SM4840PRL 是美国源芯(SPS)推出的一款双通道 N 沟道场效应管(Dual N‑MOSFET),封装为 SOP‑8。每通道额定漏源电压为 40V,连续漏极电流 6A,适用于中小功率开关和负载驱动场合。单器件内置两颗 N 沟道晶体管,便于板级布局和成组应用。
若系统要求更低的导通损耗或更高的功率耗散,应考虑更低 RDS(on) 或更大功耗封装(如 SO‑8 PowerPAK、DPAK 等)。在要求逻辑电平驱动(5V/3.3V)且低阻抗的场景,需验证在低 Vgs 下的 RDS(on) 性能。
型号:SM4840PRL
品牌:SPS(美国源芯)
封装:SOP‑8,双 N 沟道 MOSFET(2 个通道)
以上为 SM4840PRL 的概要介绍与应用建议,便于电路设计与系统选型。需要更详细的电气特性曲线或封装机械图纸,可参考厂商规格书或联系供应商获取完整资料。

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.
