LTV-480P-TA1-H 产品概述

一、产品简介

LTV-480P-TA1-H 是台湾光宝(LITEON)推出的一款单通道逻辑输出光耦合器,专为工业与嵌入式系统中需要电气隔离的数字信号传输设计。器件在 4.5V~30V DC 工作电压范围内可直接驱动多种逻辑电平和继电器/驱动电路,具有良好的抗干扰能力与器件可靠性,适合在严苛环境下使用。

二、主要特性

  • 工作电压(VCC):4.5V ~ 30V DC,适配多种供电方案。
  • 隔离电压(Vrms):3.75 kV,提供可靠的输入/输出电气隔离。
  • 共模瞬态抗扰度(CMTI):20 kV/μs,对快速变化的共模干扰具有良好抑制能力。
  • 通道数:1(单通道)。
  • 工作温度范围:-40 ℃ ~ +105 ℃,适合工业级温度要求。
  • 传播延迟:tpLH = 250 ns、tpHL = 250 ns,适用于中低速数字信号隔离。
  • 输出驱动能力:最大输出电流 50 mA。
  • 封装:SOP-6(体宽约 6.8 mm),便于波峰/回流焊装配。

三、电气参数要点

  • 输入正向电流 If(测试或典型值):10 mA;典型正向电压 Vf ≈ 1.33 V(在 If 条件下)。
  • 输入阈值电流 FH:5 mA,确保在此电流及以上时输出能可靠切换。
  • LED 直流反向耐压 Vr:5 V,建议在电路设计中避免对 LED 施加反向高压。
  • 器件耗散功率 Pd:145 mW,设计时需考虑封装散热与环境温度的降额处理。

四、封装与热性能

  • 封装形式为 SOP-6,脚距与外形适合自动化贴装和标准 PCB 布局。
  • 在高温或高功耗应用中应注意功耗管理与散热路径,遵循厂商给出的功耗-温度降额曲线以保证长期可靠性。

五、典型应用场景

  • 工业控制信号隔离(PLC、步进/伺服驱动信号)
  • 电源管理与电机驱动的逻辑隔离
  • 微控制器与高压/高噪声侧之间的数字接口
  • 开关电源反馈环路、继电器驱动隔离
  • 测试测量与医疗仪器中低速数字隔离

六、使用建议与注意事项

  • 为保证逻辑输出可靠切换,输入 LED 驱动电流建议不低于 FH(5 mA),典型驱动 10 mA。
  • 输出若为开漏/晶体管结构,需在应用侧配置合适的上拉电阻;上拉电压不得超过器件允许的工作电压范围(4.5V~30V)。
  • 输出最大允许电流 50 mA,长期工作接近极限会影响可靠性,应留有裕量。
  • 注意 LED 反向电压 Vr(5 V)限制,避免瞬态反向电压损伤。
  • 在高 dv/dt 环境中利用 20 kV/μs 的 CMTI 特性可以有效减少误触发;但对极端电磁干扰仍需合理的 PCB 布局和滤波措施。
  • 参照厂商数据手册进行温度降额及封装焊接工艺限制的校核。

七、订购与品牌信息

  • 品牌:LITEON(台湾光宝)
  • 封装:SOP-6-6.8mm
  • 型号:LTV-480P-TA1-H
    如需批量采购或获取完整数据手册、典型应用电路与降额曲线,建议联系授权经销商或访问 LITEON 官方技术资料以获取最新规范与可靠性测试数据。

Sourcing availability signal

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
