SMAJ24CA 产品概述
一、产品简介
SMAJ24CA 是扬杰（YANGJIE）推出的一款双向瞬态电压抑制器（TVS），采用 DO-214AC（SMAJ）封装，专为 24V 级电源和信号线的浪涌、雷击及电压瞬变保护设计。器件具有较低的钳位电压和高峰值脉冲吸收能力，适用于工业控制、电源模块、通讯设备和分布式供电系统的过电压保护。
二、主要电气参数
- 极性：双向（对称钳位正负方向）
- 反向截止电压 Vrwm：24V（推荐持续工作电压）
- 击穿电压 Vbr：29.5V（典型）
- 钳位电压 Vc：38.9V（在 Ipp 条件下测得）
- 峰值脉冲电流 Ipp：10.28A（10/1000 μs 波形）
- 峰值脉冲功率 Ppp：400W（10/1000 μs 波形）
- 反向电流 Ir：≤5 μA（在 Vrwm 下）
- 类型：TVS，封装：DO-214AC（SMAJ）
三、关键特性
- 双向保护：能同时钳制正向与负向瞬态，适合交流或可反向的电源/信号线路。
- 低漏电流：Vrwm 下 Ir ≤5 μA，有利于不影响系统待机功耗和精密电路工作。
- 高能量吸收：在 10/1000 μs 标准冲击波形下可吸收 400W 功率、10.28A 峰值电流，适合工业级浪涌。
- 小型封装：DO-214AC 提供良好热容量与易于自动化贴装的优势。
四、典型应用场景
- 24V 工业控制总线、PLC 接口和执行器保护。
- 通信基站、路由器等供电接口的浪涌抑制。
- 电源模块输入端、逆变器及太阳能储能系统局部保护。
- 电池管理和车辆 24V 系统（需确认车型级认证要求）。
五、选型与使用建议
- 把 Vrwm 选为略高于正常工作电压，SMAJ24CA 适用于标称 24V 系统。
- 将 TVS 尽量靠近受保护端口（连接器或输入端）布置，缩短导线回路以降低感抗。
- 若系统可能承受更大能量冲击，考虑并联或选用更高功率等级器件，并配合熔断/限流保护。
- 焊接与回流：遵循封装制造商的回流焊温度曲线（参考 JEDEC/IPC 标准，严禁超出最大峰值温度和保温时间）。
六、封装与可靠性
DO-214AC（SMAJ）封装便于自动贴装与波峰/回流焊，具有良好散热路径。器件在合适的 PCB 散热设计下可保证在多次中小能量冲击下稳定工作。设计时建议在热热点处设置散热铜箔和通孔以提升热扩散。
七、注意事项
- 请选择符合所需冲击波形（常用 10/1000 μs）的测试数据来评估系统保护能力。
- 在高温或长时间脉冲条件下注意器件的热极限与周边元件耐受性。
- 对关键应用（如汽车关键安全回路）应确认产品是否满足相关行业资格认证。
SMAJ24CA 以其双向保护、低漏电、高能量吸收等特性，是 24V 级系统实现可靠瞬态浪涌防护的常用选择。若需完整的电气特性曲线、封装尺寸及回流焊规范，建议参考扬杰官方数据手册。

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.
