RS2M是FOSAN(富信) 推出的快恢复/高效率功率整流二极管,属于中小功率高频整流器件范畴。相比普通硅整流管(如1N4007系列),其核心优势在于短反向恢复时间与低正向压降的结合,既满足高压场景的耐压需求,又适配高频开关应用的效率要求,是开关电源、逆变器等领域的高性价比选择。
RS2M的核心参数精准匹配中小功率高频整流场景,具体特性如下:
导通损耗是整流器件的核心损耗之一,RS2M在额定电流2A下仅1.3V的正向压降,相比同类高压快恢复管(部分竞品Vf≥1.4V@2A),导通损耗可降低约7%(计算:2A×1.3V=2.6W vs 2A×1.4V=2.8W),长期工作时温升更低、效率更高。
1kV的反向耐压覆盖了多数AC-DC转换的高压侧需求(如市电整流后的峰值电压约311V,1kV余量充足),同时适配部分高压逆变器、工业电源的电压等级,避免击穿风险。
额定2A的直流电流能力,满足中小功率应用(如100W以内开关电源、50W车载充电器)的持续工作需求,同时具备一定的过载裕量(短时间峰值电流可更高)。
反向恢复时间是快恢复管的关键指标,直接影响高频开关损耗。RS2M的500ns(纳秒级)比普通整流管(Trr>1μs)快一倍以上,在100kHz开关频率下,可将反向恢复损耗降低约50%,显著提升电源转换效率。
宽温范围覆盖了工业级环境(如户外逆变器、车载电子)的极端温度需求,低温下不失效,高温下(150℃结温)仍能稳定工作,可靠性更强。
RS2M采用SMA封装(DO-214AC),属于小型贴片封装,具备以下优势:
RS2M的参数特性使其广泛适用于以下场景:
FOSAN(富信)是国内专注功率半导体器件的厂商,RS2M的品质管控具备以下特点:
RS2M通过优化的芯片设计与封装工艺,平衡了高压、大电流、快恢复、低损耗四大核心需求,是中小功率高频整流应用的高性价比选择。其宽温范围与可靠品质,可满足工业、车载、消费电子等多领域的使用要求,适配自动化生产与小型化设计趋势。

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.
