GAQY214S 产品概述

一、产品简介

GAQY214S 是 SUPSiC(国晶微半导体)推出的一款小型固态继电器级光耦/固态开关,触点形式为 SPST-NO(1 Form A)。器件以 SOP-4 封装提供,适用于对体积、隔离与控制电流有一定要求的低功率开关场合,额定负载电压可达 400V。

二、主要参数与特点

  • 触点形式:SPST-NO (1 Form A)
  • 连续负载电流:150 mA(额定)
  • 负载电压:400 V(最大)
  • 正向压降 Vf:1.2 V(典型,输入 LED)
  • 建议正向驱动 If:7 mA(触发电流参考)
  • 导通电阻:20 Ω(典型)
  • 隔离电压(Vrms):1.5 kV
  • 导通时间 Ton:230 μs;截止时间 Toff:30 μs
  • 输入类型:AC / DC 支持
  • 工作温度:-40 ℃~+85 ℃
  • 总功耗 Pd:350 mW
  • 封装:SOP-4

三、电气性能与热分析

器件导通电阻约 20 Ω,在额定连续电流 150 mA 下产生的导通压降约为 3.0 V(V = I·R),对应导通功耗 P = I²R ≈ 0.45 W,已超出器件标称 Pd = 0.35 W。因此在实际设计中应对器件进行功耗降额使用:按 Pd 与 R 计算可得到安全连续电流上限约 132 mA(√(Pd/R)≈0.132 A),建议在无额外散热措施下将连续工作电流控制在 120 mA 以下以保证长期可靠性。

导通/截止时间方面,Ton = 230 μs、Toff = 30 μs,表明开通速度相对较慢,适合直流或低频开关(如开/关控制、隔离信号驱动),不适合高频 PWM 或高速通信信号。

四、典型应用场景

  • 工业控制与传感器接口的电隔离与开关
  • 微控制器驱动的低功率负载隔离(继电器替代)
  • 测试测量、仪表中对高压侧开/关控制
  • 家用电器和消费电子中的低速开关应用

五、设计与使用建议

  • 驱动端:If 建议取 7 mA 左右,若使用 AC 输入请保证双向驱动或器件内部支持反向电流。
  • 热管理:若需接近 150 mA 工作,必须评估 PCB 散热、加装散热铜箔或使用并联器件;常规应用建议 ≤120 mA。
  • 高压侧布局:负载端为 400 V 等级,PCB 设计需保证充分的爬电与间隙距离,并在输入输出间保持良好隔离。
  • 抗干扰与浪涌保护:在感性或电容性负载上并联 RC 或 MOV 抑制突波与瞬态电压,避免器件承受过高 dv/dt 导致误触发或击穿。
  • 测试与验证:建议在目标工作温度与长时间通电条件下验证温升与漏电特性,确认开关损耗满足系统寿命要求。

六、封装与可靠性

SOP-4 紧凑封装,便于表贴组装和批量生产。器件工作温度范围宽(-40 ~ +85 ℃),隔离电压 1.5 kVrms 满足工业级常见隔离要求。选型时需综合考虑导通损耗与散热条件,若应用要求更高电流或更大隔离电压,应考虑更大功率或更高绝缘等级的器件。

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
