G3VM-61VY2-TR是欧姆龙(OMRON)推出的小型化MOS输出固态继电器,采用1 Form A(SPST-NO,单刀单掷常开)触点形式,针对低功率直流负载的精准控制场景开发。作为无机械触点的继电器产品,它摆脱了传统机械继电器的磨损、电弧、噪声等痛点,同时兼顾小型化、快速响应与高隔离特性,是高密度电路设计中的理想控制元件。
该产品的电气参数直接决定适用场景,核心参数可分为五大维度:
连续负载电流额定值为500mA,负载电压上限60V(直流),完美匹配绝大多数低功率直流负载——如小型LED阵列、微型直流电机、传感器信号切换、小型继电器线圈驱动等,避免了大功率负载带来的散热压力,契合小型封装的热设计要求。
输入输出端隔离电压达3.75kV(RMS交流有效值),绝缘电阻≥1000MΩ,满足工业级电气隔离标准:
导通时间(Ton)600μs,截止时间(Toff)100μs——该速度远快于传统机械继电器(毫秒级响应),可满足高频切换场景(如脉冲信号控制、快速负载循环),且无触点切换无机械疲劳,理论寿命可达百万次以上。
导通状态下正向压降(Vf)1.27V,导通电阻1Ω,额定负载(500mA)下总损耗约0.635W(I×Vf),在SOP-4封装的热容量范围内,无需额外散热设计即可稳定工作。
工作温度区间为-40℃+110℃,覆盖工业级(-4085℃)与部分汽车级(-40~125℃)温区,可适应户外设备、低温车间、高温控制柜等极端环境,无需降额使用。
G3VM-61VY2-TR采用SOP-4(小外形封装),引脚间距2.54mm,符合表面贴装工艺(SMT)要求,可通过自动化贴片机生产,大幅提升组装效率。其典型尺寸约3.9mm×2.5mm,可节省PCB空间30%以上,适合智能家居控制器、小型仪器仪表、汽车辅助电子模块等对体积敏感的产品。
基于参数特性,该产品典型应用场景包括:
作为全球继电器领域领先品牌,欧姆龙为该产品提供严格质量管控:需通过高低温循环、振动冲击、盐雾测试等工业级可靠性试验,符合RoHS、REACH环保标准,可确保长期复杂环境下的稳定工作,降低系统维护成本。
综上,G3VM-61VY2-TR以“小型化、低损耗、高隔离、宽温适应”为核心优势,是低功率直流负载控制场景的高性价比选择。

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.
