HS3MB快恢复/高效率二极管产品概述

一、核心参数总览

HS3MB是扬杰科技推出的SMB封装快恢复二极管,核心电气参数匹配中功率高频应用需求,具体如下:

参数名称 规格值 测试条件 正向压降(Vf) 1.7V 正向电流If=3A 直流反向耐压(Vr) 1000V 反向漏电流Ir≤5μA 平均整流电流(Io) 3A 壳温Tc=25℃ 反向恢复时间(Trr) 75ns(典型值) 开关频率适配场景 反向漏电流(Ir) 5μA Vr=1000V、Ta=25℃ 非重复峰值浪涌电流(Ifsm) 100A 8.3ms正弦波半周期 工作结温范围(Tj) -55℃~+150℃ 长期可靠工作温度

二、封装与品牌背景

1. 封装特性

HS3MB采用SMB(DO-214AA)表面贴装封装,尺寸紧凑(约4.1mm×2.6mm×1.7mm),适配自动化贴装产线,可显著节省PCB空间,满足小型化电子设备的设计需求;封装采用环氧树脂灌封,具备良好的防潮、抗振动性能,适合工业级场景。

2. 品牌支撑

由国内功率器件龙头企业扬杰科技(YANGJIE) 生产,扬杰科技专注半导体器件研发20余年,产品覆盖二极管、MOSFET、IGBT等领域,HS3MB继承了其高一致性与可靠性优势,部分批次通过AEC-Q101汽车级认证,可满足严苛的工业/车载应用要求。

三、关键性能优势

1. 快恢复特性降低开关损耗

反向恢复时间仅75ns,远优于普通整流二极管(通常≥200ns),可有效减少开关过程中的反向恢复电流,降低电路功耗,适配几十kHz至几百kHz的高频开关应用(如DC-DC转换器)。

2. 低正向压降提升效率

3A工作电流下正向压降仅1.7V,比传统快恢复二极管(如FR307)低0.1~0.2V,导通损耗减少约10%,适合低功耗设计(如LED驱动电源、笔记本适配器)。

3. 强浪涌能力保障可靠性

非重复峰值浪涌电流达100A(8.3ms),可承受电源开机、负载突变等瞬间大电流冲击,避免器件损坏,提升电路抗干扰能力。

4. 宽温范围适应恶劣环境

工作结温覆盖-55℃+150℃,满足工业级(-40℃+85℃)、车载级(-40℃~+125℃)的温度要求,可应用于户外储能、汽车辅助电源等场景。

四、典型应用场景

HS3MB的参数匹配中功率高频电路需求,典型应用包括:

  1. 开关电源:AC-DC适配器(笔记本、显示器)、DC-DC转换器(车载充电、LED驱动)的续流二极管、整流桥臂;
  2. 逆变与UPS:小型太阳能逆变器、UPS电源的功率回路,利用快恢复特性降低开关损耗;
  3. 工业控制:电焊机、变频器、伺服驱动器的续流/整流元件,适应宽温与浪涌冲击;
  4. 家电与消费电子:变频空调、洗衣机、机顶盒等设备的电源模块,兼顾小型化与可靠性;
  5. 新能源:小型储能系统、电动车辅助电源的低功率回路,平衡效率与成本。

五、使用注意事项

为保障HS3MB长期可靠工作,需注意以下要点:

  1. 参数限制:反向耐压不超1000V,平均正向电流不超3A,非重复浪涌电流不超100A(8.3ms),避免过压过流;
  2. 散热设计:工作结温不超150℃,需通过PCB铜箔(≥2oz)、散热片等方式优化散热,避免局部过热;
  3. 焊接工艺:回流焊峰值温度≤260℃(时间≤10s),手工焊接温度≤350℃(时间≤3s),防止封装损伤;
  4. 静电防护:器件为静电敏感元件,操作时需佩戴静电手环、使用防静电工作台,避免击穿;
  5. 存储条件:存储温度-55℃~+150℃,湿度≤85%RH,避免长期暴露于潮湿环境。

HS3MB凭借高性价比、快恢复特性与宽温适应性,成为中功率高频电路的优选器件,可满足工业、消费电子、新能源等多领域的设计需求。

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
