DSR1M 产品概述
一、产品简介
DSR1M 是 CJ（江苏长电/长晶）推出的一款通用高压整流二极管，采用 SOD-123FL 贴片封装，面向中小功率高压整流与保护场景设计。器件以稳定的电气性能与小型化封装适配现代电源与工业电子应用。
二、主要参数
- 正向压降 (Vf)：1.0 V @ 1 A
- 直流反向耐压 (Vr)：1000 V
- 连续整流电流 (Io)：1 A
- 反向电流 (Ir)：5 μA @ 1000 V
- 非重复峰值浪涌电流 (Ifsm)：30 A
- 工作结温范围：-55 ℃ ~ +150 ℃
- 封装：SOD-123FL（小型贴片）
三、产品亮点
- 高压能力：1000 V 反向耐压适合高压整流与隔离场景。
- 低反向漏流：5 μA（@1000 V）保证在高耐压下依然具备良好的泄漏控制，有利于高阻断电路的可靠性。
- 小体积高可靠：SOD-123FL 封装兼顾尺寸与散热，适合密集贴片安装。
- 抗浪涌性能：30 A 峰值浪涌电流可以承受瞬态冲击，增强系统抗脉冲能力。
四、典型应用
- 开关电源与整流桥电路的高压整流单元
- 高频电源、逆变器及电源模块的保护与整流
- 工业控制、仪器仪表及消费电子的极性保护与钳位
- 高压检测、偏置电源及飞返型电源应用
五、封装与电气设计建议
SOD-123FL 有利于快速回流焊生产，建议按 IPC/JEDEC 推荐的回流曲线作业，合理设计焊盘尺寸与热沉铜箔，以改善结温上升。若在高功耗或限流工况下使用，建议在 PCB 上加入散热铜箔和过孔以降低结温。
六、可靠性与注意事项
- 避免长期在高结温或超额电流条件下工作，以延长器件寿命。
- 在高压测试或应用中，注意爬电距离与绝缘设计，防止表面击穿或串扰。
- 储存与回流焊须遵循湿敏等级与制造商推荐的工程规范。
DSR1M 以其 1 A 连续电流、1 kV 耐压与小型封装，为需要高压、低漏电且节省 PCB 面积的方案提供了可靠且成本合理的选择。若需进一步的电气曲线、封装图或推荐焊盘，请告知以便提供详细资料。
Request for quote
Send RFQ
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.
