PNM3FD20V1E 产品概述

一、产品简介

PNM3FD20V1E 是芯导(Prisemi)推出的一款微型 DFN-3L (1.0 × 0.6 mm) 封装 N 沟道 MOSFET。该器件针对空间受限、低功耗开关应用优化,提供快速开关性能、较低导通电阻与低栅极驱动能耗的平衡,适用于便携设备、电源路径控制与小电流负载开关等场景。

二、主要电气参数

  • 类型:N 沟道 MOSFET
  • 漏—源耐压 Vdss:20 V
  • 连续漏极电流 Id:1 A
  • 导通电阻 RDS(on):450 mΩ @ Vgs = 1.8 V
  • 功耗 Pd:300 mW
  • 阈值电压 Vgs(th):900 mV(典型)
  • 总栅极电荷 Qg:1 nC @ 4.5 V
  • 输入电容 Ciss:48 pF
  • 反向传输电容 Crss:10 pF
  • 工作温度范围:-55 ℃ ~ +150 ℃
  • 封装:DFN-3L (1 × 0.6 mm)

三、性能亮点

  • 极低的栅极电荷(Qg = 1 nC)与较小 Ciss(48 pF),使得栅极驱动能耗低,适合电池供电和高频开关场合;
  • Crss(10 pF)较小,有利于降低 Miller 效应,提高开关速度和抗干扰性能;
  • 在 Vgs = 1.8 V 下给出 RDS(on) 规格,便于与低电平门驱动兼容(注意确认系统实际驱动电压以达到所需导通电阻)。

四、热与功耗注意事项

  • 标称耗散功率 Pd = 300 mW,封装非常小,导热能力有限。按 RDS(on) = 0.45 Ω 计算,若持续通过 1 A 电流,导通损耗约为 I^2·R = 0.45 W,已超出器件 Pd 额定值,不能在此条件下长期工作;
  • 建议在实际应用中限制连续电流、采用脉冲工作或通过 PCB 铜箔加大散热面积来降低结温;在布局上优先使用较大铜箔、多个过孔或接地平面以改善热耗散。

五、典型应用场景

  • 低压电源路径选择与负载开关(电池管理、电源复用);
  • 便携设备中的小电流 DC-DC 输出断开或同步整流前端开关(低功率级);
  • 信号级开关、低侧开关、保护电路和功率路由控制;
  • 对空间、成本、驱动能耗敏感的高频或中频开关场合。

六、布局与使用建议

  • 门极驱动:若要达到标称 RDS(on) 请确保 Vgs ≈ 1.8 V;若系统驱动电压更高,请查阅完整数据手册确认更高 Vgs 下的 RDS(on) 及最大 Vgs 限值;
  • 门极串联电阻(例如 4.7–47 Ω)可抑制振铃与限流;加上门极下拉(100 kΩ)保证上电或断电时 MOSFET 关闭;
  • PCB 布局:尽量增大焊盘铜箔面积,缩短高电流回路长度,若可能在器件下方布置热铜垫并与内层散热平面焊接;
  • 热限制:对连续运行场合务必做热仿真与实际测温验证,避免长期在接近 Pd 条件下工作。

七、选型与采购提示

PNM3FD20V1E 适合对体积与驱动能耗有严格要求的低功耗开关应用。采购或设计前请务必参考完整数据手册,确认最大 Vgs、脉冲电流能力、封装引脚图与推荐焊盘,并在电流/功率边界处预留安全余量。品牌:Prisemi(芯导);封装:DFN-3L (1×0.6 mm)。

若需,我可以根据具体电路条件(工作电流、占空比、环境温度、PCB 板型)帮您进行更精确的损耗与结温估算,并给出布局与散热的详细建议。

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
