LTV-814 是一款高性能的光电耦合器,广泛应用于电气绝缘、信号隔离和数据传输等需求较高的电子系统中。该器件由台湾光宝 (LITEON) 研发,利用光电隔离技术实现输入与输出之间的高效电气隔离,特别适用于交流(AC)和直流(DC)信号的传输。LTV-814 以其优越的性能和广泛的应用领域受到了工程师的青睐。
通道数与隔离电压: LTV-814 设计为单通道结构,具有高达 5000Vrms 的电气隔离电压,为敏感电路提供了良好的保护。这样的高隔离电压在医疗电子、工业自动化和消费电子等领域的应用中,能够有效降低系统故障风险。
电流传输比: 该器件的电流传输比在 1mA 的工作条件下从最小 20% 到最大 300% 范围内变化,意味着它适应了不同负载条件下的信号传输需求。在实际应用中,这使得光耦能够更灵活地根据不同的驱动电流进行设计。
响应速度: LTV-814 的上升时间和下降时间典型值分别为 4µs 和 3µs,确保其在高速数据传输过程中能够保持良好的响应性能。这一特性非常适合在数据通信、信号处理等高速应用场景中使用。
输出类型与电流能力: 该光电耦合器提供晶体管输出,能够承受最大 50mA 的输出电流,且输出电压最大可达 35V。这使得 LTV-814 可以在多种负载下安全运行,适应不同应用的电流需求。
正向电压与饱和压降: LTV-814 的正向电压(Vf)最低为 1.2V,直流正向电流(If)最大可达 50mA。其 Vce 饱和压降最大为 200mV,确保在开关状态下仍然保持较低的功耗,提升了整体效率。
工作温度范围: LTV-814 支持宽广的工作温度范围,从 -30°C 到 110°C,符合一些苛刻环境下的工作要求,使其适合在各种严苛条件下稳定工作,极大地拓展了其应用领域。
封装与安装类型: LTV-814 采用 4-DIP(0.300",7.62mm)封装,适合通孔安装。这种封装方式不仅方便焊接,也使得其在 PCB 板上布置更加灵活。
LTV-814 的广泛应用场景包括但不限于:
总之,LTV-814 光电耦合器以其高性能的电气特性、广泛的应用领域以及优秀的可靠性,成为电子工程师设计中的重要选择。其适应性强、响应速度快的特点,使其在复杂电路中得以良好运作,是现代电子系统中不可或缺的元器件之一。选择 LTV-814,意味着选择了卓越的性能与信赖的品质。

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.
