WPM2083-3/TR 产品概述

一、产品简介

WPM2083-3/TR 是 WILLSEMI(韦尔)推出的一款 P 沟道场效应晶体管(P‑MOSFET),封装为 SOT‑23,适用于低压电源路径控制与小功率开关场合。器件耐压 20V,单通道设计,能够在空间受限的消费电子与工业控制电路中发挥作用。

二、主要性能参数

  • 类型:P 沟道 MOSFET(单通道,数量 1)
  • 漏源电压 Vdss:20V
  • 连续漏极电流 Id:2.2A
  • 导通电阻 RDS(on):150mΩ @ Vgs = 2.5V
  • 阈值电压 Vgs(th):1V @ Idss = 250µA
  • 栅极电荷 Qg:5.8nC @ Vgs = 4.5V
  • 输入电容 Ciss:486pF;输出电容 Coss:62pF;反向传输电容 Crss:48pF
  • 耗散功率 Pd:800mW
  • 工作温度范围:-55℃ ~ +150℃
  • 品牌:WILLSEMI(韦尔),封装:SOT‑23

三、主要特性与优势

  • 逻辑电平驱动友好:RDS(on) 在 Vgs = 2.5V 下为 150mΩ,便于直接由 2.5V 或更高电平逻辑驱动实现低压侧的导通控制。
  • 低门极电荷:Qg = 5.8nC(@4.5V)对中低频切换场合有利,减少驱动损耗并降低驱动器尺寸。
  • 小电容特性:Ciss/Coss/Crss 数值适中,有利于在开关瞬态中控制损耗与稳定性。
  • 宽温度范围与紧凑封装:-55 ~ +150℃ 的工作温度覆盖工业级应用,SOT‑23 有利于占板空间受限的应用。

四、典型应用场景

  • 电池供电设备中的电源路径或负载开关(高端 P‑MOSFET 实现正向断开/反向阻断)。
  • 便携式设备、移动终端、电源管理模块中的低功耗开关。
  • 热插拔、反接保护与电源切换电路。
  • 低压 DC‑DC 升降压电路中的高端开关(注意功耗与散热限制)。

五、驱动与热管理建议

  • 作为 P 型器件,栅极相对于源要拉低才能导通(Vgs 为负值),驱动时需考虑系统最高供电电压与门级驱动电平,避免超过器件 Vgs 极限。
  • 按 RDS(on) 计算导通损耗:Pd(on) ≈ I^2·RDS(on),例如接近额定电流时损耗明显(2A²×0.15Ω ≈ 0.6W),接近或超过器件 Pd(800mW)时需外加散热或降低电流工作点。
  • 开关损耗可由 Qg 与开关频率估算:Pdrive ≈ Qg × Vdrive × f。对高频应用建议优化门极驱动或采用缓冲/限流电阻以抑制振铃与电磁干扰。
  • SOT‑23 封装热阻较高,建议在 PCB 上增加散热铜箔面积与热 vias,并留意焊盘布局以改善热扩散。

六、封装与可靠性

SOT‑23 小型封装适合体积受限应用,可靠性与焊接工艺成熟。推荐在生产与可靠性验证阶段进行热循环与电应力测试以确认在目标应用中的长期稳定性。

七、选型提醒

在评估此型号时,请关注实际工作电流与平均/冲击电流峰值,结合 RDS(on) 与 Pd 做热裕度计算;若系统电流接近或超过器件极限,建议选择更低 RDS(on) 或更高功耗等级的器件。综合考虑驱动电平、开关频率与 PCB 散热设计,方能充分发挥 WPM2083-3/TR 的性能。

总结:WPM2083-3/TR 以其 20V 耐压、逻辑电平导通特性与紧凑 SOT‑23 封装,适合低压电源路径控制与电源管理场合,但在高电流或高开关频率应用中需谨慎做热和驱动设计。

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
