GAQY214DEH 产品概述

一、产品简介

GAQY214DEH(品牌:SUPSiC / 国晶微半导体)是一款SMD-4P 封装的固态光耦/光电继电器类器件,采用单刀单掷常开(1A,Form A)触点形式,适用于对高压但低电流回路进行隔离开关控制。器件输入支持交流与直流驱动,输出端可承受高达400V的负载电压,设计上兼顾体积小、无机械触点、寿命长与电气隔离性能。

二、主要参数与含义

  • 触点形式:1A(单刀单掷-常开),表示输出为一组常开触点的固态开关结构。
  • 连续负载电流:130mA(连续工作时最大通过电流),超过该值时需考虑热设计或使用并联/更大器件。
  • 负载电压:400V(最大可阻断/承受的开路电压),适合高电压小电流开关场合。
  • 正向压降 (Vf):1.16V(LED 在推荐 If 条件下的典型/标称电压降,用于计算输入限流电阻)。
  • 正向电流 (If):50mA(LED 驱动电流规格,建议参考规格书确定持续与脉冲允许值)。
  • 导通时间 (Ton):500µs,说明器件为中等速度开关,适合频繁但非高速PWM 切换场合。
  • 输入类型:AC、DC,输入端可接受交流或直流信号驱动,增加了应用灵活性。
  • 封装:SMD-4P,适合表面贴装工艺与自动化装配。

说明:上述参数为典型/标称值,实际设计应以完整规格书中的极限值与热性能为准并留有裕量。

三、典型应用场景

  • 仪器仪表中高压小电流回路的隔离开关(测量通道、信号路由)。
  • 电源监测、保护电路与继电器替代(消除触点抖动、延长寿命)。
  • 家电控制、安防设备中对高电压线路做低频开断或逻辑隔离。
  • 通信设备与测试平台中需要光电隔离的控制接口。

四、设计与使用建议

  • 输入端驱动:按公式 R = (V驱动 - Vf) / If 计算限流电阻,确保If不超过器件额定值,并在可能的温升下留有余量。
  • 输出端热管理:连续负载130mA 已是器件的长期极限,布线和铜箔散热区域应充分考虑功耗与结温。长时间或高频切换时需评估温升。
  • 安全与PCB布局:输出端涉及高压(最高400V),PCB 设计需遵守相关爬电/气隙规范,留足间距并采取隔离槽/加厚介质等措施。
  • 开关速度:Ton≈500µs,非高速器件,若用于脉冲或PWM,请确认整体系统响应满足要求。
  • 焊接与可靠性:SMD-4P 封装支持回流焊,具体温度曲线应参照厂商回流规范;装配与维修时注意静电防护与湿敏处理。

五、封装与可靠性要点

SMD-4P 小型表贴封装便于自动化生产、节省PCB 空间。器件无机械触点、无接触磨损,理论寿命远长于机械继电器,但需注意输出侧的浪涌电流、过压以及长期热应力对失效机理的影响。建议在产品设计阶段进行热仿真与湿热/循环测试验证。

六、选型对比与优势总结

相较于机械继电器或传统光耦加外部开关方案,GAQY214DEH 的优势在于体积小、耐高压(高达400V)、对交流/直流输入兼容、无触点寿命长、开关无机械抖动。适合高压低电流、要求隔离且对机械寿命或噪声敏感的应用场合。选型时应综合考量连续电流(130mA)、开关速度(500µs)与散热约束,确保满足目标系统的功率与安全规范。若需更详细的极限参数、漏电流、隔离耐压与时序特性,请查阅供应商完整规格书或联系SUPSiC技术支持获取样片与应用建议。

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
