GAQW214S 产品概述

一、产品简介

GAQW214S(品牌:SUPSiC,国晶微半导体)是一款双刀单掷(2A,双通道常开)固态继电器 / 光耦式开关器件,采用 SOP-8 封装。器件支持 AC 与 DC 输入驱动,具有高隔离电压与较低导通电阻,适合对小电流、高电压信号进行安全隔离与开关控制的场合。

二、主要参数

  • 触点形式:2A(双刀单掷 - 常开)
  • 连续负载电流:100 mA
  • 最大负载电压(阻断):400 V
  • 正向压降(Vf):1.2 V(典型)
  • 正向电流(If):7 mA(驱动典型值)
  • 导通电阻(Ron):20 Ω(典型)
  • 隔离电压(Vrms):2.5 kV
  • 导通时间(Ton):230 μs
  • 截止时间(Toff):30 μs
  • 输入类型:AC / DC(可双向驱动输入端)
  • 工作温度范围:-40 ℃ ~ +85 ℃
  • 总功耗(Pd):350 mW
  • 封装:SOP-8

三、功能与优势

  • 高电压阻断能力:最大 400 V 的负载电压允许在较高电位差场合实现安全断开。
  • 良好隔离性能:2.5 kVrms 的隔离电压可用于模拟/数字回路与高压侧之间的安全隔离。
  • 低功耗与稳健导通:典型导通电阻 20 Ω,在 100 mA 下的导通功耗约为 0.2 W(I^2·R),低于器件 Pd,便于在小信号场合长期运行。
  • 宽温度范围与双向输入:支持 -40~85 ℃ 工作温度,输入支持 AC/DC,便于直接与交流或直流控制信号兼容。
  • 小体积封装:SOP-8 适合集成到密集 PCB 布局中,便于替代机械继电器实现无触点开关。

四、典型应用场景

  • 仪表与测试设备:用于信号路由、隔离与开断小电流高压信号。
  • 通信与基站设备:对射频、控制逻辑的小电流开关与隔离。
  • 智能电表与传感器接口:替代机械继电器进行长寿命开关控制。
  • 工业控制与 PLC I/O:用于低功率隔离型开关回路。
  • 医疗电子(非直接接触病人回路):需要查看相关医规认证后使用。

五、设计与使用注意事项

  • 驱动要求:典型 If 为 7 mA,建议按照实际环境(温度、老化)适度放大驱动电流裕量,并在输入侧配置限流电阻。若长期使用 AC 输入,确认器件内部整流/双向结构以合理选择限流/滤波元件。
  • 功耗与散热:在满载 100 mA 时,器件导通端功耗约 0.2 W/通道,总功耗应控制在 Pd = 350 mW 内,必要时采用 PCB 散热铜箔或降低工作电流。
  • 开关速度:Ton ≈ 230 μs、Toff ≈ 30 μs,适合低频率控制与开关应用,但不适合高频 PWM 或快速脉冲切换。
  • 绝缘与爬电距离:设计 PCB 时保证与高压侧的爬电距离与穿越距离满足 2.5 kVrms 的隔离要求,并遵循对应安规标准。
  • 并联与冗余:若需超过单通道电流能力,应采用并联或并配置多通道,同时注意电流共享问题与保护电路设计。

六、封装与安装建议

  • SOP-8 小封装便于自动化贴装。焊接时遵循标准回流曲线,避免过高温度和过长热敷时间。
  • 布局建议将高压侧和低压侧走线分区布置,输入端与控制器尽量靠近、输出端走高压隔离区,保持良好接地与 EMI 控制。
  • 对于长期稳定性,建议在设计时留有测试点以便现场检修与老化评估。

七、选型建议

选择 GAQW214S 时,请确认应用的最大连续电流不超过 100 mA、待切换的频率低于器件响应能力、并确保系统隔离与散热设计满足器件 Pd 与工作温度要求。具体引脚定义、绝对最大额定值与典型特性曲线,请参照 SUPSiC 官方数据手册以完成电路设计与可靠性验证。

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
