SMBJ51CA/TR13 产品概述
一、产品简介
SMBJ51CA/TR13 为 Brightking（台湾君耀）出品的双向瞬态电压抑制二极管（TVS），封装为 SMB（DO-214AA）。器件专为瞬态过压、浪涌和静电放电等瞬时脉冲干扰提供钳位保护而设计，具有高峰值脉冲功率能力与低反向漏电流，适用于工业电源、通讯接口以及一般电气线路的浪涌保护。
二、主要电气参数
- 类型：双向 TVS
- 反向截止电压 Vrwm：51 V
- 击穿电压（典型）：56.7 V
- 钳位电压（典型）：82.4 V（在指定测试条件下）
- 峰值脉冲功率 Ppp：600 W（10/1000 μs 波形或厂家指定条件）
- 峰值脉冲电流 Ipp：7.3 A
- 反向漏电流 Ir：1 μA（在 Vrwm 条件下）
- 极性：双向（适合交流或双极性瞬态）
- 封装：SMB（DO-214AA）
三、性能亮点
- 高能量吸收：600 W 的峰值脉冲功率，可在短时浪涌下有效钳位，降低下游元件应力。
- 低漏电：1 μA 级别反向电流，有利于保持系统静态功耗低。
- 双向保护：对正负极瞬态均可快速响应，适合交流线路或双向信号保护场合。
- SMB 封装：兼顾装配可靠性与散热性能，适合自动贴片或手工焊接应用。
四、典型应用场景
- 开关电源输入端和输出端的浪涌保护
- 通信接口（例如以太网、信号线）防雷/浪涌抑制
- 工业控制设备、电机驱动器的瞬态抑制
- 消费类与网络设备的输入保护（需注意是否符合特定行业认证要求）
五、使用建议与注意事项
- 布局：将 TVS 器件尽量靠近需保护的端口或连接器，减小寄生电感与回路长度。
- 配合元件：在高能量场合建议与熔断器、限流电阻或放电器件配合使用，避免器件因反复高能冲击而损坏。
- 热管理：长期或重复脉冲条件下注意能量累积与封装升温，必要时改善 PCB 散热或选择更高功率等级产品。
- 焊接：遵循 SMB 封装的焊接曲线与回流规范，避免超过推荐温度和时长引起封装或电性能退化。
- 规格确认：在特定应用中请参考厂商完整数据手册与波形/测试条件，确认钳位电压、脉冲波形（10/1000μs、8/20μs等）与能量容量是否满足需求。
六、订购信息
- 品名：SMBJ51CA/TR13
- 品牌：Brightking（台湾君耀）
- 封装：SMB（DO-214AA）
- 适合需要双向瞬态保护且工作电压接近 51 V 的应用场合。购买或设计前建议索取并阅读原厂数据手册，以便验证所有极限值与测试条件。

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.
