SMAJ26A/TR13 产品概述
一、产品简介
SMAJ26A/TR13 是台湾君耀（Brightking）推出的一款单向瞬态电压抑制器（TVS），采用SMA（DO-214AC）封装，专为抑制瞬态过压（如雷击、电源浪涌、电感反冲等）设计。器件在瞬态冲击时提供低阻抗通路，将能量安全钳位到有限电压值，从而保护敏感电子元件和电路。
二、主要电气参数
- 反向截止电压 Vrwm：26 V（工作稳压电压）
- 击穿电压（Vbr）：28.9 V（典型）
- 钳位电压（Vc @ Ipp）：42.1 V
- 峰值脉冲功率 Ppp：400 W（8/20μs 波形参考）
- 峰值脉冲电流 Ipp：9.5 A（对应钳位电压）
- 反向漏电流 Ir：1 μA（典型，在 Vrwm 下）
- 极性：单向（适用于直流正向保护）
- 类型：TVS 二极管
三、特性与优势
- 高能量吸收：400W 的短时能量吸收能力，适合工业级浪涌防护。
- 低钳位电压：在 9.5A 冲击电流下钳位于 42.1V，可有效降低受保护节点的过压应力。
- 低漏电流：1 μA 的低静态漏电特性，适合需低待机功耗的系统。
- 小型封装：SMA 封装兼顾散热与空间，占板面积小，便于 SMT 自动贴装。
- 单向结构：对直流电源轨（如 24V 系统）提供可靠保护。
四、典型应用场景
- 工业控制与自动化设备的 24V/26V 电源防护；
- 通信设备、端口保护（如串口、电源输入端）；
- 电源模块、逆变器、驱动器的瞬态浪涌抑制；
- 汽车电子（非高压总线）及其他对瞬态耐受性要求较高的场合。
五、封装、可靠性与使用注意
- 封装：SMA（DO-214AC），/TR13 表示卷带包装，适合 SMT 回流焊制程与自动贴装。
- 热设计：虽然为瞬态脉冲器件，但长时间或重复高能量冲击会导致热积累。建议设计足够的 PCB 散热铜箔和热流通路，避免在靠近热源位置封装。
- 安装位置：尽量靠近被保护引脚或电源输入端放置，缩短导线/走线长度以降低串联感抗。
- 方向：单向器件需正确极性安装（阴极接正极电源侧或按电路要求），反向接入会改变保护特性。
六、选型建议与订购信息
- 选型原则：工作电压 Vrwm 应略高于系统正常工作电压（例如 24V 系统可选 26V Vrwm）；注意钳位电压需低于被保护器件的最大耐压。
- 订购：型号 SMAJ26A/TR13，品牌 Brightking（台湾君耀），/TR13 为卷带包装（适合批量 SMT 贴装）。如需样片或更多可靠性、封装尺寸、波形测试数据，请向供应商索取详细规格书（Datasheet）并在实际设计中参考冲击波形（例如 8/20μs）和环境温度下的性能曲线。

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.
