SMAJ24CA/TR13 产品概述
一、产品简介
SMAJ24CA/TR13 是台湾 Brightking（君耀）出品的一款双向瞬态抑制二极管（TVS），封装为 SMA（DO-214AC），专为 24V 等级电源与信号线的浪涌保护设计。该器件在 10/1000µs 波形下可承受 400W 峰值脉冲功率（Ppp），对浪涌和瞬态过压具有快速响应和可靠钳位能力。
二、主要参数
- 类型：双向 TVS（双极性）
- 反向截止电压 (Vrwm)：24V
- 击穿电压 (Vbr)：29.5V（典型）
- 钳位电压 (Vc)：38.9V（在 Ipp 条件下）
- 峰值脉冲功率 (Ppp)：400W @ 10/1000µs
- 峰值脉冲电流 (Ipp)：10.3A @ 10/1000µs
- 反向漏电流 (Ir)：1µA（在 Vrwm 条件下）
- 封装：SMA (DO-214AC)
以上参数为典型/额定值，具体使用时请参照厂方完整规格书和测试条件。
三、产品特性与优势
- 快速响应：对电源线与信号线上出现的瞬态电压瞬间钳位，保护下游器件免受击穿损伤。
- 高能量吸收：400W@10/1000µs 的脉冲能力，适合应对雷击感应和开关操作产生的高能脉冲。
- 低漏电流：Vrwm 条件下仅 1µA，适合对静态功耗敏感的系统。
- 双向设计：可在正、负方向对称钳位，适合交流或双向浪涌场景。
四、典型应用场景
- 24V 工业控制与自动化设备的电源保护；
- 通信设备与接口（如 PoE 及中继线缆）的防雷与浪涌保护；
- 电源线、继电器驱动回路、传感器和现场总线（如 RS-485）端口保护；
- 其他需要双向瞬态抑制的电子系统。
五、封装与 PCB 布局建议
- SMA（DO-214AC）封装适合波峰/回流焊组装，推荐在焊盘间保持适当热沉和散热铜箔以改善能量吸收能力。
- 靠近被保护端口布局，尽可能缩短引线与走线长度以降低寄生感抗，提升保护响应速度。
- 若用于高能量场合，可并联相同规格或更大功率的 TVS，但需注意热平衡与稳态电流分配，推荐遵循厂方并联指南。
六、可靠性与注意事项
- 遵守厂方的最大额定值和热阻条件，避免长期在高脉冲或过温环境下连续工作；
- 在高能冲击后建议测试器件是否仍能满足原有钳位性能，必要时更换；
- 储存与焊接时注意静电防护与推荐的回流焊曲线，避免超温损伤封装或芯片。
七、替代与选型提示
- 在需要更高钳位或更低钳位时，可参考同系列不同 Vrwm/Vc 等级型号；
- 如需更大脉冲能量，考虑更大封装（如 SMB/SMC）或并联设计；
- 选型时综合考虑系统工作电压、容许漏电流、响应速度和环境温度等因素。
SMAJ24CA/TR13 以其 24V 反向截止、电力级脉冲承受能力与双向保护特性，是工业与通讯领域常见的稳健选择。欲获取完整电气特性曲线与工程应用资料，请参考 Brightking 官方规格书或联系供应商获取技术支持。

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.
