SMBJ300CA 产品概述
一、产品简介
SMBJ300CA 为 RUILON（瑞隆源）出品的双向瞬态电压抑制器（TVS），采用 DO-214AA（SMB）封装，专为抑制瞬态过电压和浪涌能量而设计。该器件在脉冲冲击和静电放电条件下能提供稳定的保护性能，适用于工业、通信、电源等需要高能量抑制的场合。
二、主要参数
- 极性：双向
- 反向截止电压 Vrwm：300 V
- 击穿电压（典型）：371 V
- 钳位电压（典型）：486 V（按指定测试条件）
- 峰值脉冲电流 Ipp：1.3 A
- 峰值脉冲功率 Ppp：600 W（10/1000 μs 波形）
- 反向电流 Ir：1 μA（常温条件）
- 工作温度：-55 ℃ 至 +150 ℃
- 防护等级/标准：符合 IEC 61000-4-4（EFT）、IEC 61000-4-2（ESD）
三、产品特点
- 高能量吸收能力：在 10/1000 μs 波形下可承受 600 W 峰值脉冲功率，适合中低频浪涌抑制。
- 低漏电流：典型反向电流仅 1 μA，有利于降低待保护电路的静态功耗。
- 稳定钳位：典型钳位电压 486 V，可有效钳制超出工作范围的瞬态电压，保护下游器件安全。
- 宽温度范围：-55 ℃~+150 ℃，适合恶劣环境和工业级应用。
四、典型应用
- 工业控制设备和自动化系统的电源与信号线保护
- 通信设备、DSL、数据接口的过电压防护
- 电源模块、逆变器与光伏系统的浪涌抑制
- 消费电子与测试设备的输入/输出端口保护
五、封装与安装建议
SMBJ（DO-214AA）封装便于波峰或回流焊工艺组装。建议将器件尽可能靠近需保护的接口或器件布局，走线尽量短且粗，以降低感抗和提高散热性能。必要时在焊盘下方或附近增加铜箔和通孔以增强散热。
六、使用与注意事项
- 由于为双向 TVS，器件能对正负向瞬态均提供对称保护，安装时无需特别方向性要求。
- 长期运行在高功率脉冲下会导致温升和损耗，应遵循脉冲间隔与平均功率限制，避免连续超额冲击。
- 储存与装配过程中应注意防静电和湿度控制，遵循标准焊接温度曲线以保证可靠性。
七、可靠性与合规
SMBJ300CA 满足 IEC 61000-4-2（静电放电）与 IEC 61000-4-4（快速瞬变脉冲群）等级要求，适用于需要电磁兼容保护的设计。器件的高温工作能力和低漏电特性提升了在严苛环境下的长期可靠性。
八、订购信息与替代型号
品牌：RUILON（瑞隆源），型号：SMBJ300CA，封装：DO-214AA（SMB）。选型时请确认钳位电压、峰值功率及工作环境温度满足系统要求。若需更高能量或不同电压等级，可参考同系列其他规格或联系供应商获取样片与技术支持。

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.
