GAQY210EH 产品概述

一、产品简介

GAQY210EH 是 SUPSiC(国晶微半导体)推出的一款小封装固态继电器/光耦式隔离开关器件,采用 SMD-4 封装,提供 5kVrms 的输入—输出隔离能力。器件为单刀单掷常开(1A)触点形式,输入可接受 AC 或 DC 驱动,适合对小功率直流或交流信号进行电隔离和开关控制的场合。

二、主要特点

  • 隔离电压:5kVrms,满足高压隔离需求;
  • 触点形式:1A(单刀单掷 - 常开);
  • 输入特性:正向压降 Vf ≈ 1.2V,典型驱动电流 If = 7mA,支持 AC / DC 驱动方式(驱动 AC 时需注意整流和限流处理);
  • 输出特性:允许最大负载电压 350V,连续负载电流 130mA,导通电阻约 17Ω;
  • 功耗与开关速度:总功耗 Pd = 350mW,导通时间 Ton ≈ 230μs,截止时间 Toff ≈ 50μs;
  • 工作温度范围:-40℃ ~ +85℃;
  • 封装:SMD-4,适合表面贴装自动化生产。

三、电气性能要点

GAQY210EH 的输入端为 LED 驱动,典型正向压降 1.2V、建议驱动电流 7mA,可直接由 MCU 输出或通过限流电阻/驱动级控制。输出采用固态开关结构,导通电阻约 17Ω,在连续负载 130mA 下可可靠工作,但需注意总功耗 350mW 的热限。开关速度属于中等:开通约 230μs,关断约 50μs,适合一般控制、测量和通信隔离场景,但不适合高速开关应用。

四、封装与热管理

SMD-4 小型封装利于密集布板和自动贴装,但热量主要通过焊盘向 PCB 散热,建议在 PCB 下方或附近增加散热铜箔与过孔,保证在持续 130mA 负载下器件温升受控,并遵循厂商的焊盘和走线建议以防焊接应力影响可靠性。

五、典型应用场景

  • 工业控制信号隔离与小电流驱动;
  • 智能表计与传感器接口的电气隔离;
  • 家电与白色家电的微功率开关控制;
  • 通信与测试设备中需要高隔离的控制通道;
    (不建议用于高瞬态冲击或大电流电源开关场合,具体请参照完整数据手册)

六、选型与使用建议

  • 驱动侧:若为直流驱动,按 Vf 与 If 计算限流电阻;若为交流驱动,需考虑半波或全波整流以及反向耐受能力;
  • 热限与寿命:在高温环境下应做功率降额(derating),避免长期在额定功耗附近工作;
  • PCB 布局:保证输入与输出之间的爬电、空气间隙符合系统安全要求;输出侧走线应考虑电压幅值与散热;
  • 测试:上板前进行静电防护(ESD)和焊接温度验证,完成后做功能与隔离耐压测试。

七、可靠性与验证

器件额定工作温度 -40℃ ~ +85℃,隔离等级 5kVrms 提供良好抗干扰能力。实际应用时应做整机级的温度循环、湿热和耐压测试以验证系统可靠性。

总体而言,GAQY210EH 在小体积、高隔离和中等切换速度的应用中具有良好性价比,适合需要可靠隔离且负载电流较小的场合。欲获得更详细的电气参数、引脚定义及推荐 PCB 布局,请参考厂商完整数据手册或联系 SUPSiC 技术支持。

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
