LTV-816S-TA1 产品概述

一、规格概述

LTV-816S-TA1 是 LITEON 出品的一款单通道晶体管输出光耦(SMD-4P 封装),用于 DC 信号隔离与电平移位。主要参数如下:正向压降 Vf ≈ 1.2V,正向电流 If 最大 50mA,输出电流(集电极电流)最大 50mA,隔离电压 Vrms 5kV,直流反向耐压 Vr 6V,输出耐压(负载电压)可达 80V。典型集-射饱和电压 VCE(sat) 100mV(@ IC/IF 条件见数据表),上升/下降时间分别为 tr=4µs、tf=3µs,工作温度范围 -50℃~+110℃。电流传输比(CTR)范围宽,最小 50%,最大(饱和值)可达 600%,器件总功耗 Pd = 200mW。

二、主要特性

  • 单通道光电三极管输出,SMD-4P 表面贴装,适合自动化生产。
  • 高隔离电压 5kVrms,适合工业与通信等需隔离的场合。
  • 宽 CTR 范围(50% ~ 600%),在不同工作点可获得较大输出电流放大。
  • 低 VCE(sat)(约 100mV),开关时导通损耗小;响应速度 tr≈4µs / tf≈3µs,适合中低速数字隔离。
  • 输出耐压高(80V),适合驱动较高电压侧负载。

三、典型应用

  • MCU/逻辑与高压电路之间的信号隔离与保护。
  • 电源管理与电流检测回路的隔离输出。
  • 工业控制设备、继电器驱动前端隔离、PLC 接口。
  • 模拟/数字信号隔离、噪声敏感环境中的接口防护。

四、使用建议与设计要点

  • CTR 与 If、温度有关,设计时应以最小 CTR(50%)计算最坏情况输出电流:ICmin ≈ 0.5·IF。注意 IC 不可超过 50mA 的器件极限。
  • 若以 5V 驱动 LED 并希望 IF = 10mA,则限流电阻 R ≈ (VCC - Vf) / IF = (5V - 1.2V) / 10mA ≈ 380Ω。
  • 开关速度受负载电阻、集电极容量与光耦本身特性影响,若需更快响应请在电路中采取减小负载电阻或并联加速网络等方法。
  • 热设计:器件总功耗 Pd 最大 200mW,贴片布局应提供适当散热路径与铜箔面积。
  • PCB 布局:输入输出应保持足够爬电距离与贯穿隔离槽(如需要)以确保 5kVrms 隔离能力。

五、可靠性与安全

  • 工作温度宽(-50℃~+110℃),适合严苛环境。
  • 5kVrms 隔离电压提供良好的工频耐压能力,但在高压或安全规范场合请参考完整安全认证与爬电/气隙要求。
  • 推荐在长期高湿、高温工况下进行加速寿命验证以确认 CTR 漂移与封装可靠性。

六、封装与订购信息

  • 品牌:LITEON(台湾光宝)。
  • 封装:SMD-4P(表面贴装,四引脚)。
  • 型号示例:LTV-816S-TA1。
    在选型与采购时,请参照 LITEON 官方数据手册确认各测试条件(如 VCE(sat) 测试条件、CTR 定义范围)以及使用限制,以保证设计的一致性与可靠性。

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
