SMBJ5.0A 产品概述
一、概述
SMBJ5.0A 是乐山无线电（LRC）提供的一款双向瞬态抑制二极管（TVS），采用SMB（DO-214AA）表贴封装。器件针对工业级瞬态浪涌保护设计，可在脉冲冲击条件下快速钳位电压，保护下游敏感电路免受过压损伤，适用于多种直流和交流系统的浪涌抑制。
二、主要性能参数
- 极性：双向（Bidirectional）
- 反向截止电压 Vrwm：5 V
- 击穿电压 Vbr：7 V（典型）
- 钳位电压 Vc：9.2 V（Ipp 条件下）
- 峰值脉冲电流 Ipp：65.3 A（1 ms 波形）
- 峰值脉冲功率 Ppp：600 W（1 ms）
- 反向电流 Ir：800 µA（在 Vrwm 条件下）
- 工作温度范围：-55 ℃ ~ +150 ℃
- 封装：SMB（DO-214AA）
- 类型：TVS 二极管，品牌：LRC（乐山无线电）
三、产品特点
- 双向结构可对称抑制正负瞬态脉冲，适合交流和双向保护场合；
- 高频响应、响应时间极短，有效截断快速上升的浪涌尖峰；
- 在 1 ms 能承受 600 W 的脉冲能量，钳位电压低（9.2 V），减小被保护电路应力；
- 宽温度范围及工业级耐热性能，适合严苛工作环境；
- SMB 表贴封装便于自动化贴装与散热、安装可靠。
四、典型应用
- 电源输入端浪涌保护（5 V 电源、USB、串口等）；
- 工业控制设备、通讯基站、安防设备的过压保护；
- 电池管理、逆变器输入端的瞬态抑制；
- 汽车电子（非车规环境）及消费电子的接口保护。
五、选型与使用建议
- 若保护 5 V 供电线路，SMBJ5.0A 的 Vrwm=5 V 与低钳位特性是合适选择；
- 注意反向漏电 Ir 为 800 µA，在对静态功耗敏感的设计需评估漏电影响；
- PCB 布局应将 TVS 靠近受保护端口并尽量减小引线电感，以保证钳位效果；
- 对于更高能量或更严苛冲击需求，可并联或选用更大封装的 TVS 解决方案，但并联需匹配温漂与参数。
六、安装与可靠性注意事项
- SMT 贴装后应进行推荐的回流焊温度曲线，避免超过器件最高结温；
- 长期工作在靠近极限温度或高泄漏条件下可能影响寿命，建议做热仿真与实际环境评估；
- 储存与运输应避免潮湿与机械冲击，遵循器件出厂防潮规范。
SMBJ5.0A 以其实用的钳位电压、足够的脉冲承受能力和成熟的 SMB 封装，适合用于保护 5 V 级别的电源与接口，是性价比较高的瞬态抑制元件选择。若需更详细的电气曲线或封装尺寸图，可参考 LRC 提供的器件 datasheet。

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.
