GAQW210S 产品概述

一、产品简介

GAQW210S 是 SUPSiC(国晶微半导体)推出的一款双刀单掷(2A,常开)固态开关器件,采用 SOP-8 封装,集成光电隔离与输出开关元件,输入可直接驱动 AC 或 DC。器件面向信号与小功率电源隔离开关场景,具有高耐压、小尺寸、快速响应和高绝缘强度等特点,适合工业控制、通信模块、电源管理与家电等应用。

二、主要电气参数

  • 触点形式:2A(双刀单掷,常开)
  • 连续负载电流:120 mA(最大长期通过能力)
  • 负载电压:350 V(最大可阻断电压)
  • 正向压降(输入 LED,Vf):1.2 V(典型)
  • 正向电流(输入驱动 If):7 mA(典型触发电流)
  • 导通电阻(R_on):17 Ω(典型) → 在 120 mA 时导通压降约 2.04 V,导通功耗约 0.245 W(I^2·R)
  • 隔离电压(Vrms):1.5 kV(最大绝缘等级)
  • 导通时间(Ton):280 μs,截止时间(Toff):100 μs(适合低频与脉冲控制)
  • 输入类型:AC / DC(内置整流或双向驱动兼容)
  • 工作温度:-40℃ ~ +85℃
  • 总功耗(Pd):350 mW(器件整体热耗限制)
  • 封装:SOP-8

三、器件特性与优势

  • 高压阻断能力(350 V)配合 1.5 kVrms 隔离,适合隔离要求高的系统设计。
  • 低输入驱动(典型 7 mA),可直接由 MCU 或工业控制器驱动;支持 AC 输入,简化外部整流电路。
  • 小封装(SOP-8)便于密集 PCB 布局与批量生产。
  • 典型导通电阻 17 Ω,在额定电流下器件功耗可控(需注意 Pd 与散热)。
  • 开关速度适中(数百微秒量级),适用于多种控制信号切换但不用于高频 PWM 驱动。

四、设计与热管理建议

  • 在 120 mA 连续工作情况下器件自身导通损耗约 245 mW,接近器件 Pd(350 mW)的 70% 水平,建议在高环境温度或密封空间内做适当热设计(扩大铜箔散热、增设通孔、降低环境温度或降低负载电流)。
  • 输入端建议串联限流电阻或按 MCU 输出能力设计驱动电路,确保 If 达到典型触发值且不超过输入最大额定值。
  • 输出回路应避免过冲与高 dv/dt 应力,必要时加入负载侧抑制元件(RC 抑制或 TVS)以保护器件。
  • 对于长导线或高 EMI 环境,注意布线和接地,保证隔离性能与信号完整性。

五、封装、可靠性与应用场景

  • 封装:SOP-8,便于贴片装配与自动化生产;建议参考厂方封装图纸设计 PCB。
  • 可靠性:工作温度范围宽、隔离强度高,适合工业级产品。建议在设计阶段参考器件的温度系数与老化特性,进行必要的温升与寿命测试。
  • 典型应用:信号隔离与切换、通信设备继电器替代、测控系统小功率负载控制、家电控制板、工业传感器供断控制等。

六、选型提示与常见电路

  • 若系统需更大负载电流或更低导通压降,应选用 R_on 更低或更高功耗等级的器件。
  • 常见接法:MCU -> 限流电阻 -> 输入引脚(可接 AC/双向),输出端串入负载与电源端,低电平常开时无导通,输入驱动使两组触点导通。
  • 选择 GAQW210S 时,请结合最大导通功耗 Pd、工作环境温度、持续电流与开关频率做全面评估,必要时与供应商确认器件在目标工况下的热阻与寿命数据。

Sourcing availability signal

Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.

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
