GAQW211G2EH 产品概述

GAQW211G2EH 是 SUPSiC(国晶微半导体)推出的一款光电隔离固态继电器(或光耦式固态开关)级产品,采用 SMD-8 表面贴装封装,面向需要高隔离、低导通损耗和较快关断响应的直流/交流控制场景。器件在输入端支持 AC/DC 驱动,输出端采用低导通电阻的半导体开关结构,适合对小功率电源和负载进行可靠、无触点控制。

一、主要特性概述

  • 隔离电压(Vrms):5 kV(工频绝缘强度高,满足严苛隔离要求)
  • 触点形式:2A(双刀单掷 - 常开)
  • 输入类型:支持 AC、DC 驱动,LED 正向压降 Vf ≈ 1.2 V(在 If = 50 mA 时)
  • 输出电气:连续负载电流 2.5 A,导通电阻 RON ≈ 60 mΩ,最大负载电压 40 V
  • 开关性能:导通时间 Ton ≈ 800 μs,截止时间 Toff ≈ 20 μs(关断较快,导通上升相对缓慢)
  • 功耗与温度:总功耗 Pd = 2 W,工作温度范围 -40 ℃ ~ +85 ℃
  • 封装:SMD-8 贴片封装,便于自动化装配和高密度 PCB 布局
  • 品牌:SUPSiC(国晶微半导体)

二、产品优势(应用角度)

  • 高隔离安全:5 kVrms 隔离能力适合用于控制侧与电力侧严密隔离的系统,提升系统安全与抗干扰能力。
  • 低导通损耗:60 mΩ 的低导通电阻在 2.5 A 工作电流下可显著降低功耗与发热,有利于减小散热设计复杂度。
  • 双刀单掷常开:双刀输出可实现两路负载同时隔离控制,适用于需要对两路电源或双通道开关控制的场合。
  • 输入兼容性:支持 AC 与 DC 驱动,LED 驱动电压低(Vf 约 1.2 V),便于与多种控制器、PLC 或继电器驱动电路直接接口。
  • 快速关断:20 μs 的较快关断时间有利于在需迅速断开负载的保护/故障清除场景中应用。

三、典型应用场景

  • 工业自动化控制:输出隔离、驱动电源或低压继电器替代,用于 PLC、控制模块与执行器之间的隔离开关。
  • 通信与仪表:需要高隔离与低漏电的小功率开关场合,如基站供电管理、测试测量设备等。
  • 便携/电池供电系统:低导通损耗有助于延长电池续航,适合便携仪器或便携充电设备。
  • 家电与消费类电子:用于风扇、电磁阀、小型泵等负载的无触点控制(在额定电压/电流范围内)。
  • 过载/保护电路:作为短路保护或回路断开器件,与检测电路配合使用。

四、关键电气建议与使用注意

  • 驱动电流:典型输入 If 50 mA 时 Vf ≈ 1.2 V,设计驱动电阻和驱动器时应留有裕量,避免超温或 LED 过驱。
  • 散热处理:Pd = 2 W 为器件最大总耗散,长时间在接近额定电流下工作时需在 PCB 布局上采取散热措施(铺铜、散热垫、热沉或过孔热通)。
  • 开关频率与 PWM:Ton ≈ 800 μs,Toff ≈ 20 μs,器件适合低频或间断控制,不适合高频 PWM 精细调制或音频带宽切换。
  • 感性负载保护:对感性负载(电机、继电器线圈等)使用时,建议并联 RC 或 TVS 器件以抑制反向冲击和浪涌电压,保护器件寿命。
  • 最大负载电压与浪涌:器件标称最大负载电压 40 V,设计时应避免超过此电压,并尽量限制浪涌电流和反向电压尖峰。
  • 焊接与可靠性:SMD-8 封装适合回流焊工艺,推荐按照供应商回流温度曲线和焊盘布局指南进行 PCB 设计与焊接以保证可靠性。

五、封装与系统集成提示

  • 封装:SMD-8,便于 SMT 自动化贴装,适合紧凑 PCB 布局。
  • PCB 布局建议:输出端采用宽铜带、局部加厚铜层和多层散热通孔;输入端信号线与高电压输出端保持合理间距,满足爬电/杂散耐压要求。
  • 可靠性设计:在高湿、高温或高 EMI 场景下,应结合实际环境加大隔离间距、采用涂覆或屏蔽等保护措施,保证长期稳定工作。

总结:GAQW211G2EH 以高隔离电压、低导通电阻与用心的封装形式,适合在工业控制、仪表、家电及便携电源等多领域替代传统机械继电器与常规模块,尤其在需要安全隔离与低功耗散热的场合具有明显优势。设计时应关注散热、感性负载抑制与驱动电流匹配,以发挥器件最佳性能。

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.
