SMAJ26CA/TR13 产品概述
一、产品简介
SMAJ26CA/TR13 为 Brightking（台湾君耀）出品的双向瞬态电压抑制器（TVS），采用 SMA（DO-214AC）封装，专为抑制瞬态过电压、保护敏感电子设备而设计。该器件在正负方向均能进行钳位动作，适用于交流或双向冲击场合以及需要双向浪涌保护的直流线路。
二、主要电气参数
- 极性：双向
- 反向截止电压 Vrwm：26 V（工作电压）
- 击穿电压（典型）：28.9 V
- 钳位电压 Vc（典型）：42.1 V（对应脉冲条件下）
- 峰值脉冲电流 Ipp：9.5 A
- 峰值脉冲功率 Ppp：400 W
- 反向电流 Ir：≤1 μA
- 类型：TVS（二极管）
以上参数表明器件在遭遇短时高能脉冲时能将过电压钳制在约42V 水平，同时在正常工作电压下漏电极小。
三、结构与封装
SMA（DO-214AC）小型表面贴装封装，适合自动贴片与回流焊工艺。TR13 后缀表示卷带包装（Tape & Reel），便于SMT生产线直接使用。封装尺寸紧凑，易于在空间受限的电路板上布置。
四、典型应用场景
- 24V 工业控制与通信设备的电源浪涌保护（如PLC、继电器驱动）
- 串行接口、通信总线的过压保护（RS‑485、CAN 总线等双向线路）
- 电源输入端、接口保护、充电系统与电机驱动控制板的防雷击及感性负载反激抑制
五、选型与使用建议
- 若系统工作电压接近 24–26V 且需双向保护，SMAJ26CA 是合适选择；若为单向直流线路则可考虑单向型 TVS。
- 布局时应尽量缩短被保护线路到 TVS 的走线长度，减小寄生电感；关键节点应与地/GND 做低阻连接以提升吸能效果。
- 根据实际浪涌能量和重复冲击频率，评估是否需要并联或选用更高 Ppp 等级的器件以提高可靠性。
六、可靠性与注意事项
- 器件适合用于短时脉冲抑制，不能替代持续过压保护（需配合熔断器或限流元件）。
- 长时间处于高频脉冲或接近极限功率条件下会加速老化，应预留足够余量。
- 回流焊接时遵循封装厂商的温度曲线及焊接工艺，避免过热造成封装或二极管损伤。
七、包装与采购
SMAJ26CA/TR13 为卷带包装，便于 SMT 自动化贴装。选购时请确认品牌（Brightking 台湾君耀）与器件型号，向供应商索取器件的完整规格书与试验曲线，以便在设计中准确使用。

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.
