5.0SMDJ26CA 产品概述
一、产品简介
5.0SMDJ26CA 是 BORN（伯恩半导体）推出的一款双向 TVS（瞬态电压抑制）二极管，面向电源端口的浪涌保护设计。其典型工作电压（Vrwm）为 26V，具备高能量吸收能力与低钳位电压，适合保护 24V 级电源、工业电源输入、充电口等对瞬态过压敏感的场合。
二、主要电气参数
- 极性：双向
- 反向截止电压 Vrwm：26V
- 击穿电压 VBR（典型）：31.9V
- 钳位电压 Vc：42.1V（对应峰值脉冲条件）
- 峰值脉冲电流 Ipp：119A @ 10/1000μs
- 峰值脉冲功率 Ppp：5kW @ 10/1000μs（Vc × Ipp ≈ 42.1V × 119A ≈ 5kW）
- 反向漏电流 Ir：≤5μA（在 Vrwm 条件下）
- 类型：TVS 浪涌保护器件
三、关键特性与优势
- 高能量吸收：10/1000μs 波形下可承受 119A 峰值脉冲，功率约 5kW，能有效吸收雷击、开关瞬变等高能脉冲。
- 低漏电：Vrwm 下漏电小于 5μA，有利于低功耗系统与电池供电设备。
- 双向保护：对正负极对称钳位，适合交流或双极性瞬态场景。
- 可靠封装：DO-214AB（SMA）封装兼顾散热与焊接强度，适用于表面贴装生产线。
四、典型应用场景
- 工业控制电源输入（24V 系统）
- 通信设备电源接口、充电口过压保护
- 逆变器、太阳能逆变系统的端子防护（瞬态雷击）
- 汽车电子低压配电总线（选型需考虑汽车规范）
- 电源适配器、开关电源输出防护
五、封装与热管理
5.0SMDJ26CA 采用 DO-214AB（SMA）表面贴装封装，尺寸稳定，便于波峰或回流焊。由于浪涌能量转化为热量，建议在布局时为器件提供良好的散热路径：增加焊盘铜厚、在底层布热铜或开设散热通孔（vias），并避免长期连续承受过压事件。
六、布板与安装建议
- 尽量将 TVS 靠近被保护的接口或连接器，缩短引线长度以减小寄生感抗。
- 使用宽铜迹并与地（或公共参考）形成低阻抗回路。
- 与熔丝或限流元件配合使用，以防在大能量冲击下器件进入持续导通造成系统损坏。
- 遵循制造商推荐的回流焊曲线，避免过热影响可靠性。
七、选型与可靠性
选型时确认系统最大工作电压应低于 Vrwm（26V），且钳位电压（42.1V）在被保护电路可接受范围内。注意 TVS 适用于吸收短脉冲能量，不宜作为长时间过压的替代方案。建议在设计中参考相关浪涌/雷击测试标准并进行样机验证。
八、订购信息与注意事项
品牌：BORN（伯恩半导体）；封装：DO-214AB（SMA）。在订购与使用时，核对完整型号、封装与规格参数，保存器件防潮包装并按 ESD 要求操作。若需用于汽车级或高可靠性场合，请向供应商确认是否满足相应认证与额外测试报告。

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.
