EVERLIGHT ITR2006ST30A/TR(晶体管输出光耦)产品概述

一、产品简介

ITR2006ST30A/TR 是台湾亿光(EVERLIGHT)推出的一款表面贴装(SMD)光电隔离器,输入端为发光二极管(LED),输出端为光电三极管(Phototransistor)。器件用于实现低功耗、高可靠性的电气隔离,适合数字信号传输、开关检测及一般隔离整合电路。器件体积小、响应速度适中,适用于需要光电隔离且对封装尺寸有要求的应用场合。

二、主要参数(基准值)

  • 输入类型:DC(发光二极管)
  • 输出类型:光电三极管
  • LED 正向压降(Vf):1.23 V(典型)
  • 最大正向电流(If):50 mA(脉冲/峰值限制,具体注意额定曲线)
  • LED 反向耐压(Vr):5 V
  • 输出最大集电极-发射极耐压(负载电压):30 V
  • 输出电流(Ic,典型/最大工作):20 mA(应用时按数据手册限制)
  • 集射极饱和电压 VCE(sat):约 400 mV(在 Ic≈10 mA 或 0.1 mA 条件下给出)
  • 上升/下降时间(tr / tf):约 15 μs(典型)
  • 工作温度范围:-25 ℃ ~ +80 ℃
  • 封装:SMD(卷带供料,适合自动贴装)

三、关键特性与优势

  • 小尺寸 SMD 封装,适合自动化贴片生产与高密度 PCB 布局;
  • 光电三极管输出,支持开集电极结构,便于与上拉电阻形成数字接口;
  • 低 VCE(sat)(约 0.4 V),在导通时具有较小的压降,有利于降低功耗;
  • 中等响应速度(上/下降时间均约 15 μs),适合开关信号和一般数据速率应用;
  • LED 正向压降较低(≈1.23 V),在低电压驱动时更为友好。

四、典型应用场景

  • 微控制器间电气隔离与逻辑信号隔离;
  • 开关/按键状态检测、光耦输入端防抖与隔离;
  • 工业控制、家用电器的低速数据/状态传输;
  • 电源管理与系统监测中的隔离检测电路。

五、设计与使用建议

  • LED 驱动限流:根据供电电压与期望 If 计算串联电阻。例:在 5 V 驱动、目标 If=10 mA 情况下,R = (5 - 1.23) / 0.01 ≈ 377 Ω(可选 380 Ω);在 3.3 V 驱动、If=10 mA 时,R ≈ 207 Ω(可选 200 Ω)。
  • 输出侧上拉:光电三极管通常作为开集电极输出,需外接上拉电阻至所需逻辑电平。上拉电阻大小视所需导通电流与速度权衡,常见范围为 4.7 kΩ ~ 100 kΩ。若要求较快响应和较大输出电流,可采用较小阻值。
  • 电压与功耗:输出端最大允许负载电压 30 V,应避免超过该值。同时注意器件在高 If 条件下的热耗散与可靠性。
  • 反向保护:LED 反向耐压仅 5 V,电路设计中避免反向电压冲击或在必要时并联反向保护二极管。
  • 焊接与可靠性:采用标准无铅回流工艺进行贴装,遵循供应商的回流曲线建议,避免超出温度限制。

六、包装与选型提示

  • 型号后缀/TR 表示卷带(Tape & Reel)包装,适合 SMT 自动贴片生产线;
  • 在选型时留意 If 的持续与脉冲额定、工作环境温度与响应速度要求,必要时参考原厂完整数据手册以获取时序、CTR(若需)、最大额定值和安全规范等详细信息。

七、可靠性与环境适应

  • 工作温度覆盖 -25 ℃ 到 +80 ℃,适合一般室温及工业环境;
  • 在潮湿、振动或强电磁干扰的环境中,应采取板级防护与滤波、去耦设计,以保证长期稳定性。

总结:ITR2006ST30A/TR 为一款适合常规数字隔离和状态检测的 SMD 光耦器件,特点是体积小、驱动电压低、响应速度适中。采用时请关注 LED 驱动限流、输出上拉设计及器件最大电压/温度限制,并以原厂数据手册为准进行最终电路与可靠性验证。

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
