SMDJ14A/TR13 产品概述
一、产品简介
SMDJ14A/TR13 是 Brightking（台湾君耀）推出的一款单向瞬态抑制二极管（TVS），采用 SMC (DO-214AB) 表面贴装封装，专为电路板空间优化与高能量浪涌保护设计。器件具有低轮廓、低电感和玻璃钝化结结构，适用于要求可靠浪涌保护的 I/O 接口和 AC/DC 电源线路。
二、主要电气参数
- 极性：单向
- 反向截止电压 Vrwm：14 V
- 击穿电压 VBR：15.6 V
- 钳位电压（Ipp 下）：23.2 V
- 峰值脉冲电流 Ipp：129.3 A
- 峰值脉冲功率 Ppp：3 kW
- 反向电流 Ir（在 Vrwm 下）：2 μA
- 工作温度范围：-55 ℃ ～ +150 ℃
（注：峰值脉冲功率与脉冲条件相关，应参考具体测试标准与应用波形。）
三、结构与特性亮点
- 低轮廓表面贴装封装，节约电路板空间并便于自动化组装；
- 玻璃钝化结提供出色的稳定性与长期可靠性；
- 内置应力消除设计，提高对热应力与焊接过程的耐受性；
- 低寄生电感，适合高速数据线与敏感模拟接口的瞬态抑制；
- 优异的钳位能力，在高能量脉冲下维持较低的钳位电压，保护后级器件。
四、典型应用场景
- 各类 I/O 接口保护（USB、以太网、串口等）；
- AC/DC 电源输入及辅路浪涌抑制；
- 工业控制、测量设备及汽车电子的局部浪涌防护（需按系统要求校核温度与能量）；
- 任何要求单向过压保护且空间受限的 PCB 设计。
五、选型与使用建议
- 选型时建议 Vrwm（14 V）略高于系统正常工作电压，以避免工作时出现持续击穿；
- 注意峰值脉冲电流 Ipp 与系统可能遭遇的浪涌能量匹配；若系统浪涌能量大于器件额定，请并联或选择更高能量等级器件，并在热管理上做好设计；
- 为发挥良好散热性能，应设计合适的铜箔面积与过孔（thermal vias），并遵循封装厂推荐的 PCB 封装焊盘与回流焊工艺；
- 单向器件在正向浪涌时表现类似整流二极管，应评估在极端事件下的正向电压与热应力。
六、可靠性与储存
- 工作温度范围宽（-55 ℃ ～ +150 ℃），适合多数工业级应用环境；
- 玻璃钝化结与内置应力消除提升长期可靠性；
- 存储与回流焊接应遵循供应商的包装与湿敏等级（MSL）建议，以避免吸湿后回流导致封装裂纹或焊点缺陷。
七、品牌与封装信息
- 品牌：Brightking（台湾君耀）
- 封装：SMC (DO-214AB)
- 型号示例：SMDJ14A/TR13
总结：SMDJ14A/TR13 是一款面向通用 I/O 与电源线路、具有高峰值吸收能力的单向 TVS，低轮廓、低电感及良好钳位特性使其在受空间与高速性能约束的设计中表现优异。选型时请结合系统最大浪涌能量、散热条件与工作电压余量进行核准。

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.
