EL3H7(D)(TA)-VG 是由台湾亿光(EVERLIGHT)制造的一款高性能光耦合器(光隔离器),采用表面贴装型封装(4-SOIC)。该光耦具备优异的电气特性,主要用于在高压和低压电路之间提供电气隔离,同时实现信号的有效传输,广泛应用于工业控制、通讯设备和消费电子等领域。
电气隔离能力: EL3H7(D)(TA)-VG 的绝缘电压高达 3750Vrms,使其能够有效地隔离高压电路,保护低压控制电路,这对于确保设备安全运行至关重要。这种高隔离电压的设计,使其适合在要求严格的应用环境中使用,如电源管理和工业自动化。
电流传输比: 此产品在 5mA 的输入电流下,具备最小值为 300% 和最大值为 600% 的电流传输比。这意味着在输入端输入一定的电流后,输出端将能够输出高达输入电流 3 到 6 倍的电流,确保了良好的信号传递能力。这一特性使得光耦能够在功率较低的输入条件下实现较强的输出。
响应时间: EL3H7(D)(TA)-VG 拥有快速的上升和下降时间,分别为 5µs 和 3µs,这使其在快速开关信号的应用中表现出色,能够适应高频率的工作环境。例如,在数据通信或脉冲信号处理等场合,快速的响应时间确保了高效的数据传输和信号完整性。
输出特性: 产品的最大输出电压为 80V,而最大输出电流则为 50mA。此外,典型的正向电压(Vf)为 1.2V,DC 正向电流最高可达 50mA,Vce 饱和压降不超过 200mV,提供了稳定的输出性能与低功耗的优势。
广泛的工作温度范围: EL3H7(D)(TA)-VG 的工作温度范围宽广,从 -55°C 到 110°C,这使得其能够在极端环境条件下稳定工作,适合于各种工业应用和恶劣工作条件下的使用。
封装与安装: 此器件采用 4-SSOP 封装(4-SOIC,0.173",4.40mm 宽),表面贴装设计使得 PCB(印刷电路板)设计更为精简,有助于提高装配效率并降低生产成本。
EL3H7(D)(TA)-VG 的设计特点使其广泛适用于多种应用场景,尤其是在以下几个领域表现突出:
EL3H7(D)(TA)-VG 凭借其卓越的技术参数和优异的性能,成为光隔离器市场上的重要选择,能够满足不同行业对于电气隔离和信号传递的需求。其强大的电流传输能力、宽广的工作温度范围以及高隔离电压,使其在现代电子设备中得以广泛应用,为用户和系统提供了安全可靠的解决方案。
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.
