RS2M快恢复/高效率二极管产品概述

一、产品核心定位与类别

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。

二、关键电气参数详解

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:

1. 正向压降(Vf):1.3V@2A

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。

2. 直流反向耐压(Vr):1kV

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。

3. 持续整流电流(If):2A

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)。

4. 反向恢复时间(Trr):500ns

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。

5. 工作结温范围:-65℃~+150℃

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。

三、封装与物理特性

RS2M采用SMA封装(DO-214AC),属于小型贴片封装,具备以下优势:

  • 体积紧凑:尺寸约2.7mm×1.7mm×1.1mm,节省PCB空间,适配小型化电源设计;
  • 贴装便捷:符合SMD自动化贴装工艺,适合批量生产;
  • 散热可靠:贴片封装的热阻(约15℃/W)优于部分直插封装,配合PCB铜箔可有效散发热量;
  • 引脚标识清晰:色环端为阴极,便于焊接与电路识别。

四、典型应用场景

RS2M的参数特性使其广泛适用于以下场景:

  1. 中小功率开关电源(SMPS):如手机充电器、LED驱动电源、笔记本电源适配器,高频整流时降低损耗;
  2. 逆变器:太阳能逆变器、车载逆变器的高压侧整流,宽温适应户外/车载环境;
  3. 不间断电源(UPS):整流与续流环节,提升转换效率;
  4. 工业控制电路:电机驱动的续流二极管、PLC电源模块,宽温满足工业现场需求;
  5. 消费电子:智能家电(如空调、电视)的电源整流,贴片封装适配小型化设计。

五、品牌与品质保障

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:

  • 环保合规:符合RoHS、REACH标准,无铅封装;
  • 可靠性测试:通过高低温循环(-65℃~+150℃)、反向耐压测试、寿命加速测试等,参数离散性小(Vf偏差≤0.1V);
  • 批量一致性:适合工业级批量应用,避免因器件参数波动导致的电源效率不稳定。

总结

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。

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.
