1N4004 是一款通用整流二极管的型号,MSKSEMI(美森科)提供的该器件为独立式单个二极管封装,适用于一般功率整流和保护电路。其关键特点是耐压高、整流电流适中,适合各种交流到直流转换、反向保护与续流应用。
该型号由 DO-214AC(SMA)封装提供,为表面贴装形式,适合自动贴片与回流焊工艺。SMA 封装体积小、焊盘紧凑,有利于紧凑型电源板设计与批量生产。机械强度适中,但在安装与波峰/回流焊工艺中仍需注意热应力管理。
非重复峰值浪涌 Ifsm 为一次性冲击能力,不代表可长期重复承受的电流;频繁冲击会降低可靠性。封装及焊接过程请遵循供应商的回流曲线规范以避免热损伤。储存与使用时避免静电损伤(ESD)和反向高压瞬态超限,必要时并联适当抑制元件以保护二极管寿命。
综上,MSKSEMI 的 1N4004(DO-214AC/SMA)是一款面向通用整流与保护的可靠选择,适合中等电压(最高400V)与中小功率场景,在满足热设计与浪涌管理的前提下,可实现稳定长期工作。

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.
