GAQV212G1EH是国晶微半导体(SUPSiC)推出的贴片式固态继电器,核心参数覆盖控制端与负载端的关键性能:
高隔离安全可靠
3.75kV有效值隔离电压远超常规低压继电器,可避免控制电路与负载电路的电气干扰,尤其适合医疗、通信等对隔离安全要求严格的领域(如防止高压端故障击穿控制端),提升系统抗干扰性与安全性。
快速开关响应
导通1ms、截止50us的速度比机械继电器快10倍以上,适配脉冲信号切换、高频负载循环(如智能家电变频控制、工业传感器快速通断),满足现代设备的动态控制需求。
低损耗高效能
100mΩ导通电阻在1A负载下,导通功耗仅0.1W(I²R计算);正向驱动电流仅7mA,无需大电流驱动电路,简化控制端设计,降低系统整体功耗。
宽温与长寿命
-40℃~+85℃工作温度覆盖工业现场极端环境(如户外控制柜、低温车间);无机械触点设计避免磨损、电弧烧蚀,理论寿命达百万次以上,远高于机械继电器的机械寿命,减少维护成本。
输入兼容性强
支持AC/DC输入信号,无需区分控制端交直流类型,可直接适配PLC输出、单片机IO、交流控制信号等多种控制源,提升应用灵活性。
GAQV212G1EH的参数特性使其适用于多领域中小功率负载控制:
采用SMD-6P贴片封装,尺寸紧凑,适配自动化表面贴装工艺,可集成到高密度PCB板中,节省设备空间;封装材料为耐高温、抗老化工程塑料,配合合理散热设计,确保450mW功耗下长期稳定;产品通过高低温循环、振动测试,符合工业级可靠性要求,应对复杂环境冲击与老化。
总结:GAQV212G1EH凭借高隔离、快响应、低损耗、宽温适应等优势,成为中小功率负载控制的理想选择,适用于工业、家电、医疗、通信等多领域,其贴片封装与高可靠性设计,满足现代电子设备小型化、智能化需求。
Request for quote
Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
