TLP5701 是东芝(TOSHIBA)生产的一款晶体管输出型光隔离器(光耦),封装为 SO-6L,内部由发光二极管(LED)与光敏晶体管耦合而成。器件用于在 DC 信号链路中实现电气隔离与电平移位,具有良好的隔离耐压与工作温度范围,适合工业与消费类电子中常见的接口隔离需求。
以上参数为设计时的关键依据,实际电气参数(如 CTR、输出饱和电压 VCE(sat)、集电极-发射极耐压等)请以原厂数据手册为准。
SO-6L 封装适合自动贴片与回流焊工艺。设计时应预留足够的爬电与空气间隙以配合 5 kVrms 的隔离需求;印制板布局上将高压侧与低压侧明确分区,避免污染物带来的表面泄漏。器件在 -40 ℃ 至 +110 ℃ 环境内可可靠工作,但长期高温应考虑热降额与寿命影响。
在最终选型前,确认数据手册中关键指标:CTR(光电流传输比)、输出饱和电压 VCE(sat)、集电极-发射极耐压、最大开关频率以及脉冲承受能力。根据系统要求选择合适的 If 工作点与上拉电阻,保证隔离等级、响应速度与长期可靠性之间的平衡。特殊应用(高速、精密模拟信号或高温环境)建议咨询厂方资料或选用专用高速或高隔离等级产品。

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.
