SMDJ24CA/TR13 产品概述
一、概述
SMDJ24CA/TR13 是 Brightking（台湾君耀）推出的一款双向瞬态抑制二极管（TVS），采用SMC (DO-214AB) 表面贴装封装，专为保护 I/O 接口和 AC/DC 电源线路免受突发浪涌和瞬态过压冲击而设计。器件具有低轮廓、低电感和玻璃钝化结结构，能够在有限的电路板空间内提供可靠的浪涌钳位保护。
二、主要参数
- 极性：双向
- 反向工作电压 Vrwm：24 V
- 击穿电压 VBR：约 26.7 V
- 钳位电压 Vc（峰值脉冲时）：约 38.9 V
- 峰值脉冲电流 Ipp：77.1 A
- 峰值脉冲功率 Ppp：3 kW（在厂商标准脉冲测试条件下）
- 反向漏电流 Ir：约 2 μA
- 封装：SMC (DO-214AB)
- 类型：TVS，双向
三、核心特性
SMDJ24CA/TR13 采用玻璃钝化结，提供良好的电气稳定性和长期可靠性；内置应力消除设计提高了热机械性能，适合回流焊工艺；低电感结构使其对高频瞬态同样有效，钳位能力出色，可在短时浪涌下迅速限制电压幅度，保护下游元件免受过压损坏。
四、典型应用
- 各类数据通信接口与 I/O 保护（如以太网、串口、USB 等）
- AC/DC 开关电源输入端与输出端的浪涌保护
- 工业控制、仪表以及电源适配器的过压防护
双向结构特别适合交流或需要双向浪涌防护的系统。
五、封装与装配建议
SMC 封装适合自动贴装与回流焊流程。为达到最佳保护效果，应尽可能将 TVS 器件放置在被保护端口与接地（或电源参考点）之间的最短路径处，缩小回路面积，使用足够宽的铜箔以降低寄生阻抗。对于高功耗或反复浪涌环境，建议在焊盘下方或附近设置热扩散铜箔和过孔以利于散热。
六、设计与可靠性注意事项
选型时除关注 Vrwm 与击穿电压外，应确保钳位电压在被保护电路可承受范围内；反向漏电流 Ir（约 2 μA）在高阻电路中需评估对偏置影响。长期多次浪涌会导致器件热应力积累，应根据应用环境评估能量余量与器件寿命。双向器件在直流系统中等同于两只反向并联的单向 TVS，注意额定参数差异。
七、采购与替代
型号：SMDJ24CA/TR13，品牌：Brightking（台湾君耀），封装 SMC。选购时留意电气参数与包装条码/托盘信息以便生产使用。若需替代品，可选取电压与能量等级相近且封装兼容的 TVS 器件，比较钳位电压、峰值脉冲功率及封装散热能力以保证替换后仍能满足系统要求。

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.
