SMBJ33CA 产品概述
一、产品简介
SMBJ33CA 为双向瞬态电压抑制二极管（TVS），由扬杰（YANGJIE）生产，封装为 SMB（DO-214AA）。器件专为抑制瞬态过电压、保护敏感电子元件免受雷击、浪涌和静电放电（ESD）等冲击而设计，适用于直流和交流双向保护场合。
二、主要电气性能
- 极性：双向（双向对称抑制正、负极性瞬态脉冲）
- 反向稳态电压 Vrwm：33V（工作耐压）
- 击穿电压 Vbr：约 40.6V（典型值，按厂家测试条件）
- 钳位电压 Vc：约 53.3V（在规定冲击条件下）
- 峰值脉冲功率 Ppp：600W（10/1000μs 波形）
- 峰值脉冲电流 Ipp：约 11.3A（对应 600W 于 10/1000μs）
- 反向漏电流 Ir：≤5μA（在 Vrwm 条件下）
- 工作温度范围：-55℃ 至 +150℃
以上参数表明 SMBJ33CA 在 33V 级别系统中可提供高效的瞬态抑制能力，低漏电流有利于不影响正常电路工作。
三、封装与机械特性
器件采用 SMB（DO-214AA）表面贴装封装，便于自动贴装与高密度 PCB 布局。SMB 封装具有良好的热性能和机械强度，适合电源输入端、数据线路和通信接口等位置的保护方案。建议按厂商推荐的 PCB 焊盘和热沉处理布置焊盘，以保证散热及可靠连接。
四、典型应用场景
- 直流供电线路的浪涌与雷击保护（例如 24V/30V 系统）
- 串/并联电源输入防护、汽车电子非极性瞬态保护应用（需校核汽车规范时序）
- 工业控制设备、通信接口、开关电源及接口模块的 ESD 与浪涌抑制
- 需要双向保护的信号线和对称电源线路
五、使用建议与注意事项
- 在选择型号时确认系统静态电压低于 Vrwm（33V），并预留到 Vc 的充分裕量。
- 钳位电压 53.3V 为在规定脉冲条件下测得的典型值，实际钳位随冲击幅度和环境温度变化，请在系统级做能量分配验证。
- 为提高可靠性，可配合熔断器、限流电阻或电感使用，避免连续多次大幅冲击导致器件应力过大。
- 焊接时遵循无铅回流曲线和厂方推荐的温度/时间参数，避免超温影响器件性能。
- PCB 布局尽量缩短保护器件到被保护元件的连接长度，减小寄生电感。
六、可靠性与环境适应
器件工作温度范围宽（-55℃~+150℃），适应工业级和多数恶劣环境应用。低漏电流和高脉冲能量处理能力保证了长期稳定的保护性能。建议在极端环境或关键应用中做系统级浪涌测试以确认长期可靠性。
总结：SMBJ33CA 为一款面向 33V 等级系统的双向 TVS 器件，具有 600W 瞬态吸收能力、低漏电流和 SMB 便捷封装，适合工业、电源和通信等需要抗浪涌与 ESD 保护的场合。

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.
