TLP188 晶体管输出光耦产品概述
一、产品简介
TLP188 是东芝（TOSHIBA）推出的一款单通道晶体管输出光耦，采用 SOP-4-2.54mm 封装。器件以发光二极管驱动光电三极管，输入为直流（DC）驱动，输出为光电三极管形式，适用于需要电气隔离与信号传输的场合。器件隔离电压达到 3.75 kV(rms)，工作温度范围宽 (-55℃～+110℃)，适应工业环境。
二、主要特点与性能
- 上升/下降时间：2 μs（上升，2 mA、100 Ω），3 μs（下降，2 mA、100 Ω），响应速度适中，适合一般控制与接口应用。
- 输入/输出电气参数：正向电压 V_F≈1.25 V（典型），反向电压 V_R≈5 V。输出允许集电极电压（负载电压）最高可达 350 V，输出电流可达 50 mA。
- 饱和性能：集射极饱和电压 V_CE(sat) 约 400 mV（典型测试条件如 Ic=2.4 mA、IF=8 mA），导通时压降小，有利于降低功耗。
- 可靠性：单通道设计，封装紧凑，适用于 PCB 布局受限的场合。
三、典型应用
适用于电源开关隔离、微控制器接口、电平转换、继电器驱动前端、工业控制信号隔离以及需要高电压耐受与安全隔离的场合。特别适合以 DC 信号驱动且对响应时间要求不是极端严格的系统。
四、封装与可靠性说明
SOP-4-2.54mm 形式便于表面贴装与插件混合装配，东芝品牌保证制造与测试规范，长寿命与温度耐受性良好。隔离电压 3.75 kV(rms) 可满足多数工业隔离要求，但在高压或安全关键场合仍需参照系统级安全标准设计。
五、使用建议
在设计时注意 LED 正向电流与外部限流电阻配合，避免超过器件 IF 极限；输出侧若驱动较大负载，应考虑散热与电流保护；在高干扰环境中建议增加滤波与缓冲，保证信号稳定与寿命。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
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.
