US1M 快恢复二极管产品概述

一、产品核心身份与定位

US1M是GOODWORK(固得沃克) 推出的快恢复/高效率独立式二极管,属于通用型中高压小电流整流器件,聚焦“低导通损耗+快开关速度”核心特性,适配工业控制、汽车电子、电源模块等场景的整流/续流需求,是小型化电子设备的高性价比选择。

二、关键电气参数解析

US1M的参数设计围绕“中高压、快恢复、低损耗”平衡,核心指标的实际意义如下:

  1. 正向压降(Vf):1.7V@1A
    典型工作电流下的导通电压,相比普通整流二极管(如1N4007),兼顾快恢复特性与低功耗——导通损耗(P=Vf×If)在1A时仅1.7W,可减少设备发热;
  2. 直流反向耐压(Vr):1kV
    额定反向阻断电压,覆盖220VAC整流后(峰值311V)、1000V以内直流系统的耐压需求,无需额外串联器件;
  3. 额定整流电流(If):1A
    连续正向工作电流,适配中小功率设备(如50W以内电源、LED驱动)的整流回路;
  4. 反向漏电流(Ir):5μA@1kV
    1kV反向电压下漏电流极小,说明器件反向耐压可靠性高,长期工作不易因漏电流发热失效;
  5. 反向恢复时间(Trr):75ns
    快恢复二极管的核心指标,比普通整流二极管(Trr≥1μs)快10倍以上,可有效降低开关过程中的反向恢复损耗,提升开关电源效率(适配100kHz~1MHz开关频率);
  6. 工作结温范围:-50℃~+150℃
    宽温覆盖极端环境,可适应汽车发动机舱(高温)、北方户外设备(低温),无需额外温度补偿。

三、物理封装与可靠性设计

US1M采用SMA(DO-214AC)表面贴装封装,兼具小型化与可靠性:

  • 体积紧凑:封装尺寸约2.1mm×5.0mm×1.0mm,适合便携式充电器、微型电源模块等高密度布局场景;
  • 独立式结构:无集成并联/串联,散热路径清晰,可通过PCB铜箔优化散热(1oz铜箔下,1cm²铜箔可辅助散发热量);
  • 焊接兼容性:支持回流焊、波峰焊,焊接温度≤260℃/10s,满足工业级焊接工艺要求。

四、典型应用场景

US1M的参数特性适配多类场景:

  1. 开关电源二次整流:AC-DC电源输出整流、DC-DC变换器续流回路,快恢复时间减少开关损耗,电源效率可提升至90%以上;
  2. 汽车电子:车载充电器、LED大灯驱动、小型车载逆变器,宽温范围适应汽车环境(-40℃~+125℃);
  3. 工业控制模块:PLC输入输出模块、小型变频器辅助电源,1kV耐压满足工业系统需求;
  4. LED驱动电源:中功率LED路灯、面板灯整流部分,低导通损耗减少电源发热,延长LED寿命。

五、选型与使用注意事项

  1. 降额设计:实际应用需降额(电流≤0.8A,电压≤800V),避免长期过载;
  2. 散热优化:SMA封装散热面积有限,连续1A工作时需增加PCB铜箔面积;
  3. 频率匹配:Trr=75ns适合≤1MHz开关频率,超高频需选更高速器件;
  4. 静电防护:存储/焊接需防静电(ESD等级≥2kV),避免器件失效。

US1M以“高性价比+平衡特性”成为中小功率快恢复应用的主流选型,可覆盖多数常规整流/续流场景的需求。

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
