SMCJ5.0A/TR13 产品概述
一、产品简介
SMCJ5.0A/TR13 是台湾君耀（Brightking）出品的一款单向 TVS 晶体管（二极管）瞬态抑制器，采用 SMC (DO-214AB) 封装。器件针对瞬态过压、雷击浪涌和静电放电等电磁脉冲事件提供高能量吸收能力，适用于需要对 5V 直流总线或信号线进行稳健保护的工业、通信和消费类电子设备。
二、主要电气参数
- 极性：单向
- 反向截止电压 Vrwm：5V（适配典型 5V 体系）
- 击穿电压（Vbr）：6.4V
- 峰值钳位电压（在 Ipp 下）：9.2V
- 峰值脉冲电流 Ipp：163A（10/1000μs 脉冲）
- 峰值脉冲功率 Ppp：1.5kW @ 10/1000μs
- 反向漏电流 Ir：1μA（典型、在 Vrwm 条件下）
- 工作温度范围：-65℃ ~ +150℃
以上参数表明 SMCJ5.0A 在 5V 系统发生大型浪涌事件时，能够在规定的电流下将被保护节点电压钳至较安全水平，有效保护下游电路元件。
三、封装与合规
- 封装：SMC (DO-214AB)，适合自动贴片生产与手工焊接并具备较高的热耗散能力
- 包装形式：TR13（卷带，适用于贴片机上料）
- 防护等级：符合 IEC 61000-4-2 静电放电防护要求（用于 ESD 抗扰度设计）
四、应用场景
- 5V 电源总线过压保护（开关电源输出、USB VBUS、单片机供电）
- 工业控制与现场 I/O 保护（继电器驱动、电机控制接口）
- 通信设备与电信接入设备的电源/信号保护
- 电动工具与汽车电子对瞬态浪涌的局部保护（需结合系统级设计考虑）
五、设计与使用建议
- 放置位置：将器件尽量靠近信号/电源进入点或需要保护的器件，缩短走线以降低寄生电感。
- 接地要求：为取得最佳保护效果，器件负极应可靠接地或接到系统参考地，保证快速、低阻抗回流路径。
- 封装焊接：SMC 封装需按制造商推荐的回流温度曲线焊接，避免超温或过长加热时间以保护封装性能。
- 热管理：在频繁或高能量浪涌场合，注意 PCB 铜箔面积和散热路径，必要时增加热沉或散热铜层。
- 与其他保护一起使用：对于高速数据线可配合小电容、共模电感或低电容 TVS，以兼顾信号完整性与保护性能。
六、产品优势与注意事项
优势：高能量吸收（1.5kW@10/1000μs）、高峰值脉冲电流能力（163A）、低反向漏电（1μA）和宽工作温度范围，使其在严苛环境下具有可靠的浪涌与 ESD 抑制能力。
注意事项：器件为单向设计，应匹配系统极性；选择与实际系统电压和允许钳位电压相协调的型号，避免频繁触发造成寿命退化。
如需器件封装尺寸图、典型钳位曲线或在特定工况下的仿真数据，可提供进一步支持与样品测试建议。

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.
