214AC）为常见表贴封装，焊盘设计应遵循厂家推荐的焊盘尺寸以保证散热与可靠焊接。
- 双向器件在 PCB 上无极性方向要求，但建议在靠近被保护端口与接地（或供电回路）位置就近布局，以降低寄生电感与提升抑制效果。
- 考虑到大脉冲能量释放，若应用中出现频繁高能冲击，应配合使用限流元件、浪涌吸收器（如气体放电管）或增加散热面积。
六、选型与使用注意事项
- 确认被保护电路的最大工作电压应低于 Vrwm（7.5 V），以避免常态下的泄漏或误动作。
- 若电路可能承受高于器件额定脉冲能量的浪涌，需级联更高能量的保护元件或采取防护体系。
- 注意焊接温度与回流曲线以避免封装损伤；存储与使用环境应避免超出厂家建议的温度与湿度范围。
- 对于特殊行业（如汽车、医疗等）请核实是否需满足对应的认证与可靠性测试要求。
总结：SMAJ7.5CA/TR13 是一款面向中等能量瞬态抑制场合的双向 TVS 器件，具有良好的钳位性能与小型化封装，适合在空间受限的电源与信号防护设计中使用。若需进一步的电流-电压曲线、脉冲测试条件或封装尺寸图，请参考厂商完整数据手册或联系供应商。

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.
