GR2MA快恢复/高效率二极管产品概述

GR2MA是扬杰科技(YANGJIE)推出的独立式快恢复/高效率二极管,采用SMA(DO-214AC)表面贴装封装,兼具高压耐受、低损耗、快恢复等核心特性,适配中高压高频整流及中小功率电源转换场景。

一、核心电气参数概览

GR2MA的参数设计围绕高压、大电流、高效能三大核心,关键指标如下:

  • 正向压降(Vf):1.3V@2A(典型值),远低于普通硅整流管(通常1.7V以上),显著降低导通损耗,提升能量转换效率;
  • 直流反向耐压(Vr):1kV,满足中高压电路的反向阻断需求,避免击穿风险;
  • 最大整流电流(If):2A(持续直流),可稳定承载2A以内的连续工作电流,适配中小功率电源;
  • 反向恢复时间(Trr):500ns,属于快恢复二极管范畴,比普通整流管(μs级)快一个数量级,减少开关损耗与电磁干扰;
  • 反向漏电流(Ir):5μA@1kV(典型值),漏电流极低,反向阻断性能稳定,进一步降低反向功耗;
  • 非重复峰值浪涌电流(Ifsm):50A(8.3ms正弦半波),可抵御瞬间过流冲击,提升电路抗干扰能力;
  • 工作结温范围:-55℃~+150℃,覆盖工业级宽温环境,适应极端温度场景。

二、封装形式与物理特性

GR2MA采用SMA(DO-214AC)表面贴装封装,是中小功率二极管的主流小型化封装,具备以下特点:

  • 体积紧凑:封装尺寸约2.0mm×3.5mm×1.5mm(长×宽×高),无引脚/短引脚设计,适合高密度PCB布局,节省电路板空间;
  • 贴装便捷:适配自动化SMT工艺(回流焊、波峰焊),可批量生产,提升制造效率;
  • 独立式配置:单管独立封装,无并联/串联设计,电路设计灵活,便于按需组合;
  • 散热适配:虽体积小,但最大结温达150℃,配合PCB铜箔铺地等散热设计,可满足一般应用的散热需求。

三、关键性能优势

GR2MA的性能优势集中体现为高效、高速、可靠,具体如下:

  1. 高效率:低正向压降(1.3V@2A)减少导通损耗,连续大电流工作时能效提升明显,适配对效率敏感的电源产品;
  2. 快恢复特性:500ns反向恢复时间,降低开关电路的反向恢复损耗,减少EMI干扰,适配100kHz以下高频应用;
  3. 高压耐受:1kV反向耐压覆盖中高压场景,避免电压击穿导致的电路故障,提升系统稳定性;
  4. 低漏电流:5μA@1kV反向漏电流,高压反向偏置下仍保持低功耗,适合精密电路;
  5. 宽温适应性:-55℃~+150℃结温范围,满足户外设备、工业控制等极端温度环境;
  6. 抗浪涌能力:50A非重复浪涌电流,抵御电源启动/外部干扰的过流冲击,保护电路器件。

四、典型应用场景

GR2MA的参数特性使其适用于以下场景:

  • 开关电源次级整流:AC-DC适配器、DC-DC转换器的次级整流,快恢复减少高频损耗;
  • 逆变器辅助电路:太阳能逆变器、UPS的辅助电源,高压耐受与宽温适配户外/工业环境;
  • 高压小电流整流:仪器仪表、医疗设备的高压供电,低漏电流保障精密测量;
  • 电机驱动控制:小型直流/步进电机的续流二极管,快恢复减少换向电压尖峰;
  • 消费电子电源:机顶盒、路由器、智能家居设备的电源模块,SMA封装适配轻薄化需求。

五、品牌与可靠性保障

GR2MA由扬杰科技生产,扬杰科技是国内功率半导体龙头厂商,产品具备以下可靠性:

  • 环保合规:符合RoHS 2.0标准,无有害物质;
  • 工艺成熟:采用硅外延工艺,参数一致性与稳定性高;
  • 可靠性测试:经过温度循环、湿度老化、浪涌冲击等测试,满足工业级要求;
  • 设计支持:提供详细参数曲线(Vf随电流/温度变化、Trr随电压/电流变化),便于电路设计与仿真。

综上,GR2MA以高压、高效、快恢复特性结合小型化封装,成为中小功率电源、工业控制等领域的理想选择。

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
