1N4002 通用二极管产品概述
概要
1N4002 是一种通用二极管，属于YONGYUTAI（永裕泰）品牌的产品系列。它以其稳定可靠的性能和广泛的应用场景，在电子行业中得到广泛认可。以下是对1N4002通用二极管的详细介绍。
基础参数
- 二极管配置: 独立式
- 反向电流（Ir）: 5μA @ 100V
- 商品分类: 通用二极管
- 整流电流: 1A
- 正向压降（Vf）: 1.1V @ 1A
- 直流反向耐压（Vr）: 100V
封装
1N4002采用SMA（DO-214AC）封装，这是一种小型化的封装形式，适用于空间有限但需要高性能的应用场景。SMA封装的尺寸较小，易于在紧凑的电路板上安装和布线。
电气特性
正向压降（Vf）
1N4002在1A的整流电流下，正向压降为1.1V。这意味着当通过二极管的电流达到1A时，二极管两端会有约1.1V的电压降。这种特性使得它适合用于各种需要低损耗的整流应用。
反向耐压（Vr）
该二极管具有100V的直流反向耐压，这意味着在正常工作条件下，它可以承受高达100V的反向电压而不发生击穿或损坏。这种高耐压能力使其在许多高压应用中非常有用。
反向漏电流（Ir）
在100V的反向电压下，1N4002的反向漏电流仅为5μA。这表明该二极管在反向偏置状态下具有极低的漏电流，确保了在大多数应用中不会出现不必要的能量损失。
应用场景
1N4002通用二极管由于其良好的电气特性和小型化封装，适用于各种电子设备和系统，包括但不限于：
- 电源整流: 用于将交流电转换为直流电的电源供应器中。
- 过压保护: 作为过压保护元件，防止设备受到高压冲击。
- 信号整形: 在信号处理电路中用于整形和滤波信号。
- 开关电源: 在开关模式电源中用于实现高效能量转换。
- 汽车电子: 适用于汽车电子系统中的各种应用，如点火系统、照明系统等。
优势
- 高耐压能力: 100V的直流反向耐压使其在高压环境中非常可靠。
- 低正向压降: 1.1V @ 1A的正向压降减少了能量损失，提高了系统效率。
- 小型化封装: SMA封装使其易于在紧凑空间中安装和布线。
- 低反向漏电流: 5μA @ 100V的反向漏电流确保了低能量损失和高效能工作。
安装注意事项
在安装1N4002时，需要注意以下几点：
- 确保正确的极性连接，以避免反向偏置导致的损坏。
- 避免过热，确保良好的散热条件。
- 使用适当的焊接技术，以防止因焊接不当导致的损伤。
总结
1N4002通用二极管是YONGYUTAI（永裕泰）品牌的一款高性能产品，通过其优异的电气特性和小型化封装，广泛应用于各种电子设备和系统。其高耐压能力、低正向压降和低反向漏电流使其成为许多设计工程师的首选。无论是在电源整流、过压保护还是信号处理等领域，1N4002都表现出其卓越的性能和可靠性。

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.
