SF26G 快恢复二极管产品概述

一、产品核心定位与应用场景

SF26G是扬杰科技(YANGJIE)推出的独立式快恢复/高效率二极管,属于中高速功率整流器件,专为中小功率高频开关电路设计。其核心优势在于低导通损耗与快速反向恢复特性,可有效降低开关过程中的能量损耗,提升电路效率。

该产品广泛适用于以下场景:

  • 开关电源:20W-100W AC-DC适配器、DC-DC转换器的整流/续流回路;
  • 逆变器:小型家用/车载逆变器(100W-500W)的直流-交流转换环节;
  • LED驱动:恒流/恒压LED驱动电源的高频整流部分;
  • 家电控制:电磁炉、微波炉等家电的电源整流/续流电路;
  • 工业电源:小型PLC、传感器模块的辅助电源整流。

二、关键电气参数深度解析

SF26G的参数围绕“高频高效”设计,核心指标解析如下:

  1. 正向压降(Vf):1.3V@2A
    在额定整流电流(2A)下,正向导通压降稳定在1.3V,直接减少导通损耗,提升电源转换效率,适合连续负载工况。

  2. 直流反向耐压(Vr):400V
    额定反向阻断电压400V,满足市电(220VAC)整流后(峰值约310V)的安全余量,避免反向击穿风险。

  3. 连续整流电流(IF):2A
    额定连续正向电流2A,可稳定承载中小功率电路负载,环境温度较高时可适当降额使用。

  4. 反向漏电流(Ir):5μA@400V
    反向漏电流仅5μA(25℃时),远低于行业标准,反向阻断性能优异,长期工作可靠性高。

  5. 反向恢复时间(Trr):35ns
    快恢复二极管的核心指标,35ns的恢复时间比普通整流管(如1N4007>30μs)快近千倍,大幅降低高频开关时的“反向恢复损耗”,适配几十kHz至几百kHz的开关频率。

  6. 工作结温范围:-55℃~+150℃
    宽温范围覆盖工业级环境(户外低温、设备内部高温),满足严苛工况下的稳定运行。

三、封装与可靠性设计

SF26G采用DO-15轴向引线封装,具备以下优势:

  • 安装便捷:轴向引线设计,适合通孔焊接,可直接插入PCB板;
  • 散热可靠:封装热阻满足2A电流下的结温控制(150℃以内),若负载电流接近2A,建议PCB铜箔宽度≥1.5mm;
  • 环境适应性:环氧树脂封装材料耐温、绝缘、抗潮湿,符合RoHS环保标准。

扬杰科技对产品进行了严格可靠性测试:高低温循环(-55℃~150℃,1000次)、湿热测试(85℃/85%RH,1000h)、反向耐压老化(400V,1000h)等,确保长期稳定工作。

四、品牌与选型补充

扬杰科技是国内功率半导体龙头企业,产品覆盖二极管、三极管、MOS管等,广泛应用于消费电子、工业、汽车电子(AEC-Q101认证系列)等领域。SF26G作为其快恢复二极管经典型号,性价比突出。

选型替换建议:

  • 若需更高耐压(600V),可选择同系列SF26K;
  • 若需更大电流(3A),可选择SF36G;
  • 替代型号参考:ON Semiconductor FR206(Trr=50ns,略慢于SF26G)、国产某品牌FR204(耐压400V,Trr=40ns)。

五、注意事项

  1. 安装需注意极性(轴向引线,阴极通常有环标记);
  2. 焊接温度≤260℃(DO-15封装焊接限制);
  3. 若负载电流接近2A,建议配合散热片或加宽PCB铜箔。

SF26G凭借“高频高效、宽温可靠、安装便捷”的特点,成为中小功率开关电路的优选快恢复二极管。

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
