SMBJ75CA/TR13 产品概述
一、产品简介
SMBJ75CA/TR13 是 Brightking(台湾君耀) 生产的一款 SMB 封装（DO-214AA）双向瞬态抑制二极管（TVS）。该器件设计用于在电源与信号线发生瞬态过压时提供快速夹位保护，典型参数包括工作反向截止电压 Vrwm = 75V、击穿电压 Vbr ≈ 83.3V、钳位电压 Vc ≈ 121V，峰值脉冲功率 Ppp = 600W、峰值脉冲电流 Ipp = 5A，反向漏电流 Ir ≤ 1μA。
二、主要特点
- 双向（Bidirectional）结构，适用于交流或双向瞬态脉冲保护。
- 高能量吸收能力：600W 峰值脉冲功率（在规定脉冲波形下），可承受电压冲击。
- 低钳位电压：在发生过压时将电压钳制于较低水平，保护后级元件。
- 小封装、高可靠性：SMB 封装便于表面贴装，适合自动化生产。
- 低漏电流：Ir ≤ 1μA，有利于低功耗或高阻电路的长期稳定性。
三、典型应用场景
- 工业电源与控制设备中的浪涌保护（如直流或中低压配电线路）。
- 通信与监控设备的输送线、接口保护。
- 开关电源、逆变器输入端的过压抑制。
- 电机驱动、汽车电子（需确认车规级要求）等对双向浪涌敏感的场合。
四、选型与使用建议
- 若保护对象为直流单向电路，可优先考虑单向 TVS；本型号适合需双向保护的 AC 或可能反向冲击的系统。
- 峰值脉冲电流 Ipp=5A 以及 Ppp=600W 是在标准脉冲条件下的指标，实际系统中请评估脉冲能量与波形，必要时采用并联或更高额定能量的器件。
- 布局时应尽量缩短保护器件与被保护端之间的走线，设置短粗地线以降低感抗和钳位电压。
- 可配合熔断器、限流电阻和良好接地以提高整体防护效果与重复击穿能力。
五、封装与采购信息
- 封装：SMB（DO-214AA），适合回流焊工艺。
- 标识：SMBJ75CA/TR13，TR13 常表示卷带（Tape & Reel）包装，便于 SMT 自动贴装。
- 品牌：Brightking（台湾君耀）。
六、可靠性与注意事项
- 在高速脉冲环境下反复被击会影响寿命，建议根据冲击频率评估器件更换周期。
- 存储与焊接应遵循制造商的湿度敏感等级（MSL）与回流温度曲线，避免因热应力或潮湿引发焊接缺陷。
- 选型时核对工作温度范围和应用是否需车规级或其它认证。

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.
