AZ1345-04F 产品概述
一. 概述
AZ1345-04F 是 KUU 推出的一款四路超低电容瞬态电压抑制器（TVS），专为高速数据接口保护设计。器件在保持高耐受性的同时，将 I/O 到 I/O 的结电容限制在典型 0.2pF，极大减小对高速信号完整性的影响，适合 HDMI、DVI 及其他高速差分/单端数据线的防护需求。
二. 主要特性
- 超低结电容：I/O–I/O 典型 0.2pF，最低寄生，兼容高频信号。
- 四路保护：一次器件即可保护四条高速通道，节省 PCB 空间与成本。
- 高耐冲击能力：符合 IEC 61000-4-2（ESD，±15kV 空气、±8kV 接触）与 IEC 61000-4-4（EFT，40A，5/50ns）规范；同时支持 CDM 与 CDE 类放电事件。
- 低钳位：典型钳位电压 15V，减小被保护芯片上的应力。
- 优异静态特性：反向截止电压 Vrwm = 5V，击穿电压 VBR = 9V，反向漏电流 Ir = 1μA（典型）。
- 峰值脉冲功率：Ppp = 60W，满足短时大能量瞬态抑制。
三. 关键参数一览
- 类型：TVS（双向/单向请按电路需求确认）
- 通道数：4 路
- 结电容（I/O–I/O）：0.2pF（典型）
- Vrwm：5V；VBR：9V；钳位电压：15V
- 反向电流 Ir：1μA
- 峰值脉冲功率 Ppp：60W
- 工作温度：-55℃ ~ +125℃
- 封装：DFN2510-10
四. 应用场景与建议
适用于对信号完整性要求高且需可靠防护的高速接口，如 HDMI、DVI、USB3.x 上行/差分对、摄像头接口与高速串行链路。推荐靠近接口或连接器放置，走线短且对称，使用地平面与多个过孔引下地线以提高吸收与散热能力。
五. 布局与使用注意
- 放置位置：尽量靠近受保护端口的连接器或插座。
- 地线处理：短路径回流，增加地过孔，避免长环路。
- 信号影响：尽管结电容极低，差分线匹配仍需控制阻抗与长度。
- 热与可靠性：在高能量环境下注意器件功耗与散热，保证工作温度范围内可靠运行。
AZ1345-04F 结合超低电容、高耐受性与小封装，能够在不牺牲信号质量的前提下，为高速数据线提供有效的瞬态过压与静电放电保护。

Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
