SMBJ75A/TR13 产品概述
一、概述
SMBJ75A/TR13 是 Brightking（台湾君耀）出品的一款单向瞬态电压抑制二极管（TVS），封装为 SMB（DO-214AA）。器件为单向结构，专为抑制开关瞬变、电源浪涌和雷击脉冲等过压事件设计，适用于中高电压母线和工业级保护场合。
二、主要电气参数
- 极性：单向
- 反向工作电压（Vrwm）：75 V
- 击穿电压（Vbr）：83.3 V（标称）
- 钳位电压（Vc）：121 V（在峰值脉冲电流 Ipp 下）
- 峰值脉冲电流（Ipp）：5 A
- 峰值脉冲功率（Ppp）：600 W（典型按标准脉冲波形测得，如 10/1000 μs）
- 反向漏电流（Ir）：1 μA（在 Vrwm 条件下）
- 类型：TVS（瞬态电压抑制器）
- 封装：SMB（DO-214AA）
三、典型应用场景
- 48V及以下工业电源母线防护
- 通信基站、电源模块与开关电源的输入端浪涌抑制
- 工业控制设备、PLC、驱动器等的电源瞬态保护
- 电池管理与储能系统对突发电压的保护（须按系统要求评估）
四、使用与布局建议
- 建议将 TVS 放置在被保护器件与外部连线之间的最靠近入口处，以缩短引线长度，降低感性耦合。
- SMB 封装需配合相应 PCB 焊盘设计并保证良好散热通道；对于频繁脉冲或高能量的应用，考虑加大铜箔面积或连接至散热层。
- 峰值功率按标准脉冲波形给出，实际应用中应避免重复超额脉冲并留足安全裕量。
五、可靠性与注意事项
- 反向漏电在 Vrwm 下为 1 μA，适合对漏电敏感的电路。
- 在高能量脉冲后应检查器件状况：若出现参数漂移或漏电增加，应更换以确保系统可靠性。
- 推荐遵循标准的回流焊温度曲线进行封装焊接，避免过热导致器件损伤。处理时注意静电防护与清洁，避免焊剂残留影响长期可靠性。
六、选型与订购信息
型号：SMBJ75A/TR13，品牌：Brightking（台湾君耀），封装：SMB（DO-214AA）。在选型时请参考实际峰值脉冲能量、重复冲击频率与工作环境温度，必要时与供应商确认详细试验曲线与样品验证方案。

Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
