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。
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。
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。
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。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
