G1M 产品概述
一、产品简介
G1M 是鲁光（LGE）推出的一款通用高压整流二极管，封装为 SOD-123FL 贴片形式。该器件设计用于承受高达 1kV 的反向电压并在 1A 直流工作电流下保持稳定整流性能，具有低正向压降与较小反向漏电流，适合空间受限且需高压耐受的应用场景。
二、主要电气参数
- 正向压降 (Vf)：1.1V @ 1A
- 直流反向耐压 (Vr)：1000V
- 直流整流电流：1A
- 反向电流 (Ir)：5μA @ 1kV
- 非重复峰值浪涌电流 (Ifsm)：25A（一次性浪涌能力）
- 工作结温范围：-55℃ ~ +150℃
以上参数表明 G1M 在高压工作点下仍保持较低的漏电与合理的正向损耗，适合需要高压耐受但电流级别不大的电源与整流场合。
三、封装与可靠性优势
G1M 采用 SOD-123FL 小外形贴片封装，优点包括：
- 占板面积小，利于高密度布局与自动化贴装；
- 热阻受限但足以支持 1A 等级的连续整流；
- 封装适配常见回流焊工艺，良好的机械强度与焊接可靠性。
器件额定的-55℃~150℃结温范围为工业级应用提供了温度裕量，有利于在苛刻环境下长期可靠工作。
四、典型应用场景
G1M 适用于多类需要高压耐受的中小功率电路，例如：
- 离线开关电源（高压整流与次级保护）；
- 高压脉冲电路与倍压整流器（如电容充电回路）；
- 工业仪器与测试设备的高压整流；
- 小功率电源模块、LED 驱动及整流保护等。
在设计中可用于高压侧的通用整流、反向保护或作为耐压要求较高的钳位元件。
五、设计与使用建议
- 布局：高压端走线留有足够绝缘距离，避免爬电与电晕放电；焊盘与走线应保证可靠的散热通道；
- 热管理：虽然 SOD-123FL 封装便于散热，但在连续 1A 工作或高环境温度下应考虑增加铜箔面积或散热方式以控制结温；
- 浪涌保护：Ifsm = 25A 适合一次性浪涌场景，但不宜在频繁大浪涌环境下长期依赖；必要时配合限流或热熔断元件；
- 工艺：推荐使用标准回流焊工艺；为确保可靠性，请参照鲁光提供的焊接与储存规范。
六、包装与采购信息

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.
