DFLZ5V6-TP 产品概述
一、产品简介
DFLZ5V6-TP 是美微科（MCC）推出的一款表面贴装齐纳二极管，标称齐纳电压 Vz = 5.6V，额定功率 1W，容差 ±5%。封装为 SOD-123FL，适配现代 SMT 生产线，适用于需要稳定参考电压或低功耗过压保护的电子系统。
二、主要特点
- 齐纳电压（标称）：5.6V，容差 ±5%
- 最大耗散功率：1W（铜箔和散热条件决定实际允许功率）
- 工作结温范围：-55°C ~ 150°C（TJ）
- 反向漏电流：10µA @ 2V（典型）
- 正向压降：Vf = 1.2V @ If = 200mA
- 动态阻抗（Zzt）：≤5 Ω（最大值）
- 封装：SOD-123FL，表面贴装，利于自动贴装与回流焊接
三、典型应用
- 电源基准与基准源电路（小功率电压参考）
- 信号线和电路板局部过压保护与钳位
- 电源去耦与稳压补偿（低电流场合）
- 工业控制、消费电子、通信模块的本地稳压与保护电路
四、设计与使用注意
- 功率限制：长期工作时不得超过 1W，实际允许耗散受 PCB 散热能力影响；建议查阅完整器件热阻与 PCB 布局指导。
- 工作电流选择：选择合适的偏流以保证 Vz 稳定，过低电流会使齐纳电压漂移，过大电流会导致过热。
- 正向电流：若存在较大正向电流（如短路时），需评估 Vf 在 200mA 时约 1.2V 的压降与能量承受能力。
- 温度影响：工作温度范围广，但在高温下漏电流与功率耗散能力会变化，应按实际环境留余量。
五、典型电路与示例
常见恒压电路为串联限流电阻 Rs 与齐纳并联负载。设计 Rs 可依据公式：Rs = (Vin - Vz) / Iz，其中 Iz 为预计通过齐纳的偏流（示例计算请以数据表中推荐条件为准）。在含有瞬态或大电流脉冲场合，应配合限流与热保护措施。
六、封装与装配
SOD-123FL 小型低高度封装，适合贴片机自动装配和标准回流焊工艺。推荐按厂家提供的 PCB 焊盘尺寸与回流曲线进行设计和焊接，以保证良好焊点与热散能力。适用于批量生产的卷盘式包装（Tape & Reel）。
七、可靠性与品质保障
器件按工业级温度规格测试，符合一般静态和热循环可靠性要求。为获得长期可靠性，应注意 PCB 散热设计与避免长期接近额定极限工作点。有关详细电气特性曲线、热阻和机械尺寸，请参考 MCC 官方规格书和器件数据手册。
如需样品、详细规格书或推荐 PCB 焊盘尺寸与回流曲线，可联系供应商或查询 MCC 官方文档获取完整技术资料。

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.
