UT4421G-SO8-R 是友顺(UTC)生产的一款 P 沟道场效应管(P-MOSFET),封装为 SOP-8,适用于 60V 档位的高侧开关与电源管理场合。器件在 VGS = 10V 驱动下导通电阻仅 40mΩ(典型),连续漏极电流 6.2A,能够满足中低功率开关与保护应用的需求。单颗器件常见销售包装为 1 个/件,方便样品与小批量使用。
UT4421G-SO8-R 适合做 60V 档位的高侧开关与保护器件,若应用中要求更低的 RDS(on) 或更高的连续电流,应考虑更大封装或更低阻型 MOSFET;若开关频率很高,则需关注 Qg 与 Coss 对开关损耗的影响。最终设计前请参考 UTC 提供的完整数据手册与典型特性曲线,以确认温度、脉冲条件和极限参数。
如需器件封装图、引脚定义或更详细的温度—电流限制曲线,可进一步查阅 UTC 官方资料或索取样片试验验证。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
