1N4007 (M7) 产品概述
一、概述
1N4007 (M7) 是一款通用整流二极管，适用于高压整流与一般开关保护场合。本型号由 UMW（友台半导体）生产，采用 SMA（DO-214AC）表面贴装封装，兼顾高电压耐受与紧凑封装的应用需求。典型器件面向电源、电表、逆变器和保护电路等需要1kV级反向耐压的场景。
二、主要电气参数
- 正向压降 Vf：1.1V @ IF = 1A
- 直流反向耐压 Vr：1000V (1kV)
- 整流电流（额定）：800mA（连续）
- 反向漏电流 Ir：5µA @ VR = 1kV
- 非重复峰值浪涌电流 Ifsm：30A
- 工作结温范围：-55°C 至 +150°C
三、核心特性
- 高耐压：1kV 的反向耐压使其可用于高压整流和阻断回路。
- 低反向漏流：在额定耐压下反向电流低至数微安，有利于降低待机功耗与漏电引起的误动作。
- 良好浪涌承受：30A 的非重复峰值浪涌电流能承受较短时段的冲击电流（如充电、浪涌脉冲）。
- 宽温度范围：-55°C 至 +150°C，适应工业级环境。
四、典型应用场景
- 开关电源输出整流与保护
- 高压直流供电与整流模块
- 电表、仪器电源及控制电路的反向保护
- 开关器件防反接、吸收回路与瞬态抑制（配合限流元件使用）
五、封装与安装注意
SMA（DO-214AC）表面贴装封装适合集成化 PCB 设计。推荐注意事项：
- PCB 焊盘按供应商建议尺寸设计以保证良好焊点与热散布；
- 在高电流或高浪涌环境下，考虑加宽铜箔或添加热过孔以降低温升；
- 焊接温度与回流曲线应符合封装工艺规范，避免过热引起器件降额。
六、热管理与可靠性
连续电流 800mA 在高环境温度或散热不足时会导致结温上升，应评估实际功耗（Pd ≈ Vf × IF）并采取散热措施。长期可靠性受焊接工艺、工作结温与环境应力影响，建议在系统设计时留有安全裕度并做足温升验证。
七、选型与使用建议
- 若电路存在频繁或大幅浪涌，优先评估浪涌能量与是否需并联或选用更高 Ifsm 器件；
- 对功率损耗敏感的场合，可比较低 Vf 的肖特基二极管，但肖特基通常耐压不及 1kV；
- 采购时确认批次与规格一致性，必要时索取器件参数表（Datasheet）与可靠性报告。

Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
