MMBD4448HTW-TP 表面贴装二极管阵列产品概述

MMBD4448HTW-TP是一款由MCC(美微科)推出的3通道独立式表面贴装二极管阵列,专为中小功率、高速开关、高密度PCB设计场景优化。产品兼具小封装、低功耗、高速恢复等核心优势,广泛适配便携电子、通信模块、消费电子等领域的小信号处理与电源辅助需求。

一、核心定位与设计亮点

该产品采用3个独立二极管集成设计,在极小封装内实现多路小电流整流/开关功能,解决了传统离散二极管占用空间大、焊接效率低的问题。其核心设计目标是:

  • 满足高频小信号的快速切换需求(如通信射频前端);
  • 适配电池供电设备的低功耗要求(如智能穿戴);
  • 支持高密度PCB布局(如便携设备内部紧凑空间)。

二、关键电气参数解析

每个独立二极管的参数经过优化,平衡了性能与可靠性:

1. 电流与电压能力

  • 平均整流电流(Io):250mA/管,可稳定承载小功率负载(如传感器供电、LED驱动);
  • 最大反向电压(Vr):80V,覆盖5V/12V/24V等中低电压系统(如车载USB辅助电路);
  • 反向泄漏电流(Ir):仅100nA(@70V),漏电流极小,可显著降低待机功耗(尤其适合电池设备)。

2. 高速开关特性

  • 反向恢复时间(trr):仅4ns,远低于行业“快速恢复二极管”(≤500ns)的定义,能有效抑制高频切换时的反向电流尖峰,减少电磁干扰(EMI),保证信号完整性(如WiFi模块的射频信号处理)。

3. 功耗与耐热性

  • 正向压降(Vf):1.25V(@150mA),在快速恢复二极管中处于合理范围,兼顾开关速度与效率;
  • 最大结温:150°C,可适应环境温度较高的场景(如便携设备内部散热空间有限的情况),长期工作稳定性好。

三、封装与安装特性

产品采用SOT-363封装(又称SC-88),属于6引脚表面贴装型小封装:

  • 尺寸极小(约2.0×1.25mm),适合高密度PCB布局;
  • 引脚间距合理,兼容自动化贴装设备,量产效率高;
  • 封装材料耐热性好,可通过回流焊等标准工艺焊接。

四、典型应用场景

因小封装、高速、低功耗的特点,该产品广泛适用于以下场景:

1. 便携电子设备

  • 智能穿戴(手环、手表):传感器供电整流、蓝牙模块信号处理;
  • 便携音箱/耳机:电池充电辅助电路、音频信号整流。

2. 通信与射频模块

  • WiFi/蓝牙/LoRa模块:射频前端信号整流、高速开关控制;
  • 小型基站辅助电路:低电压电源转换、信号滤波。

3. 消费电子辅助电路

  • 遥控器:红外信号驱动、按键电路开关;
  • 小型家电:电源指示灯控制、低压保护电路。

4. 汽车电子低电压部分

  • 车载USB充电接口:过压保护辅助、数据信号整流;
  • 仪表盘小型显示:背光驱动、低电压控制。

五、品牌与可靠性

该产品由国内知名半导体厂商MCC(美微科)出品,MCC在分立器件领域拥有10+年研发制造经验,产品符合:

  • RoHS环保标准(无铅无卤);
  • 高低温循环、湿度老化等可靠性测试;
  • 消费电子/通信行业的量产质量要求。

总结

MMBD4448HTW-TP通过“3管集成+小封装+高速恢复”的设计,精准匹配中小功率高速应用的需求,既解决了空间紧凑问题,又保证了信号完整性与低功耗,是便携电子、通信模块等领域的高性价比选择。

Sourcing availability signal

Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.

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.

Replenishment inquiry Typical RFQ workflow
