AZ1045-04F 产品概述
一、产品简介
AZ1045-04F 是 KUU 品牌的一款四通道瞬态电压抑制器（TVS），为低电压高速信号线与电源线提供瞬态过压、静电放电（ESD）和脉冲干扰保护。器件采用 DFN2510-10 小型封装，适合对 PCB 布局面积敏感并要求低寄生电容的应用场合。
二、主要电气参数
- 钳位电压（Vc）：15 V（典型值），在脉冲事件中限制电压幅值，保护后端电路。
- 反向工作电压 Vrwm：5 V，适合 5 V 工作系统（如 USB、I/O 口等）。
- 击穿电压（Vbr）：9 V，保证在超出 Vrwm 时可靠触发导通。
- 峰值脉冲功率 Ppp：60 W，支持单次高能量脉冲吸收。
- 峰值脉冲电流 Ipp：4 A，满足短时大电流吸收需求。
- 反向电流 Ir：1 μA（典型），在正常工作电压下漏电小，降低静态功耗。
- 结电容 Cj：0.2 pF，非常低，适合高速信号线的瞬态保护而不会显著影响信号完整性。
- 通道数：4 路，能够同时保护多条信号线或差分对。
- 工作温度：-55 ℃ ~ +125 ℃，适应工业级温度范围。
- 兼容性测试：满足 IEC 61000-4-2（ESD）与 IEC 61000-4-4（EFT）抗扰度等级。
三、封装与可靠性
器件采用 DFN2510-10 封装，尺寸紧凑、热性能和焊接可靠性良好，便于贴片自动化生产与高密度布板。工业级温度规格保证在严苛环境中稳定工作，适合工业控制、通信终端和车载电子（非安全关键）等应用。
四、典型应用场景
- USB、UART、I2C 等 5 V 或低压 I/O 接口的过压/ESD 保护；
- 高速数据链路（因低 Cj 特别适合对信号完整性要求高的差分对）；
- 消费类、工业控制模块的输入端防护；
- 较低能量的脉冲干扰环境下的系统前端保护。
五、选型与布局建议
- 放置位置：尽量靠近外部连接器或信号源一侧放置，最短路径到地，减小走线感应。
- 接地处理：提供低阻抗的接地回路，优先使用大面积接地平面并靠近器件焊盘。
- 串联元件：遇到反复高能脉冲或需要限制冲击电流，可与小阻值串联电阻配合使用以分担能量。
- 热与功率考量：Ppp 为单次峰值吸收能力，若应用中存在重复脉冲或长时间高能脉冲，应评估器件温升与散热，必要时采用并联或更高功率等级器件。
六、注意事项
- 请以厂家完整规格书为准，确认器件单向/双向配置、最大箝位电压曲线与脉冲能量曲线，以满足具体系统需求。
- 在高频/高速应用中，尽量减小管脚到 PCB 的阻抗和走线长度，以保障信号完整性与防护效果。
AZ1045-04F 以其低结电容、四通道设计和工业级温度范围，适合需要兼顾高速信号和可靠瞬态保护的电子系统。若需更详细的电气特性曲线和封装图，请参考 KUU 官方数据手册或联系供应商获取样片与评估支持。

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.
