SMAJ24CAQ 产品概述
一、主要性能特点
SMAJ24CAQ 是扬杰（YANGJIE）推出的双向瞬态抑制二极管（TVS），采用DO-214AC（SMA）低外形封装，适合自动贴装。该器件对瞬态电压具有极快响应能力和优异的钳位特性，能在10/1000 μs脉冲（雷击/浪涌仿真）下承受高达400 W的峰值脉冲功率，峰值脉冲电流为10.3 A。器件工作温度范围宽（-55 ℃ 至 +175 ℃），适合严苛环境应用。
二、关键电气参数
- 极性：双向（Bi-directional）
- 反向截止电压 Vrwm：24 V（最大连续工作电压）
- 击穿电压 VBR：29.5 V（在规定电流下）
- 钳位电压 Vc：38.9 V（10/1000 μs 波形条件下）
- 峰值脉冲电流 Ipp：10.3 A（10/1000 μs）
- 峰值脉冲功率 Ppp：400 W（10/1000 μs）
- 反向电流 Ir：1 μA（在 Vrwm 条件下）
这些参数表明该器件在保护24 V 级信号和电源总线上，提供对瞬态过电压的可靠钳位与能量吸收能力。
三、封装与机械特性
SMA（DO-214AC）封装，体积小、散热路径短，利于表面贴装和波峰/回流焊加工。低外形设计便于在有限空间内布局。典型引脚与封装尺寸符合行业贴装设备和PCB布局需求。
四、典型应用场景
SMAJ24CAQ 适用于各种需要瞬态抑制的场合，包括但不限于：
- 汽车电子：车载传感器、点火线圈开关、电源总线（满足-55~+175 ℃工作）
- 工业与消费类电子：MOSFET 驱动、控制信号线、继电器/接触器开关保护
- 通信设备与传感器节点：防止由雷电或感性负载开关导致的电压瞬变
其双向特性使其特别适合交流或双向信号线保护。
五、选型与使用建议
- 连续工作电压应低于 Vrwm（24 V），留有裕度以避免长期加速老化。
- 对于直流供电线路，若仅单向冲击，亦可考虑单向型号以获得更低的钳位电压；双向器件适用于交流或正负反向浪涌。
- 在高能量冲击应用中，应评估 PCB 铜箔面积和散热设计，以便及时散热并避免封装过热失效。
- 验证钳位电压（38.9 V）是否对下游器件安全可接受，必要时配合串联阻抗或熔断器以分担能量。
六、可靠性与焊接注意事项
器件耐温宽，适合汽车级标准。建议遵循制造商焊接曲线进行回流焊，避免长时间高温停留。存储与回流处理应防潮防静电，贴片后尽量减少机械应力。实际应用时应结合系统级浪涌试验验证保护效果与可靠性。
总结：SMAJ24CAQ 提供了针对24 V 级系统的高能量、快速响应的双向浪涌保护方案，封装适合自动贴装，适用于汽车、工业及通信等多种场景。

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.
