RV2E014AJT2CL 产品概述

一、产品简介

RV2E014AJT2CL 是 ROHM(罗姆)推出的一款小功率 N 沟道增强型 MOSFET,采用超小型封装 DFN1006-3。器件额定漏源电压为 30V,适用于开关和低电压电源分配场合。该器件单片封装、性能稳定,适合空间受限的便携式和消费类电子产品。

二、主要参数

  • 类型:N 沟道 MOSFET(增强型)
  • 数量:1 个
  • 漏源电压 Vdss:30 V
  • 连续漏极电流 Id:700 mA
  • 导通电阻 RDS(on):290 mΩ @ VGS = 4.5 V(测试电流 1.4 A)
  • 功耗 Pd:400 mW
  • 阈值电压 VGS(th):典型 1.5 V
  • 输入电容 Ciss:105 pF @ 15 V
  • 封装:DFN1006-3(超小型,适合高密度 PCB 布局)
  • 制造商:ROHM(罗姆)

三、主要特性与优势

  • 小体积:DFN1006-3 封装极度节省 PCB 面积,适用于空间受限的设计。
  • 逻辑电平驱动倾向:阈值电压典型值 1.5 V,且在 VGS = 4.5 V 时 RDS(on) 指标明确,便于与常见微控制器电平配合(推荐在 4.5 V 驱动下使用以获得标称导通阻抗)。
  • 低至中等功耗:Pd = 400 mW,搭配合理的 PCB 散热设计,可在近 0.7 A 的连续电流下稳定工作。
  • 中等输入电容:Ciss = 105 pF,在中低频率开关应用中具备良好响应,栅极驱动能量适中,便于实现较低开关损耗。

四、典型应用场景

  • 便携式设备中的低侧开关与电源切换
  • 电池管理与电源路径选择(电流需求不高的分支)
  • LED 驱动电路(小电流 LED 阵列)
  • 逻辑电平可控的电源分配与信号开关
  • 需要极小 PCB 占用的传感器和模块电源开关

五、封装与热管理建议

DFN1006-3 为超小尺寸封装,热阻相对较高,器件的实际热性能强烈依赖 PCB 铜厚和焊盘设计。建议:

  • 在器件下方和焊盘周围使用尽可能大的铜箔面积以帮助散热;
  • 若电流接近额定 700 mA,应考虑加大铜箔或多层过孔以导出热量;
  • 留意导通损耗计算:Pcond ≈ I^2 × RDS(on)。例如 I = 0.7 A 时 Pcond ≈ 0.7^2 × 0.29 ≈ 0.142 W,低于 Pd 但需考虑环境温度及其他损耗(开关损耗等)。
  • 开关频率上限受 Ciss 及驱动能力影响,若频繁快速开关,需评估栅极驱动能量及由此产生的开关损耗。

六、选型与注意事项

  • 若系统栅极驱动仅 2.5 V,应首先验证在该 VGS 下的 RDS(on) 与损耗;RV2E014AJT2CL 在 4.5 V 条件下给出 RDS(on) 规格,低电压驱动时导通阻抗会明显上升。
  • 对瞬态过压、反向恢复和浪涌电流要有保护措施(TVS、限流或软起动),以免超过器件的极限应力。
  • 关注 PCB 组装和焊接工艺,超小封装对回流焊曲线和焊盘设计敏感。
  • 若需要在高脉冲或高温环境长时间工作,请参考详细数据手册进行热降额和脉冲能力评估。

RV2E014AJT2CL 以其超小封装与适中的电气性能,为空间受限且电流需求在数百毫安级的应用提供了可靠的 MOSFET 解决方案。选择时应结合实际驱动电压、开关频率和 PCB 散热设计,确保器件工作在安全的热与电应力范围内。

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
