SF58G是钜兴(JUXING) 推出的一款中功率快恢复/高效率二极管,针对高频开关电源、逆变器等需要高效整流、低损耗的应用场景优化设计,兼具高速开关特性与可靠的电气性能,适合工业控制、新能源等领域的中等功率电路需求。
SF58G定位于中等功率高频整流/续流应用,核心解决“高频下低损耗”与“可靠耐压”的平衡问题:
典型应用聚焦于:开关电源二次侧整流、光伏逆变器续流、电机驱动回路、UPS电源模块等。
SF58G的电气参数围绕“高效、可靠、高速”三大核心设计,关键指标如下:
在额定平均电流5A下,正向压降仅1.65V——这一数值在快恢复二极管中属于低损耗水平,相比同类产品可降低约10%~15%的导通功率损耗(导通损耗=I×Vf),直接提升整机效率。
反向恢复时间Trr=35ns:快恢复二极管的核心指标,直接影响高频电路的开关损耗——35ns的恢复时间可将高频下的开关损耗降低30%以上,适配100kHz以内的开关频率(如LLC谐振电源)。
非重复峰值浪涌电流Ifsm=150A:可承受开机瞬间、负载突变等场景的大电流冲击(持续时间≤10ms),有效避免浪涌导致的器件损坏,提升电路可靠性。
SF58G采用DO-27插件封装,具备以下优势:
SF58G的可靠性设计覆盖全工况:
SF58G作为一款性能均衡的快恢复二极管,以低导通损耗、高速开关、宽温可靠为核心优势,覆盖中等功率高频电路的主流应用场景。JUXING的工业级品质保障,使其成为开关电源、新能源、工业控制等领域的高性价比选择。

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.
