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:
SF26G的参数围绕“高频高效”设计,核心指标解析如下:
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。
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。
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。
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。
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。
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。
SF26G采用DO-15轴向引线封装,具备以下优势:
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。
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:
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。
Request for quote
Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
