扬杰HS3M整流二极管产品概述

扬杰HS3M是一款针对中小功率高频整流场景设计的表面贴装二极管,采用SMC(DO-214AB)封装,具备低导通损耗、快反向恢复、宽温适应性等核心优势,广泛应用于开关电源、LED驱动、适配器等领域。以下从核心定位、参数解析、封装设计、典型场景及应用注意事项展开说明。

一、产品核心定位与应用方向

HS3M定位于工业级快恢复整流二极管,聚焦需要兼顾「效率、速度、可靠性」的中等功率整流环节。其核心目标是解决普通硅整流二极管「反向恢复慢、损耗高」的痛点,同时以小型化封装匹配当前电子设备的轻薄化趋势。主要面向:

  • 开关电源次级整流
  • 中小功率LED驱动电源
  • 笔记本/手机充电器等适配器
  • 工业控制电路(电机驱动、传感器供电)

二、关键电性能参数深度解析

HS3M的参数设计平衡了「导通损耗、开关速度、耐压能力」,核心参数及意义如下:

  1. 导通特性:正向压降Vf=1.7V@3A
    远低于普通硅整流二极管(通常2V以上),可将导通损耗降低约15%,直接提升电源转换效率(如100W电源可减少约1.5W损耗)。
  2. 耐压能力:直流反向耐压Vr=1kV
    覆盖AC85-265V宽输入范围的整流需求(AC220V整流后峰值约311V,留有充足裕量),避免过压击穿风险。
  3. 电流承载:额定整流电流If=3A(持续)、非重复浪涌电流Ifsm=100A
    持续3A可满足多数中小功率负载(如10串10W LED);100A浪涌能力可应对开机瞬间、负载突变等冲击场景。
  4. 反向特性:反向漏电流Ir=5uA、反向恢复时间Trr=75ns
    • 5uA漏电流:反向绝缘性优异,减少静态损耗;
    • 75ns恢复时间:属于快恢复二极管范畴,适合100kHz以下高频开关电路,避免开关损耗过大。
  5. 温度特性:工作结温-55℃~+150℃
    符合工业级温度要求,可稳定工作于户外、高温车间等极端环境。

三、SMC封装设计与可靠性

HS3M采用SMC表面贴装封装,尺寸仅3.5×2.5×1.1mm,具有三大优势:

  1. 小型化适配:匹配超薄适配器、小型LED驱动等高密度PCB设计需求;
  2. 散热优化:封装采用高导热环氧材料,配合PCB铜箔可有效散发热量,支持150℃结温下的长期稳定工作;
  3. 可靠性保障:扬杰采用成熟的键合与塑封工艺,焊接可靠性符合工业级标准,抗机械应力、耐潮湿能力强。

四、典型应用场景举例

  1. 开关电源次级整流:100W以内AC-DC开关电源中,HS3M的快恢复特性可减少开关损耗,提升效率至85%以上;
  2. LED驱动电源:3A电流可驱动多串LED(如12串10W灯珠),1kV耐压满足宽输入电压范围;
  3. 笔记本充电器:SMC封装匹配充电器的轻薄化设计,浪涌能力应对插拔瞬间的冲击;
  4. 工业控制电路:宽温范围适应-20℃~+85℃的工业环境,稳定支撑电机驱动、传感器供电等环节。

五、应用选型与注意事项

  1. 电流降额:建议持续工作电流不超过2.5A(留20%余量),避免长期过流导致结温过高;
  2. 电压裕量:实际反向峰值电压建议不超过800V,避免过压击穿;
  3. 散热设计:PCB焊盘采用1oz铜箔,面积≥10mm²,必要时增加散热铜皮;
  4. 焊接工艺:回流焊峰值温度≤260℃(时间≤10s),避免过温损坏;
  5. 浪涌防护:长期频繁浪涌场景建议并联TVS二极管,进一步提升可靠性。

扬杰HS3M凭借平衡的性能参数、小型化封装及高可靠性,成为中小功率整流场景的优选器件,尤其适合需要国产化替代的客户需求。

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
