GAQV1122S 产品概述

GAQV1122S 为 SUPSiC(国晶微半导体)推出的一款单通道光耦合器,输入端为直流驱动的发光二极管,输出端为光电二极管。器件在保持高隔离性的同时,提供适用于微弱电流传输和电气隔离的解决方案,适合对体积、成本和隔离等级有一定要求的工业与消费电子应用。

一、主要特点

  • 单通道光电二极管输出,适合电平/脉冲信号隔离与检测。
  • 输入:正向压降 Vf ≈ 1.4V,允许正向电流 If ≤ 20mA(典型设计值)。
  • 输出:典型光电输出电流约 8 μA(在规定 If 与负载条件下)。
  • 隔离耐压:外壳间隔离实验值 Vrms = 2500V,满足多数中低压隔离需求。
  • 输出端直流反向耐压 Vr = 5V;允许负载电压(外部施加)最高至 8V(使用时需注意偏置极限)。
  • 工作温度范围:-40°C ~ +85°C。
  • 封装:SOP-4,175 mil,2.54 mm 引脚间距,单通道简洁布局,便于 PCB 布局与波峰/回流焊接工艺。

二、主要电气参数(概览)

  • 输入类型:DC 驱动 LED。
  • 正向压降:1.4V(If=20mA 时典型值)。
  • 正向电流:最大 20mA(建议根据散热与寿命适当降额)。
  • 输出电流(光电二极管):约 8 μA(典型响应电流,随光强和偏置变化)。
  • 隔离电压:2500Vrms。
  • 输出直流反向耐压:5V。
  • 负载电压:8V(器件在特定应用下允许的最高外加电压)。

三、典型应用场景

  • MCU 与高压电路之间的信号隔离(低电平脉冲、状态信号检测)。
  • 开关电源的初次/次级隔离和反馈检测(非高精度参考)。
  • 工业控制系统中低电流脉冲隔离与检测。
  • 电源管理与电路防护中的脉冲耦合与检测用途。

四、使用建议与设计要点

  • 输入侧限流:以 5V 为例,若要求 If=20mA,则限流电阻 R = (5V − 1.4V)/20mA ≈ 180Ω;实际应根据所需 CTR/输出电流与寿命考虑降额。
  • 输出偏置:若采用反向偏置以提高响应速度与线性度,注意光电二极管的最大反向耐压 Vr = 5V,不可超限。若系统要求外加负载电压接近 8V,应在电路中采取限压或保护措施,避免在反向状态下超过 Vr。
  • 隔离布局:保持输入与输出地线在 PCB 上的良好间距,避免爬电路径与杂散耦合。焊接时遵守最大回流温度与坡度,以免影响长期可靠性。
  • 使用寿命:长期以最大 If 工作会加速 LED 衰减,推荐在保证足够信号裕度的前提下采用降额驱动。

五、可靠性与注意事项

  • 在高湿或有腐蚀性气氛环境中,应加大爬电距离或采用涂覆防护层以保证长期隔离可靠性。
  • 器件在极端温度下性能(响应、光电流)会有所变化,设计时应考虑温度漂移。
  • 出厂前请参考 SUPSiC 的详细数据手册获取完整电气特性曲线、引脚排列与封装尺寸,以保证正确选型与布局。

六、总结

GAQV1122S 提供了经济、可靠的单通道光隔离方案,适用于需要中等隔离等级且输出为光电二极管形式的信号隔离场景。合理的限流设计与输出偏置控制是确保器件性能与寿命的关键。欲获取详细参数、典型特性曲线与引脚信息,请参阅 SUPSiC(国晶微半导体)官方数据手册或联系供应商技术支持。

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
