TPAZ1143-04F 产品概述
一、产品简介
TPAZ1143-04F 为 TECH PUBLIC（台舟电子）推出的四路单向 TVS/ESD 静电与浪涌保护二极管，采用 SOD-323 小体积封装。器件针对 3.3V 工作系统设计，兼容 IEC 61000-4-2（ESD）、IEC 61000-4-4（EFT）与 IEC 61000-4-5（浪涌）等级的抗扰度要求，适用于高速信号和电源线路的瞬态过压保护。
二、主要电气参数
- 反向工作电压 Vrwm：3.3 V（适用于 3.3V 总线）
- 击穿电压（Vbr）：约 4 V（启动雪崩钳位）
- 钳位电压（Vclamp）：15 V（Ipp 条件下）
- 峰值脉冲电流 Ipp：4 A @ 8/20 µs（单次脉冲能力）
- 反向漏电流 Ir：60 nA（在 Vrwm 下的典型泄漏）
- 结电容 Cj：0.3 pF ~ 0.8 pF（低电容设计，适合高速信号）
- 通道数：4 路，极性：单向
- 封装：SOD-323，表贴小封装，节省 PCB 面积
三、功能与优势
- 针对 3.3V 逻辑与接口提供可靠的单向瞬态抑制；在正常工作电压下保持高阻态，避免信号畸变。
- 低结电容（0.3–0.8 pF）对高速数据线（如 USB、I2C、UART、串行接口等）的影响小，保持信号完整性。
- 小型 SOD-323 封装便于在空间受限的移动设备、工业模块和消费类电子中使用。
- 满足 IEC 静电与浪涌测试，提升产品在实际环境中的抗扰度与可靠性。
四、典型应用场景
- 手机与便携式设备的数据与控制线保护（3.3V 总线）
- 工业控制模块、传感器接口（防止工厂环境静电与瞬态浪涌）
- 消费类电子、导航与车载轻量电子（非高能量车规环境）
- 通信设备、高速接口的端口防护
五、使用与布局建议
- 单向器件：阴极接信号线，阳极接地（在 PCB 上靠近受保护的连接器或芯片放置）。
- 为获得最佳防护效果，尽量把 TVS 放置在被保护器件与外部连接器之间的最靠近外部端口的位置，焊盘到地的路径短、阻抗低。
- 注意地平面完整性与回流路径，必要时增加接地焊盘或多孔接地以降低寄生电感。
- 在高速差分对或敏感模拟线路中，评估结电容对带宽的影响，选择合适的布局以最小化串扰与带宽损失。
六、封装与订购信息
- 型号：TPAZ1143-04F
- 品牌：TECH PUBLIC（台舟电子）
- 封装：SOD-323，四路单向 TVS，适合表面贴装生产与自动化装配。
上述参数为典型值，实际选型时请参考厂商完整数据手册以获取曲线、热特性和最大额定值等详细信息，以确保在目标应用中的可靠性与合规性。

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.
