2N7002 为单只 N 沟增强型小信号 MOSFET,ON Semiconductor(安森美)出品,采用 SOT-23-3L 小型封装。该器件设计用于低功耗开关与信号级别转换场合,典型应用包括数字接口驱动、低电流开关、负载断开与快速开关场景。器件在 60V 漏源耐压范围内,结合较小的输入/输出电容,使其在高电压与高速切换要求并存但电流需求不大的场合表现良好。
以上参数反映了该器件为低功耗、小信号场合而优化的特性:高压耐受、较大的 RDS(on) 与较小的封装功耗限制决定其更适合信号级与小电流开关应用,而非大功率传导场合。
SOT-23-3L 小封装适合表贴自动化装配,但热阻较高。推荐 PCB 上为器件下方和引脚处预留适量铜面积以提升散热。若设计接近器件功耗上限,应考虑更大封装或降额使用。
总结:2N7002(ON)是一款适用于中高电压、低电流、小信号开关与接口转换的经济型 N 沟 MOSFET。它在 SOT-23 封装下兼具高压耐受与低寄生电容的优点,但受限于较高的 RDS(on) 与有限的持续电流与功耗能力,需在设计时结合驱动电压与热管理做出合适的选型与布线安排。

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.
