RS1MF是由钜兴(JUXING)电子推出的独立式快恢复/高效率二极管,采用SMAF表面贴装封装,专为小功率高频整流、开关电源等场景设计,兼顾效率与可靠性,满足工业级及消费电子的宽温应用需求。其核心定位可概括为:小体积、高效率、宽耐压、抗冲击,适配多场景下的稳定工作。
RS1MF的参数设计围绕“提升效率、降低损耗、增强可靠性”展开,核心参数解析如下:
正向压降(Vf)仅1.3V@1A,相比传统高压硅整流二极管(部分产品Vf达1.5V以上),在1A额定电流下保持低导通损耗,可有效减少电路发热,提升电源转换效率(尤其适合对效率敏感的便携设备)。
反向恢复时间(Trr)为500ns,属于快恢复二极管范畴——相比普通整流二极管(Trr通常为μs级),短恢复时间可大幅降低开关过程中的损耗,避免因恢复时间过长导致的EMI干扰与效率下降,尤其适合kHz级高频应用。
RS1MF的参数特性使其适用于以下核心场景:
作为高频整流管,500ns快恢复时间可降低开关损耗,1A电流满足手机、平板等小功率适配器的输出需求,1kV耐压适配AC-DC转换后的高压端,提升电源效率与稳定性。
-55℃~+150℃宽温范围适配车载环境(低温启动、高温暴晒),1kV耐压满足车载12V/24V系统的整流需求,抗浪涌30A可应对汽车点火瞬间的电流冲击。
在小型光伏逆变器、UPS电源中,RS1MF的快恢复特性可减少逆变过程中的能量损耗,1A电流支撑小功率输出,宽耐压适配不同输入电压等级。
低正向压降(1.3V@1A)可提升充电效率,减少充电时的发热;浪涌30A可承受电池接入瞬间的电流冲击,延长电池与充电电路寿命。
RS1MF采用SMAF表面贴装封装,具有以下优势:
此外,钜兴电子对产品进行了多轮可靠性测试(温循、浪涌冲击、反向耐压老化等),确保批量产品参数稳定,符合工业级应用标准。
RS1MF快恢复/高效率二极管凭借低导通损耗、快恢复时间、宽耐压宽温、抗浪涌等核心优势,成为小功率高频整流场景的优选器件,适用于开关电源、车载电子、电池充电等领域。其SMAF封装与独立式设计进一步提升了应用灵活性与可靠性,可满足多场景下的稳定工作需求。

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.
