UFM14PL-TP 产品概述
一、产品简介
UFM14PL-TP 是美微科（MCC）推出的一款快恢复、高效率整流二极管，采用 SOD-123FL 封装，面向开关电源、适配器、充电器及各种功率转换与保护电路。该器件在 1A 工作电流下具有较低正向压降，并在高达 400V 的反向电压条件下保持极低漏电流，兼顾能效与可靠性。
二、主要性能参数
- 正向压降 (Vf)：1.4V @ IF = 1A
- 直流反向耐压 (Vr)：400V
- 整流电流：1A（连续）
- 反向电流 (Ir)：10 μA @ VR = 400V
- 反向恢复时间 (Trr)：50 ns（典型）
- 非重复峰值浪涌电流 (Ifsm)：30A（单次浪涌）
- 工作结温范围：-65℃ ~ +150℃
- 封装：SOD-123FL
- 品牌：MCC（美微科）
三、产品特点与优势
- 快恢复特性（Trr≈50ns），在开关转换过程中降低开关损耗和电磁干扰（EMI），适合高频开关应用。
- 低正向压降（1.4V@1A），降低导通功耗，提高系统整体效率。
- 高耐压等级（400V）与低漏电流（10μA@400V），适用于高压总线及待机低功耗场景。
- SOD-123FL 小型封装，有利于高密度 PCB 布局和热量扩散，适合空间受限的消费电子产品。
四、典型应用
- 开关电源（SMPS）整流输出或钳位二极管
- 适配器、电源模块、LED驱动电源
- 电池充电与电源管理系统
- 反向保护、续流/自由放电二极管
五、热与可靠性注意事项
- 在设计中应考虑封装的热阻及PCB散热铜箔面积，连续 1A 工作时需保证良好散热路径以维持长期可靠性。
- 非重复峰值浪涌电流为 30A，应避免重复大电流冲击或在浪涌条件下超出器件额定值。
- 推荐按照制造商提供的回流焊曲线进行焊接（参考 JEDEC/IPC 标准），避免超过峰值温度并控制加热/冷却速率以减少热应力。
六、封装与焊接建议
SOD-123FL 的小型化设计利于自动化贴片生产。建议在 PCB 布局时为器件留出适当热沉铜箔，并优先采用双面过孔或散热槽增强热流路径。焊接时遵循常规无铅回流规范，焊后建议进行目视及 X 射线检查以确保焊点完整。
七、选型与系统集成提示
- 若应用为高频开关或要求更低恢复损耗，可优先考虑 Trr 较短的器件；UFM14PL-TP 的 50ns 属于快恢复类别，适中频率场合表现良好。
- 对于极低待机功耗场景，如漏电流极为敏感，应验证实际温度下的 Ir 表现并评估系统整体能耗。
- 在需要更大持续电流或更低 Vf 的场合，可考虑并联或选择更大封装的器件，但需注意均流与热管理。
如需器件封装图、典型电路图或更详细的回流曲线与可靠性数据，可联系供应商获取完整数据手册以完成最终设计验证。

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.
