LTV816D 为单路晶体管输出型光电耦合器,输入侧为直流 LED,输出侧为光电三极管,采用 DIP-4 封装。器件设计用于在电气隔离的两端传递数字或模拟信号,典型应用包括 MCU 隔离、开关电源反馈、工业控制信号隔离等。该型号由 UMW(友台半导体)供应,具有较高的隔离电压和宽广的电流传输比(CTR)范围,适合通用隔离场合。
总结:LTV816D(UMW / 友台)为单通道晶体管输出光耦,适合一般工业与电子隔离应用,特点是高隔离电压、宽 CTR 范围与中等开关速度。设计时请基于最差 CTR、功耗限制与环境温度进行余量设计,并参照原厂数据手册完成最终验证。

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.
