1.5SMC39A/TR13 产品概述
一、概述
1.5SMC39A/TR13 为 Brightking（台湾君耀）推出的单向瞬态抑制二极管（TVS），采用 SMC 表面贴装低轮廓封装，专为保护电路免受雷击、浪涌及瞬态过压影响而设计。器件体积小、低电感、响应快，适合板上 I/O 接口与 AC/DC 电源等需抗浪涌保护的场合。
二、主要电气参数
- 极性：单向（unidirectional）
- 反向截止电压 Vrwm：33.3 V（最大持续工作电压）
- 击穿电压 VBR：37.1 V（典型/测试区间）
- 钳位电压 Vc：53.9 V（在指定脉冲电流下）
- 峰值脉冲电流 Ipp：28.2 A（10/1000 μs 波形）
- 峰值脉冲功率 Ppp：1.5 kW（10/1000 μs）
- 反向电流 Ir：1 μA（在 Vrwm 条件下）
以上参数表明该产品在 10/1000 μs 浪涌环境下具有良好的吸收能量能力与钳位效果。
三、产品特点
- 低轮廓 SMC 封装，优化电路板空间与自动贴装兼容性。
- 玻璃钝化结结构，提高结面稳定性与长期可靠性。
- 内置应力消除设计，提升机械应力与热循环下的可靠性。
- 低寄生电感与快速响应，适合高速信号线保护。
- 优异的钳位能力，在大电流冲击时能有效限制电压上升，保护后端器件。
四、典型应用
- 各类 I/O 接口（USB、串口、RJ45 等）过压保护。
- AC/DC 电源输入端的浪涌与瞬态防护。
- 工业控制、通信设备及基站等对浪涌耐受要求高的系统。
- 需要单向保护（直流供电场景）且对钳位电压有明确要求的线路。
五、封装与可靠性
SMC 封装提供良好的散热路径与机械强度，适合高能量吸收场合。玻璃钝化与内部应力消除结构使本件在温度循环、潮湿及振动环境下保持稳定性能。建议在高功率吸收场合配合合适的热沉或铜箔面积以便散热。
六、布局与使用建议
- 元件应尽量靠近被保护的输入端或接插件放置，减小导线长度以降低寄生电感。
- 将接地端通过短、粗的铜迹或多孔过孔与系统地平面连接，保证有效散热与回流路径。
- 对于长时间连续高能量冲击场景，考虑在 TVS 前串联限流元件（如保险丝或热敏电阻）以分担能量。
- 注意单向型适用于直流系统；在交流或需双向保护时应选用双向型号。
七、订购信息与替代建议
型号：1.5SMC39A/TR13，品牌：Brightking（台湾君耀），封装：SMC。订购时请确认供货包装（卷带/座盘）与后缀 /TR13 的交期与最小起订量。若需更高能量吸收或不同钳位，可按系统 Vrwm 与最大允许钳位选择相邻系列或咨询供应商推荐替代型号。
总结：1.5SMC39A/TR13 为一款面向板级防护的高能量单向 TVS 器件，适用于要求紧凑封装、快速响应与良好钳位能力的电源与接口保护应用。

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.
