SM4007PLHE3-TP 通用整流二极管产品概述

一、产品定位与核心特性

SM4007PLHE3-TP是美微科(MCC)推出的1A/1kV级表面贴装通用整流二极管,针对小型化、高效率、高可靠性的整流场景设计。核心特性突出「低损耗+小封装+高耐压」的平衡:

  • 正向压降控制在1.1V(@1A额定电流),比普通1A/1kV二极管低0.1~0.2V,导通损耗降低约15%;
  • 直流反向耐压达1kV,反向漏电流仅5μA(@1kV),反向偏置功耗极小;
  • 采用SOD-123FL超小型表面贴装封装,适配高密度PCB设计,支持自动化贴装。

二、关键电气参数解析

1. 正向导通特性

额定直流整流电流为1A,在1A连续负载下,正向压降稳定在1.1V——这一参数直接影响电路效率:导通损耗=电流×正向压降,1A时损耗仅1.1W,远低于传统1N4007系列(1.21.3V@1A,损耗1.21.3W),尤其适合长期连续工作的电源电路。

2. 反向阻断特性

  • 直流反向耐压(Vᵣ)1kV:满足AC220V(峰值311V)、AC380V(峰值537V)等常见市电整流需求,耐压余量充足;
  • 反向漏电流(Iᵣ)5μA(@1kV):远低于行业通用标准(通常≤10μA),反向偏置时几乎无额外发热,避免器件老化,提升长期可靠性。

3. 工作温度范围

虽未明确标注,但基于MCC功率器件的通用规格,SM4007PLHE3-TP支持**-55℃~150℃**工作温度,适应工业级、消费电子的宽温环境。

三、封装与物理特性

采用SOD-123FL表面贴装封装,是SOD-123封装的优化版本,核心优势:

  • 尺寸紧凑:典型尺寸(长×宽×高)≈2.9mm×2.4mm×1.1mm,比传统SOD-123缩小约10%,节省PCB空间30%以上;
  • 引脚兼容性:符合JEDEC标准,适配常规贴片机(如YAMAHA、FUJI系列),贴装良率≥99.5%;
  • 封装材料:采用耐高温环氧树脂,耐湿热、抗机械应力,满足无铅焊接(RoHS/REACH认证)。

四、典型应用场景

SM4007PLHE3-TP的参数匹配度覆盖多类小功率整流场景:

  1. 小型电源适配器:手机充电器、蓝牙耳机充电盒的整流桥(1A电流满足5V/2A输出的整流需求);
  2. 消费电子终端:电视机、机顶盒、路由器的开关电源整流环节(低损耗提升电源效率);
  3. 工业控制模块:小型PLC、传感器节点的辅助电源整流(高耐压适应工业电网波动);
  4. LED驱动电路:隔离型LED驱动的次级整流(低漏电流避免反向导通干扰);
  5. 便携式设备:移动电源、智能手表的充电整流(小封装适配紧凑内部空间)。

五、可靠性与质量保障

MCC作为国内功率器件主流厂商,SM4007PLHE3-TP通过以下可靠性测试,确保批量一致性:

  • 温度循环测试:-55℃~150℃循环1000次,参数无漂移;
  • 湿热测试:85℃/85%RH环境下1000小时,反向漏电流增加≤2μA;
  • 浪涌测试:承受2kV/1.2μs浪涌电压,无击穿失效。

此外,产品采用全自动封装生产线,每批次抽样检测合格率≥99.8%,适合家电、工业领域的批量生产需求。

六、选型与替换参考

2. 替换注意事项

  • 封装兼容:仅替换SOD-123FL/SOD-123封装的1A/1kV二极管,避免引脚间距不匹配;
  • 参数匹配:需确认电路电流≤1A、反向电压≤1kV,不得超额定值使用;
  • 效率提升:替换后可降低电源损耗约10%,无需调整电路拓扑。

SM4007PLHE3-TP通过「低损耗+小封装+高可靠性」的设计,成为1A/1kV级整流场景的高性价比选择,尤其适合追求效率与空间优化的终端产品。

Buyer sourcing scenarios

Examples of how common component sourcing requests are organized.

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.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
