GS1MA 整流二极管 产品概述
一、产品简介
GS1MA 是江苏长电/长晶（CJ）推出的一款高电压单体整流二极管，封装标识为 SMAG。器件为独立式单个二极管，面向需要高反向耐压与中等整流电流的电源与高压整流场合，兼顾浪涌承受能力与宽温工作范围。
二、主要参数
- 二极管类型：单只独立整流二极管
- 直流整流电流（If）：1 A
- 正向压降（Vf）：约 1.0 V @ 1 A
- 直流反向耐压（Vr）：1 000 V（1 kV）
- 反向漏电流（Ir）：5 μA @ 1 000 V
- 非重复峰值浪涌电流（Ifsm）：30 A（一次性尖峰浪涌）
- 工作结温范围：-55 ℃ ~ +150 ℃
三、主要性能与特性
- 高耐压：1 kV 的反向耐压使其适用于高压整流链、倍压电路与偏压电源。
- 低漏电：在额定耐压下反向漏电仅为 μA 级，有利于高压偏置与高压测量电路的稳定性。
- 中等整流能力：1 A 的持续整流电流适合小功率电源和整流模块。
- 良好浪涌承受：30 A 的非重复峰值浪涌能力可以应对启动或瞬态冲击，但不宜长期以浪涌方式工作。
- 宽温区间：-55 ℃ 至 +150 ℃ 的结温区支持工业级环境使用。
四、典型应用场景
- 高压整流电源、倍压整流（Cockcroft–Walton）电路
- 工业测量与偏置电源、高压探测前端
- 小功率开关电源的高压侧整流与反馈电路
- 高频脉冲供电或需承受瞬态浪涌的电源保护电路
五、封装与安装建议
- 封装：SMAG（厂方封装命名），具体外形与尺寸请参照厂商规格书。
- 安装建议：采用合适的焊接工艺和 PCB 铜箔散热设计，保证良好热路径；若在空气中散热不足，应采用更大铜面或散热片辅助。
- 机械与布局：高压引线与周边电路布局需保持足够爬电距离与绝缘间隙，防止表面放电。
六、热与可靠性注意事项
- 在高结温下正向压降、反向漏电均会上升，应进行功率与温度的降额设计。
- 长期工作中避免频繁超过 Ifsm 的冲击；若有重复大电流脉冲，建议选用更高 Ifsm 的型号或并联设计（并联需注意均流）。
- 出于可靠性与合规性考虑，采购前请确认是否满足 RoHS / REACH 等环保要求及批次测试数据。
七、选型与替代建议
- 若需要更低 Vf 或更高整流电流，可考虑肖特基（Schottky）或更大电流的整流二极管（注意耐压通常较低）。
- 若系统以高能量脉冲为主，应优先选用更高 Ifsm 或专用脉冲整流器件。
- 选购时以厂方最新数据手册为准，确认浪涌、热阻与包封材料等完整参数。
八、结语
GS1MA（CJ，SMAG 封装）是一款面向高压、小功率整流的实用器件，具有 1 kV 的强耐压与较低的反向漏电，适合工业高压电源与偏置应用。合理的热设计与电气降额能显著提升长期可靠性；具体电路接入与细节请参照厂家规格书与样片测试结果。

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.
