SMBJ26A（BORN 伯恩）TVS二极管产品概述
一、产品简介
SMBJ26A 是 BORN（伯恩半导体）出品的一款单向瞬态抑制二极管（TVS），封装为 DO-214AA（SMB），主要用于对直流电源线、数据线和接口的静电放电与浪涌冲击保护。该器件按 10/1000µs 浪涌波形标定，能够在突发高能量浪涌下迅速钳位，保护后级电路元件不被过压损坏。
二、主要电气参数
- 反向稳态电压 Vrwm：26 V（建议工作电压不超过此值）
- 击穿电压（Vbr）：31.9 V（典型）
- 钳位电压（Vc）：42.1 V（标定于 10/1000µs 浪涌条件下）
- 峰值脉冲功率 Ppp：600 W（10/1000µs）
- 峰值脉冲电流 Ipp：14.3 A（10/1000µs）
- 反向漏电流 Ir：1 µA（在 Vrwm 条件下，典型）
- 极性：单向（适用于直流或有方向性的电压线）
- 类型：TVS（瞬态抑制 / ESD 抗扰）
- 封装：DO-214AA （SMB，表面贴装）
三、性能亮点
- 大功率承受能力：600 W 的峰值脉冲功率能够吸收工业、通信和电源线路上出现的高能量浪涌（如雷击感应或开关冲击）。
- 低漏电：1 µA 的低反向漏电有利于不影响电源的静态功耗，适合对静态能耗敏感的电路。
- 快速响应：作为 TVS 器件，具有很快的响应时间，可在纳秒级别钳制瞬态过压。
- 适用于 24 V 级系统：Vrwm=26 V 表明其适配 24 V 工作电压的系统保护需求。
四、典型应用场景
- 工业控制与自动化的 24 V 电源总线防护
- 通信设备电源和接口保护（例如以太网供电、远端供电）
- 电源模块、逆变器与配电板的浪涌防护
- 需要抗雷击感应、开关瞬态抑制的场合
五、设计与使用建议
- 选型时将 Vrwm 稍高于正常工作电压，保证在正常工作下无触发；同时确认钳位电压低于被保护器件的最大承受电压。
- 布局建议：TVS 尽量靠近被保护的接口或电源输入端，走短而宽的引线连接到地线，以降低串联电感和提高散热能力。
- 热管理与功率余量：在可能出现多次或更长波形的冲击时，应考虑器件的热耗散能力和必要的冗余；对于频繁冲击场合，选用更高能量等级或并联/级联方案。
- 极性注意：本器件为单向 TVS，不适用于没有固定极性的交流线路或需要双向保护的场合，双向保护请选用相应型号（双向/双极性）器件。
六、封装与可靠性
SMBJ 封装适合表面贴装工艺（SMT），便于自动贴装与回流焊。适用于工业级环境，但在恶劣环境（高温、高湿或腐蚀性气氛）使用时，应结合电路板防护措施（如涂覆、密封）与厂家的环境可靠性数据一并评估。
结语：SMBJ26A（BORN）是一款针对 24 V 级及类似应用设计的高能量单向 TVS，具有高吸收能量、低漏电和快速钳位的优点。在实际设计中，合理的版面布局与选型配合能充分发挥其保护效果。

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.
