AT172-CuH-S(SOP-4)产品概述

AT172-CuH-S 是 AOTE(奥特)出品的一款小功率固态继电器,采用 MOS 输出结构并封装于 SOP-4。器件面向低电压、低电流的电子开关应用,具有高速响应、无机械触点磨损和长寿命等固态继电器的固有优势,适合精密控制和小型化电路设计。

一、主要性能亮点

  • 连续负载电流:500 mA,适用于小功率负载的长期导通。
  • 负载电压最大值:60 V(DC),满足常见工控和信号隔离场景。
  • 导通电阻(Rds_on):1.5 Ω,导通时功耗可按 Pd = I^2·R 估算(500 mA 时约 0.375 W)。
  • 隔离耐压(Vrms):3.75 kV,提供可靠的输入-输出电气隔离能力。
  • 输入类型:支持 AC 与 DC 驱动,前向压降 Vf = 1.4 V(If = 50 mA,指输入 LED 典型测试条件)。
  • 导通/截止响应:Ton ≈ 2 ms、Toff ≈ 1 ms,满足多数控制与信号切换需求。
  • 工作温度范围:-40 ℃ ~ +85 ℃,适应较宽的环境温度条件。
  • 绝缘电阻:1000 MΩ(典型或最小值,须参照完整数据手册)。

二、典型电气与热设计建议

  • 考虑到 Rds_on 为 1.5 Ω,长时间满载(500 mA)会产生约 0.375 W 的耗散,建议在高环境温度或封装密集布局时适当降额(例如 70%~80% 额定电流)或增加散热通道。
  • 对于感性负载(继电器线圈、电机、阀门等),应在输出端并联 RC 吸收网络或 TVS,抑制开关过冲与反向电压,保护 MOS 输出。
  • 输入端若以交流信号驱动,需注意双向驱动时的整流与限流措施,保证 If 不超过器件额定值(50 mA 为典型测试点,实际使用请参照数据手册)。

三、应用场景

  • 工业控制与自动化:用于继电器替代、信号隔离与小负载通断控制。
  • 通信与仪器:遥测、电源管理及测试设备中的隔离开关。
  • 家电与照明:小功率灯具、面板开关及智能控制模块。
  • 汽车电子(非高压动力回路):需遵循汽车级规范与额外验证。

四、封装与选型提示

  • 封装:SOP-4,四引脚小型封装,便于表面贴装与批量生产。典型引脚:两脚为输入(LED 驱动)、两脚为输出(MOS 通断),具体引脚定义、封装尺寸与焊接温度曲线请参照厂方数据手册。
  • 型号识别:AT172-CuH-S(AOTE 品牌),采购时请确认批次、认证与出货测试报告,若用于关键系统建议要求样品验证。

五、安装与可靠性注意事项

  • 焊接工艺遵循 SOP-4 的回流曲线,避免过高峰值温度对封装材料造成损伤。
  • PCB 布局时保证输入与输出地线隔离,留出足够的爬电距离和绝缘区域,以发挥 3.75 kV 的隔离能力。
  • 高湿、高污染环境下应考虑涂覆或额外绝缘保护,保持绝缘电阻指标。

总结:AT172-CuH-S 以其紧凑的 SOP-4 封装、可靠的隔离性能和适用的开关特性,适合低电压、低电流隔离开关场合。在实际设计中,应关注导通功耗、热管理及对感性负载的抑制措施,结合厂方完整数据手册完成最终电路定型与可靠性验证。

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
