ATV252-CuH-S(SOP-6)固态继电器(MOS 输出)产品概述

一、产品简介

ATV252-CuH-S 是 AOTE(奥特)推出的一款基于 MOSFET 输出的固态继电器,封装为 SOP-6,面向低电压大电流的 DC/AC 负载控制场合。器件集成了输入驱动与双向 MOS 输出(支持 AC/ DC 控制输入),具有高绝缘强度与低导通电阻的特点,适用于工业控制、通信设备、电源开关与一般负载切换等场景。

二、主要规格参数

  • 连续负载电流:3.5 A(连续)
  • 负载电压(最大):60 V
  • 输出导通电阻(典型):40 mΩ
  • 输入 LED 正向压降(Vf):1.3 V(If = 50 mA)
  • 输入正向电流(If):50 mA
  • 导通时间(Ton):约 2.5 ms;截止时间(Toff):约 150 μs
  • 隔离电压(Vrms):5 kV(输入/输出隔离)
  • 绝缘电阻:1000 MΩ
  • 总功耗 Pd:650 mW
  • 输入类型:支持 AC、DC(内置整流/驱动结构)
  • 工作温度范围:-40 ℃ ~ +85 ℃
  • 封装:SOP-6

三、性能与热设计要点

  • 低导通电阻带来的电压降 Vdrop = I × R ≈ 3.5 A × 0.04 Ω ≈ 0.14 V,输出端功耗约 0.49 W(I^2R),低于器件 Pd(650 mW),但接近边界,建议在实际应用中进行适度降额或强化 PCB 散热(加大铜箔面积、使用散热地/电源层、采用通孔导热)。
  • 输入侧 Vf×If ≈ 1.3 V × 50 mA = 65 mW,驱动功耗较小。
  • Ton ≈ 2.5 ms 表明器件开通较慢,不适合要求高频 PWM 的场合;Toff 较短(150 μs),关断响应较快。适合用于开/关频率较低的控制场景。

四、应用建议与限制造成

  • 典型应用:PLC 输出模块、小型电机与风扇的低压直流控制、加热器/灯负载开关、通信与仪器设备中的开关隔离。
  • 不建议用于:直接在高压市电(>60 V)或需要高频开关(数 kHz 以上)和高浪涌电流的负载(如大功率感性负载无抑制)。对感性负载建议并联 RC 吸收或 TVS,避免 MOSFET 承受反向尖峰。
  • 输入驱动:支持 AC 与 DC 控制信号(器件内置整流/驱动),但应按规格限制 If(50 mA)设计驱动电流,并保证驱动线路可靠绝缘与限流保护。

五、PCB 及安装注意事项

  • SOP-6 封装,焊盘设计应确保良好散热,建议在输出引脚下方或附近布置大片铺铜并连通过孔到背面散热层。
  • 保持输入侧与输出侧的爬电、间隙距离以满足 5 kV 隔离要求,遵循相应的安全规范与国标绝缘距离。
  • 对于高电流路径,增大走线宽度并使用多层过孔以降低导通电阻和局部升温。

六、选型与使用提示

  • 型号:ATV252-CuH-S;品牌:AOTE(奥特);封装:SOP-6。
  • 在实际系统中留出足够的热裕量(推荐在最大环境温度下工作电流低于标称 3.5 A,或采用外部散热处理),并在感性负载场合采取抑制措施。
  • 对于需要更高开关频率或更大电流/电压能力的应用,可在选型时考虑更高规格的 MOS 输出 SSR 或功率 MOSFET 方案。

本产品以低导通损耗、良好隔离与紧凑封装见长,适合在受限空间内实现可靠的低压负载开关控制。若需资料(如封装图、引脚定义、典型应用电路或热阻数据),可进一步索取数据手册以完成最终电路设计与布局验证。

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
