TLP719 (TP, F) 产品概述

一、产品简介

TLP719 (TP, F) 是东芝(TOSHIBA)推出的一款单通道逻辑输出光耦,针对需要直流隔离和抗瞬态干扰的工业与电源控制场合而设计。器件采用6-SDIP(鸥翼)封装,输入为发光二极管(LED),输出为逻辑兼容的光电晶体管/输出级,整体性能在隔离强度、共模抗扰性和工作温度范围上都具备良好表现,适用于PLC、逆变器、驱动与数字隔离接口等应用。

二、主要规格亮点

  • 输入类型:DC 驱动
  • 工作电压范围:5.5 V ~ 30 V(器件在该范围内可适配多种直流供电场合,具体应用请参考数据手册)
  • 输出耐压/隔离电压(Vrms):5 kV(满足多数工业隔离需求)
  • CMTI(抗共模瞬变抑制率):10 kV/µs(在快速共模脉冲环境中仍能保持输出稳定)
  • CTR(电流传输比):20%(典型值,指在规定 If 条件下的输出响应比例)
  • 通道数:1(单通道隔离)
  • 工作温度:-55 ℃ ~ +100 ℃(宽温区,适合苛刻环境)
  • 传播延迟:tpLH ≈ 800 ns,tpHL ≈ 800 ns(开关速度为中等,适用于控制与信号隔离,但不用于高频高速通信)
  • 耗散功率(Pd):45 mW(典型,设计时需注意热管理)
  • 输出电压标称:20 V(器件在输出侧的常见参考电压指标,设计时请结合系统实际电压)
  • 正向压降(Vf):1.65 V(LED 正向压降典型值)
  • 封装:6-SDIP(鸥翼脚)

三、典型应用场景

  • 工业控制信号隔离(PLC 输入/输出隔离)
  • 电源与逆变器控制回路(光耦隔离栅极驱动、信号采样隔离)
  • 电机驱动与变频器中的数字隔离与抗干扰接口
  • 微控制器与高压侧电路之间的安全隔离
  • 仪器仪表与传感器信号隔离

四、设计与使用建议

  • 驱动LED时选定合适的限流电阻,使 LED 工作在推荐 If 区间,以兼顾 CTR 与寿命;由于 CTR 典型为 20%,输出电流需按此比例与输入电流匹配以保证负载驱动能力。
  • 输出侧若为开集电极/开漏结构,应配置合适的上拉电阻,上拉电压不应超过器件允许的最大值(结合数据手册与系统电压设计)。
  • 注意器件的耗散功率与封装热阻,长时间高温工作时进行必要的降额使用。
  • 对于需要高共模抗扰的应用,考虑合理布局和屏蔽,减少输入/输出引线长度,配合适当滤波与去耦。
  • 在高电压隔离应用中,留意爬电距离与穿透距离,满足系统安全标准要求。

五、可靠性与注意事项

  • 器件支持 -55 ℃ 至 +100 ℃ 的宽温工作范围,可在严苛环境下长期使用,但在极端高温下仍需留意性能漂移与寿命影响。
  • 传播延迟在 800 ns 级别,适合控制类与状态信号隔离,不建议用于对时延敏感的高速串行链路。
  • 为确保安全与长期稳定性,请在最终设计中参照东芝官方数据手册进行详细参数核对与测试验证。

总结:TLP719 (TP, F) 是一款面向工业级隔离与抗干扰需求的单通道逻辑输出光耦,具有 5 kVrms 隔离能力与 10 kV/µs 的 CMTI,适用于需要可靠隔离且对速度要求适中的控制和监测场景。选择与设计该器件时,应结合 CTR、LED 驱动电流、热耗散与系统电压要求做综合考量。

Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.

Buyer sourcing scenarios

Examples of how common component sourcing requests are organized.

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
