UF4007 产品概述

一、概述

UF4007(YANGJIE 扬杰,DO-41 封装)是一款面向通用整流与开关电源保护的高耐压硅二极管。该器件在直流耐压、峰值冲击能力和工作温度范围上具有良好平衡,适用于要求耐压高、占板面积小且可靠性高的电源与整流应用场景。

二、主要技术参数

  • 二极管配置:独立式(单只二极管)
  • 正向压降(Vf):1.7V @ 1A
  • 直流反向耐压(Vr):1000V(1kV)
  • 连续整流电流:1A
  • 反向泄漏电流(Ir):2.5µA @ 1kV
  • 非重复峰值浪涌电流(Ifsm):30A
  • 工作结温:-55 ℃ ~ +150 ℃
  • 封装:DO-41
  • 品牌:YANGJIE(扬杰)

三、产品特性

  • 高耐压:1000V 的反向耐压使其适合中高压整流与保护电路。
  • 低正向压降:1A 条件下约 1.7V 的 Vf,有利于降低整流损耗和发热。
  • 低反向漏电:在满压条件下漏电仅为 µA 级,适用于需低漏电的电源与保护场合。
  • 抗冲击能力:30A 的非重复峰值浪涌电流满足瞬态冲击需求(如整流器开机浪涌)。
  • 宽温度范围:-55 ℃ 至 +150 ℃ 的结温范围保证在恶劣环境下稳定工作。

四、典型应用

  • 开关电源(SMPS)二次整流与续流保护
  • 工业电源整流桥与高压整流场合
  • 逆变器与电机驱动的保护回路
  • 电压钳位、吸收电路(与 R/C 配合)
  • 测试设备与仪器中需要高耐压、低漏电的整流场景

五、封装与安装注意

  • DO-41 为常见的直插封装(Axial lead),便于手工焊接与波峰焊,但焊接时应控制焊接温度与时间以保护结温。
  • 为保证长期可靠性,应在设计中考虑适当的散热与热降额:连续 1A 工作时需注意环境温度及 PCB 散热路径,避免长期靠近最大结温工作。
  • 反向漏电随温度上升明显增加,若工作环境高温需评估额外的余量。
  • 注意极性标识(环线为负极),安装时勿反向接入以免损坏器件或造成系统故障。

六、选型与替代建议

  • 若工作在更高开关频率且对恢复时间有严格要求,可考虑真空快恢复或肖特基二极管替代(需兼顾正向压降与耐压)。
  • 对于更高的连续电流需求,应选择更高额定电流或更低 Vf 的器件并改善散热设计。
  • 在选择替代型号时,优先匹配 Vr、If(平均/持续)、Ifsm 与工作温度范围,必要时验证漏电和正向压降在目标工作点的实际表现。

简而言之,YANGJIE(扬杰)UF4007(DO-41)以其 1kV 耐压、1A 整流能力和良好的冲击特性,成为中高压整流与保护电路中的稳健选择。在电路设计时应结合热管理与反向漏电特性做合理的余量与保护措施。

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
