LTV-214 是 LITEON(台湾光宝)出品的一款单通道晶体管输出光电耦合器(phototransistor optocoupler),用于实现直流信号的电气隔离与传输。器件以低输入正向压降、较高隔离电压和较宽的工作温度范围为特点,适合在需要信号隔离、噪声抑制以及逻辑电平匹配的场合使用。封装为 SOP-4(175 mil),便于 PCB 布局与批量贴装。
总结:LTV-214 是一款适合工业控制与通用信号隔离的晶体管输出光耦,凭借 3.75 kV 的高隔离电压、最高 50 mA 的输入/输出能力和宽温度范围,能在多种需要电气隔离的低中速场合中稳定工作。设计时请结合 CTR、VCE(sat) 与实际电流需求进行裕量计算,并参照原厂 datasheet 获取完整的测试条件与限制。

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.
