ACPL-P480-560E 产品概述
一、产品简介
ACPL-P480-560E（Broadcom 博通）是一款单通道、推挽输出的光耦隔离器，典型用于数字信号隔离与逻辑驱动场合。器件提供3.75 kVrms的隔离电压与20 kV/µs的共模瞬态抗扰度（CMTI），在工业电源、电机驱动、逆变器及隔离采样等高共模变化环境中具有良好可靠性。
二、主要规格要点
- 隔离电压（Vrms）：3.75 kV
- CMTI：20 kV/µs
- 通道数：1，推挽输出（Push-Pull）
- 工作电压范围（VCC）：4.5 V ～ 20 V
- 输入参数：正向压降 Vf ≈ 1.5 V；最大正向电流 If = 10 mA；直流反向耐压 Vr = 5 V；输入阈值电流（FH）≈ 5.5 mA
- 输出参数：输出电流可达 25 mA（源/吸）
- 传播延迟：tpLH ≈ 350 ns，tpHL ≈ 350 ns（对称）
- 功耗：耗散功率 Pd ≈ 210 mW
- 工作温度：-40 ℃ ～ +100 ℃
- 封装：SO-6（6.8 mm），适合 PCB 上保持必要的爬电/空气间隙
三、性能与应用建议
- 输入侧驱动：为确保稳定开关，建议以接近 If = 10 mA 驱动 LED；若驱动电压为 5 V，则串联电阻 R ≈ (5 V − 1.5 V) / 10 mA ≈ 350 Ω（取标准阻值）。因器件 Vr = 5 V，应避免反向应力，必要时并联反向保护二极管。
- 输出侧设计：推挽输出可源/吸 25 mA，适合直接驱动逻辑负载或小型继电器驱动级。工作电源需在 4.5–20 V 范围内，建议在 VCC 旁并联 0.1 µF 去耦电容以抑制瞬态。
- 时序与带宽：传播延迟约 350 ns，适合数百 kHz 到 MHz 级别的数字隔离。若用于高速采样或反馈环路，请考虑延迟对相位裕度的影响。
- 热与功耗：单通道耗散功率约 210 mW，设计时须考虑功耗与环境温度的热降额，保证器件结温与封装散热在安全范围内。
四、布局与可靠性建议
- 保持高压侧与低压侧的爬电距离和空气间隙，利用器件 6.8 mm 封装特性布局走线，必要时增加隔离槽或障蔽。
- 在具有高 dv/dt 的应用中，利用良好的接地和旁路电容降低共模耦合噪声，发挥 20 kV/µs 的 CMTI 优势。
- 在输入端加入限流与反向保护，在输出端避免超出 25 mA 电流与 210 mW 功耗极限，延长使用寿命。
五、典型应用场景
- 电源与逆变器控制信号隔离
- MCU 与高压侧驱动隔离（栅驱前端信号）
- 工业通信接口、开关电源反馈、数据采集隔离等
总结：ACPL-P480-560E 提供高隔离电压与优秀的共模瞬态抗扰度，推挽输出与较低延迟适合工业级数字隔离需求。合理的输入驱动、电源去耦与 PCB 布局可以发挥其稳定与可靠的隔离性能。

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.
