LTV-207 是 LITEON(台湾光宝)推出的双通道晶体管输出光隔离器,采用 8-SOP 表面贴装封装,适用于数字信号隔离与低速开关接口。器件以发光二极管驱动光电晶体管,提供高达 3750Vrms 的隔离耐压,适合工业与消费电子场合的信号隔离需求。
LTV-207 提供较高的 CTR(100% ~ 200% @10mA),在中低偏置电流下即可获得较好的输出电流增益,利于低功耗驱动设计。最大输出耐压 80V 和低 VCE(sat)(≤400mV)使其在常见逻辑侧和控制侧电平中能稳定工作。典型开关时间为几微秒级,适合脉冲、开关和一般数字通信隔离,但不适合高速总线或精密模拟信号的实时隔离。
LTV-207 采用 8-SOP 封装,双通道并排布局,适合常见 PCB 表面贴装工艺。器件额定工作温度为 -55°C 至 110°C,满足多数工业级温度要求。隔离等级满足 3750Vrms 的安全隔离需要,可用于需要一定电气安全隔离的系统设计。
总结:LTV-207 是一款性能均衡、适用于一般数字隔离与工业控制场景的双通道晶体管输出光隔离器,具有高隔离电压与良好的 CTR 表现,适合在可靠性和成本之间寻求平衡的设计方案。

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.
