WPM2093-3/TR 产品概述
一、产品简介
WPM2093-3/TR 是 WILLSEMI（韦尔）推出的一款 P 型绝缘栅场效应管（P‑MOSFET），采用超小型 SOT‑723 封装，面向低压小功率场合的高端开关与电源管理应用。器件耐温范围宽（-55℃ 至 +150℃），适用于工业级与便携设备的严格环境要求。
二、主要特性
- P 型 MOSFET，高端开关方便做电源路径控制与负载断开
- 漏源电压 Vdss = 20V，适合常见 5V 及更低电压系统
- 导通电阻 RDS(on) = 360mΩ（Vgs = 4.5V），在小电流场合有良好导通性能
- 连续漏极电流 Id ≈ 910mA，适合 1A 量级负载
- 耗散功率 Pd = 450mW，需要合理 PCB 散热设计
- 低门极电荷 Qg = 1.1nC（4.5V），切换损耗低，适合电池供电与快切换场合
三、关键电容与驱动特性
- 输入电容 Ciss = 104pF，输出电容 Coss = 25pF，反向传输电容 Crss = 19pF
- 阈值电压 Vgs(th) = 1V（Ib=250µA）——易被驱通但需保证足够门源电压摆幅
- 低 Qg 与中等 Coss 有利于降低驱动能耗和开关损耗，适用于频率不高的开关场景
四、典型应用
- 便携设备电源开关与电源路径选择（高端开关）
- 电池管理与负载切换、反向电流阻断
- USB/Type‑C 电源控制与外设供电开关
- 低功率 DC‑DC 高端开关与电源保护电路
五、设计与布局建议
- 作为 P 型高端开关时，源连接到正电源，驱动需将栅极拉低（相对源）以导通；关闭时将栅极拉回源电位。注意 Vgs 极性为负值。
- 采用适当的栅阻（例如几十欧姆）可以抑制振铃并限制浪涌电流；在高开关频率应用中应评估 Qg 与驱动器能力。
- SOT‑723 封装热阻较大，建议在 PCB 上为漏极/焊盘留足够铜箔面积以增强散热，并靠近去耦电容布局，缩短高电流回路长度。
- 对于持续接近额定 Pd 或 Id 的应用，应进行热仿真与降额设计，避免长期高温运行。
六、可靠性与使用注意
- 器件工作温度范围宽（-55℃~+150℃），适合工业及高温环境使用；但在高温、高功耗条件下需通过 PCB 设计与降额使用来保证长期可靠性。
- 在含有浪涌或反向瞬态的应用中，应配合合适的瞬态抑制器（TVS）、限流或软启动措施，保护器件不过载。
- 对于需要更低导通损耗或更高电流的场合，建议评估其他 N 型/更大封装型号以获得更低 RDS(on)。
WPM2093-3/TR 以其小封装、低门极电荷与适中的导通电阻，在 5V 及以下、对尺寸与功耗敏感的高端开关与电源管理场合中具有良好的性价比。请选择合适的器件驱动与 PCB 散热方案以发挥其最佳性能。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
