SMBJ30CA 产品概述（YANGJIE 扬杰）
一、产品简介
SMBJ30CA 是扬杰（YANGJIE）生产的一款双向瞬态电压抑制器（TVS），采用 SMB（DO-214AA）封装，专为瞬态过电压和静电放电（ESD）保护设计。该器件在直流或交流工作环境中均能快速钳位浪涌电压，保护后端电子元件免受瞬态高能冲击。
二、主要特性
- 钳位电压（Vc）：48.4V（在规定脉冲条件下测得），有效抑制浪涌峰值，保护电路安全。
- 击穿电压（Vbr）：33.3V，为器件进入导通的起始电压范围。
- 反向截止电压（Vrwm）：30V，适用于 24V/30V 等直流供电系统的稳态保护。
- 峰值脉冲功率（Ppp）：600W（单次脉冲能力），用于吸收短时高能浪涌。
- 峰值脉冲电流（Ipp）：12.4A（对应钳位条件），表明在指定脉冲下的最大承受电流能力。
- 反向泄漏电流（Ir）：5µA（在 Vrwm 条件下），静态漏电小，不影响正常工作。
- 极性：双向（Bidirectional），对正负极性浪涌均能有效抑制。
三、典型应用
- 汽车电子（车载 12V/24V 总线的浪涌和瞬态保护）
- 电源输入与稳压模块保护（开关电源、充电器等）
- 工业控制设备、通信接口、传感器供电线路
- 消费电子设备的接口和外设保护（防止静电和线路浪涌）
四、使用建议与安装要点
- 布局上应将 SMBJ30CA 尽量靠近被保护节点（如电源输入端或接口引脚）焊接，缩短导线长度以减小寄生电感。
- 对于双向型号，无需区分正负极，适合交流或反向脉冲场合。
- 注意该器件的 600W 为脉冲功率等级，不能作为持续导通元件长期承受大电流；需与限流元件（熔断器、PTC、阻抗）配合使用以提高系统可靠性。
- PCB 走线应留意散热路径，必要时增加过孔或铜箔以帮助热量扩散。
五、可靠性与封装信息
- 封装：SMB (DO-214AA)，便于表面贴装与自动化生产，适合批量装配。
- 品牌：YANGJIE（扬杰），专业半导体制造，提供稳定的品质控制与出厂测试。
- 器件在正常规格内工作时泄漏电流低（Ir≈5µA），有利于低功耗系统的长期运行。
六、选型小结
SMBJ30CA 适合需要 30V 级稳态耐压并能承受高能短时浪涌的保护场合，双向特性使其在交流或可反向出现高压脉冲的电路中更易集成。选用时请确认系统最大工作电压不超过 Vrwm（30V），并根据系统可能遭受的浪涌能量与施加保护的拓扑配合相应的限流与热管理方案，以确保长期可靠性。

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.
