产品概述:EL3H4(A)(TA)-VG 光耦
在现代电子设计中,光耦合器件被广泛应用于信号隔离、数据传输及驱动控制等领域。台湾亿光(EVERLIGHT)生产的EL3H4(A)(TA)-VG系列光耦,凭借其优秀的电气性能和可靠的工作特性,成为了众多高性能应用中的首选器件。
产品特性
EL3H4(A)(TA)-VG光耦具有优秀的电压隔离能力,能承受高达3750Vrms的隔离电压,大大提升了设备间的电气安全性。这种隔离特性使其在高电压环境下能够有效防止信号互干扰,保护微控制器和其他敏感器件免受电气干扰,广泛应用于工业控制、家用电器和汽车电子等领域。
在性能方面,EL3H4(A)(TA)-VG具备较宽的输入类型支持,既可以处理交流(AC)信号,也可以处理直流(DC)信号,提供了灵活的适用性。这一特点使得其适合于各种应用场合,从基本的开关信号传输到更复杂的电流检测和隔离功能。
该光耦的输出类型为晶体管,其集电极饱和压降(Vce 饱和压降)最大值仅为200mV,确保了其在开关状态下的低功耗特性。这一特性使得EL3H4(A)(TA)-VG能在高效率的条件下稳定工作,同时减少了系统的热量散发,提升了整体的系统效率。
电气参数
EL3H4(A)(TA)-VG光耦的电流传输比(CTR)具有良好的容忍度,最小值为50% @ 1mA,最大值可达到150% @ 1mA,这为设计师提供了极大的灵活性,便于在不同工作条件下进行优化设计。典型的上升时间和下降时间为6µs和8µs,这一迅速的响应速度保证了信号的及时传输,适用于高带宽需求的应用场景。
在输出性能方面,该光耦的输出电压最大可达80V,正向电压(Vf)典型值为1.2V,且其直流正向电流(If)的最大值为50mA,这些参数均为实现高效和可靠性的信号隔离和传输提供了保障。
工作环境与封装
EL3H4(A)(TA)-VG的工作温度范围广泛,从-55°C到100°C,确保其在不同环境条件下均能稳定工作。这种高温适应性使得该器件乃至整个系统在严苛的环境中都能保持长久的可靠性。
在结构设计上,该产品采用表面贴装型(SMD),封装为4-SSOP,具有紧凑的物理尺寸(0.173",4.40mm 宽),适合于空间有限的应用场合。此外,表面贴装的设计简化了装配过程,提高了生产效率。
应用场合
EL3H4(A)(TA)-VG的多种特性使其适合于各种应用场合,包括但不限于:
综上所述,EL3H4(A)(TA)-VG光耦以其卓越的电气特性和灵活的应用范围,成为现代电子设备设计中不可或缺的重要元件。无论是在工业、消费电子还是汽车领域,其出色的性能均为工程师们提供了有力的设计支持,助力他们实现更高效、更稳定的电子系统。
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.
